Light rain and sleet continues to spread east across southeast Missouri and into far west Kentucky late this evening. Some snow was mixing in as well across the Ozark foothill region. With temperatures remaining in the mid 30s through midnight...travel problems should be minimal.
Overnight...through early Thursday morning...the best chance of mixed wintry precipitation should be south of a Carbondale Illinois to Calhoun Kentucky line. With temperatures near or just above freezing...accumulations will be minimal most areas. Best chance of accumulating snow up to 1 inch will be from Perryville to Marble Hill and greenvile in southeast Missouri. Main impacts overnight into early Thursday morning will be potential slick spots on bridges...overpasses and secondary or untreated roads.

...A light wintry mix of precipitation is possible late tonight and early Thursday morning...
Incoming precipitation overnight will be light...falling generally as little to no impact rain or light snow.
However...as temperatures cool overnight...some pockets of a wintry mix of light sleet or freezing rain may mix in with precipitation at times...but should have little to no impact on roadways.
The primary effect will be on untreated roadways or elevated surfaces that dip to freezing and have residual moisture on the ground...allowing for isolated slick patches to develop. No widespread hazardous weather is anticipated at this time.
