DISCUSSION
ISSUED AT 1140 PM CDT MON SEP 14 2026
AN UPPER RIDGE OVER THE REGION RETREATS FROM THE AREA LATE THIS
WEEK AND INTO SATURDAY AS AN UPPER LOW/TROF FORMS OVER THE FAR
WESTERN ATLANTIC AND ADVANCES INTO THE NORTHEAST GULF. A SURFACE
RIDGE BUILDS INTO THE SOUTHEASTERN STATES THROUGH MIDWEEK, SETTING
UP AN EASTERLY SURFACE FLOW WHICH USHERS DRIER AIR INTO THE
FORECAST AREA. ISOLATED SHOWERS AND STORMS WILL BE POSSIBLE OVER
THE COASTAL COUNTIES TUESDAY AFTERNOON WITH THE SEABREEZE, BUT
OTHERWISE SUBSIDENCE ASSOCIATED WITH THE UPPER RIDGE WILL SUPPRESS
CONVECTIVE DEVELOPMENT. THE EASTERLY SURFACE FLOW WITH THE
BUILDING SURFACE RIDGE STRENGTHENS MAINLY OVER THE MARINE AREA
TUESDAY NIGHT INTO WEDNESDAY, AND ISOLATED TO SCATTERED CONVECTION
DEVELOPS IN RESPONSE OVER THE MARINE AREA WHICH MAY AFFECT MAINLY
COASTAL PORTIONS OF ALABAMA. DRY CONDITIONS OTHERWISE PREVAIL
THROUGH FRIDAY, THEN SLIGHT CHANCE TO CHANCE POPS RETURN TO THE
FORECAST ON SATURDAY AS THE UPPER LOW PROGRESSES INTO THE
NORTHEASTERN GULF ALONG WITH A MODEST SURFACE REFLECTION TROF AND
IMPROVING DEEP LAYER MOISTURE. CHANCE TO LIKELY POPS FOLLOW FOR
SUNDAY AS THE UPPER LOW LOOKS TO SLOWLY PROGRESS A BIT FURTHER
ACROSS THE GULF ALONG WITH DEEP LAYER MOISTURE CONTINUING TO
INCREASE.
A LOW RISK OF RIP CURRENTS ON TUESDAY IS EXPECTED TO QUICKLY
INCREASE TO A HIGH RISK FOR WEDNESDAY AND THURSDAY, THEN A
MODERATE RISK FOLLOWS FOR FRIDAY. AS NOTED BY THE PREVIOUS SHIFT,
WILL NEED TO MONITOR SURF HEIGHTS WHICH ARE EXPECTED TO INCREASE
TO 4-5 FEET ON WEDNESDAY AND THURSDAY. SHOULD THESE INCREASE
FURTHER, THEN A HIGH SURF ADVISORY WOULD LIKELY BECOME NECESSARY
FOR THESE DAYS. HEAT INDEX VALUES OF 100-107 ARE EXPECTED FOR
TUESDAY, BUT OTHERWISE A COMBINATION OF SOMEWHAT COOLER DAYTIME
HIGHS AND/OR LOWER SURFACE DEWPOINTS WILL LIMIT HEAT INDEX
VALUES. /29
