An area of low pressure over the Plains States will strengthen as it moves northeastward toward the Great Lakes later today and tonight. Scattered showers are likely across northeastern Ohio today and a few spots could even see a thunderstorm. Temperatures will climb to the mid to upper 50s across the areas.
Warm and moist air will continue to flow northward across the region tonight as the low passes by to our northwest. Late tonight, a strong cold front will move into western Ohio. Showers and thunderstorms will spread across the region late tonight in advance of this system. Lows tonight will fall to the mid 40s early, then gradually rise overnight.
Showers and thunderstorms are likely through Wednesday morning as the cold front moves eastward across the area. Some of the storms could produce locally heavy rainfall. It will become windy as well with wind gusts in excess of 45 mph possible. Temperatures Wednesday morning will climb into the low 60s.
Once the front passes to our east, showers will become a bit more scattered and temperatures will drop sharply Wednesday afternoon. By Wednesday night, enough cold air will be in place to change the rain showers over to snow showers. The snow showers will persist through Wednesday night into Thursday morning as a secondary arctic cold front crosses the region. Lows Wednesday night will fall to the upper 20s.
On Thursday, very cold air will pour across the region. Snow showers will diminish in most areas, by lake effect snow will ramp up across the snow belt areas. Temperatures will hold stead or even fall a couple of degrees during the day. Some snow accumulation will be possible across the snow belt.
The cold weather and lake effect snow showers will persist through Friday and into the upcoming weekend.
