A disturbance is quickly moving across the southern Great Lakes with a round of strong to locally severe thunderstorms. A few of these storms may produce hail up to 1 inch in diameter. Some of these storms are producing also 1-2 inch per hour rainfall rates.
Several spots have seen more than two inches of rain already today, including Peoria, Illinois, which has already seen 5.25 inches. Flooding has been reported in Peoria since early Friday afternoon.
This rainfall will set the stage for flooding overnight. Flash flood watches have been issued from eastern Kansas and northern Missouri to northern Illinois and northwestern Indiana, and include the Kansas City and Chicago metro areas.
This disturbance is expected to move eastward quickly enough for the atmosphere to recover over Iowa, Missouri and Illinois. This recover is expected to allow severe thunderstorms to develop with a new disturbance over the next few hours.
