THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTH AND CENTRAL GEORGIA.

.DAY ONE...TODAY.

...ISOLATED THUNDERSTORMS AND LOCALLY HEAVY EXPECTED TODAY...

.SYNOPSIS...
A NEARLY STATIONARY BOUNDARY WILL LINGER ACROSS THE AREA THIS
AFTERNOON INTO TONIGHT.  AT THE SAME TIME A DISTURBANCE WILL CROSS
THE AREA THROUGH THIS AFTERNOON.  ONCE THIS DISTURBANCE
PASSES...PRECIPITATION SHOULD DIMINISH LATER THIS AFTERNOON AND EARLY
TONIGHT. THE MAIN WEATHER SYSTEM WILL THEN APPROACH THE AREA LATER
TONIGHT INTO WEDNESDAY.

.PRIMARY HAZARD...THE PRIMARY HAZARD FROM THE ISOLATED THUNDERSTORMS
WILL BE LIGHTNING. HOWEVER...MOST OF THE LIGHTNING IS EXPECTED TO BE
CLOUD-TO-CLOUD AS THE GREATEST INSTABILITY IS IN A LAYER FROM 1000 TO
6000 FEET. IN ADDITION...LOCALLY HEAVY RAIN COULD CAUSE SOME MINOR
FLOODING IN SPOTS.

.DISCUSSION...
A NEARLY STATIONARY BOUNDARY IS SET UP ACROSS MIDDLE
GEORGIA...ASSOCIATED WITH HIGHER DEWPOINTS. THIS BOUNDARY WILL MOVE
LITTLE THROUGH TONIGHT. AS A DISTURBANCE CROSSES GEORGIA THIS
AFTERNOON...SOME ISOLATED THUNDERSTORMS ARE POSSIBLE. HOWEVER...MOST
OF THE LIGHTNING IS EXPECTED TO BE CLOUD-TO-CLOUD AS THE GREATEST
INSTABILITY IS IN A LAYER FROM 1000 TO 6000 FEET. IN THIS LAYER...THE
LIFTED INDEX WILL DROP TO -1 CELSIUS TO -2 CELSIUS. WITH PLENTY OF
MOISTURE THROUGH A DEEP LAYER OF THE ATMOSPHERE...EXPECT LOCALLY
HEAVY RAIN...ESPECIALLY ALONG AND NORTH OF INTERSTATE 20 THROUGH 4
PM. ONCE THIS DISTURBANCE PASSES...PRECIPITATION WILL DIMINISH. THE
NEXT DISTURBANCE WILL APPROACH THE AREA LATE TONIGHT INTO WEDNESDAY.
AT THAT TIME...THERE SHOULD BE ENOUGH INSTABILITY TO THE SURFACE TO
ENHANCE THE CHANCE FOR CLOUD-TO-GROUND LIGHTNING.

.SPOTTER INFORMATION STATEMENT...
SPOTTER ACTIVATION IS NOT ANTICIPATED THROUGH TONIGHT.

.DAY TWO THROUGH DAY SEVEN...WEDNESDAY THROUGH MONDAY.
ISOLATED THUNDERSTORMS AND LOCALLY HEAVY RAIN CAN BE EXPECTED
WEDNESDAY. SOME MINOR FLOODING IS POSSIBLE. OTHERWISE...NO HAZARDOUS
WEATHER IS EXPECTED.
