SOUTHERN ILLINOIS – The National Weather Service in Paducah continues to monitor the potential for wintry precipitation late this week, specifically Thursday night, Friday and Friday night. If the current forecast holds, this wintry precipitation is likely to have substantial impacts on travel across our region.
During this time, rain is forecast to change to a mix of freezing rain and sleet, then eventually to snow, from west to east across the four state region of southeast Missouri, southern Illinois, southwest Indiana and western Kentucky. The bulk of the precipitation is expected to taper off by late Friday night or early Saturday morning.
While it is still too early to specify exact timing and amounts, a moderate accumulation of snow and sleet appears possible over top a thin layer of ice in much of southern Illinois and southeast Missouri. Meanwhile, more freezing rain is possible in southwest Indiana and western Kentucky, ending in a light accumulation of snow.
Cold arctic air will continue to filter in over the weekend. Highs will be mainly in the 20s both days, with early morning wind chills near zero Sunday morning. The cold air will persist into early next week, so any snow and ice is likely to stick around for some time.
Keep in touch with the latest forecasts as the weather service narrows down the time frame for accumulating precipitation, further refines precipitation types, and gains a better idea on overall ice and snow accumulation totals.Tweet
