..MORNING AREA FORECAST DISCUSSION
KEY MESSAGES
- WARM TEMPERATURES CONTINUE THROUGH THE WORK WEEK WITH HIGHS IN
THE UPPER 80S TO LOW 90S.
- INCREASED RAIN CHANCES RETURN TOMORROW THROUGH THE WEEKEND,
ESPECIALLY IN NORTHERN AND WESTERN GEORGIA.
SHORT TERM
(TODAY THROUGH WEDNESDAY)
ISSUED AT 455 AM EDT TUE MAY 19 2026
TEMPERATURES WILL QUICKLY CLIMB INTO THE UPPER 80S AND LOW 90S THIS
AFTERNOON, WITH RELATIVE HUMIDITY FALLING INTO THE UPPER 30% RANGE
AS HIGH PRESSURE KEEPS MOISTURE OFF TO THE WEST OF THE CWA. THIS
WILL PREVENT AFTERNOON THUNDERSTORMS FOR A FINAL DAY BEFORE WE
REINTRODUCE THEM TO THE FORECAST TOMORROW. WINDS WILL BE LIGHT OUT
OF THE S/SE AT LESS THAN 10MPH.
OVERNIGHT LOWS WILL REMAIN IN THE 60S AND MOISTURE VALUES ACROSS NW
GEORGIA WILL INCREASE OUT AHEAD OF A COLD FRONT PUSHING THROUGH THE
TN RIVER VALLEY AREA. AS A RESULT, THE BEST CHANCE FOR THUNDERSTORMS
WILL BE LIMITED TO THE FAR NORTHWEST TOMORROW DURING THE AFTERNOON
AND EARLY EVENING. WHILE A FEW RUMBLES OF THUNDER ARE POSSIBLE,
WIDESPREAD SEVERE WEATHER APPEARS UNLIKELY IN THIS DRY
ENVIRONMENT.
LONG TERM
(WEDNESDAY NIGHT THROUGH MONDAY)
ISSUED AT 455 AM EDT TUE MAY 19 2026
A WEAKENING COLD FRONT WILL HAVE ENTERED THE FAR NORTHERN TIER BY
THE TIME THE LONG TERM PERIOD PICKS UP ON WEDNESDAY EVENING.
SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS WILL LINGER ACROSS FAR
NORTH AND WEST GEORGIA IN THE CLOSEST VICINITY TO THE FRONT, THOUGH
COVERAGE WILL STEADILY DIMINISH AFTER SUNSET AND THUNDERSTORMS WILL
COME TO AN END AFTER MIDNIGHT. AS RIDGING OVER THE ATLANTIC COAST
AND WEST ATLANTIC CONTINUES TO FLATTEN, THE FRONT WILL MAKE SOME
MINIMAL PROGRESS SOUTHWARD DURING THE EARLY MORNING, EVENTUALLY
STALLING NORTH OF I-20 AMID SOUTHWESTERLY FLOW ALOFT DURING THE
DAYTIME ON THURSDAY. TEMPERATURES AND DEWPOINTS WILL START THE
MORNING ON THURSDAY IN THE MID TO UPPER 60S ACROSS THE AREA. HIGH
TEMPERATURES WILL BE SLIGHTLY COOLER ACROSS FAR NORTH GEORGIA (IN
THE LOW TO MID 80S) BEHIND THE FRONT COMPARED TO UPPER 80S ELSEWHERE
IN NORTH GEORGIA AND LOW 90S IN CENTRAL GEORGIA. HOT AND HUMID
CONDITIONS WILL SUPPORT DIURNALLY ENHANCED CONVECTION, WITH POPS
OF 60-80% IN THE NORTHERN HALF OF THE AREA CLOSEST TO THE FRONTAL
BOUNDARY, AND 30-50% IN THE SOUTHERN HALF OF THE AREA.
THE FRONT WILL BECOME LESS DEFINED AND BEGIN TO LIFT BACK NORTHWARD
ON FRIDAY WITHIN SOUTHWEST MID-LEVEL FLOW ALONG THE WESTERN
PERIPHERY OF THE ATLANTIC RIDGE. THIS SOUTHWESTERLY FLOW WILL
INTENSIFY AS A SECOND RIDGE APPROACHES FROM THE GREAT PLAINS, GIVING
THE FRONT AN ADDITIONAL PUSH AWAY TO THE NORTH. WHILE THIS RIDGE
SETS UP OVER THE EASTERN CONUS DURING THE WEEKEND, THE
AFOREMENTIONED SOUTHWESTERLY FLOW WILL CONTINUE TO SPREAD AMPLE
MOISTURE INTO THE FORECAST AREA. TEMPERATURES RISING INTO THE 80S
AND LOW 90S EACH DAY ALONG WITH AMPLE MOISTURE WILL LEAD TO
SCATTERED TO NUMEROUS DIURNAL CONVECTION EACH DAY THROUGH THE
WEEKEND INTO EARLY NEXT WEEK. COVERAGE OF STORMS WILL BE GREATEST
DURING THE AFTERNOON AND EVENING. AT THIS TIME, THE DEEPEST MOISTURE
AND HIGHEST PWATS WILL KEEP THE MOST CONSISTENT HEAVY RAINFALL WEST
OF GEORGIA.
