KEY MESSAGES
- A PERSISTENT SOUTHERLY FLOW WILL BRING IN A WARM GULF AIR MASS THAT
WILL ALLOW FOR ABOVE SEASONAL TEMPERATURES THIS WEEK WITH SOME
AFTERNOON HIGHS NEARING DAILY RECORDS.
- UPPER LEVEL RIDGING AND DRY AIR ALOFT WILL HELP KEEP ANY CHANCE OF
RAIN OUT OF THE FORECAST INTO NEXT WEEK.
DISCUSSION
ISSUED AT 154 PM CDT SAT MAR 21 2026
FOR THE REMAINDER OF THE WEEKEND INTO NEXT WEEK THE WEATHER PATTERN
WILL GENERALLY SHOW AN UPPER LEVEL RIDGE OVER THE SOUTHWEST US WITH
A TROUGH ALONG THE EAST COAST. THIS WILL BRING A RATHER BENIGN WEST-
NORTHWEST FLOW ALOFT OVER THE FORECAST AREA.
AT THE SURFACE, HIGH PRESSURE WILL RIDGE ACROSS THE NORTHERN GULF
FROM THE SOUTHEAST US FOR THE REMAINDER OF THE WEEKEND INTO EARLY
NEXT WEEK THAT WILL BRING A LOW LEVEL SOUTHERLY FLOW. SOME PATCHY
FOG MAY OCCUR DURING THE OVERNIGHT TO SHORTLY AFTER SUNRISE AS CLEAR
SKIES, LIGHT WINDS, AND ADEQUATE LOW LEVEL MOISTURE WILL BRING A
CHANCE FOR RADIATIONAL FOG, MAINLY IN RURAL AREAS.
A BACKDOOR COLD FRONT WILL TRY TO MOVE DOWN FROM THE NORTHEAST INTO
THE FORECAST AREA ON TUESDAY, HOWEVER IT LOOKS TO RUN OUT OF STEAM
AS IT REACHES THE REGION, AND IS NOT EXPECTED TO HAVE ANY AFFECT
BEFORE IT DISSIPATES ON WEDNESDAY.
THEREFORE, THE FORECAST PERIOD WILL BE NOTED BY UNSEASONABLY WARM
EARLY SPRING TEMPERATURES WITH READINGS SOME 10 TO 15 DEGREES ABOVE
DAILY CLIMO NORMS WITH SOME AFTERNOON HIGHS NEARING DAILY RECORDS AS
THE WEEK PROGRESSES.
ALSO, WITH MAINLY RIDGING AND DRY AIR ALOFT, NO SIGNIFICANT RAIN
FALL IS EXPECTED DURING THE PERIOD, THAT WILL LIKELY ALLOW DROUGHT
CONDITIONS TO INCREASE AGAIN.

SURFACE HIGH WILL BE RIDGING ACROSS THE NORTHERN GULF FROM AROUND
FLORIDA AND OFF THE SOUTHEAST US COAST. THEREFORE, A LIGHT TO MODEST

FIRE WEATHER
ISSUED AT 154 PM CDT SAT MAR 21 2026
SURFACE HIGH PRESSURE OFF TO THE EAST WILL KEEP A SOUTHERLY FLOW IN
PLACE FOR THE REMAINDER OF THE WEEKEND INTO EARLY NEXT WEEK. THIS
WILL ALLOW FOR MODEST GULF MOISTURE OVER THE AREA WITH WITH MINIMUM
AFTERNOON RELATIVE HUMIDITY VALUES BETWEEN 40 AND 50 PERCENT. SOME
PATCHY FOG WILL BE POSSIBLE LATE AT NIGHT AND DURING THE EARLY
MORNING ESPECIALLY FOR LOCATIONS THAT MAY HAVE RESIDUAL SMOKE FROM
EARLIER BURNINGS. NO CHANCE FOR SIGNIFICANT RAIN AS AN UPPER LEVEL
RIDGE INFLUENCES THE WEATHER.
