THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTH AND CENTRAL GEORGIA.

.DAY ONE...TODAY AND TONIGHT
SCATTERED THUNDERSTORMS EXPECTED THIS MORNING AND AGAIN AFTER
MIDNIGHT TONIGHT.
HEAVY RAIN POSSIBLE THIS MORNING AND AGAIN LATE TONIGHT.
STRONG...GUSTY WINDS EXPECTED IN THE HIGHER ELEVATIONS OF FAR
NORTH GEORGIA UNTIL THIS EVENING.

.SYNOPSIS...
A DEEP AREA OF LOW PRESSURE WILL REMAIN IN THE CENTRAL U.S.
THROUGH FRIDAY...THEN MOVE EASTWARD SATURDAY. A SERIES OF STRONG
IMPULSES WILL EMANATE FROM THE MEAN UPPER TROUGH AND TRACK ACROSS
THE EASTERN U.S. THROUGH FRIDAY. A COLD FRONT WILL MOVE INTO NORTH
GEORGIA THIS MORNING AND STALL ACROSS CENTRAL GEORGIA THIS AFTERNOON.

.PRIMARY HAZARDS...
THE PRIMARY HAZARD TODAY WILL BE HEAVY RAIN THROUGH NOON ACROSS
MUCH OF NORTH GEORGIA. THIS WILL LIKELY RESULT IN URBAN
FLOODING...AS WELL AS MINOR FLOODING OF CREEKS AND
STREAMS...ESPECIALLY ACROSS NORTHWEST GEORGIA WHERE MODERATE RAIN
FELL WEDNESDAY NIGHT. SHOWERS AND THUNDERSTORMS WILL SPREAD
NORTHWARD BACK ACROSS THE AREA BEFORE DAYBREAK FRIDAY...RENEWING
THE THREAT FOR HEAVY RAIN ALONG WITH CREEK...STREAM...AND URBAN
FLOODING. OCCASIONAL CLOUD-TO-GROUND LIGHTNING WILL BE POSSIBLE
IN ANY THUNDERSTORMS TODAY AND TONIGHT. FINALLY...SOUTH WINDS OF
20 TO 30 MPH WITH HIGHER GUSTS ARE STILL EXPECTED AT ELEVATIONS
ABOVE 2000 FEET IN FAR NORTH GEORGIA TODAY.

.DISCUSSION...
A DEEP UPPER TROUGH WILL REMAIN IN THE CENTRAL U.S. THROUGH
FRIDAY...THEN SWEEP EASTWARD SATURDAY. A SERIES OF STRONG SHORT
WAVES WILL ROTATE THROUGH THE UPPER TROUGH...BRINGING AT LEAST
THREE ROUNDS OF THUNDERSTORMS TO NORTH AND CENTRAL GEORGIA. THE
FIRST WILL OCCUR THIS MORNING AS AN AREA OF RAIN AND THUNDERSTORMS
MOVES NORTHEAST FROM THE MID-MISSISSIPPI VALLEY. THIS ACTIVITY
WILL BRING RAINFALL OF 1.0 TO 1.5 INCHES ACROSS MUCH OF NORTH
GEORGIA THROUGH NOON...THEN DIMINISH FROM THE WEST. THIS FIRST
ROUND OF ACTIVITY IS EXPECTED TO BE NON-SEVERE AS THE AIR MASS
REMAINS RELATIVELY STABLE ACROSS THE REGION. AFTER MIDNIGHT
TONIGHT...A WARM FRONT WILL LIFT NORTH FROM CENTRAL GEORGIA AS THE
NEXT IN THE SERIES OF UPPER-LEVEL DISTURBANCES MOVES NORTHEAST
FROM THE SOUTH CENTRAL U.S. SCATTERED TO NUMEROUS SHOWERS AND
THUNDERSTORMS ARE EXPECTED BY DAYBREAK FRIDAY ACROSS CENTRAL
GEORGIA...MOVING NORTHWARD DURING THE MORNING. A FEW STRONG TO
SEVERE THUNDERSTORMS ARE POSSIBLE ACROSS CENTRAL GEORGIA EARLY
FRIDAY ALONG THE ADVANCING WARM FRONT WHERE GREATER INSTABILITY
WILL EXIST...BUT AGAIN THE MAIN THREAT WILL BE HEAVY RAIN...WITH AN
ADDITIONAL 1.0 TO 2.0 INCHES POSSIBLE EARLY FRIDAY.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY
THE MID U.S. UPPER TROUGH WILL FINALLY SWEEP EAST LATE FRIDAY INTO
SATURDAY ACCOMPANIED BY A STRONG COLD FRONT. MODERATE TO STRONG
INSTABILITY AND SHEAR SUGGEST THE POTENTIAL FOR A SIGNIFICANT
SEVERE WEATHER OUTBREAK DURING THIS TIME FRAME. ALL FACETS OF
SEVERE WEATHER WILL BE POSSIBLE...INCLUDING TORNADOES. REPEATED
ROUNDS OF HEAVY RAINFALL FROM THURSDAY THROUGH SATURDAY WILL
INCREASE THE POTENTIAL FOR FLOODING AND FLASH FLOODING AS WELL.
THERE WILL BE ANOTHER CHANCE FOR THUNDERSTORMS TUESDAY.
OTHERWISE...HAZARDOUS WEATHER CONDITIONS ARE NOT EXPECTED SUNDAY
THROUGH MONDAY...OR ON WEDNESDAY AS THIS TIME.

.SPOTTER INFORMATION STATEMENT...
SPOTTER ACTIVATION IS NOT ANTICIPATED THROUGH TONIGHT.
HOWEVER...SPOTTERS AND COCO-RAHS OBSERVERS ARE ENCOURAGED TO SEND
HEAVY RAINFALL REPORTS TO THE NATIONAL WEATHER SERVICE. SPOTTERS AND
EMERGENCY MANAGERS SHOULD BE PREPARED FOR ACTIVATION THROUGH AN
EXTENDED PERIOD FROM FRIDAY AFTERNOON THROUGH SATURDAY AFTERNOON
WITH THE POTENTIAL FOR A MAJOR SEVERE WEATHER OUTBREAK DURING THIS
TIME.
