GOES TOTAL PW IMAGERY SHOWS A TONGUE OF LOW MOISTURE VALUES
STRETCHING INLAND FROM THE GULF AND ENCOMPASSING MOST OF THE
AREA...EXCEPTION BEING EXTREME WESTERN ZONES WHERE THERE'S A FEW
WEAK SHOWERS SHOWING UP ON RADAR. THESE SHOULD DISSIPATE BY EARLY
EVENING. WITH WX PATTERN REMAINING ABOUT AS-IS (MID/UPPER RIDGING
FROM MEXICO STRETCHING NNEWD ACROSS EASTERN TX, LLVL ONSHORE FLOW),
ONE WOULD EXPECT WX TO REMAIN ABOUT STATUS QUO TOO. LOOK FOR LATE
NIGHT/EARLY MORNING CLOUDINESS AND PATCHY FOG FOLLOWED BY PCLDY
AFTERNOONS. TEMPS WILL BE RUNNING ABOUT 5-10F ABOVE SEASONABLE
NORMS AND RAIN CHANCES, THOUGH NOT EXACTLY ZERO, AREN'T WORTH
MENTIONING. 47
LONG TERM
(MONDAY THROUGH NEXT FRIDAY)
ISSUED AT 208 PM CDT SAT APR 26 2025
WE WILL KICK OFF THE WORK WEEK WITH QUIET WEATHER AS A BROAD UPPER
LEVEL RIDGE REMAINS DRAPED ACROSS THE GREAT PLAINS. EXPECT A
TRANSITION TO BEGIN AS WE HEAD INTO MIDWEEK WITH A CLOSED LOW OVER
THE GREAT BASIN/ROCKY MOUNTAINS EVOLVES INTO AN UPPER-LEVEL TROUGH
AND DEEPENS AS IT PROGRESSES EASTWARD. THIS WILL LEAD TO AN INCREASE
IN RAIN CHANCES TUESDAY AS THIS SYSTEM NEARS SE TEXAS. ENERGY PULSES
AT THE H5 LEVEL ARE EXPECTED TO COME AROUND THE PERIPHERY OF THE
TROUGH AND AID IN UPWARD MOVEMENT OF AIR AND CONSEQUENTLY SHOWER AND
THUNDERSTORM DEVELOPMENT THROUGH THE WEEK. MODELS CONTINUE TO
INDICATE A SLOW MOVING COLD FRONT/QUASI-STATIONARY BOUNDARY OVER
PORTIONS OF OKLAHOMA/ARKLATEX ON WEDNESDAY. WHILE HIGHER RAINFALL
TOTALS ARE EXPECTED TO BE WELL NORTH OF THE CWA, THIS BOUNDARY AND
THE SHORTWAVE IN THE VICINITY WILL HELP TO BRING AROUND 0.25-0.75"
OF RAINFALL TO AREAS NORTH OF I-10 WITH LESS THAN 0.5" PROJECTED FOR
AREAS SOUTH OF I-10 FROM TUESDAY THROUGH THE END OF THE WEEK. WITH
THIS BEING LATER IN THE PERIOD, THESE TOTALS ARE LIKELY GOING TO
CHANGE OVER THE NEXT FEW DAYS. CURRENT GUIDANCE SHOWS THE BOUNDARY
PUSHING SOUTHWARD NEAR THE END OF THE WEEK NEXT WEEK...AGAIN, IT IS
TOO LATE IN THE PERIOD TO SAY WITH CERTAINTY WHAT THE TIMING OF
A FROPA WILL BE.

(00Z TAF ISSUANCE)
ISSUED AT 602 PM CDT SAT APR 26 2025
SOUTHEASTERLY WINDS WILL BE ON A DECREASING TREND HEADING INTO THE
EVENING HOURS. THE MAIN IMPACT WILL BE THE INFLUX OF MVFR CEILINGS
FROM SOUTH TO NORTH OVERNIGHT. THERE MAY BE SOME INTERMITTENT
PERIODS OF HIGH-END IFR CEILINGS AT SOME SPOTS. PATCHY FOG MAY
LEAD TO DECREASED VISIBILITIES AT CXO/UTS/CLL MAINLY BETWEEN A
TIMEFRAME OF 09Z-15Z. CEILINGS AND VISIBILITIES IMPROVE AFTER 15Z
ON SUNDAY MORNING AND EVENTUALLY BECOME VFR AS SOUTHEASTERLY
WINDS INCREASE. EXPECT SUSTAINED WINDS OF 10-15 KT WITH GUSTS UP
TO 20-25 KT THROUGH THE AFTERNOON.

ISSUED AT 602 PM CDT SAT APR 26 2025
ONSHORE FLOW WILL CONTINUE THROUGHOUT THE WEEKEND AND WELL INTO NEXT
WEEK. TOWARDS THE BEGINNING TO MIDDLE OF NEXT WEEK, EXPECT INCREASED
WINDS AND SEAS THAT COULD REACH CAUTION FLAG CRITERIA AT TIMES. THIS
WILL BRING AN INCREASED RISK OF RIP CURRENTS ALONG WITH ELEVATED
WATER LEVELS DURING TIMES OF HIGH TIDE THAT COULD POTENTIALLY RESULT
IN MINOR COASTAL FLOODING. PETSS GUIDANCE CURRENTLY SHOWING
POTENTIAL FOR WATER LEVELS TO REACH AS HIGH AS 3.0-3.5 FT ABOVE
MLLW AS EARLY AS MONDAY NIGHT/TUESDAY MORNING'S HIGH TIDE CYCLE.
CHANCES FOR SHOWERS AND STORM RETURN TOWARDS THE MIDDLE OF NEXT
WEEK AS THE NEXT WEATHER SYSTEM APPROACHES.
