This is forecast to be a very dynamic and rapidly intensifying system which could yield both an enhanced damaging wind threat and a risk of a few tornadoes. Based on current forecasts, the main time period of concern is Wednesday afternoon – mainly southeast Missouri and southwest Illinois – and Wednesday evening, generally along and east of the Mississippi River.
In addition, NWS is forecasting strong gradient winds averaging close to 20 mph Wednesday and Wednesday night with gusts at or above 30 mph.
