Low pressure tracking up through the Ohio Valley and western Pennsylvania tonight will bring a wintry mix of precipitation to central New York over the next 24 hours.
Early tonight, the lower atmosphere will be cold enough to support just snow and this will be when most of the accumulating snow will fall in the Syracuse area. At times, there could be some heavier snow. Close to midnight a couple things will happen to impact precipitation across the area. First, the steadiest precipitation will begin to shift east of Syracuse. Second, temperatures aloft will begin to warm and that means snow will start to transition to some sleet or freezing rain. By morning, there could even be some plain rain in and around the Syracuse area. The bottom line is the best chance for accumulating snow in Syracuse will be during the evening where 1-3” of snow is possible. Higher totals are likely east and south of Syracuse.

On Tuesday low pressure will tracks across southeast New York then up into New England. This means our winds will shift into west bringing in colder air. We think our high in the upper 30s will be reached by midday with temperatures dropping in the afternoon. Any mix of precipitation in the morning should go back over to snow or snow showers during the afternoon. The best chance for an additional accumulation of snow Tuesday will be over the Tug Hill where several more inches of snow could fall.
Even colder and cold air will filter in Wednesday night as winds essentially stay out of the west. In fact, temperatures will become more favorable for lake effect will a significant accumulation possible Tuesday night into Wednesday up over the Tug Hill Plateau. Outside this area, you can expect snow showers with just a light accumulation. A gusty breeze will likely put wind chills in the teens. Anything but Spring-like for the first day of Spring.
Low pressure will shift from New England up into eastern Canada where it will reside for the rest of the week. That will bring a chilly northwesterly flow of air to central New York and means a continuation of below normal temperatures along with snow showers. This pattern will remain into the start of the upcoming weekend.
