Flooding Possible This Weekend From The Plains To The Great Lakes

28 Apr 2017, 4:28 pm

The threat for flooding continues to increase for the mid section of the nation tonight into this weekend. Flash Flood Watches now extend from near Lake Michigan to the Red River of the South. Heavy rain will increase with a developing storm system, bringing in the flooding risk.

The heaviest rainfall totals will be in a path close to the track of a low pressure center. 6″ to 9″ of rain is possible by Monday morning. A wide area of 3″ to 6″ rainfall amounts are likely from the Gulf of Mexico to the Great Lakes.

The flooding potential tonight stretches from Eastern Oklahoma to the Ohio River. Thunderstorms, some severe, are expected to develop near a warm front later tonight. Storms pushing northward from the Red River of the South into Oklahoma, Northern Arkansas and Southern Missouri have the best chance to produce flooding.

On Saturday, a low pressure center will lift northward from near Dallas in the morning to around St. Louis by evening. Thunderstorms will produce very heavy rain from the Mississippi River to the Arklatex. The flooding potential is highest in Southwest Missouri and Northwest Arkansas.

As the low lifts northward into the Ohio Valley and Great Lakes Sunday, thunderstorms will spread to the north and east. The widespread flooding risk is slight, but heavy rain falling on over-saturated soils and along high rivers could create additional flooding.
