The National Weather Service has issued an Ice Storm Warning for Hardin County in Illinois and Crittenden, Caldwell, Webster, Hopkins, McLean, Muhlenberg and Ohio Counties in Kentucky. That Warning goes into effect at midnight and will last through Thursday at 6PM - additionally, the rest of the Tri-State will remain under a Winter Weather Advisory for the same period. The aforementioned Warning and Advisory were issued ahead of our next round of winter weather expected to settle in across the region overnight and early tomorrow. By the time you awake Wednesday, it's likely that the whole Tri-State will be receiving freezing rain or drizzle.
After reaching our southwesternmost counties shortly after midnight, the freezing precipitation will have spread to cover the entirety of the Tri-State by 6AM - it's likely that the entire area will continue to see sporadic to sustained freezing rain through at least 9AM or so. If you do not have to travel or be on the roads tomorrow morning, do not venture out- travel is expected to quite treacherous tomorrow morning, especially south of the Ohio River. Current model data suggests that we may see a break from the freezing rain and ice beginning around our lunch hour. That break from the icy action however, will likely be short lived as a resurgence of ice and freezing rain will again push north to the Ohio affecting all of our Kentuckian communities by 5PM Wednesday. From there the ice will continue to pile up south of the Ohio River through at least Thursday morning.
By the time the last of the wintry precipitation exits east of the region Thursday morning or early afternoon, most of our Kentuckian communities will have received between 0.1" and 0.3" of ice. While snow may affect some spots north of the Ohio (portions of Southwestern Indiana and Southeastern Illinois may see up to 1" or 2" of accumulation), the potential for debilitating ice accumulations will have the greatest impact over the next 36 to 48 hours. Untreated roads may become impassable, trees may shed limbs under the weight of the ice and scattered power outages may occur. Storm Team 44 will continue to keep you up to date on the situation as it continues to evolve.
