KEY MESSAGES
- RAINFALL THE PAST 24 HOURS DID INCREASE FUEL MOISTURE IN THE
SHORT TERM IN MANY AREAS. HOWEVER WE MAY SEE FIRE WEATHER
CONCERNS DUE TO BREEZY CONDITIONS AND LOW HUMIDITY ALONG THE
COAST COMBINE WITH LOWER FUEL MOISTURE MONDAY DEPENDING ON
RAINFALL TONIGHT.
- DAILY SCATTERED SHOWERS AND THUNDERSTORMS RETURN WEDNESDAY
THROUGH SATURDAY.
DISCUSSION
(THIS EVENING THROUGH NEXT SATURDAY)
ISSUED AT 1254 PM CDT SUN APR 5 2026
THE LAST OF THE SHOWERS ARE EXITING ST. MARY PARISH THIS
AFTERNOON WITH THE FRONT NOW WELL INTO THE COASTAL WATERS WHERE A
FEW SHOWERS REMAIN AS WELL. ANOTHER UPPER WAVE MOVING IN FROM THE
WEST THIS AFTERNOON WILL INCREASES SHOWERS AND POSSIBLY SOME
THUNDERSTORMS THIS AFTERNOON INTO THE OVERNIGHT ACROSS THE COASTAL
WATERS AND SOME OF THIS ACTIVITY COULD WORK INTO THE IMMEDIATE
COASTAL COUNTIES AND PARISHES.
OTHERWISE DRY AND COOL MONDAY THROUGH TUESDAY. SCATTERED SHOWERS
AND THUNDERSTORMS RETURN WEDNESDAY AS MOISTURE INCREASES FROM THE
SOUTHEAST ALONG WITH A SLOW WARMING TREND THAT WILL CONTINUE
THROUGH THE REMAINDER OF THE PERIOD. MAINLY DAYTIME SCATTERED SHOWERS
AND THUNDERSTORMS WILL CONTINUE THROUGH THE PERIOD WITH THE
GREATEST RAIN CHANCES WORKING EAST TO WEST THROUGH THE REMAINDER
OF THE PERIOD.
THE RAINFALL DID INCREASE FUEL MOISTURE IN THE SHORT TERM ACROSS
MOST OF THE AREA. DEPENDING ON ANY ADDITIONAL MOISTURE TONIGHT
THERE COULD BE A BRIEF WINDOW OF COMBINED LOWER HUMIDITY AND
CONTINUED GUSTY WINDS WITH SOME OF THE LOWER FUEL MOISTURE ACROSS
PORTIONS OF EAST TEXAS MONDAY. WILL CONTINUE TO MONITOR AS
CONDITIONS ARE MARGINAL.
AVIATION
(00Z TAFS)
ISSUED AT 626 PM CDT SUN APR 5 2026
SLIGHTLY ELEVATED, TO GUSTY AT TIMES, NORTHEAST WINDS ARE ONGOING
OVER THE REGION BEHIND THE DEPARTED COLD FRONT. HOWEVER, DRY AIR
HAS BEEN SLOW TO ARRIVE THANKS TO OVERRUNNING SHOWERY RAINFALL
NEAR AND OVER SOUTHWEST PORTIONS OF THE REGION. A FEW LIGHT
SHOWERS MAY CLIP INLAND SO FAR AS BPT AND LCH LATE TONIGHT, BUT
LARGELY THERE SHOULD BE LITTLE TO NO IMPACT AT TERMINALS.
WINDS SHIFT MORE TO THE EAST AS HIGH PRESSURE CONTINUES SHIFTING
TOWARDS ITS ANTICIPATED FINAL POSITION OVER THE MIDWEST US. ITS
INFLUENCE WILL EXPAND OUTWARD TO THE SOUTH KEEPING AN EASTERLY
FETCH OVER THE AREA FOR AN EXTENDED PERIOD. CLOUD CONDITIONS
SHOULD IMPROVE OVER THE PERIOD WITH THE INCREASE IN HIGH PRESSURE
INFLUENCE.
MARINE
ISSUED AT 1254 PM CDT SUN APR 5 2026
WINDS WILL CONTINUE TO BE BRISK OUT OF THE NORTH ACROSS THE ACROSS
MOST OF THE COASTAL WATERS THROUGH 1 PM MONDAY AND IN THE 20 TO
60 NM MILE AREA THROUGH AT LEAST 7 PM MONDAY. THUS A SMALL CRAFT
WILL REMAIN IN EFFECT THROUGH THE TIMES PREVIOUSLY MENTIONED. WILL
SEE WINDS SHIFT AROUND TO THE EAST SOUTHEAST TUESDAY AND BE
INCREASING AGAIN WHICH MAY REQUIRE THE ISSUANCE OF ANOTHER
ADVISORY IN THE FUTURE. ALSO SHOWERS AND THUNDERSTORMS COULD
INCREASE AGAIN TONIGHT AS ANOTHER FRONTAL WAVE MOVE ACROSS THE
GULF.
FIRE WEATHER
ISSUED AT 1254 PM CDT SUN APR 5 2026
WINDS WILL DIMINISH SOME MONDAY BUT REMAIN GUSTY WITH MIN RH'S IN
THE 25 TO 30 PERCENT RANGE ACROSS EAST TEXAS AND WESTERN
LOUISIANA AND THERE COULD BE A BRIEF WINDOW WHERE THESE TWO
PARAMETERS COMBINE TO INCREASE FIRE WEATHER CONCERNS MONDAY,
ESPECIALLY IN AREAS WHERE FUEL MOISTURE REMAIN DRY AND THIS LOOKS
TO BE MAINLY ACROSS SOUTHEAST TEXAS AT THIS TIME.
WINDS WILL CONTINUE TO DECREASE TUESDAY WITH RH'S AROUND 30
PERCENT.
