SCATTERED THUNDERSTORMS ARE EXPECTED TODAY AND THIS EVENING ACROSS THE ENTIRE FOUR-STATE REGION INCLUDING SOUTHEAST MISSOURI...SOUTHERN ILLINOIS...WEST KENTUCKY AND SOUTHWEST INDIANA. THERE IS A SLIGHT RISK SOME OF THESE STORMS COULD BECOME SEVERE ACROSS SOUTHEAST MISSOURI...FAR WEST KENTUCKY WEST OF THE LAKES REGION...AND EXTREME SOUTHERN ILLINOIS. A SURFACE LOW PRESSURE SYSTEM AND ASSOCIATED UPPER DISTURBANCE OVER NORTHERN MISSOURI WILL MOVE SOUTHEAST INTO THE BOOTHEEL AREA BY SUNSET. WINDS AHEAD OF THE LOW WILL PULL MORE MOISTURE INTO THE REGION. THESE FACTORS...COMBINED WITH DAYTIME HEATING...WILL ACT TO DESTABILIZE THE ATMOSPHERE THIS AFTERNOON SETTING THE STAGE FOR THUNDERSTORMS. ALTHOUGH LOW LEVEL MOISTURE IS EXPECTED TO INCREASE THIS AFTERNOON ...IT WILL ONLY BE A SLIGHT INCREASE AND THIS COULD BE A LIMITING FACTOR. THERE WILL BE MODERATE UPWARD MOTION PRODUCED BY THE UPPER DISTURBANCE. ATMOSPHERIC WIND SHEAR WILL BE RELATIVELY WEAK. THE MAIN THREAT WITH ANY STORMS WILL BE STRONG GUSTY WINDS AND LARGE HAIL. STORMS THAT DEVELOP OVER SOUTHEAST MISSOURI AND WEST KENTUCKY ARE EXPECTED TO MOVE TOWARD THE SOUTHEAST AT 20 TO 25 MPH. STORMS OVER SOUTHERN ILLINOIS AND SOUTHWEST INDIANA WILL MOVE TOWARD THE EAST AROUND 10 MPH. SPOTTER ACTIVATION MAY BE REQUIRED LATER TODAY OR TONIGHT. SDB
