Very heavy thunderstorms with isolated severe wind gusts will continue early this morning across southeast MO, far southern IL, and western KY. This activity extends along a frontal boundary that extended W to E just north of the KY/TN and MO/AR border. With PWAT values of 2.0-2.3" and training storms, the threat for flash flooding will continue through daybreak.
Showers and thunderstorms will wind down later this morning has the front shift south of the region, and dry weather is expected from this afternoon through Friday. With broad troughing over the eastern CONUS, temperatures will remain near to slightly below normal. Another front will approach the area Saturday and stall just north of the area through early next week. This will be enough to bring small 15-25% shower and storm chances each day Saturday into early next week. Temperatures will remain around normal values for late August.
