SHORT TERM
(TODAY THROUGH SUNDAY NIGHT)
ISSUED AT 341 AM CST SAT FEB 22 2025
THE WEATHER THIS WEEKEND WILL BE DOMINATED BY A COASTAL LOW THAT WILL BRING
PERIODS OF RAIN, GUSTY COASTAL WINDS, AND POTENTIALLY A FEW THUNDERSTORMS.
CLOUD COVER AND CONTINUED CAA IN THE LOW LEVELS WILL KEEP THE NEAR SFC COLD
AND STABLE. PERIODS OF LOW CLOUDS, DRIZZLE, AND REDUCED VISIBILITY ARE LIKELY.
HOWEVER, THERE MAY BE ENOUGH LIFT ALOFT TO ALLOW FOR SOME ELEVATED CONVECTION.
SO A FEW THUNDERSTORMS THIS WEEKEND ARE POSSIBLE. TEMPERATURES THIS MORNING
ARE NEAR FREEZING ACROSS OUR NORTHERN / BRAZOS VALLEY COUNTIES. COULD NOT
RULE OUT A BRIEF PERIOD OF FREEZING DRIZZLE AND SLEET PELLETS IN THESE AREAS
DURING THE EARLY MORNING HOURS TODAY. HOWEVER, SIGNIFICANT IMPACTS FROM WINTRY
PRECIP ARE UNLIKELY. RAINFALL WILL BE HEAVIEST NEAR THE COAST, WHERE TOTALS OVER
AN INCH ARE LIKELY. RAINFALL RATES SHOULD BE MANAGEABLE.
ONE UNCERTAINTY IN THE FORECAST IS SUNDAY AFTERNOON'S TEMPERATURES. GLOBAL GUIDANCE
SUGGEST MUCH OF THE CWA REACHES THE MID/UPPER 50S. THAT'S STILL COLDER THAN NORMAL
BUT WOULD BE NOTICEABLY WARMER THAN RECENT DAYS. WE ARE GOING WITH LOW/MID 50S FOR NOW.
BUT IT'S NOT OUT OF THE QUESTION THAT WE COULD EEK OUT ONE MORE DAY THAT REMAINS IN THE
40S BEFORE WE ENJOY A WARM UP. FOR MORE DETAILS ON WARMER TEMPS, CHECK OUT THE LONG
TERM DISCUSSION BELOW!
LONG TERM
(MONDAY THROUGH FRIDAY)
ISSUED AT 341 AM CST SAT FEB 22 2025
HELLO, WELCOME TO THE LONG TERM, I HOPE YOU ENJOYED OUR SHORT
REMINDER THAT FEBRUARY IS A WINTER MONTH! REGARDLESS OF WHETHER
YOU ENJOYED IT OR NOT, IT'S PRETTY MUCH DONE FROM THE VERY START
OF THE LONG TERM PORTION OF THE FORECAST. ONCE THE SUN RISES
ENOUGH MONDAY MORNING TO GET TEMPERATURES ABOVE 40 DEGREES, THAT
WILL BE THE LAST TIME WE SEE 30-ANYTHING FOR THE REST OF THE
FORECAST PERIOD.
ZONAL FLOW SETS UP ALOFT PRETTY QUICKLY, WHICH PROBABLY
PRECLUDES THE RETURN OF THE TORCHINESS WE SAW EARLY THIS MONTH,
BUT LOW LEVEL AND SURFACE RIDGING SHOULD SET UP, GIVING US
PERSISTENT ONSHORE FLOW. AT THE VERY LEAST, THAT'S GOING TO GIVE
US A VERY SOLID, HIGH TEMPERATURE FLOOR OVERNIGHT, AND SET US UP
FOR A GRADUAL RETURN TO AFTERNOON HIGHS IN THE 70S. MAYBE NOT
QUITE MONDAY AFTERNOON, BUT DEFINITELY TUESDAY AND WEDNESDAY.
THINGS SHOULD GET CHOPPED DOWN MODESTLY WITH A COLD FRONT VERY
LATE WEDNESDAY NIGHT OR VERY EARLY THURSDAY MORNING. BUT, THE
GENERAL PICTURE IN THE MODEL GUIDANCE IS FOR AN UPPER RIDGE TO
PRETTY QUICKLY BUILD INTO THE FOUR CORNERS REGION, AND SHOULD
SHUNT THE COLDEST OF THE COLD POOL INTO THE GREAT LAKES AND OHIO
VALLEY, WHILE WE JUST GET A BIT OF THE FRINGE. ENOUGH TO MODESTLY
COOL THINGS DOWN, BUT LIKELY ONLY TO SOMETHING AROUND SEASONAL
AVERAGES.
SOME SHOWERS ALONG THIS FRONT ARE...NOT IMPOSSIBLE. IF YOU SQUINT
REALLY HARD, YOU'LL SEE ME BRING POPS FROM NEAR ZERO TO THE 10-15
PERCENT RANGE, WHICH STILL ISN'T ENOUGH TO TRIGGER A SLIGHT
CHANCE OF RAIN IN THE RESULTANT WEATHER FORECAST. IT'S JUST GONNA
BE REAL TOUGH TO GET ANYTHING WITHOUT MUCH OF AN OPPORTUNITY TO
BUILD MOISTURE UP. BOTH THE NAEFS AND EURO ENSEMBLE MEAN
PRECIPITABLE WATER VALUES ONLY GET TO AROUND THREE-QUARTERS OF AN
INCH WHEN THE FRONT COMES THROUGH. PROBABLY ENOUGH THAT I CAN'T
RULE OUT A LIGHT SHOWER SOMEWHERE IN THE AREA ENTIRELY, BUT I'M
NOT GONNA GO ADVERTISING RAIN, EITHER.
IN FACT, THE BETTER CHANCE IS PROBABLY JUST AFTER THE END OF THIS
FORECAST PERIOD, WHEN ONSHORE FLOW RESUMES AND WE GET GULF AIR
RIDING UP OVER ANY LINGERING FRONTAL SURFACE ALOFT. EVEN
THEN...I'M KINDA STRETCHING FOR A REASON FOR RAIN HERE.
AVIATION
(06Z TAF ISSUANCE)
ISSUED AT 1114 PM CST FRI FEB 21 2025
VFR CIGS CONTINUING, BECOMING MVFR AFTER MIDNIGHT. SHOWERS AND
STORMS WILL MOVE IN FROM THE GULF DURING THE MORNING HOURS AND
RAIN CHANCES WILL INCREASE NEAR THE COAST. SHOWERS AND STORMS WILL
BECOME MORE WIDESPREAD IN COVERAGE AND WILL EXPAND INLAND DURING
THE DAY. WINDS WILL BE OUT OF THE NE AT AROUND 10 KTS INLAND AND
AROUND 15 KTS ALONG THE COAST. VSBYS MAY DETERIORATE DUE TO PATCHY
FOG AND/OR SHOWERS DURING THE DAY TOMORROW.
MARINE
ISSUED AT 341 AM CST SAT FEB 22 2025
ELEVATED WINDS AND ELEVATED SEAS WILL PREVAIL INTO SUNDAY
AFTERNOON AS A COASTAL LOW TRACKS ACROSS THE OFFSHORE UPPER TEXAS
COASTAL WATERS. A SMALL CRAFT ADVISORY IS NOW IN PLACE THROUGH
EARLY SUNDAY MORNING ON MATAGORDA BAY, AND THROUGH SUNDAY
AFTERNOON ON THE GULF WATERS. WINDS WILL BE MORE EAST-
NORTHEASTERLY TO NORTHEASTERLY THROUGH TONIGHT AS THE LOW
APPROACHES, THEN SHIFT TO NORTHERLY ON SUNDAY WHEN THE LOW BEGINS
TO EXIT THE AREA. ALSO LOOK FOR RAIN TO OVERSPREAD THE REGION
THROUGH THE DAY, CONTINUE TONIGHT, AND GRADUALLY TAPER OFF FROM
WEST TO EAST ON SUNDAY.
A LIGHT ONSHORE FLOW RESUMES LATE MONDAY. WE'LL CONTINUE TO
MONITOR THE POTENTIAL FOR SOME PERIODS OF SEA FOG LATE TUESDAY
INTO WEDNESDAY NIGHT UNTIL THE NEXT FRONT PUSHES OFF THE COAST.
THE MAIN CONCERN WILL BE HOW COLD THE WATERS OF THE BAYS AND
NEARSHORE GULF WATERS REMAIN INTO MID-WEEK, ALONG WITH HOW WARM
AND HUMID THE AIR ABOVE THOSE WATERS ARE ABLE TO GET.
ADDITIONALLY, WINDS DO LOOK TO VEER A LITTLE MORE SOUTHERLY THAN
TYPICALLY OCCURS WITH SIGNIFICANT FOG EVENTS. ULTIMATELY, THE
COASTAL DEWPOINTS, WATER TEMPERATURES, AND WIND DIRECTION WILL BE
IMPORTANT FORECAST FEATURES TO MONITOR INTO THE NEW WEEK.
CLIMATE
