MOST OF THE CONVECTIVE ACTIVITY OVERNIGHT HAS BEEN FOCUSED NEAR THE SURFACE LOW AND ATTENDANT COLD FRONT. SEVERE WEATHER POTENTIAL AND CONVECTIVE CHANCES REMAIN THE MAIN CHALLENGES IN THIS MORNING/S FORECAST PACKAGE.

ANY THUNDERSTORMS THAT BECOME SEVERE WILL HAVE THE POTENTIAL TO PRODUCE LARGE HAIL AND DAMAGING WINDS. IN ADDITION...PRECIPITABLE WATER VALUES OVER 2 INCHES AND K INDICIES APPROACHING 40 ALSO SUGGEST THE POTENTIAL FOR THUNDERSTORMS TO PRODUCE LOCALIZED FLASH FLOODING FROM HEAVY RAINFALL.
