High pressure over the area this morning will drift eastward this afternoon. Mid level moisture will increase from the west today as low pressure moves through the Great Lakes, but the lower levels will remain very dry. Clouds will increase today, but precipitation should remain to our north through tonight.
On Wednesday, a weak cold front will move southward across the state. There may be just enough moisture associated with this front to produce some light snow showers Wednesday afternoon through Wednesday night. Any accumulations should be very light.
High pressure will build back across the region on Thursday.
Here is the forecast: For today, mostly cloudy with highs in the low 20s. Winds S 5 mph.
Tonight, mostly cloudy with lows around 10. Winds calm.
Wednesday, mostly cloudy with a chance of snow showers after noon. Highs will be in the mid 20s. Winds N 5-10 mph.
Wednesday night, mostly cloudy with a chance of snow showers. Lows will be in the low teens.
Thursday, partly sunny and not as cold with highs climbing to the low 30s.
Extended Analysis: High pressure will drift eastward across the region Thursday night. Another cold front will sag southward across the Great Lakes Friday, reaching northern Ohio Friday night. This front will not have much moisture with it, however a little light snow is possible Friday night.
Yesterday, models indicated a fairly strong wave of low pressure would develop along the front, but have since backed away from this idea. Instead, models are now showing a flatter wave tracking through the Ohio Valley Saturday and Saturday night. This will allow colder air to filter southward across the region Saturday, with snow possible Saturday and Saturday night. This does not look like a major even at this point, and instead will probably be a nuisance-type snowfall.
The system will pull away to the east Sunday as high pressure builds across the lower lakes.
Here is the extended forecast:
Thursday night - Partly cloudy with lows around 20.
Friday - Mostly sunny with highs in the low 40s.
Friday night - Mostly cloudy. Lows in the mid 20s.
Saturday - Chance of snow. Highs in the mid 30s.
Saturday night - Chance of snow. Lows around 20.
Sunday - Chance of snow during the morning, then mostly cloudy. Highs will reach the low to mid 30s.
