WINDY WEDNESDAY FOR LONG ISLAND, SNOW IN THE LONG RANGE?

Good morning!

Monday’s storm system refuses to go quietly, with the upper level low still sitting over Maine this morning. It is spinning down some snow showers across upstate New York, and a few flurries have even made it to Long Island this morning. As high pressure attempts to build in from the southwest, a persistent and at times gusty NW wind is expected keep things feeling cold all day. Wind chills this morning are in the 20s, and afternoon wind chills will be in the 30s. Winds may gust up to 40 mph at times. Bundle up before you head out today!


There will be more clouds than sun today but it will be dry, and will stay that way through Friday. It will remain breezy on Thursday but skies will be brighter as high pressure finally wins out. Sun will give way to clouds on Friday and our next weather system will arrive on Friday night, albeit a weak one that will produce only light rain. Saturday during the day will be dry, but rain then returns Saturday night. Yesterday it looked like we may dry out in time to salvage Sunday, but this morning the guidance suggests we will see showers linger into the day on Sunday. There is a positive here, as temperatures soar to near 60°. It will be a short-lived warm up. As skies clear into Monday, temperatures will begin to come back down to earth, eventually becoming unseasonable again by Tuesday. This is where things get interesting.

As I mentioned yesterday. with such cold air in place for the better part of December’s first week, we will need to be on the lookout for any storms. The jet stream will dip just to our southeast which means any storms that form are likely to track very close to Long Island. This morning, the models are latching onto this very solution. The GFS has a storm system right on top of us Wednesday morning, which could bring rain or snow depending on the exact track. Meanwhile, the European has the same idea but with a track that keeps the storm offshore to our south and east. Other models have something similar, but the fact that they are all keying in on SOMETHING means that this situation bears attention in the days ahead.

Have a great day!
