Low pressure will move eastward through the eastern Great Lakes today. Most of the wintry precipitation from overnight has now changed over to rain showers. Scattered showers will continue through this afternoon as moist, mild air continues to stream northeastward across the area. High temperatures this afternoon will climb to the mid 40s.
Tonight, another area of low pressure will move from the Plains State to the western Great Lakes. Showers will continue across the area in advance of this system. Overnight lows will only fall to the low 40s.
On Tuesday, low pressure to our northwest will deepen, pulling even milder air northward across the area. It will be quite warm on Tuesday with mostly cloudy skies and the threat of showers. Highs will reach the mid to upper 50s.
Tuesday night, an arctic cold front will approach from the west late. It will be mostly cloudy, breezy and mild with a chance of showers. Temperatures will fall to the mid 40s during the evening, then rise to the 50s overnight.
Wednesday will be breezy and warm with showers likely during the morning. Around mid day, the arctic front will reach the area with gusty winds, heavy rain, and the threat of a few thunderstorms. Temperatures will surge to around 60 degrees during the morning ahead of the front.
It will turn sharply colder Wednesday afternoon as the front moves to our east and colder air pours southeastward across the region.
Lingering rain showers will change to snow showers by Wednesday evening with lake effect snow showers possible through the day on Thursday. Highs on Thursday will only reach the mid to upper 20s.
