Winter Weather Advisory Issued

A Winter Weather Advisory has been issued by the National Weather Service. The advisory is in effect from 6 PM this evening to 6 AM Wednesday.

A complicated forecast is on tap for the region today and tonight. The latest data has come in a bit more hopeful, suggesting surface temperatures remain above freezing until early in the morning Wednesday.

Let’s take a look at today’s forecast. We’re waking up to temperatures around 32°. Despite northeast flow, we should warm into the mid to upper 30s under mostly cloudy skies through this afternoon.

Rain will begin to move into the region from the south this evening after 4 PM. Temperatures will likely hover just above the freezing during much of the overnight hours. However, if temperatures dip below freezing we could have some major ice problems. The below simulated radar gif is valid from 5 PM to Midnight.

Models have consistently brushed a fine line of freezing rain along the Ohio River. Like I said in yesterday’s forecast, the northeast side of the county will be more prone to icing than the southwest side of the county. It all depends on where the freezing line falls. In the map below, Marshall County is separated between two corridors or freezing rain. Overall, I think 0.1″ – 0.2″ of ice may be possible across portions of the county, but hopefully it’s just a plain, cold rain.

I do believe there will be an eventual transition to freezing rain and sleet by early morning Wednesday. This may lead to the development of a few slick spots on area roadways. Rain will likely wash away salt and brine. Wednesday morning temperatures will be in the upper 20s. Black ice can be very dangerous on the roads and sidewalks.

Chilly Wednesday

The wintry mix should move out of the region by 9 AM. Clouds should begin to depart the region as highs top out in the mid 30s. This will allow for some melting of whatever accumulations we receive.

High pressure will move directly overhead Wednesday night. This will lead to clear and cold conditions as lows drop to around 20°.

Warmer Thursday

Southerly surface flow will return to the region on Thursday. This, combined with mostly sunny skies, will lead to much warmer temperatures. Highs are expected to top out in the mid 40s.

Looking Ahead

Even warmer conditions are expected Friday before another shot of rain and wintry weather move into the region Friday night and into Saturday. More details regarding that will come in later forecasts.

That should wrap up this forecast. Thanks for stopping by and I hope you have a wonderful day!
