todays non event update

You can feel the sky wanting to do something with some light precip falling, but nothing is reaching the ground. And when I say light, you almost don't notice it.
 
I’ll amend that a little - some coating on car tops and sidewalks, but not much.
 
I expect a little snow today because my bird feeders were 100% booked this morning. Was getting some flurries about 30mins ago out here about 5mins from Del. River.
Coating of snow here in Linden now.
 
early January 2014 was quite cold actually it was the 7th and 8th time frame, we had a funeral for my great aunt and the temps at 10AM was like 7 degrees with alot of wind so only a few strong men went to the actual site for the burial leaving the women and old folk behind at the church. Remember stretch of days in the teens for highs, that may be the last sustained frigid we had but I could be wrong on that..i know we have had other days in the teens for highs since.

The first frigid episode began on the 3rd, when late in the evening Walpack (Sussex) dropped to -12° and Pequest (Warren) reached -8°. By the morning of the 4th the temperature bottomed out at -13° in Walpack and -12° at Pequest. Kingwood (Hunterdon) was -10° and 28 other stations dropped below zero on the 4th. The “mildest" location in the state was Atlantic City Marina (Atlantic) at 13°. Walpack fell to -8° on the 5th and Pequest -5°.

Following the brief warm up on the 6th, minimums again fell below zero at some locations on the 7th, including -6° at High Point Monument (Sussex) and -5° at High Point (300 feet lower than the Monument station). Accompanying the cold on the 7th was strong wind that resulted in dangerous wind chills as low as -27° at the Monument at 11 AM, when the temperature was -4° with a wind speed of 20 mph. Wind chills of -10° to -20° (colder in gusts) were common across NJ during the daylight hours of the 7th, when thermometers across most of the state sat in the single digits. For instance at noon, temperatures ranged from -3° at High Point Monument to 12° in West Cape May (Cape May). These were the coldest daylight hours in NJ since January 19, 1994. The cold continued into the 8th, with lows of -4° at Walpack and -3° at the Monument, an interesting pair of minimums. The cold at Walpack is indicative of cold air pooling in valleys while High Point Monument is often the coldest location when cold air sweeps into the region, with winds at these times stirring up the lower atmosphere and minimizing cold air drainage into valleys.
That was a really cold stretch with that January being the 18th coldest in NB's 130 year weather history with an avg temp of 25.5F.. I remember how cold it was on the 7th as my car battery died and it was so cold trying to give it a jump that it took awhile. I don't remember temps like that - only snow, lol. 2013-2014 was a winter that snow lovers loved with 56.4" in NB (we got about 59" here) and a well below normal Jan/Feb. Interesting that it's looking like a lock that this winter will be the first one in several years with a below average Dec/Jan; 2017-18 and 2009-10 were the last two winters with below normal temps for DJF. Looking like most suburbs will make a run at 0F on Tues/Weds mornings.

No. Not cold enough Sunday.
Looking pretty snowy as of now, although still time for that to change. I would think that favors the Eagles and their running game a bit. I do love watching a game in the snow, though. My dad/sis/bro in FL will be cheering the Iggles on.
 
not bad

Hard to argue that the Eagles running game (with or without snow) as Barkley had over 200 yards running against the Rams a few months ago in LA.
I think measurable snow as a benefit to the home team is overated. Of course there has never been a snow game in LA but I can't think of the last snow game at the Linc. Most of the current Eagles have never played in snow in Philly. Nor have they practiced in snow here this year. Philadelphia snow total this season is a paltry 2.5 inches.
The huge benefit is the cold. It didn't come close to 30 degrees as the Eagles practiced in flurries at times. Meanwhile the Rams were seen practicing in shorts yesterday.
All I ask for is a good game. NFL and College playoffs this season have mostly been a disappointment entertaining wise. Lots a games over before 4th quarter.

I guess yesterday really did overperform, lol. Those NWS maps are "live," defaulting to the most recent version anywhere it's been poste as a link to the NWS page, which is why I've had to go to imgur to host all the graphics I post, as they're actual picture files not hot links. It's annoying.
 
Looking ahead, it's not looking as good for snow for this area next week, mostly due to suppression of any storm systems to the south from the very strong high pressure/cold air we'll have in place for the brutal cold snap Monday through Friday. The CMC has the 1/22 system, which might hammer the SE US, just missing us, while the Euro and GFS have that system further offshore. Still time for adjustments for us or for a system to pop up on 1/24-25 as has been seen on a few long range model runs, as that's when the blocking relaxes and things start to warm up - and that regime has been associated with significant snowfalls in the past, so it ain't over yet.

But the 1/21-22 SE US storm is no longer in fantasy land as we're now within 4 days of the start of the event in Texas. The CMC has been on this for days and the Euro/GFS are also on it, so even the NBM model blend is showing a decent snowstorm. Houston's biggest snowfall ever was 20" in Feb 1895 and so was New Orleans's with 8.2", but they haven't had measurable snow in 15 years. Not a done deal yet, but it's looking like snow from TX to the Carolinas including much of the immediate Gulf Coast. Crazy for this region.

yet not sure why they do that even if its posted already
 
Summary: First pattern thread of the winter. Just about every medium/long range model (especially the ensembles of the GFS, CMC and Euro, which are used most for trend forecasts beyond about 7-8 days) continues to show (as mentioned in the Christmas Eve snow thread) a major pattern shift to a cold to possibly very cold regime starting by next weekend, with multiple possible storm systems after that, some of which could bring snow (possibly substantial amounts) to the eastern US and our area for much of January. And just about every well-known meteorologist is honking about the upcoming pattern change. Yes, I know it's usually relatively cold and snowy in January, but we're talking likely colder than normal (and possibly much colder than normal - especially in the SE US) and snowier than normal (NB gets about 8-9" of snow, on average in Jan) from about 1/4 through 1/25 and given the paucity of snow for most the past 3 winters this is noteworthy. The cold looks like a lock, at least through mid-Jan, while the snow is always much iffier to predict more than a week in advance, so we'll wait and see. And based on the @e5fdny weather clause, any specific storms that materialize will be covered in separate threads when and if they look real (usually 4-5 days out), with the first possible threat around 1/6. Hope some find this interesting.

Details: The video link, below, from John Homenuk one of the best medium/long-range forecasters out there explains the meteorology behind the pattern change much better than I could, but briefly, instead of the warm pattern we expect to have for the next week, which features strong west to east jet stream flow from the mild Pacific across the US, a strong ridge is forecast to build from Cali to Alaska forcing the jet stream to ride up and over it and then down east of the Rockies, bringing very cold polar air down from Canada into the eastern half of the US, plus high latitude "blocking" is expected with another strong ridge up in NE Canada/Greenland acting to "hold" the cold air in place in the eastern US and to slow down the storm systems that are expected to rotate through the eastern US from about 1/5 onward.



With regard to the teleconnections, which are often used to forecast long range patterns, we're forecast to have the weak La Nina continue and to have the MJO (Madden-Julian Oscillation) move into phases 8 and 1 (associated with cold/snowy here) and to have a sustained combination of a -AO (Arctic Oscillation) and +PNA (Pacific/North America), which is the combo we've had for ~50% of 6"+ snowstorms in NYC, as per the famed DonSutherland on AmericanWx (see his graphic below and his post linked below), plus we'll also likely have a -NAO (North Atlantic Oscillation) and a -EPO (Eastern Pacific Oscillation). Cold air in place, plus moisture from storms could mean significant snow, although it's still too early to predict specific storms (but they are showing up on the long range guidance) and it's always possible the cold/snow just don't work out, as very cold air can suppress storms to our south or if the cold air weakens for a bit, a storm could always cut west of us bringing mix/rain. DT/WxRisk does a great job explaining all of the teleconnections in the video link below.

In addition, NOAA's Climate Prediction Center (CPC) is on board for colder than normal weather for much of the eastern US from 1/4-1/10 (with normal precip amounts) and is also predicting colder and wetter than normal conditions from 1/11 through 1/24 in their Weeks 3/4 forecast; just showing the temp graphics below. FYI, I only did one pattern thread last winter, for a warm/low snow first half of Feb, which verified, followed by a cold and potentially snowy period after that, which did not verify at all for cold, but did verify for above normal snowfall for most from 2/12-2/17. Overall, since 2017 I've done 1-2 pattern threads per winter, featuring 10 of 13 temperature patterns verifying and 9 of 13 snowfall patterns verifying (with below normal, normal and above normal as possible outcomes, random guessing would mean 4 out of 13 verifying). That means the pros kind of know what they're doing.

Summary: So, the likely colder than normal and potentially snowier than normal period from 1/4 through 1/25 for our area, which I posted about on 12/28, has now come and gone and it was quite cold (4.7F below normal in New Brunswick), but was only slightly above average in snowfall (5.2" in NB vs. 5.0" for 22 days in Jan on average), due to simple lack of precipitation; I use NB as a decent, but imperfect representative for the Philly-NJ-NYC area. Given the way I "score" these pattern threads, colder than normal is being in the bottom 1/3 of January's and 4.7F places this period in 22nd out of 132 years of NB records, so colder than normal verified. Snowier than normal, however, did not verify for NB, as the snowiest 1/3 of January's would've had 5.6" or more of snow vs. the 5.2" that fell.

However, the "pattern" certainly provided well above normal to record snowfalls for most of the eastern US south of 40N, but not for most areas north of 40N, so it was a very near miss for our area, although most winter weather nuts were still pretty happy with 4-7" of snow during this period (we got 5.7" in Metuchen) and especially the 1/20 snow and cold that followed, providing a beautiful snowscape all this past week. It certainly made for lots of fun at our weekly soccer match today. Peeking ahead, there could be some wintry weather 2/1-2/2, but right now it's looking more wet than white (except well NW of 95), but we're far enough out for that to change. Lots of good discussion about the entire month of January with regard to the pattern, snow/precip, temps, and this weekend's storm in the thread below from AmericanWx.

https://www.americanwx.com/bb/topic/61402-january-2025/

Details: Specifically, with regard to temperature for our area, 1/4-1/25 was about 4.7F colder than normal in New Brunswick (the location I use for these pattern discussions as I simply don't have time to evaluate many locations and NB is a good indicator for at least CNJ if not the 95 corridor from Philly to NYC and a bit beyond), which puts this period firmly into the bottom 1/3 of Januarys, which is what I would call "colder than normal" with the other two outcomes, obviously, being normal (middle 1/3 of outcomes) and above normal (top 1/3). 4.7F colder than normal is 26.1F vs. a mean Jan temp of 30.8F, which puts this period at about the 22nd coldest in the 132 year recorded weather history for NB (bottom third would be 1st thru 44th coldest). Only 5 days during this period were above normal and the last 5 days of the period averaged 15F below normal, which is seriously cold.

With regard to snowfall for our area, again using NB as the measuring stick, NB got 5.2" of snow from 1/4-1/25 (1.2" on 1/6, 0.5" on 1/11, 0.3" on 1/16, and 3.2" on 1/20) and on average NB gets 7.1" of snow in January, so for 22 of 31 days, one would expect 5.0" of snow in NB, placing this year just slightly above average, but certainly not in the top 1/3 of January's (required for me to call the period snowier than normal), as the top 1/3 had snowfalls >5.6" (pro-rated for 22 of 31 days in Jan). Most locations in our area (Philly-NJ-NYC) got close to average snowfall for the period, with the exception being far SNJ, which got 6"+ just from the 1/6 storm. The table linked below summarizes the 132 year weather record for NB, including temps and snowfall.

https://climate.rutgers.edu/stateclim_v1/monthlydata/index.php?stn=286055&elem=snow

Looking back at this period, it was obviously cold enough for there to be substantial snow, not only in NB and our area, but across most of the eastern half of the US, as temps were also generally below normal to well below normal for the eastern U for this period. But unfortunately for snow lovers, the Philly-NJ-NYC area (apart from far SNJ), just didn't get enough precip to provide above normal snowfall. Same was generally true for all of the NE US, but clearly was not true roughly south of the 40N parallel, as much of the eastern US south of that line was impacted by two snowstorms during this period.

The first was a major storm that hit much of VA/MD/DE/SENJ/NC/TN/KY (and even northern AL/MS/GA) with 4-12" on 1/6 and the second was the historic storm last week that set snowfall records all across the Deep South from TX to NC, including all-time snowfall records in places like New Orleans, Mobile, and Pensacola (and the biggest snowfall ever in Florida, 9.8" in Miton). So the "pattern" certainly delivered above to way above average snowfall south of 40N, but not for areas N of 40N, in general. Note that the graphic below is snowfall for the entire winter through 1/25, but that all of the snow that fell for areas south of 40N fell during the 1/4-1/25 period, whereas some of the snow for our area and the NEUS fell in December (especially well NW of 95 where major snows fell).

Looking more closely at the precipitation our area received during this period, this January overall is likely to end up being the driest January on record for many, including NYC, Newark, New Brunswick and Philly, all of whom have had <0.5" of precip this month, so far, with little to none expected through the end of the month unless this weekend's storm arrives late Friday and puts down >0.1" of precip before 2/1, as each location only needs about another ~0.1" of precip to not be the driest January ever. We might get a few rain/snow showers on 1/29 and that's about it, as the next storm likely doesn't make it here until 2/1, although some models are showing a late Friday arrival with rain on all of the models into 2/1, but some showing some snow possible later on 2/1 into 2/2. Note that the very dry January extended well into New England, also. As an aside, the lack of precip in January means that most of our area's drought situation has worsened again after a fairly wet December.

Looking Ahead: This coming week looks seasonable with most days having high temps anywhere from the mid-30s to mid-40s and the following week looks fairly similar temp-wise, while forecasts are calling for fairly normal to maybe a bit above normal precip, but no torch or deep freeze patterns look likely for at least the next 2-3 weeks. With regard to snow threats, there could be a dusting S of 80 on Wednesday with up to 1" N of 80 from a weak clipper system and then all eyes turn to this weekend, when a more substantial storm takes aim at our area with the potential for 1-2" of precip from late 1/31 through the weekend. Currently all but one of the global models shows that being almost all rain (with some snow N of 80 and more substantial snow N of 84), but the GFS is showing decent snowfall down to 276/195 after 1"+ rain, so there are scenarios where this system could turn out a bit more snowy. Way too early for a thread, plus I'll be in Florida from 1/29-2/4, so for this one, I'll be rooting for rain, lol, as I hate missing snowstorms while I'm away.

Accuracy is questionable, as far as that NW corner of NC. We've had 30"+ so far on our perch above Boone in Watauga County. Wishing and hoping the very worst of it is behind us.

It's not inaccurate, it's simply that a zoomed out graphic can't show that level of detail well. It's hard to see, but that area of WNC does show very iight red, which is in the 28-36" range. You can see it a bit better in the zoomed in graphic for NC/VA, but haven't looked yet for a graphic just for WNC for the season to date.

Summary: So, the likely colder than normal and potentially snowier than normal period from 1/4 through 1/25 for our area, which I posted about on 12/28, has now come and gone and it was quite cold (4.7F below normal in New Brunswick), but was only slightly above average in snowfall (5.2" in NB vs. 5.0" for 22 days in Jan on average), due to simple lack of precipitation; I use NB as a decent, but imperfect representative for the Philly-NJ-NYC area. Given the way I "score" these pattern threads, colder than normal is being in the bottom 1/3 of January's and 4.7F places this period in 22nd out of 132 years of NB records, so colder than normal verified. Snowier than normal, however, did not verify for NB, as the snowiest 1/3 of January's would've had 5.6" or more of snow vs. the 5.2" that fell.

However, the "pattern" certainly provided well above normal to record snowfalls for most of the eastern US south of 40N, but not for most areas north of 40N, so it was a very near miss for our area, although most winter weather nuts were still pretty happy with 4-7" of snow during this period (we got 5.7" in Metuchen) and especially the 1/20 snow and cold that followed, providing a beautiful snowscape all this past week. It certainly made for lots of fun at our weekly soccer match today. Peeking ahead, there could be some wintry weather 2/1-2/2, but right now it's looking more wet than white (except well NW of 95), but we're far enough out for that to change. Lots of good discussion about the entire month of January with regard to the pattern, snow/precip, temps, and this weekend's storm in the thread below from AmericanWx.

https://www.americanwx.com/bb/topic/61402-january-2025/

Details: Specifically, with regard to temperature for our area, 1/4-1/25 was about 4.7F colder than normal in New Brunswick (the location I use for these pattern discussions as I simply don't have time to evaluate many locations and NB is a good indicator for at least CNJ if not the 95 corridor from Philly to NYC and a bit beyond), which puts this period firmly into the bottom 1/3 of Januarys, which is what I would call "colder than normal" with the other two outcomes, obviously, being normal (middle 1/3 of outcomes) and above normal (top 1/3). 4.7F colder than normal is 26.1F vs. a mean Jan temp of 30.8F, which puts this period at about the 22nd coldest in the 132 year recorded weather history for NB (bottom third would be 1st thru 44th coldest). Only 5 days during this period were above normal and the last 5 days of the period averaged 15F below normal, which is seriously cold.

With regard to snowfall for our area, again using NB as the measuring stick, NB got 5.2" of snow from 1/4-1/25 (1.2" on 1/6, 0.5" on 1/11, 0.3" on 1/16, and 3.2" on 1/20) and on average NB gets 7.1" of snow in January, so for 22 of 31 days, one would expect 5.0" of snow in NB, placing this year just slightly above average, but certainly not in the top 1/3 of January's (required for me to call the period snowier than normal), as the top 1/3 had snowfalls >5.6" (pro-rated for 22 of 31 days in Jan). Most locations in our area (Philly-NJ-NYC) got close to average snowfall for the period, with the exception being far SNJ, which got 6"+ just from the 1/6 storm. The table linked below summarizes the 132 year weather record for NB, including temps and snowfall.

https://climate.rutgers.edu/stateclim_v1/monthlydata/index.php?stn=286055&elem=snow

Looking back at this period, it was obviously cold enough for there to be substantial snow, not only in NB and our area, but across most of the eastern half of the US, as temps were also generally below normal to well below normal for the eastern U for this period. But unfortunately for snow lovers, the Philly-NJ-NYC area (apart from far SNJ), just didn't get enough precip to provide above normal snowfall. Same was generally true for all of the NE US, but clearly was not true roughly south of the 40N parallel, as much of the eastern US south of that line was impacted by two snowstorms during this period.

The first was a major storm that hit much of VA/MD/DE/SENJ/NC/TN/KY (and even northern AL/MS/GA) with 4-12" on 1/6 and the second was the historic storm last week that set snowfall records all across the Deep South from TX to NC, including all-time snowfall records in places like New Orleans, Mobile, and Pensacola (and the biggest snowfall ever in Florida, 9.8" in Miton). So the "pattern" certainly delivered above to way above average snowfall south of 40N, but not for areas N of 40N, in general. Note that the graphic below is snowfall for the entire winter through 1/25, but that all of the snow that fell for areas south of 40N fell during the 1/4-1/25 period, whereas some of the snow for our area and the NEUS fell in December (especially well NW of 95 where major snows fell).

Looking more closely at the precipitation our area received during this period, this January overall is likely to end up being the driest January on record for many, including NYC, Newark, New Brunswick and Philly, all of whom have had <0.5" of precip this month, so far, with little to none expected through the end of the month unless this weekend's storm arrives late Friday and puts down >0.1" of precip before 2/1, as each location only needs about another ~0.1" of precip to not be the driest January ever. We might get a few rain/snow showers on 1/29 and that's about it, as the next storm likely doesn't make it here until 2/1, although some models are showing a late Friday arrival with rain on all of the models into 2/1, but some showing some snow possible later on 2/1 into 2/2. Note that the very dry January extended well into New England, also. As an aside, the lack of precip in January means that most of our area's drought situation has worsened again after a fairly wet December.

Looking Ahead: This coming week looks seasonable with most days having high temps anywhere from the mid-30s to mid-40s and the following week looks fairly similar temp-wise, while forecasts are calling for fairly normal to maybe a bit above normal precip, but no torch or deep freeze patterns look likely for at least the next 2-3 weeks. With regard to snow threats, there could be a dusting S of 80 on Wednesday with up to 1" N of 80 from a weak clipper system and then all eyes turn to this weekend, when a more substantial storm takes aim at our area with the potential for 1-2" of precip from late 1/31 through the weekend. Currently all but one of the global models shows that being almost all rain (with some snow N of 80 and more substantial snow N of 84), but the GFS is showing decent snowfall down to 276/195 after 1"+ rain, so there are scenarios where this system could turn out a bit more snowy. Way too early for a thread, plus I'll be in Florida from 1/29-2/4, so for this one, I'll be rooting for rain, lol, as I hate missing snowstorms while I'm away.

So I’m in Hamilton NJ. Is that map saying I had 8.2” of snow this season? No way that’s true.

The "pattern" was accurate for the cold but way off in snow and in general precipitation. I still don't understand the late addition the morning of the last storm at the same time it was 39 degrees when the new map was released. Right now Philly and the general area will be the lowest total ever in Philadelphia if we don't get anymore rain/snow before Saturday.

Since it was accurate about the cold the extra snow comes off the table. Hello suppression my old friend…😎
 
But the "pattern" said both were coming
True. To be fair, if last weekend’s storm threaded the needle better, both would’ve been true, but it didn’t. Patterns aren’t certainties and I’m glad it didn’t verify as I’m not a big fan of snow.

I like snow but hate shoveling lol. So no snow is fine for me!
 
So I’m in Hamilton NJ. Is that map saying I had 8.2” of snow this season? No way that’s true.
accurate but remember its basically counting official snowfall on a coldest surface...you had minor accumulations on grass that led to less than half or sometimes nothing on paved roads

For Philadelphia, the pattern was accurate for being colder than normal and a little off for snow, relative to it being "snowier than average," as snowfall for the period was right on the average, not "way off;" details below Total precip was way below normal, but that wasn't part of the original post. For the last storm, the NWS saw the early morning models all bump up snowfall amounts appreciably, so they raised the snowfall forecast a bit - that ended being wrong, but I wouldn't say it was unjustified given the data at hand.
  • For temps, Philly was 6.4F below normal for the 1/4-1/25 period, which is way below normal (vs. the Jan avg of 41/28F), as it was the 2nd coldest January in the last 30 years and the 13th coldest in the 84 years since 1941 (when records started being kept at the airport) and was even a bit colder than NB's 4.7F below normal for the same period.
  • For snow, Philly got 4.6" from 1/4-1/25 (at the airport, the official location of record since 1941) and this is just about average for that period, as Philly gets 6.4" in January on average, so over 22 days one would expect 4.5" of snow - that's not way off.
  • For precip as I mentioned above, Philly might have a record low for January as they have 0.39", so far vs. a lowest ever of 0.45". I also never made any predictions about total precip, just cold and snow.
 
yep big long thread which basically failed...BELOW NORMAL SNOWFALL FOR THE PERIOD
Wrong. Snowfall was not below normal in New Brunswick as I demonstrated (it was slightly above normal, but not enough to meet my criteria of "above normal" where that is being in the top 1/3 of historical data) and NB is pretty representative of CNJ. I'm sure there are locations where snowfall was below normal and some above, but most were pretty close to normal, as far as I can tell.

Edit - and in my response to WB, I also showed that Philly's snowfall was about average for the 1/4-1/25 period. So again, not below normal in another major location.

Do you forget the last map you posted last Sunday that had over 5.5in in Philadelphia while it was 39 degrees and we got 2.0 officially and less in Center City? Your pattern was only accurate by temps not by snow in Philly. Stop moving the bar!

Please just stop posting nonsense. My thread was for cold/snow from 1/4-1/25 and Philly was right on average for that period, which is still a miss vs. what I said could happen in the pattern, but the snow was NOT below normal for that period. This thread has 0.0 to do with the forecast for Philly being too high for snow on 1/19.

Nonsense? Comes from you! You have to to protect your stupid thread. You are wrong about average. Philadelphia is below average for the entire season.
This thread is exactly a problem that you posted a Map last Sunday that increased snow fall at the same time it almost 40 degrees! Damn, you can never be wrong!! But you think you are.
I was looking forward to seeing everyone for a much needed love fest for Dave Rosenthal passing. The crap in that thread about, which you are contributing to, about heart attacks info, taking away from Dave is another example about your need to be right.

You know he is just posting what the NWS is forecasting. If you and Bac are not interested, you can just ignore the thread.

No he will be the first to admit he loves snow so he only post favorable snow posts. If you don't like my posts put me on ignore. I can give a rats ass what you think

More nonsense. For the tenth time, the thread was about cold and snow from 1/4 through 1/25. Can you understand that? And for that period, Philly got 4.6" at the airport vs. the 4.5" that would be expected at the airport, on average, for those 22 days. So snowfall was normal for that period. I never said anything about what Philly snowfall would be for the whole winter - do you understand that?

The map I posted the morning of the 1/19 event wasn't "my" map - it's like you're blaming me for posting the most up-to-date map from the NWS, the foremost authority on weather for the region. Plus, I've already said I was wrong in the prediction of above normal snowfall for this pattern, so I have zero issue saying I was wrong about something. It's not a big deal at all for me, especially when this is supposed to be just for fun and info.

And I would have never imagined there being an issue with what I posted in the Rosenthal thread. I posted my condolences and shared that one of my best friends recently died too young from a heart attack, also. People share their stories on the board. Then, GOR quoted me and kind of speculated on whether heart attacks might be increasing in recent years - so I posted some info on heart attacks in response. I never thought anyone would have an issue with that - if you or others have an issue, ask the mods to delete the posts by me and others that are talking about heart attacks in general.

Yet you say that Philly was average?? It was Historical low.
Start a heart issue in another thread.
You posted a Map that was incredibly wrong and you knew it.
People share there stories on here but some should stay on topic. I'm guessing you won't be there Wednesday

Now you're either trolling or are incapable of understanding basic math, so I'll assume trolling. 4.6" actual vs. a 4.5" average over the period I am posting about is obviously not an "historical low."

How could I post a map I "knew" was wrong many hours before the event started? You think I actually "knew" what was going to happen? That's ridiculous. I post just about every map the NWS comes out with, twice a day, as the most recent map is usually their best. It wasn't this time. Sue them if you don't like it, but stop giving me crap about it.

No, I won't be going to the memorial. I don't typically go to funerals/memorials for people I don't know, plus we're flying to Florida that morning anyway. I will make a donation, though, to the charity mentioned in his name, since it sounds like he was a class act and great Rutgers fan and family man. And again, have the mods delete posts not about Dave in that thread, if you think that's appropriate - I care nothing about the posts I or others made about heart attacks in that thread.

Where are you getting 4.5" for the month of January in Philadelphia.
Also I'm talking about total precipitation not just snow. Yes it's a historic low currently. It's on every news station in Philly. We are still in drought here.
I knew the map was wrong the second I stepped out of the house. It was supposed to be that warm at that time.
