The National Weather Service has issued a Winter Weather Advisory for Richland and Lawrence Counties in Illinois and Knox and Daviess Counties in Indiana in anticipation of our next weather maker late this evening and overnight. A passing core of low pressure will generate periods of scattered rainfall/wintry mixture north of the Ohio beginning around dinnertime before exiting northeast of the region between 2AM and 3AM. While the majority of our Hoosier and Illinois communities will see isolated rainfall at best, cities within the counties named above may see up to 1" of snowfall accumulation.
As the clipper system responsible for our passing winter weather exits east during the predawn hours Tuesday, cloud cover will begin to thin out across the Tri-State. After seeing temperatures dive to 34° tomorrow morning in Evansville, the clearer skies by the afternoon will allow the mercury to reach 43°. Wednesday looks as though it'll be mostly sunny with high temperatures again in the mid to low 40s area-wide - it's Thursday that we'll need to watch closely.
Temperatures Thursday afternoon will surge across the Tri-State; we'll reach 52° in Evansville (coming within just 2° of matching the year's peak temperatures thus far), but a cold front that night will allow a blast of Arctic air to reach into the Ohio Valley and drive the mercury back down in the mid to upper 20s by early Friday. We'll wrap up the work week on a bit of a cool note; after seeing temperatures reach the upper 30s that day, overnight lows will drop into the upper teens and low 20s by early Saturday. If we fall to our current forecast low of 21°, it will mark our coldest temperatures recorded in Evansville since Christmas morning!
