Toward evening, a strong storm system and associated cold front will approach from the Plains. A new round of strong to severe thunderstorms will likely develop in southern Missouri and sweep into northern Arkansas.
This could be a significant severe weather event, and somewhat unusual for August. This kind of event is more reminiscent of spring. Destructive winds and large hail are the main concerns, and an isolated tornado or two are possible.
Torrential downpours are expected in places. The forecast calls for two to three inches of rain in parts of the north, and this may result in localized flash flooding.
