A slow moving storm system will bring several rounds of showers and thunderstorms to portions of the Ohio Valley Wednesday into Friday. Flood Watches extend from central Ohio to northeastern Arkansas. The multiple rounds of rainfall will be heavy at times, producing totals of 2″ to 4″. Flood-prone and low-lying areas will be susceptible to flooding. Rises on area creeks, streams, and rivers are expected. Falling leaves may also clog drainage systems and impede the normal course of water runoff.
A cold front will sink slowly to the south and east from the Great Lakes to central Plains. Humidity will push northward from the Gulf of Mexico as dew points climb. The front will temporarily stall over the region Wednesday night into Thursday, bringing widespread waves of heavy rain. The system will lift away by Friday evening and the showers will come to an end.
