A spray of lake effect snow showers is falling apart across central New York early this evening. However, the lake effect will return before the end of the night for parts of the region. A weak disturbance in the jet stream winds aloft will approach us from the west and that will turn our winds into the west. The cold air aloft that is already over us will travel the full length of Lake Ontario so after midnight tonight we expect the lake effect snow showers to get better organized east of the lake with several inches possible by daybreak, especially over the Tug Hill plateau.
By tomorrow morning, the aforementioned disturbance will move through the region and we will start to see the most organized areas of lake effect snow drift south. In addition to coming over Lake Ontario, the air will briefly have the benefit of travelling over Georgian Bay and that may help enhance the snow for a time.
Luckily, the lake snows won’t stay over one place for very long. The best bet for snow in the Syracuse area will be around the lunch hour into early afternoon. We are only expecting a couple of inches in Syracuse during tomorrow but the bulk of this snow may come in 2 or 3 hours early in the afternoon. By late afternoon, the lake snow should be southwest of Syracuse over the Finger Lakes and weakening.
Our weather turns out quiet Thursday but another system, a cold front, will approach late in the day. Is this front tries to move through Friday we will be candidates for some more lake effect snow showers.
Starting later in the weekend and especially next week, the seasonably cold air that is over us now will be ready to depart and head back north into Canada. That means we could be in for extended period of above normal temperatures that could last much of next week.
