With the cold front to our east, a return to more typical December weather is on tap, even if only for a day or two. Brisk northwest winds will import colder air into the region and allow for falling temperatures. Additionally, the cold air moving over Lake Ontario will induce some limited lake effect snow showers. Our window for lake effect snow showers will be rather brief; therefore, any accumulation will be light.
By early tomorrow morning, high pressure should be centered right over Central New York. Consequently, clouds will thin tonight and set the stage for a chilly, but dry Thursday morning. This will also mean a rather quiet day Thursday with sun fading behind increasing afternoon high clouds.
Moisture trying to return Thursday night is part of the aforementioned frontal boundary that will start impact us Friday with rain showers. This front will approach from the west but will get ‘hung up’ here in the Northeast. Jet stream winds aloft will be out of the southwest over us this weekend so the front won’t be too far away from us Saturday and Sunday. That’s why we are keeping showers in the forecast for the weekend.
There is still some uncertainty for early next week but it is looking more and more like a stronger area of low pressure will forma long the front and track to our west on Monday. That will turn our winds back into the south and push our temperatures above normal. A return to colder weather may arrive by Tuesday.
