AN UPPER LEVEL DISTURBANCE MOVING TOWARD THE REGION...WILL COMBINE WITH INCREASING MOISTURE AND INSTABILITY TO PRODUCE SHOWERS AND THUNDERSTORMS ACROSS THE REGION THIS AFTERNOON AND TONIGHT. THE UPPER LEVEL DISTURBANCE WILL BE FOLLOWED BY A COLD FRONT MOVING THROUGH ON FRIDAY.

SO...SOME PULSE MARGINAL SEVERE HAIL AND GUSTY WINDS POSSIBLE THIS AFTERNOON...THEN A LITTLE BIT MORE ORGANIZED AND WIDESPREAD CONVECTION TOWARD SUNSET AND THROUGH THE EVENING.
