The National Weather Service has issued an Ice Storm Warning for Hardin County in Illinois and Crittenden, Caldwell, Daviess, Union, Henderson, Hancock, Webster, Hopkins, McLean, Muhlenberg and Ohio Counties in Kentucky. Perry County in Indiana is under a Winter Storm Warning. Those warnings will be in effect though Thursday at 6PM - additionally, the rest of the Tri-State will remain under a Winter Weather Advisory for the same period.
If you do not have to travel or be on the roads for the remainder of the day, do not leave your house - travel is very dangerous (especially side roads, parking lots, and sidewalks). Most of our communities along the Ohio River and south experienced freezing rain overnight, while areas north of I-64 received mainly snow. This winter weather event caused hazardous driving conditions and several road accidents.
Current model data suggests scattered freezing rain, sleet and snow will return for the afternoon and evening. Snowfall is expected to stay north of the Ohio River, while the freezing rain will stay near Evansville and south of the Ohio. Heavier amounts of icing will pick up through the late afternoon into tonight (biggest threat looks to be overnight). Models are showing the system shifting to the south as we head into the evening hours, which would put our Kentuckian counties at the greatest risk of icy conditions tonight into tomorrow morning. With that being said, you should still be cautious no matter where you live in the Tri-State!
By the time the winter weather exits the region tomorrow morning, most of our Kentuckian communities will have received between 0.1" and 0.3" of ice. Some communities near Madisonville could even measure up to 0.5" of ice. Snow could continue to affect some spots north of the Ohio (portions of Southwestern Indiana and Southeastern Illinois may see up to 1" or 2" of accumulation).
Unfortunately, temperatures aren't helping us out either! Overnight lows will dip into the low 20s, with highs only reaching the upper 20s Thursday afternoon.
