..NEW SHORT TERM, LONG TERM, MARINE
SHORT TERM
(TONIGHT THROUGH MONDAY NIGHT)
ISSUED AT 349 PM CST SUN NOV 17 2024
KEY MESSAGES:
- MARGINAL RISK FOR SEVERE THUNDERSTORMS EARLY MONDAY MORNING
- SMALL CRAFT ADVISORY IN EFFECT THROUGH MONDAY EVENING
- COASTAL FLOOD ADVISORY IN EFFECT THROUGH MONDAY
- HIGH RISK OF RIP CURRENTS THROUGH MONDAY
- LOW TO MEDIUM CHANCE FOR GALE FORCE WINDS ACROSS THE GULF WATERS
AS MOISTURE CONTINUES TO INCREASE AHEAD OF THE APPROACHING COLD
FRONT, RAIN CHANCES WILL INCREASE TO MEDIUM TO HIGH (50-80%) ACROSS
THE COASTAL PLAINS AND VICTORIA CROSSROADS. DESPITE RAIN CHANCES
INCREASING, RAINFALL ACCUMULATIONS ARE EXPECTED TO REMAIN BLEAK
UNDER 0.50" AS THE SHOWERS AND THUNDERSTORMS ARE EXPECTED TO MOVE
RATHER QUICKLY. RAIN CHANCES ARE EXPECTED TO QUICKLY TAPER OFF EARLY
TOMORROW AFTERNOON WITH RAIN FREE CONDITIONS LATE TOMORROW AFTERNOON
INTO TOMORROW EVENING. DUE TO THE POSITIONING OF THE LOW LEVEL JET,
A SEVERE THUNDERSTORM OR TWO CAN'T BE RULED OUT ACROSS THE VICTORIA
CROSSROADS WITH STRONG WINDS AS THE ONLY THREAT EXPECTED AT THIS
TIME. THEREFORE, SPC HAS PLACED THAT AREA UNDER A MARGINAL RISK
(LEVEL 1 OF 5) OF SEVERE THUNDERSTORMS.
STRONG WINDS AHEAD OF THE FRONT HAVE DEVELOPED EARLY THIS AFTERNOON
AND WILL CONTINUE THROUGH TONIGHT. WITH SEVERAL MODELS SHOWING HIGH
CHANCES FOR WIND GUSTS OVER 40 MPH, WENT AHEAD AND ISSUED A WIND
ADVISORY FOR THE SOUTHERN COASTAL PLAINS AND THE BRUSH COUNTRY FROM
THIS EVENING INTO TONIGHT. WITH WINDS OVER THE GULF WATERS EXPECTED
TO BE A TOUCH WEAKER, OPTED NOT TO ISSUE A GALE WARNING AT THIS
TIME, HOWEVER, THERE IS STILL A LOW TO MEDIUM FOR GALE FORCE WIND
GUST OVER THE LOCAL WATERS TONIGHT AFTER MIDNIGHT AND CONTINUE
THROUGH TOMORROW MORNING.
THE STRONG WINDS THIS AFTERNOON THROUGH TONIGHT WILL CONTINUE TO
PROMOTE HIGHER THAN NORMAL WATERS LEVELS ACROSS THE BEACHES OF THE
MIDDLE TEXAS COAST. WITH WATER LEVELS RUNNING ABOUT 1.2-1.4" ABOVE
PREDICTED, WILL CONTINUE THE COASTAL FLOOD ADVISORY AS WATER LEVELS
ARE EXPECTED TO REACH NEAR 2.5 FEET ABOVE MEAN SEA LEVEL DURING
TIMES OF HIGH TIDES. THE STRONG WINDS WILL ALSO PROMOTE A HIGHER
RISK OF RIP CURRENTS.
LASTLY, ELEVATED FIRE WEATHER CONDITIONS ARE POSSIBLE TOMORROW FROM
MCMULLEN TO BEE COUNTIES. WHILE RELATIVE HUMIDITY LEVELS WILL BE
BELOW CRITICAL LEVEL ACROSS THE BRUSH COUNTRY, WINDS ARE EXPECTED TO
DECREASE BY THEN WHICH WILL HELP HINDER THE THREAT FOR ELEVATED FIRE
WEATHER. HOWEVER, ACROSS THE AFOREMENTIONED COUNTIES, THE ENERGY
RELEASE COMPONENT WILL RANGE FROM THE 50TH-89TH PERCENTILE WHICH
WOULD HELP OVERCOME THE NEGATIVE INFLUENCE OF THE WEAKER WINDS TO
RESULT IN THE MEDIUM TO HIGH CHANCE FOR ELEVATED FIRE WEATHER
CONDITIONS. DID NOT ISSUE A FIRE DANGER STATEMENT AT THIS TIME TO
ALLOW THE NEXT SHIFT TO LOOK AT MORE RECENT MODEL DATA AND TRENDS TO
CONFIRM THE DECREASE IN WINDS. IF WINDS DON'T SUBSIDE AS FORECASTED
WITH THIS PACKAGE, THERE WILL BE A LOW TO MEDIUM CHANCE THAT
CRITICAL FIRE WEATHER CONDITIONS COULD DEVELOP.
LONG TERM
(TUESDAY THROUGH NEXT SATURDAY)
ISSUED AT 349 PM CST SUN NOV 17 2024
KEY MESSAGES:
- FALL TEMPERATURES FINALLY ARRIVE THIS WEEK.
I COULD HAVE CHANGED THE KEY MESSAGES BUT I FEEL LIKE THIS IS A NICE
WAY TO START OUR LONG TERM DISCUSSION AGAIN. COLD(ER) AIR WILL
FINALLY ARRIVE TUESDAY NIGHT AS A SURGE OF REINFORCING HIGH PRESSURE
MOVES INTO SOUTH TEXAS. HIGHS ARE EXPECTED TO BE NEAR NORMAL (70S
AND LOW 80S) FOR THIS TIME OF YEAR WHICH IS SIGNIFICANTLY COOLER
THAN WE'VE BEEN. WHILE THE PREVIOUS FORECAST MENTIONED TEMPERATURES
BELOW 40, I WILL NOT. ONLY BECAUSE THAT'S TOO COLD FOR ME--THERE IS
STILL A LOW CHANCE THAT IT COULD HAPPEN ON WEDNESDAY NIGHT.
TEMPERATURES WILL SLOWLY WARM BACK UP THROUGH WEEKEND WITH THE
POTENTIAL FOR MID-80S BY SATURDAY AS SOUTHEASTERLY FLOW RETURNS.
AVIATION
(18Z TAFS)
ISSUED AT 1136 AM CST SUN NOV 17 2024
MAINLY VFR CONDITIONS ARE EXPECTED THIS AFTERNOON WITH STRONG
WINDS AHEAD OF OUR NEXT COLD FRONT. MVFR CEILINGS WILL DEVELOP
TONIGHT AROUND 04-06Z AS WINDS REMAIN STRONG AND GUSTY OVERNIGHT.
ALTHOUGH NOT IN THE TAFS DUE TO LOW CONFIDENCE, LOW LEVEL WIND
SHEAR WILL BE POSSIBLE ACROSS LRD AND COT TOMORROW MORNING FROM
10-15Z. WINDS WILL REMAIN OUT OF THE SOUTHEAST THROUGH TONIGHT
WITH WINDS SHIFTING TO THE NORTHWEST ACROSS THE WESTERN SITES
AROUND 12-15Z AND THE EASTERN SITES BETWEEN 16-18Z. SHOWERS ARE
POSSIBLE FROM 14-18Z TOMORROW MORNING ACROSS THE EASTERN SITES,
HOWEVER, DUE TO THE LOW CONFIDENCE ON LOCATION AND COVERAGE, DID
NO INCLUDE IN THE TAFS AT THIS TIME.

ISSUED AT 349 PM CST SUN NOV 17 2024

CONDITIONS OVER THE GULF WATERS AND THE BAYS FOR WINDS FROM 20 TO 30

WITH RAIN CHANCES DECREASING LATE TOMORROW AFTERNOON IN THE WAKE OF
THE FRONT. THERE IS STILL A LOW TO MEDIUM FOR GALE FORCE WIND GUST
OVER THE LOCAL WATERS TONIGHT AFTER MIDNIGHT AND CONTINUE THROUGH
TOMORROW MORNING. THE FRONT IS EXPECTED TO SWEEP ACROSS THE LOCAL
WATERS TOMORROW FROM NOON TO 3 PM AND SHIFT THE WINDS FROM THE
