A cold front moving through the central Great Lakes this afternoon will cross the eastern lakes this evening. Widespread rain showers are likely as this feature crosses the area. A mild southerly flow ahead of the front will keep temperatures well above normal today.
In addition to the rain fall, is will be quite breezy today as well with some locations experiencing wind gusts in excess of 35 mph.
Behind the front, colder air will overspread the region tonight with rain showers gradually transitioning to snow showers from west to east. The activity will become scattered overnight so little, if any, accumulations are expected.
A broad, cold west-northwesterly flow will become established across the area on Tuesday with lots of cloud cover and scattered areas of rain and snow showers.
Tuesday night, a secondary cold front will cross the area as a trough digs into the northeastern United States. This system will usher in even colder air. As the colder air spreads across the lakes, conditions will become favorable for lake effect snow, especially from late Tuesday night through the day on Wednesday.
While most locations have the chance of seeing some snow shower activity, the best chance of accumulating snow will be across northeastern Ohio, northwestern Pennsylvania, and western New York in the traditional snow belts. Here, a few locations could pick up several inches of snow by Wednesday evening.
The lake snows will gradually wind down on Thursday as high pressure builds back across the eastern lakes.
