You having Glenn Close over for dinner?
Yep, 80-90% sleet for Trenton to NYC, but only about 1" of total liquid equivalent precip, so that's maybe 0.7" of LE as sleet (2" of sleet, after 1" of snow - which is the equivalent of 8" of snow in mass), which is way less than the 1.5-2.0" amounts on almost every other model. GFS still has 3-4" snow, then some sleet then a lot of rain; same for the CMC, with less snow, but more sleet. Going to be a crazy storm.
And one more thing to keep in mind is that sleet pellets have far lower surface area per unit volume (mass) than snow flakes, meaning that far less surface area is exposed to the ambient temp, such that they'll take a lot longer to melt from road warmth and surface temps in general (and indirect sunlight) - it's like the difference between ice cubes melting in a water glass vs. ice shavings - cubes melt far more slowly.
Therefore, sleet is much worse for roads than snow with regard to melting and similar to snow, per unit accumulated mass (not depth, which is why frozen LE - or mass - is the key number for snow removal) for plowing/shoveling.
The surface area to volume/mass ratio is also why large lakes melt much more slowly than small ponds (and part of why the polar ice caps don't melt), if one assumes the same depth of ice to start - since melting occurs mostly from contact with the >32F water on the bottom and sides of the slab (since most of the ice is submerged), the amount of relative surface area available for melting from the sides is much greater for a small slab than a large slab (or nearly infinite one like the ice caps).
Not much melting is actually occurring from above the surface, unless the air temp is quite warm, since the heat transfer coefficient (or thermal conductivity, fundamentally) of water is about 25X greater than for air. If you ever need visceral proof of that, try holding your hand in a -10F freezer vs. submerged in a 32F ice-water bath (like fishing for a beer in the cooler filled with ice water) - you can hold your hand far longer in the -10F air. Chem E 101, lol.
Snowing very lightly here in Metuchen, but no accumulation yet. Decent, but narrow band aimed at my area, which looks like it could put down a coating (1/4" or so). Some decent snowfall going on south of 195/276 in NJ/PA right now.
Edit - we now officially have a dusting...

Had about ~2 inches to shovel on my driveway this morning. Still snowing, so by the time I drove to work I had another 0.25 inch or so.
Hoping it turns to rain so it will melt, otherwise will have to shovel again when I get home.
Hoping it turns to rain so it will melt, otherwise will have to shovel again when I get home.
Ended up with 1/4". S of 195/276 1-2" amounts being reported, especially S of Philly to Toms River. For those locations, part 1 may be more than part 2 tomorrow.
Some useful snow forecast maps. First one is from the Eastern Region NWS, second one is from the NWS-NYC and it is a bit snowier than the Eastern Region map for the NW half of NNJ. Both have a general 3-4/4-6" amounts along the 95 corridor from Philly to NYC, which is a bump up from earlier (3-4" near the TPK and 4-6" near Rt 1). Third map is from The Weather Channel, who also increased snowfall forecasts for
The 18Z runs of the GFS, GFS-FV3, NAM and Euro look reasonably close to what they were before - some fluctuations, but not all in any direction to detect any significant changes in what's coming, so I'm not posting them (twice a day is more than enough). However, here are some good maps from various sources.
The first one from the NWS Eastern Region is great for seeing the big picture from the NWS...although it seems to be a bit at odds with the 2nd map from NWS-NYC, especially for the NW half of NNJ (a bit more in the NYC graphic), below. These also appear to not include the snow from "storm" 1, as amounts S of 276/195 are low. I included that below, also, as well as the NWS-NYC map, which bumped up totals from this morning. Still haven't seen a map from NWS-Philly for storm 2, but the fact that these other maps are out there must mean they're in agreement. In addition, I included an updated map from TWC, which bumped totals up a bit again, but it's not that far off from the NWS maps (a little higher).
Will be interesting to see if these maps verify or not. With mixed precip events, featuring a significant warm layer aloft moving in over time and cold air damming trying to keep the cold air from the high in eastern Canada in place, bust potential on either side is pretty high. If that warm layer arrives a few hours later, a 3" of snow + 1" of sleet forecast could easily become a 6" of snow + 1" of sleet, whereas if the warm layer arrives a few hours early, that outcome could change to <1" of snow + 1" of sleet. Huge difference in outcomes over something that is quite difficult to predict accurately 1.5 days out or even 6 hours out.
After last night's/this morning's appetizer, the main event for most of us starts before sunrise on Tuesday and uncertainty is still high on when the precip transitions to sleet and then rain and if there is any freezing rain. The GFS/FV3/Euro/CMC all trended a little bit warmer/wetter vs. their earlier runs last night and this morning, while the UK/NAM did not, so snow/sleet forecasts have been trimmed back a little bit (1/2-1" less generally) for most, although this should still be an impactful storm, especially for Tuesday morning's rush hour, which should feature plenty of snow/sleet. The pm rush could also be icy for the 95 corridor N of Trenton, if the transition to rain is delayed and will be icy N/W of 95 and especially N of 78 (and W of 287), where the transition to rain isn't likely until early evening. NWS has advisories up for all of NJ and eastern PA and NYC metro/LI.
- For the 95 corridor from Trenton to NYC, they're predicting 2-4" of snow and sleet with the transition to sleet likely in the mid/late morning and to rain by early/mid-afternoon with 0.5-0.75" of plain rain likely through Tuesday night.
- For the Lehigh Valley, Upper Montco/Bucks, Warren/Morris, Passaic, Bergen, and the Hudson Valley, they're predicting 3-5" of sleet/snow, with the transition times a few hours later than for I-95, i.e, early evening to all rain and maybe only 0.5" of plain rain.
- For counties S of 276/195, they're generally predicting 1-3" of snow/sleet with an earlier transition to sleet (then up to 1" of rain) vs. the 95 corridor from Trenton to NYC.
- For the immediate coast S of Toms River and S of a Dover, DE to AC line, <1" snow/sleet is expected; for these locations last night's snow will likely be more than Tuesday's.
- And Sussex, the Poconos, Orange and W. Passaic are under watches for 6"+ of snow/sleet with probably <1/4" of plain rain, if any in spots.
- And freezing rain is a risk for everyone, but especially NW of the 95 corridor where up to 0.1" is possible. Maps are below.
- Lastly, there is a decent chance that half to most of the snow shown on the maps will end up being sleet. It’s not as pretty as snow and, for example, 2” of sleet doesn’t “sound” as bad as 6.6” of snow (they’re equivalent in mass, as both are 0.66” of frozen liquid), but both have the same impact for shoveling, plowing and driving (frozen mass is the key). In addition, due to sleet’s much lower surface area to volume ratio, it will melt much more slowly than snowflakes on roads or from indirect sunlight

Yeah the models seemed to cut back on snow totals a bit. Its still going to be an impactfull storm because of the timing. Today is about fine tuning the forecast and start times but with mixed precip events timing of changeover is crucial
Hey @DJ Spanky - might want to tune into TWC - they keep playing your favorite song in honor of V-Day. Lovin' You, by Minnie Riperton...
This morning was just a glorified dusting, no delays whatsoever. Roads are fine.
Looking at the roads, they are all clear. It doesn't look like it salted last night.
FYI - WW is setting up tonight as a snow bust, mostly slop:
The second storm tonight will be much more difficult to handle from an operational standpoint. First, the start-time is tricky because dry air from the NE will keep trying to cut off the initial precip. While the risk for light snow begins as early as 12 AM, it is much more likely 4-7 AM. Thereafter, it rapidly gets steady and any snow is probably brief as we go to sleet.
Most of the predicted total is likely sleet and that is a good amount as more than a coating of sleet is dense and difficult to remove. Then it's over to rain late morning / early afternoon. Some spots are around 32 during that point, so rain can freeze on contact and lead to ice. We expect to warm slightly later in the daytime and that ends the ice threat going into Tuesday Night. The exception, could be places further from Route 1 (Pennington, Hillsborough) as they may hang onto ice until early evening.
Snow/sleet = 0.5 to 2.0 (60% likelihood).
Sleet is much worse than snow because its such a bear to remove. Hopefully we just have a brief transition period before it goes to plain rain
I gave you props in the Hackenberg thread- you had him pretty well nailed down to fail as an NFL QB when he was still in college. Solid prediction.
How's the ocean-churned up?
Our driveway and front walkway covered. Glad I scraped the driveway and walkway, as everything is now melting away. Just measured, and have exactly 1" of snow in the back yard. Still snowing.
The NWS also had a superb discussion this morning, below, as are the usual links to the NWS and the discussion threads on the 33andrain and AmericanWx message boards, if interested. Loved the honesty of the NWS forecaster in saying what's in bold below.

SHORT TERM /6 PM THIS EVENING THROUGH TUESDAY NIGHT/...
This is one of the most complicated forecasts of my admittedly
short career, largely owing to logistics, but lack of physical
understanding regarding what will transpire tonight through
tomorrow night is not far behind. We start with
watch/warning/advisory decisions this morning:
(1) Based on collaboration with CTP, BGM, and OKX, we will
continue the winter storm watch as is for Sussex (NJ), Carbon,
and Monroe Counties. This is based on remaining uncertainty with
snow and ice amounts Tuesday and Tuesday night.
(2) Berks, western Montgomery, upper Bucks, and Lehigh Counties
will be in a winter weather advisory from this evening through
early Tuesday evening based on expected onset of wintry
precipitation tonight and transition to mostly rain by Tuesday
evening.
(3) Hunterdon, Somerset, Middlesex, Monmouth, and Mercer
Counties will be in a winter weather advisory from midnight
tonight to early Tuesday evening.
(4) Northampton, Warren, and Morris Counties will be in a winter
weather advisory from midnight tonight to 1 am Wednesday.
(2)-(4) are based on the general onset timing and precipitation
transition of the latest NAM, NAM Nest, and hi-res simulations.
Forecast was based largely on a consensus blend of the coarser
and hi-res 00z/06z models, though additional weight was provided
to the NAM/NAM Nest, owing to its preferred evolution of the
low-level thermal profiles (and its generally good performance
in warm-advection events like the upcoming one).
In general, the overall thinking with precipitation Monday night
through Tuesday night has not changed considerably.
Unfortunately, this means that a large amount of uncertainty
remains, primarily with timing the changeovers from snow to
sleet to freezing rain. The general idea is for snow to spread
northeastward into southeast PA and adjacent portions of
southern New Jersey during the evening, followed by central
portions of New Jersey and eastern PA by or after midnight. As
strong advection continues during this period, a warm nose will
increasingly lead to a transition to sleet and/or freezing rain.
This looks to mainly occur late tonight and Tuesday morning,
generally near/north of the I-76 corridor (precipitation mostly
rain to the south). Mixed precipitation will spread rapidly
northward during the morning hours, and may linger through at
least early afternoon near and especially west of the
Philadelphia metro area. Eventually, warmer air will surge
sufficiently northward to scour the cold air south of the
I-276/I-195 corridors during the afternoon (at least, that is
what is forecast), but the cold air may prove to stick around
much of the day in the Lehigh Valley and northern New Jersey.
There are two main uncertainties to address, should the timing
above be in the ballpark. (1) How much of the precipitation
occurs as snow versus sleet versus freezing rain? (2) Are the
models handling the lingering surface cold air adequately? My
inclination is that snow accumulations may be hindered by
residual dry air from a stubborn surface high to the
north/northeast. However, once the precipitation gets going,
large-scale lift will be strong, so the snow may become moderate
to heavy at times before transition to a mix. The sleet signal
may also be overdone given the strength of the warm advection
aloft. The warm nose may become quite pronounced, especially if
cold air damming is as strong as (say) the NAM suggests. This
certainly makes me worry about icing potential, especially in
the far north (generally near and north of I-80). Though
considerable uncertainty remains with relative amounts of each
precipitation type, the combined effects of snow, sleet, and
freezing rain may be sufficient to produce warning-like impacts
despite no individual type meeting warning criteria. As such,
the winter storm watch remains in effect and it is possible
adjoining counties may be upgraded from the current advisory to
a warning in later forecasts.
Another concern is heavy rain in central/southern portions of
the CWA, though models have trended somewhat downward in this
regard. Some instances of flooding may occur, but this is a
secondary concern to the winter weather potential.
Precipitation winds down quickly Tuesday night as the associated
low(s) move northeastward. Lingering snow showers may continue
in the Poconos and vicinity through or past daybreak Wednesday.

Quiet, can't hear any crashing waves. I have a nasty little cold so I'm staying in. Big baby lol.
A least there will be some golf to watch. Even if it's just 2 holes.
written by a newbie...trial by fire for him I guess because this one isnt easy...but unlike some of the other writeups....he lays it out in detailed language and scenerios and by region, I think some of the older guys who do the discos do not bother to go into the needed detail
Yep and I also really liked how he organized things better. Tough one. 12Z NAM/GFS trended back colder/whiter than 0Z/6Z, so it doesn't look like the overall move warmer/wetter last night and this morning was a part of a larger move to much warmer/wetter, like we saw in the 24-48 hours leading up to the last 2 events which turned out to be non-events for the 95 corridor.
The graphic below does a nice job of illustrating how difficult this forecast is - it's for Newark, but the general comments apply for most of CNJ/NNJ, especially near 95. Even just 18-24 hours before the start of the event, the GFS, NAM, and high res NAM (3 km) are nothing at all like each other.
GFS has 0.5" liquid equivalent (LE) as snow (5") and then a simple transition to rain with 1.1" rain, while the NAM-12km is mostly sleet, with 0.8" LE as sleet, 0.15" LE as freezing rain (nasty stuff), and only 0.2" rain. The 3km NAM is roughly 50-50 sleet and rain (about 0.4-0.5" LE of each), with only 0.05" LE as snow (1/2") and 0.1" of freezing rain. And this is without looking at the UK, Euro, CMC and other high res mesoscale models, like the HRRR, which come more into play close to an event. Like I said earlier, high bust potential on either side of the forecast.

the NAM was not really whiter....it was almost all sleet after a brief period of snow..its looking like that dry air is delaying the precip from moving to far to the north and east. Looks like the main thrust is shifting a little later. Im not expecting a lot of snow at all tomorrow.
