Widespread moisture to sweep from southern Plains through the Corn Belt
A storm system over the Southwest will gather moisture and intensify while crossing the southern Plains on Wednesday night. By Thursday, the storm will race northeastward across the mid-South and lower Midwest, delivering a variety of precipitation types. For example, significant snow should fall on Thursday from eastern Kansas into southern Michigan, while mixed precipitation—including freezing rain—may occur from northern Oklahoma to near Lake Erie.
Storm-total precipitation could reach 1 to 2 inches or more from the southeastern Plains into the Ohio Valley and lower Great Lakes region; any flooding could be enhanced where snow remains on the ground from earlier storms or soils are frozen.
Finally, thunderstorms along the storm’s trailing cold front could become severe, with high winds, large hail, and isolated tornadoes possible from the southern Plains to the southern Appalachians, starting tonight and ending early Friday.
In the storm’s wake, cool but mostly dry weather will cover much of the central and eastern U.S. for a few days. During the weekend, a new storm system arriving in the Northwest should deliver unsettled, showery weather.
