THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTH AND CENTRAL GEORGIA.

.DAY ONE...TONIGHT

...ISOLATED SEVERE THUNDERSTORMS POSSIBLE UNTIL MIDNIGHT WEST GEORGIA...
...ISOLATED THUNDERSTORMS POSSIBLE EAST GEORGIA AFTER MIDNIGHT...

.SYNOPSIS...
A STRONG UPPER-LEVEL AND ASSOCIATED SURFACE LOW...LOCATED ACROSS
THE MIDWEST MONDAY EVENING...WILL MOVE NORTHEAST TOWARD THE GREAT
LAKES TONIGHT AND TUESDAY. A COLD FRONT TRAILED FROM THE SURFACE
LOW INTO MISSISSIPPI AND WESTERN TENNESSEE. THE FRONT WILL MOVE
EAST INTO GEORGIA TUESDAY MORNING.

.PRIMARY HAZARD...
THE PRIMARY HAZARD FROM THUNDERSTORMS THIS EVENING WILL BE
DAMAGING STRAIGHT LINE WINDS AND OCCASIONAL CLOUD-TO-GROUND
LIGHTNING. THE GREATEST AREA OF CONCERN WILL BE WEST OF A LINE
FROM DALTON...TO ATLANTA...TO THOMASTON...TO AMERICUS...MAINLY
BEFORE MIDNIGHT.

.DISCUSSION...
THE ATMOSPHERE ACROSS GEORGIA DOES NOT APPEAR TO BE AS FAVORABLE
FOR SEVERE THUNDERSTORMS AS EARLIER EXPECTED. WHILE A STRONG LINE
OF THUNDERSTORMS CONTINUED TO SLOWLY APPROACH THE AREA FROM
ALABAMA THIS EVENING...THE BEST UPPER ATMOSPHERIC DYNAMICS WERE
LIFTING NORTH AWAY FROM THE REGION INTO THE OHIO VALLEY.
MEANWHILE...THE BEST THERMODYNAMICS WERE SINKING SOUTH TOWARD THE
GULF COASTAL REGION. THE STRONG LOW-LEVEL JET WAS LIFTING NORTH
INTO THE OHIO VALLEY. HELICITY VALUES...WHICH EARLIER HAD BEEN IN
THE 400 TO 500 RANGE ACROSS NORTH ALABAMA AND GEORGIA...HAVE
DROPPED INTO THE 200 RANGE. CAPES ARE ONLY IN THE 200 TO 500
RANGE...WHICH IS CONFINED TO THE SOUTHWEST SECTIONS OF THE
STATE...SOUTH OF COLUMBUS. THUS THE THREAT OF TORNADOES APPEARS TO
HAVE GREATLY DIMINISHED. ON THE OTHER HAND...A STRONG LOW-LEVEL
JET OF 40 MPH WILL REMAIN IN PLACE THROUGH THE EVENING AND
OVERNIGHT HOURS ACROSS NORTH AND CENTRAL GEORGIA. THUS...ISOLATED
THUNDERSTORMS DURING THE EVENING MAY PRODUCE DAMAGING STRAIGHT
LINE WINDS ACROSS WEST GEORGIA. AFTER MIDNIGHT...PARAMETERS ARE
EXPECTED TO BECOME EVEN LESS FAVORABLE FOR SEVERE THUNDERSTORMS AS
THE SYSTEM MOVES INTO EAST GEORGIA WHERE A RESIDUAL WEDGE OF COOL
AIR REMAINS IN PLACE. THUS...ONLY ISOLATED NON-SEVERE
THUNDERSTORMS ARE EXPECTED IN EAST GEORGIA AFTER MIDNIGHT.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY
ISOLATED THUNDERSTORMS ARE POSSIBLE IN EAST GEORGIA TUESDAY
MORNING...OTHERWISE HAZARDOUS WEATHER CONDITIONS ARE NOT EXPECTED
THROUGH THE PERIOD.

.SPOTTER INFORMATION STATEMENT...
ISOLATED SPOTTER ACTIVATION IS STILL POSSIBLE UNTIL MIDNIGHT WEST
OF A DALTON...TO ATLANTA...TO AMERICUS LINE.
