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 1227 AM CDT SUN MAR 22 2026
A SIGNIFICANT MID-LEVEL HIGH-PRESSURE SYSTEM IS LOCATED TO OUR
WEST, OVER NEW MEXICO/ARIZONA. AT THE SURFACE, HIGH PRESSURE IS
LOCATED IN THE EASTERN GULF AND WILL KEEP OUR WINDS SOUTHERLY,
PUSHING WARM, MOIST AIR NORTH. THE PERSISTENT SOUTHERLY FLOW WILL
KEEP THE SURFACE MOIST ENOUGH TO CAUSE PATCHY FOG, MAINLY ALONG
THE COAST, ALONG WITH CLOUDY MORNINGS.
EVEN WITH THE CENTER OF THE RIDGE WELL TO OUR WEST, 500 MB HEIGHTS
WILL REMAIN NEAR THE 90TH PERCENTILE FOR THE REMAINDER OF THE
FORECAST. FOR THE REST OF THE WEEKEND AND GOING INTO NEXT WEEK,
OUR WEATHER PATTERN WILL REMAIN FAIRLY CONSISTENT, WITH ANY DAY-
TO-DAY CHANGES EXPECTED TO BE MINOR. HIGH TEMPERATURES WILL BE 10
TO 15 DEGREES ABOVE NORMAL, WITH HIGHS IN THE MID TO UPPER 80S.
EXPECT NEAR-RECORD-BREAKING HEAT, AND FRIDAY OF NEXT WEEK, THERE
IS AROUND A 20% CHANCE WE COULD SEE HIGHS IN THE 90S FOR PARTS OF
CENTRAL LOUISIANA AND PARTS OF SOUTHEAST TEXAS. EVEN THOUGH WE
ARE NOT IN THE HEAT OF SUMMER YET, MAKE SURE TO STAY COOL AND
HYDRATED!
RAIN CHANCES WILL REMAIN NEAR ZERO FOR THE REST OF THE WEEKEND
AND INTO NEXT WEEK. A BACKDOOR COLD FRONT WILL MOVE ACROSS THE
REGION FROM THE NORTHEAST ON TUESDAY. HOWEVER, THE MAIN IMPACT
WILL BE A SLIGHT DECREASE IN HUMIDITY. NEAR THE MIDDLE OF NEXT
WEEK, MODELS HAVE STARTED TO HINT AT THE POSSIBILITY OF AN
INCREASE IN RAIN CHANCES, BUT THERE IS NOT ENOUGH CONFIDENCE TO
INCREASE RAIN CHANCES YET. WITH THE HOT AND DRY WEATHER, EXPECT
DROUGHT CONDITIONS TO WORSEN OVER THE NEXT WEEK.
AVIATION
(06Z TAFS)
ISSUED AT 1227 AM CDT SUN MAR 22 2026
PATCHY FOG REMAINS THE MAIN CONCERN FOR TONIGHT, WITH PERSISTENT
MVFR CONDITIONS ALONG WITH TEMPORARY LIFR RESTRICTIONS BEFORE
MIDNIGHT. AFTER SUNRISE, CONDITIONS WILL QUICKLY IMPROVE TO VFR
WITH NO OTHER IMPACTS EXPECTED FOR THE REST OF THE DAY.
MARINE
ISSUED AT 1227 AM CDT SUN MAR 22 2026
HIGH PRESSURE WILL LEAD TO PERSISTENT LIGHT TO MODERATE ONSHORE
FLOW. WAVES REMAIN BELOW FOUR FEET FOR THE REMAINDER OF THE WEEK.
RAIN AND THUNDERSTORM CHANCES WILL REMAIN NEAR ZERO FOR THE REST
OF THE FORECAST.
FIRE WEATHER
ISSUED AT 1227 AM CDT SUN MAR 22 2026
DRY AND WARM WEATHER WILL CONTINUE FOR THE REST OF THE WEEKEND AND
THROUGH NEXT WEEK AS HIGH PRESSURE DOMINATES OUR WEATHER PATTERN.
HIGH PRESSURE TO OUR EAST IS CAUSING PERSISTENT SOUTHERLY FLOW,
WITH RH RECOVERING TO NEAR 100% EACH NIGHT. DURING THE AFTERNOON,
PERSISTENT SUNSHINE AND ABOVE-SEASONAL TEMPERATURES WILL CAUSE RH
VALUES TO DROP TO THE 40 TO 50% RANGE. KBDI VALUES ARE BETWEEN 250
TO 350, AND THERE IS NO CHANCE FOR SUBSTANTIAL RAIN IN THE
FORECAST.
