Heavy lake effect snow showers developed overnight across the snow belt, dumping 1 to 3 inches of snow in some areas. The cold west to northwest flow of air across the area will remain in place today. Instability over Lake Erie is extreme and conditions will continue to favor the development of lake effect precipitation.
Most of the precipitation will fall as snow this morning with a rain/snow mix near the lake shore. An additional 1 to 3 inches of snow could fall across the snow belt, and the National Weather Service has issued a LAKE EFFECT SNOW ADVISORY for these areas.
Outside of the snow belt, a weak disturbance passing through will produce some cloudiness and there will be a few scattered rain and snow showers. High temperatures across the area today will be in the upper 30s to mid 40s.
Lake effect rain and snow showers will transition back to all snow tonight. Winds will shift between west and northwest so the bands will likely move around a bit. Still, some additional accumulations are possible across the snow belt, especially in areas where heavier squalls persist. Outside of the lake effect areas, skies will be partly cloudy with scattered rain or snow showers possible. Overnight lows will dip into the upper 20s to mid 30s.
On Friday, the persistent cold west to northwest flow will continue, gradually becoming more westerly during the afternoon. Occasional snow showers are likely across the snow belt during the morning, mixing with rain during the afternoon. Outside of the snow belt, there is a chance of snow showers early, then skies will become partly sunny. Highs on Friday will reach the upper 30s to mid 40s.
The lake effect activity will finally wind down Friday night, but unsettled weather will likely continue through the weekend as another cold front moves across the state from the northwest.
