I don't think it's worth a new thread, yet, but keep your eye on a potential rain to snow event Christmas morning (not much snow expected in the I-95 corridor, but could be some well to the N/W). It then looks to get quite cold from about the 26th through at least the first few days of January, with multiple chances for snow (12/28, in particular looks juicy, but it's still 8 days away, so way, way too early to speculate about).
The cold is pretty much a lock; snow, as always, is a bit of a crapshoot, but like I said in the first post in this thread, it's more likely than normal to snow in a cold pattern: and the recent pattern certainly delivered, with 5-10" of snow, so far, in December (9.3" in beautiful Metuchen) for most of the Philly-NYC region vs. 4-5" normal snowfall for the entire month of December for most.
So, most of this week will remain normal to warmer than normal through Sunday (Christmas Eve), with some rain likely from Friday night through Sat night, with Sat highs making a run at 60F. But then it gets interesting. The last several model cycles have seen the forecast get colder and colder for Sunday/Monday and beyond.
Now we're within 5 days of Christmas and it's looking like we may see a coastal storm develop Sunday night into Monday, likely bringing mostly rain to the I-95 corridor, possibly ending as some snow Christmas morning, with little accumulation, as it looks now. However, it's possible this rain will change to snow earlier to the NW of I-95 with perhaps a small accumulation and maybe even a few inches of snow well N/W. And it's possible the storm is suppressed to our south, also. Too early to tell. Only sure thing is that if it snows on Christmas while we're in Florida, you'll hear my screams of anguish in Jersey.
