LONG TERM
(SUNDAY MORNING THROUGH NEXT THURSDAY)
ISSUED AT 226 PM EDT FRI MAR 28 2025
KEY MESSAGES:
- STRONG TO SEVERE THUNDERSTORMS POSSIBLE ACROSS PORTIONS OF THE
AREA SUNDAY NIGHT AND MONDAY.
THE LONG TERM PERIOD WILL START WITH A WEAKENING UPPER TROUGH FROM S
GA INTO THE E GULF. ANOTHER SHORTWAVE WILL PUSH E FROM THE CENTRAL
MS VALLEY TO THE MID-ATLANTIC REGION FROM LATE SUNDAY INTO MONDAY.
BOTH OF THESE FEATURES WILL BE FAIRLY WEAK, BUT MOISTURE AND
INSTABILITY WILL BE INCREASING. ADDITIONALLY, AN APPROACHING COLD
FRONT WILL PROVIDE ADDITIONAL LIFT. AS A RESULT, THE CHANCES OF
THUNDERSTORMS WILL BE INCREASING. STORMS WILL BE LESS ORGANIZED ON
SUNDAY AFTERNOON, BUT A MORE ORGANIZED LINE OF STORMS IS FORECAST TO
APPROACH NW GA SUNDAY EVENING. THESE STORMS MAY WEAKEN SUNDAY NIGHT,
BUT RE-DEVELOPMENT IS FORECAST DURING THE DAY MONDAY ACROSS THE AREA.
SPC HAS NW GEORGIA IN A SLIGHT SEVERE RISK AREA SUNDAY NIGHT, WITH A
15% RISK AREA ACROSS MOST OF THE STATE FOR MONDAY. CAPE VALUES ARE
FORECAST TO RAMP UP TO OVER 1500 J/KG WITH EFFECTIVE SHEAR OF AT
LEAST 40 KTS DURING PEAK DAYTIME HEATING ON MONDAY, SO SEVERE
PARAMETERS WILL BE IN PLACE. THE GREATEST THREAT APPEARS TO BE GUSTY
WINDS WITH LESSER THREATS FOR TORNADOES AND HAIL.
QPF AMOUNTS WITH THIS STORM SYSTEM CONTINUE TO BECOME MORE UNIFORM
ACROSS THE AREA DUE TO THE ANTICIPATED RE-DEVELOPMENT OF HEAVIER
RAINS ON MONDAY. STORM TOTAL RAINFALL AMOUNTS ARE FORECAST TO AVERAGE
AROUND 1.5" ALMOST AREA-WIDE, WITH SLIGHTLY LOWER TOTALS IN THE SE
ZONES. WPC IF PAINTING A MARGINAL RISK OF EXCESSIVE RAINFALL AS
CONVECTION SWEEPS ACROSS THE AREA. THE GREATEST RISK OF LOCALIZED
FLOODING WOULD BE IN AREAS WITH TRAINING STORMS OR HEAVIER STORMS.
RIVER FLOODING IS NOT ANTICIPATED AT THIS TIME.
ANOTHER STORM SYSTEM MAY SWEEP ACROSS THE OH VALLEY AROUND THE
MIDDLE OF NEXT WEEK, WITH MORE SHOWERS AND THUNDERSTORMS POSSIBLE
WEDNESDAY AND THURSDAY.
TEMPERATURES WILL RUN WELL ABOVE NORMAL THROUGH MOST OF THE PERIOD
(10 TO 15 DEGREES ABOVE NORMAL), ALTHOUGH READINGS WILL DROP BACK
CLOSER TO NORMAL BEHIND THE FRONT EARLY NEXT WEEK (STILL ABOUT 5
DEGREES ABOVE NORMAL). A RETURN TO WELL ABOVE NORMAL TEMPERATURES IS
FORECAST BY THE END OF THE FORECAST PERIOD. /SEC
