High pressure will build across the region, bringing fair and dry weather to northern Ohio today and tonight. It will be very cold tonight with temperatures falling well below zero under ideal radiational cooling conditions.
Temperatures will begin to moderate on Tuesday as the high slides to our east and a southerly flow develops. A weak system will pass north of the area bringing us some cloud cover, but it should remain dry.
It will remain mostly cloudy Tuesday night and Wednesday as a weak cold front sags southward through the Great Lakes and toward northern Ohio. Some light snow is possible by late in the day Wednesday as an upper level disturbance approaches from the west.
Here is the forecast: For today, partly cloudy with highs in the mid teens. Winds N 5-10 mph. Wind chills -5 to -15.
Tonight, clear and very cold with lows -4 to -10. Winds calm.
Tuesday, becoming mostly cloudy with highs around 20. Winds light and variable.
Tuesday night, mostly cloudy with lows 5 to 10.
Wednesday, mostly cloudy with a chance of snow showers during the afternoon. Highs will climb to the mid to upper 20s.
Looking ahead: An upper level system will move through the Ohio Valley Wednesday night through Thursday morning as a cold front slides southeastward across the area. Snow is possible Wednesday night, tapering off Thursday morning. Any accumulations should be light as the system will be fighting some very dry low level air. Lows Wednesday night will be around 10 degrees with highs on Thursday in the low 30s.
A rather strong southwesterly flow will develop across the region on Friday, and this will help to boost temperatures into the 40s under partly cloudy skies.
A cold front is forecast to drop southeastward across the region Friday night accompanied by light snow, possibly even a little rain.
A wave of low pressure is expected to develop along the front and track through the Ohio Valley bringing the threat of snow with it on Saturday. Models are all over the place with this system so check back later for updated forecasts. High temperatures on Saturday will be in the 30s.
