TODAY AND TONIGHT: CHANCES FOR THUNDERSTORMS INCREASE ACROSS THE AREA TODAY INTO TONIGHT. THERE IS A SLIGHT RISK FOR SEVERE WEATHER THIS AFTERNOON INTO TONIGHT…WITH LARGE HAIL AND DAMAGING WINDS THE MAIN SEVERE THREATS.

SCATTERED SHOWERS AND A FEW ISOLATE THUNDERSTORMS ARE POSSIBLE LATER THIS MORNING. SEVERE STORMS ARE NOT ANTICIPATED WITH THIS ROUND OF STORMS…BUT MAY BE POSSIBLE LATER THIS AFTERNOON.  A WEAK FRONTAL BOUNDARY WILL SAG SOUTH TODAY AND WILL BE THE  FOCUS FOR THUNDERSTORMS INTO THE EVENING. A QUICK MOVING UPPER  LEVEL DISTURBANCE WILL AID THUNDERSTORM DEVELOPMENT THIS
AFTERNOON. STORMS COULD BECOME SEVERE LATER THIS AFTERNOON WITH DAMAGING WIND AND LARGE HAIL THE PRIMARY HAZARDS. IF CLOUD COVER PERSISTS THROUGHOUT MUCH OF THE AFTERNOON…THIS WILL LIMIT THE INSTABILITY AND SEVERE STORMS WOULD THEN BE LESS LIKELY. ANY SEVERE STORMS SHOULD REMAIN GENERALLY SOUTH OF INTERSTATE 80.
