1121 PM EDT MON MAR 09 2026
AREAS AFFECTED...CENTRAL AL INTO WEST-CENTRAL GA
CONCERNING...HEAVY RAINFALL...FLASH FLOODING POSSIBLE
VALID 100320Z - 100715Z
SUMMARY...A LOCALIZED RISK OF FLASH FLOODING WILL PERSIST ACROSS
CENTRAL AL INTO WEST-CENTRAL GA THROUGH 06Z TO 07Z. TRAINING WITH
PEAK RAINFALL RATES OF 0.5 TO 1.0 INCHES IN 15 MINUTES AND UP TO
2-3 INCHES TOTAL RAINFALL MAY OCCUR.
DISCUSSION...03Z RADAR IMAGERY FROM KFFC SHOWED AN MCV JUST
NORTHWEST OF ATLANTA, ASSOCIATED WITH A WEAKENING CONVECTIVE
CLUSTER OVER THE AL/GA BORDER. THE MCV WAS TRACKING STEADILY
TOWARD THE EAST AND CLOUD TOPS HAVE BEEN WARMING ON INFRARED
IMAGERY OVER THE PAST 1-2 HOURS AS INSTABILITY WEAKENS. HOWEVER, A
REMNANT OUTFLOW BOUNDARY WAS ANALYZED FROM WESTERN GA INTO CENTRAL
AL, AND WAS ALIGNED WNW TO ESE OR PARALLEL TO MEAN STORM MOVEMENT.
MLCAPE HAS BEEN LOWERING PER SPC MESOANALYSIS TRENDS BETWEEN 00Z
AND 03Z BUT 500-1000 J/KG LIKELY REMAINED ALONG AND SOUTH OF THE
OUTFLOW BOUNDARY.
SOME ASCENT WILL REMAIN ACROSS THE REGION AHEAD OF A MID-LEVEL
SHORTWAVE LOCATED OVER THE MO BOOTHEEL AT 03Z, WITH 20-30 KT OF
SOUTHWESTERLY 925-850 MB FLOW OVERRUNNING THE OUTFLOW BOUNDARY
FROM MS INTO AL AND GA. WHILE THE WINDOW FOR FLASH FLOODING IS
SHRINKING, THERE WILL REMAIN SOME LIMITED POTENTIAL FOR AN
ADDITIONAL 1-3 INCHES OF RAIN FROM PORTIONS OF CENTRAL AL INTO
WEST-CENTRAL GA.
