KEY MESSAGES
- A WARMING TREND TO CONTINUE FOR MOST OF THE FORECAST PERIOD.

INTERIOR SETX AND CENLA THIS WEEKEND AND EARLY NEXT WEEK.

SHORT TERM
(TODAY THROUGH MONDAY NIGHT)
ISSUED AT 1233 AM CDT SAT MAR 21 2026
SOMEWHAT COOL ALBEIT HUMID CONDITIONS WITH TEMPS IN THE 50S TO 60S
AND NEAR MATCHING DEWPOINTS. AS OF 05Z, ONLY A FEW AREAS OF DENSE
FOG WERE NOTED VIA SATELLITE AND OBS SITES. THIS IS EXPECTED TO
CHANGE WITH PATCHY TO DENSE FOG LIKELY FOR MOST OF THE CWA. WE COULD
SEE VISIBILITIES ONCE AGAIN FALL INTO DENSE FOG ADVISORY CRITERIA.
REGARDLESS OF ISSUANCE, ONE SHOULD BE CAUTIOUS WHILE COMMUTING THIS
MORNING. FOG WILL BURN OFF SHORTLY AFTER SUNRISE.
A SURFACE HIGH PRESSURE WILL MEANDER EAST AND SOUTH OF THE FORECAST
AREA THROUGH THE REMAINDER OF THE PERIOD WITH SOUTHERLY FLOW
PREVAILING THROUGH THE NEXT SEVERAL DAYS. ALOFT, A STRONG RIDGE OVER
THE DESERT SW WILL EVER SO SLIGHTLY WEAKEN GOING INTO THE WORK WEEK
AS IT DRIFTS SSE. THIS RIDGE IN COMBINATION WITH A TROUGH OVER THE
ATLANTIC COAST WILL ALLOW FOR NORTHERLY TO NORTHWESTERLY FLOW TO
PREVAIL ALOFT. WE CAN EXPECT THE WARMING TREND TO CONTINUE AS
DAYTIME HIGHS RISE (AND OVERNIGHT LOWS FALL) TO ABOUT 10 DEGREES
ABOVE NORMAL GOING INTO THE CONSECUTIVE WORK WEEK.
LONG TERM
(TUESDAY THROUGH SATURDAY)
ISSUED AT 1233 AM CDT SAT MAR 21 2026
FROM THE MID WEEK PERIOD TO THE END OF THE WEEK, THE UPPER RIDGE
WILL BE OVER THE DESERT SW, HEADING EASTWARD INTO TX. AT THE
SURFACE, AREAS OF HIGH PRESSURE WILL BE OVER THE EAST COAST AND
GULF.
DESPITE THE STREAM OF SOUTHERLY FLOW CONTINUING, SHOWERS ARE NOT
EXPECTED. A WEAK AND DRY COOL FRONT IS PROJECTED TO PROGRESS THROUGH
THEN SLOW AND BISECT THE CWA AS IT BEGINS RETROGRADING. THIS WILL
PROVIDE NO REAL RELIEF IN THE WAY OF COOLING.
FOR THE REST OF THE LONG TERM, SIMILAR TEMPERATURE CONDITIONS AND
LACK OF RAIN WILL PREVAIL.
AVIATION
(06Z TAFS)
ISSUED AT 1228 AM CDT SAT MAR 21 2026
MOSTLY VFR CONDITIONS STILL ONGOING, HOWEVER THIS IS NOT EXPECTED
TO LAST WITH LIGHT PATCHY TO DENSE FOG LIKELY TO SHROUD SOME OF
THE TERMINALS. WHATEVER FOG THAT FORMS WILL BURN OFF AFTER SUNRISE
AND VFR CONDITIONS WILL PREVAIL AFTER THAT. OTHERWISE, THIS IS A
WIND FORECAST, WITH ELEVATED AND GUSTY SOUTHERLY TO SOUTHWESTERLY
WINDS PICKING UP IN THE AFTERNOON BEFORE TAPERING ONCE AGAIN IN
THE EVENING.
MARINE
ISSUED AT 1233 AM CDT SAT MAR 21 2026
LIGHT MAINLY S TO SW WINDS AND LOW SEAS WILL CONTINUE THROUGH THE
WEEKEND INTO EARLY NEXT WEEK AS SURFACE HIGH PRESSURE LINGERS TO OUR
EAST. RIDGING BUILDING IN ALOFT WILL KEEP DRY CONDITIONS IN PLACE,
WITH NO PRECIPITATION EXPECTED THROUGH THE FORECAST PERIOD.
FIRE WEATHER
ISSUED AT 1233 AM CDT SAT MAR 21 2026
WARM AND DRY CONDITIONS PREVAIL THROUGH THE WEEKEND INTO EARLY NEXT
WEEK AS UPPER RIDGING BUILDS ACROSS THE COUNTRY. MINRH VALUES WILL
GENERALLY RANGE FROM THE LOW TO MID 40S FOR INLAND LOCATIONS, AND
FROM THE UPPER 40S TO UPPER 50S FOR AREAS ALONG/SOUTH OF I-10. WHILE
MOISTURE SLOWLY RETURNS THROUGH THE PERIOD, NO RAINFALL IS EXPECTED
FOR THE FORESEEABLE FUTURE.
