Strengthening low pressure will move from the central Plains today toward the Great Lakes by tonight. Mild air and deep moisture will continue to stream northward across the region today. Scattered showers will be possible today, and there could even be a thunderstorm late in the day, especially across the west. Highs will climb to the mid to upper 50s.
The low will pass by to our west tonight. A strong cold front trailing the storm will sweep eastward through the Mid West toward western Ohio by daybreak Wednesday. Showers and thunderstorms will become more widespread across northeastern Ohio after midnight tonight in advance of this front. It will become breezy as well. Lows tonight will fall to the mid 40s early, then rise to the 50s overnight.
The strong cold front will move across northeastern Ohio Wednesday morning. Showers and thunderstorms, some with strong winds and very heavy rainfall will move through during the morning and mid day hours. Highs early in the day will top out around 60 degrees.
Once the front moves east of the area Wednesday afternoon, showers will become more scattered and temperatures will drop sharply. It will remain windy through Wednesday afternoon with gusts in excess of 45 mph possible.
Rain showers will change to snow showers Wednesday evening as the colder air spreads across the area. Residual moisture will combine with a secondary arctic front to provide widespread snow showers to the area late Wednesday night into Thursday morning. Accumulations should be light. Lows Wednesday night will fall to the mid to upper 20s and hold mainly steady through the day on Thursday.
By Thursday afternoon, the snow showers will transition to pure lake effect, becoming more confined to the snow belt areas east of Cleveland. The lake effect snow showers will continue through Friday and into the upcoming weekend with significant accumulations possible across the snow belt.
