NORTH AND CENTRAL GEORGIA THUNDERSTORM OUTLOOK
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
1230 PM EDT SAT APR 13 1996

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER NORTH AND CENTRAL
GEORGIA THIS AFTERNOON AND EARLY EVENING.

CONSIDERABLE MOISTURE HAS SPREAD INTO THE SOUTHEAST...WELL AHEAD OF A
FRONTAL BOUNDARY NEAR THE MISSISSIPPI RIVER. THE AIRMASS OVER OUR AREA
COULD SUPPORT ISOLATED SEVERE THUNDERSTORMS AS STEADY SOUTHWEST WINDS
COMBINE WITH HIGH MOISTURE AND AFTERNOON HEATING.

LARGE HAIL AND DAMAGING WINDS WOULD POSE THE GREATEST THREAT.

SPOTTER ACTIVATION IS NOT EXPECTED BUT SPOTTERS SHOULD REMAIN ALERT
IN CASE SUPPORT IS NEEDED.
