Potential for severe weather this afternoon

 WEATHER HAZARDS EXPECTED...    A SLIGHT RISK FOR STRONG TO SEVERE THUNDERSTORMS CAPABLE OF   PRODUCING HAIL TO THE SIZE OF GOLF BALLS...WIND GUSTS OVER 70 MPH   AND ISOLATED TORNADOES. FLOODING WILL ALSO BE POSSIBLE.    AREAS AFFECTED AND TIMING...    STRONG TO SEVERE THUNDERSTORM AREA AND TIMING...ALONG AND WEST   OF A LINE FROM OSCEOLA TO SPRINGFIELD TO GAINESVILLE BETWEEN   3 PM AND 9 PM.    FLOODING TIMING...LATE THIS AFTERNOON WEST OF HIGHWAY 65 AND   OVER THE ENTIRE OUTLOOK AREA TONIGHT.    DISCUSSION...    A STRONG LOW PRESSURE SYSTEM OVER SOUTH CENTRAL KANSAS AND NORTH   CENTRAL OKLAHOMA EARLY THIS AFTERNOON WILL MOVE EASTWARD INTO   THE OZARKS TONIGHT. WHILE THERE IS VERY STRONG VERTICAL WIND   SHEAR AND INCREASING INSTABILITY AHEAD OF THIS SYSTEM THIS   AFTERNOON...THERE IS CURRENTLY VERY LIMITED LOW LEVEL MOISTURE   OVER THE REGION. IF LOW LEVEL MOISTURE INCREASES SUFFICIENTLY   BEFORE THE STORM SYSTEM ARRIVES...THE STORMS WILL HAVE AN   INCREASING CHANCE OF BECOMING SEVERE.    THE POTENTIAL FOR SEVERE THUNDERSTORMS WILL DIMINISH THROUGH THE   MID AND LATE EVENING HOURS AS INSTABILITY DECREASES.   HOWEVER...MODERATE TO LOCALLY HEAVY RAINFALL MAY DEVELOP ACROSS   THE AREA. THIS RAINFALL COULD LEAD TO LOCALIZED FLOODING AS SOILS   REMAIN SATURATED FROM RAINFALL EARLIER THIS WEEK. A FLOOD WATCH   REMAINS IN EFFECT FOR THE ENTIRE OUTLOOK AREA INTO SUNDAY   MORNING.
