FORECAST DISCUSSION:

This week’s weather will be a roller coaster. A weak ridge of high pressure will deliver one more day of sunshine with cumulus clouds again this afternoon. It will be seasonably warm with highs in the mid-upper 60s.

Meanwhile a cold front is lurking northwest of Ohio. That front will move southeast through the state tonight. Cooler air comes with it and the low will be near 40 tonight.

Low pressure will develop on that front southwest of the state. That will lift the northern branch back into southeastern Ohio to near the I-71 corridor as a warm front. Tomorrow will be cloudier but the high will again be in the mid-upper 60s.

Next the Big Chill is coming. Cold air from the northwest will move into the region tomorrow night. Precipitation along the frontal boundary draped across the state will start as rain, but it will mix with and change to snow showers as the front dives southeast. There will snow showers and flurries for rush hour Wednesday. The precipitation will change to a mix of rain and snow and then rain showers during the day.

Though the ground is pretty warm the snowfall rate may be quick enough for a slushy inch of accumulations on grassy and elevated surfaces just north of I-70 and northwest of I-71 by daybreak. Higher accumulations, as much as 3 inches, will be possible farther north and northwest. Morning temperatures will be at or below freezing in spots mainly northwest of I-71. Wednesday’s high will be around 40.

Thursday will be the coldest morning this week. Under partly cloudy to clear skies lows will be in the upper 20s to around 30. Highs will be near 50. Temperatures will be milder Friday and into the weekend.

I hope you are having a good Monday.
