THIS AFTERNOON AND COMBINED WITH AN UPPER LEVEL DISTURBANCE HAS
ALLOWED SCATTERED THUNDERSTORMS TO DEVELOP. THUNDERSTORMS ARE

DAMAGING WIND GUST OR TWO CANNOT BE RULED OUT.

ANOTHER ROUND OF THUNDERSTORMS...POSSIBLY SEVERE...IS LIKELY
WEDNESDAY MORNING. WHILE A SEVERE THREAT EXISTS ACROSS THE ENTIRE
