THE STORM PREDICTION CENTER IS FORECASTING A SLIGHT RISK FOR SEVERE STORMS OVER MUCH OF THE OUTLOOK AREA TODAY AND TONIGHT.

AS THIS OCCURS...IT WILL BE VERY HOT AND HUMID ALONG AND SOUTH OF THE FRONT...WITH HEAT INDEX READINGS AROUND 95 DEGREES IN SOUTHEAST IOWA...WEST CENTRAL ILLINOIS AND NORTHEAST MISSOURI. THIS HOT WEATHER MAY FUEL ISOLATED INTENSE THUNDERSTORMS THIS AFTERNOON IN EASTERN IOWA AND NORTHWEST ILLINOIS. THE PRIMARY THREAT FROM THESE POSSIBLE SUPERCELL THUNDERSTORMS WILL BE VERY LARGE HAIL....POSSIBLY THE SIZE OF TENNIS BALLS. A LAYER OF WARM AIR ALOFT MAY PREVENT THESE STORMS FORM FORMING...BUT THIS THREAT WILL BE NEED TO BE CLOSELY MONITORED TODAY. LATER TONIGHT...A LARGER CLUSTER OF STORMS IS EXPECTED TO FORM IN NORTHERN OR NORTHWEST IOWA...AND WILL MOVE EAST TO SOUTHEAST INTO THE OUTLOOK AREA. THIS CLUSTER OF STORMS MAY BRING THE THREAT OF STRONG WINDS IN EXCESS OF 50 MPH...AND HEAVY RAINFALL. THE AREA MOST AT RISK FOR THESE LATE NIGHT STORMS IS NORTH OF INTERSTATE 80 IN IOWA AND ILLINOIS.
