Summary: Time for a thread for a potential snowfall for many, starting Sunday evening and going through about sunrise on Monday. There is the potential for a minor (1-2") to moderate (2-4") snowfall for most of the Philly-NJ-NYC area and this likelihood keeps increasing with each model suite. A whiff or mostly rain is looking unlikely (but still possible) and a significant snowfall (4-8") is unlikely, but now on the table. Even if we do get a few to several inches of snow, with marginal temps (close to or above 32F, especially along/SE of 95) accumulations on treated roads are unlikely (unlike the 1/25 storm where temps were in the teens).
Details: This is probably my last weather post before 6 pm tomorrow (I have an all-day disc golf tourney in the leftover snow in Ft. Washington PA), but figured I'd start the thread, since it seemed like many folks didn't love the 2 threads we had going for the last 2 events and I am capable of learning, lol. The chance of at least a minor (1-2") snowfall is now pretty high with several models (NAM, NAM3km, UK, Euro now showing a general 1-2/1-3" event while the AIGFS, ICON and Weathernext show a 2-4" type event for most N of 276/195 (or even Philly to Toms River and N) up to 78 or 80, so the chance of a moderate (2-4") snowfall is now decent. And even a significant (4-8") storm is no longer a pipe dream, with the GFS showing 6-12" area-wide (the higher amounts south of 276/195 actually) and the AIFS showing a 3-6" event area-wide Also the IBM GRAF model shows a foot of snow, but has also started a hissy fit catfight among some pro mets who think it's been irresponsible to share that output - I don't know anyone who is predicting a major snowstorm or even more than 2-4" without having much better model consensus. Only the Canadian models aren't showing any snow, with precip all south of Philly to AC as rain.
And Lee Goldberg weighed in, changing his forecast from 11:00 to 11:20 pm, probably because he saw the GFS which came out around 10:45 pm, lol. He's now calling for 1-2" for much of the area, as per the map below and noted that this may have to be increased further if ongoing trends continue. Note that most of the models showing snow have marginal temps (maybe 32-34F) for 95 towards the coast, so there may be some initial melting, but snow at night will accumulate more easily especially if there are at least moderate rates and in addition, with marginal temps there will be a rain/snow line likely somewhere south of 276/195 (maybe Philly to Toms River?), which means if the storm moves further north/closer to the coast rain could keep accumulations down into CNJ.
This is a very finicky, complex setup with so many moving parts, making uncertainty very high and meaning a much wider range of solutions are on the table inside of 48 hours from the event than normal, as this truly could be anything from a whiff to a minor event (1-2") to a moderate event (2-4") to even a significant snowstorm (4-8"). Even the curmudgeonly Tomer Burg (one of the best young mets out there) is saying everything is on the table (link below): "Until models get a better handle on this feature gradually over the next 1-2 days, I would be wary of outright dismissing a major (6”+) snowstorm potential, and especially wary of assuming no snow is a guarantee." Stay tuned.
