SHORT TERM
(TONIGHT THROUGH MONDAY NIGHT)
ISSUED AT 1259 PM CST SUN JAN 18 2026
A WIDESPREAD FREEZE WAS OBSERVED ACROSS ALL OF SOUTH CENTRAL TEXAS
THIS MORNING WITH LOWS MAINLY IN THE TEENS AND TWENTIES. THE
COLDEST READING OBSERVED WAS 12 DEGREES IN EDWARDS COUNTY, WITH
PLENTY OF TEENS ALSO NOTED ON THE LCRA NETWORK ACROSS THE HILL
COUNTRY.
DRY AIR REMAINS IN PLACE TODAY AS WINDS RETURN TO A MORE
SOUTHWESTERLY DIRECTION. WITH PLENTY OF SUNSHINE, WE STILL EXPECT
DAYTIME HIGHS TO PEAK IN THE UPPER 50S TO LOWER 60S. WINDS WILL
EASE FOR MOST AREAS TONIGHT, BUT WIND SPEEDS WON'T BE AS WEAK AS
WHAT WE SAW THIS MORNING. WITH DECENT RADIATIONAL COOLING, MOST
AREAS CAN EXPECT ANOTHER FREEZE TONIGHT INTO MONDAY MORNING.
OVERNIGHT LOWS WILL RANGE FROM THE MID 20S TO NEAR 35 DEGREES.
AREAS THAT KEEP A SOUTHERLY WIND OVERNIGHT WILL SEE LOWS CLOSER TO
35 DEGREES AND THIS LOOKS TO OCCUR OVER THE HIGHER TERRAIN OF THE
SOUTHERN EDWARDS PLATEAU AND HILL COUNTRY IN ADDITION TO THE URBAN
AREAS OF AUSTIN AND SAN ANTONIO. IN AREAS WHERE THE WINDS
DIMINISH, VALLEYS AND LOW-LYING AREAS, LOWS WILL BE IN THE 20S TO
NEAR 30 DEGREES.
SOUTHERLY WINDS IN ADVANCE OF A COLD FRONT WILL INCREASE ON MONDAY
AND THIS WILL BOOST DAYTIME HIGHS INTO THE LOWER 60S TO NEAR 70
DEGREES. THE COLD FRONT LOOKS TO ENTER THE NORTHERN PORTIONS OF
THE HILL COUNTRY AROUND SUNSET, THE DROP SOUTHWARD THROUGH THE
REMAINDER OF THE REGION MONDAY NIGHT. AS THE FRONT DROPS
SOUTHWARD, WE EXPECT TO SEE AN INCREASE IN CLOUD COVER AS WARM AIR
ADVECTION ABOVE THE SHALLOW, COOL AIR NEAR THE SURFACE INCREASES.
NO PRECIPITATION IS EXPECTED MONDAY NIGHT, BUT LOOK FOR OVERNIGHT
LOWS TO BE WARMER (MID 30S TO MID 40S) DUE TO THE CLOUD COVER.
LONG TERM
(TUESDAY THROUGH NEXT SUNDAY)
ISSUED AT 1259 PM CST SUN JAN 18 2026
THE WARM AIR ADVECTION PATTERN PERSISTS INTO TUESDAY AND WITH
PLENTY OF CLOUDS AND SURFACE HIGH PRESSURE IN PLACE, WE WILL DROP
FORECAST HIGHS BELOW THE NBM AND KEEP MOST AREAS IN THE 50S TO
NEAR 60 DEGREES. WE DO EXPECT TO SEE SOME LOW RAIN CHANCES NEAR
THE RIO GRANDE PLAINS MAINLY DURING THE DAYTIME HOURS. RAIN
CHANCES ARE THEN EXPECTED TO GRADUALLY SPREAD EASTWARD AND
INCREASE FROM THE HILL COUNTRY EASTWARD INTO THE I-35 CORRIDOR AND
COASTAL PLAINS TUESDAY EVENING INTO WEDNESDAY MORNING. WE'VE SEEN
SOME BACK AND FORTH AMONG THE MODELS REGARDING PRECIPITATION
AMOUNTS. AT THIS TIME, WOULD STILL FAVOR THE HIGHER AMOUNTS TO
OCCUR EAST OF THE I-35 CORRIDOR INTO THE COASTAL PLAINS. RAIN
CHANCES LARGELY MOVE EAST OF THE REGION BY EARLY THURSDAY MORNING,
WITH TOTAL RAINFALL AMOUNTS OF A FEW HUNDREDTHS OR LESS OVER THE
HILL COUNTRY, AROUND 0.10" ALONG I-35 TO THE 0.50-0.75" RANGE IN
THE COASTAL PLAINS.
THE LATEST MODELS HAVE BACKED OFF A BIT ON ANOTHER SURGE OF COOLER
AIR ON THURSDAY, SO WE WILL KEEP TEMPERATURE TRENDS FAIRLY FLAT
BETWEEN WEDNESDAY AND THURSDAY. TEMPERATURES DO NUDGE UPWARD TO
ABOVE NORMAL ON FRIDAY AS SOUTHERLY FLOW BRINGS A MORE NOTABLE
INCREASE IN WARMTH AND LOW-LEVEL MOISTURE TO THE REGION. THE
FORECAST FOR THE UPCOMING WEEKEND REMAINS UNCERTAIN WITH THE
OPERATIONAL GFS AND ECMWF SHOWING A MUCH STRONGER FRONT MOVING IN
AS EARLY AS SATURDAY. WE ARE NOTING THE STOUT COOLING TRENDS AMONG
THE AI VERSIONS OF THE ECMWF AND GFS AS WELL. WE WILL KEEP
TEMPERATURES ABOVE NORMAL ON SATURDAY, BUT HAVE TRENDED COLDER
BEGINNING SUNDAY. WE DO HAVE SOME LOW RAIN CHANCES IN THE FORECAST
FROM THE HILL COUNTRY EASTWARD, BUT THERE IS PLENTY OF UNCERTAINTY
IN THE DETAILS AT THIS TIME.
AVIATION
(00Z TAFS)
ISSUED AT 459 PM CST SUN JAN 18 2026
VFR FLIGHT CONDITIONS CONTINUE DURING THE PERIOD. LIGHT AFTERNOON
SOUTHWESTERLY BREEZES ACROSS MOST LOCATIONS SUBSIDE AFTER SUNSET
WITH CONDITIONS BECOMING VARIABLE AND TO NEAR CALM LEVELS. THE
WINDS ALONG THE RIO GRANDE, INCLUDING KDRT, ARE THE EXCEPTION
WHERE WINDS ARE MORE EAST-SOUTHEAST AND SOUTH-SOUTHEASTERLY IN
DIRECTION. MONDAY AFTERNOON WILL SEE WINDS SLIGHTLY PICK UP WHERE
WINDS TURN MOSTLY EAST-SOUTHEASTERLY IN DIRECTION. A WEAK FRONT
ARRIVES NOT LONG AFTER SUNSET MONDAY EVENING, WHICH WILL TURN THE
WINDS MORE EAST-NORTHEASTERLY IN DIRECTION. SKIES REMAIN MOSTLY
TO COMPLETELY CLEAR THROUGH THE DAY ON MONDAY BEFORE THE ARRIVAL
OF SOME MID-LEVEL CLOUDS AHEAD OF AND IN ASSOCIATION WITH THE
WEAK FRONT AFTER SUNSET MONDAY.
FIRE WEATHER
ISSUED AT 1259 PM CST SUN JAN 18 2026
SOUTHWEST WINDS WILL BE OCCASIONALLY GUSTY THIS AFTERNOON ACROSS
THE HILL COUNTRY AND SOUTHERN EDWARDS PLATEAU REGION. WITH GUSTY
WINDS, PLENTY OF DRY AIR AND MODERATE TO HIGH FIRE DANGER, WE
OPTED TO ISSUE A RANGELAND FIRE DANGER STATEMENT UNTIL 6 PM FOR
ELEVATED TO NEAR CRITICAL FIRE WEATHER CONDITIONS. SOUTHEASTERLY
WINDS RETURN TO MOST AREAS ON MONDAY AND THIS WILL HELP HUMIDITY
VALUES TREND UPWARD. ANOTHER COLD FRONT MOVES IN MONDAY NIGHT
INTO TUESDAY LEADING TO A RETURN OF NORTHEASTERLY WINDS. WE DO
EXPECT TO SEE SOME RAIN CHANCES FOR MOST AREAS LATE TUESDAY INTO
WEDNESDAY, WITH WETTING RAINS STILL FAVORED MAINLY EAST OF THE
I-35 CORRIDOR. DRY WEATHER AND A SLOW WARMING TREND ARE CURRENTLY
ANTICIPATED FOR THURSDAY INTO FRIDAY.
