DISCUSSION
ISSUED AT 1107 AM CST THU JAN 1 2026
TEMPERATURES ARE EXPECTED TO CONTINUE WARMING THROUGH SATURDAY, AS
MID-TO-UPPER LEVEL RIDGING REMAINS DOMINANT OVER DEEP SOUTH TEXAS
WITH CLEAR TO PARTLY CLOUDY SKIES AND LIGHT TO MODERATE WINDS.
TOMORROW'S HIGHS SHOULD REACH THE UPPER 80S, AND SOME AREAS WEST OF
I-69C/US 281 COULD SEE TEMPERATURES GET AS HIGH AS THE LOWER 90S ON
SATURDAY. LOW TEMPERATURES SHOULD GET DOWN INTO THE MID TO UPPER 50S
FOR THE WESTERN AND NORTHERN RANCHLANDS AND THE LOWER 60S FOR THE
LOWER RIO GRANDE VALLEY THE NEXT FEW NIGHTS.
CONFIDENCE IS INCREASING THAT A WEAK COLD FRONT MAY PASS THROUGH
DEEP SOUTH TEXAS SATURDAY NIGHT INTO SUNDAY, ASSOCIATED WITH A SMALL
UPPER-LEVEL SHORTWAVE THAT IS EXPECTED TO MOVE OVER THE SOUTHERN
PLAINS THIS WEEKEND. THIS FRONT IS NOT EXPECTED TO BRING ANY
PRECIPITATION TO THE AREA. HOWEVER, HIGH TEMPERATURES COULD BE
AROUND 7-10 DEGREES COOLER FOR SUNDAY THAN SATURDAY, BEFORE
TEMPERATURES BEGIN WARMING TO THE MID-80S AGAIN FOR MONDAY.
HUMIDITY COULD ALSO BE A BIT LESS ON SUNDAY AS WELL, DUE TO THE
NORTHERLY WIND DIRECTION CHANGE, WHICH IS ONLY EXPECTED TO LAST
THROUGHOUT THE DAY ON SUNDAY BEFORE WINDS VEER BACK TO THE SOUTH
AGAIN. ONCE TEMPERATURES WARM FROM THE UPPER 70S/LOW 80S ON
SUNDAY, THEY SHOULD STAY IN THE MID-80S THROUGH THE MIDDLE OF NEXT
WEEK.
NO RAIN IS EXPECTED FOR THE AREA OVER THE NEXT WEEK, BUT
THERE IS A CONTINUED CHANCE OF LIGHT PATCHY FOG DEVELOPMENT IN THE
LATE OVERNIGHT/EARLY MORNING HOURS FOR THE NEXT SEVERAL NIGHTS.
MOTORISTS WILL WANT TO EXERCISE CAUTION IF THEY HAPPEN TO
ENCOUNTER ANY ISOLATED AREAS OF HEAVIER FOG. THERE IS ALSO A
MODERATE RISK OF LIFE-THREATENING RIP CURRENTS AT AREA BEACHES
TONIGHT DUE TO SLIGHTLY INCREASED OVERNIGHT WIND SPEEDS OFFSHORE.

(00Z TAFS)
ISSUED AT 513 PM CST THU JAN 1 2026
GENERALLY VFR CONDITIONS WILL DOMINATE THROUGH THE TAF CYCLE AT
ALL TAF SITES. HOWEVER, AROUND SUNRISE TOMORROW HRL AND MFE COULD
SEE SOME IMPACTS FROM FOG AND LOW-LEVEL CLOUDS THAT WILL REDUCE
CONDITIONS TO MVFR OR IFR. THESE IMPACTS ARE EXPECTED TO LAST ONLY
FOR A FEW HOURS AT THIS TIME. IT IS ALSO POSSIBLE FOR BRO TO SEE
SOME FOG AS WELL, HOWEVER GIVEN THE UNCERTAINTY AT THIS TIME WITH
THE FORECAST AND THE LEVEL OF CONFIDENCE, FOG HAS BEEN LEFT OUT OF
THE TAFS FOR BRO AT THIS POINT. OUTSIDE OF THAT, WINDS ARE
GENERALLY EXPECTED TO BE OUT OF THE SOUTHEAST WITH SOME GUSTY
WINDS PICKING UP TO AROUND 20 KNOTS LATE IN THE MORNING AND LAST
THROUGH THE EARLY EVENING HOURS.
MARINE
ISSUED AT 1107 AM CST THU JAN 1 2026
WINDS COULD REACH SMALL CRAFT EXERCISE CAUTION CONDITIONS ON THE
GULF WATERS TONIGHT AND POSSIBLY CONTINUE INTO TOMORROW MORNING
DUE TO ELEVATED WINDS OFFSHORE. CONDITIONS ARE THEN EXPECTED TO
IMPROVE TO FAVORABLE FOR THE REMAINDER OF THE WEEKEND INTO NEXT
WEEK.
