Just a quick update on where we stand as of mid-day today. Models continue to track a very strong low up the east coast beginning Wednesday evening. As of now, the snow will start in our area during the overnight hours before sunrise Thursday. How significant those impacts are exactly, we still do not know. At minimum I’d say to expect a few inches of snow in Nassau County and West, Suffolk is looking more likely for 6″+. However, there is still a great deal of uncertainty regarding the exact track of the low. In this scenario a tracking difference of 50-75 miles will make a significant difference in snowfall totals. I plan on putting out a first guess tonight for snow totals tonight, with more details tomorrow as hopefully the models and real-time observations lead to more clarity.

1/4/18 Potential Snowstorm
I hate to be the bearer of bad news on this first day of 2018 (ok maybe I enjoy it a bit), but we are potentially in the path of a large storm for Thursday morning/day/night. As of this afternoon, the weather models are in two camps with the Global models portraying a light to moderate event for our region. While the Hi-Resolution “Meso” models, are beginning to hint at a far more significant event. We are currently at the long range end of the Hi-Res models, but in the past they have picked up on some of our bigger events that the global models were not enthused with. I am not yet ready to commit one way or the other at this point in time. There are still a few major wild cards, with the biggest being some energy that is dropping down from the North Pole region that will not be sampled at all for at least another day. The strength and positioning of this energy will make the difference between a small event and a major snowstorm. I’ll continue to provide updates over the next few days.
As a side note, the cold we are experiencing likely will not end until after the weekend. Keep warm everyone.
Here are a few sim radars from the Hi-Res modeling. Note that these models are typically most accurate within 48 hours of an event, but as I said above they often can identify important features that the global models may be missing.
12/9/17 Storm Update
We are still on track for an early winter snowstorm, and as I’m sure many are aware, our region is under either a Winter Weather Advisory or Winter Storm Warning. Snow should begin in the area between 6 and 9 AM. The snow will start light, and probably not stick much initially, but the snow will pick up in intensity throughout the morning into the afternoon. The heaviest snow will be from late morning into the afternoon. Snow will become lighter and slowly taper off on Saturday night. In general you can expect 3-6″ of snow throughout the area. Those in NYC will likely see on the low end and possibly closer to a 1-3 slushy snow type of event. In Suffolk you should expect towards the higher end of the forecast. The RGEM, which typically performs well shows over 6″ in Suffolk, but that may not come to fruition due to some issues in the upper atmosphere where snow forms which may reduce totals. On Sunday, temperatures will rise into the mid to upper 30’s so the snow should begin to melt fairly quickly and not immediately freeze over. However, Sunday night into Monday temperatures will likely drop below freezing so be sure to get outside Sunday and clear away the snow/slush before it freezes over.
Update on December 9th Storm
As of this evening, models are coming into strong agreement that we will see accumulating snowfall region wide starting early Saturday morning. The snow will start light and gradually pick up throughout the day, the snow will end late Saturday night into Sunday morning. There is still some uncertainty with snowfall totals, but it’s safe to say to expect 2-6 inches. With less the further West you go and more to the East. Temperatures throughout the event will remain in the low 30’s right around freezing, and rise to the mid-30’s on Sunday.
Update on Saturday storm
I will post a full update tonight, but at this point I can say with some certainty that we will see accumulating snow on Saturday into Sunday. I will provide details on amounts later, but you can expect at least a few inches by Sunday morning. More to come later.
Is it Coming? Maybe…
As I alluded to yesterday, we have to keep our eyes out for a potential storm this coming weekend. Right now, there is a wide spread on the models regarding the potential for a storm. However, all are showing a storm or two storms forming Friday night or Saturday. The tracks vary with some showing the potential for a few inches of snow to others showing a few flakes in the air. At this point in time, I cannot say what to expect with any certainty outside of cold weather next weekend…More to come during the week.
