KEY MESSAGES
UPDATED AT 559 PM CDT MON OCT 19 2026
- DAYTIME TEMPERATURES WARM INTO THE 80S AND LOW 90S THIS WEEK.
- NO RAIN IS EXPECTED THROUGH THE MAJORITY OF THE FORECAST PERIOD.
SLIGHT CHANCES OF RAIN RETURN FOR AREAS NEAR THE RIO GRANDE AND
EDWARDS PLATEAU BY SUNDAY.
SHORT TERM
(TONIGHT THROUGH TUESDAY NIGHT)
ISSUED AT 123 PM CDT MON OCT 19 2026
CIRRUS AND ALTOSTRATUS CLOUDS HAVE BEEN STREAMING ACROSS THE REGION
THANKS TO WESTERLY AND SOUTHWESTERLY FLOW ALOFT, BUT THIS HAS BEEN
LARGELY UNEVENTFUL AS NEARBY RIDGING ENFORCES DRY CONDITIONS.
KDFX RADAR SHOWS SOME LIGHT RETURNS AT ABOUT 3 KFT AGL WEST OF THE
RIO GRANDE, BUT MUCH OF THIS WILL EVAPORATE IN THE DRY SUBCLOUD
LAYER. THAT SAME RIDGE WILL STAY IN THE AREA THROUGH THE WEEK,
KEEPING RAIN CHANCES OUT OF THE PICTURE DURING THE WORKWEEK.
AMPLE SUNSHINE WILL ALLOW THE LOCAL AIRMASS TO WARM, SO
TEMPERATURES WILL GRADUALLY UPTREND THIS WEEK FROM THE CURRENT
NEAR AVERAGE VALUES TO ABOVE AVERAGE VALUES LATER IN THE WEEK.
HIGHS TODAY WILL RANGE FROM THE UPPER 70S TO MID 80S, AND BROADLY
IN THE MID TO UPPER 80S TOMORROW FOR MOST OF THE AREA. OVERNIGHT
TEMPERATURES SHOULD ALSO TREND UP, BUT DRY CONDITIONS WILL KEEP
NIGHTS COOL AND LOWS NEAR TO SLIGHTLY BELOW AVERAGE FOR MID
OCTOBER IN THE 50S TO LOW 60S TONIGHT AND TOMORROW NIGHT.
LONG TERM
(WEDNESDAY THROUGH NEXT MONDAY)
ISSUED AT 123 PM CDT MON OCT 19 2026
RIDGING STAYS OVER SOUTH CENTRAL TEXAS AND STRENGTHENS MIDWEEK WITH
DRY WEATHER CONTINUING, ALLOWING HIGHS TO INCH A LITTLE HIGHER WITH
MORE OF THE I-35 CORRIDOR, COASTAL PLAINS, AND RIO GRANDE PLAINS
GETTING INTO THE UPPER 80S. THE BULK OF THE HEAT ACCOMPANYING THE
RIDGE SHOULD REMAIN CENTERED OVER NORTHERN MEXICO AND WEST TEXAS, SO
HIGHS ARE EXPECTED TO PLATEAU MID TO LATE WEEK. WE WILL GRADUALLY
TRADE OUT LOWS IN THE 50S FOR LOWS IN THE 60S DURING THE WEEK AS
THE RIDGE ENCOURAGES MORE ONSHORE FLOW AND SLIGHTLY HIGHER
MOISTURE.
THE NEXT ATMOSPHERIC OF DISTURBANCE OF INTEREST COMES IN THE FORM OF
A TROUGH PROGRESSING OVER THE WESTERN US THIS WEEKEND. OUR OVERHEAD
RIDGING FAVORS THIS TROUGHING BEING DEFLECTED TO THE NORTH AWAY FROM
THE AREA. THIS IN TURN KEEPS RAIN CHANCES LOW (BELOW 25 PERCENT FOR
MOST AREAS), BUT A FEW ISOLATED RAINS ARE POSSIBLE ALONG THE LOW-
LEVEL RESPONSE TO THE APPROACHING TROUGH, MAINLY ALONG THE RIO
GRANDE AND EDWARDS PLATEAU SUNDAY INTO MONDAY. OTHERWISE, MOST OF
SOUTH CENTRAL TEXAS IS FORECAST TO REMAIN DEVOID OF RAID FOR THE
NEXT SEVEN DAYS. DAYTIME TEMPERATURES THIS UPCOMING WEEKEND ARE VERY
LIKELY (ABOVE 90%) TO REMAIN ABOVE 80F. LOWS SHOULD CONTINUE TO BE
IN THE UPEPR 50S TO MID 60S.
