CURRENTLY, WE HAVE BROAD UPPER LEVEL RIDGING ALOFT, WITH EMBEDDED
WEAK CONVECTIVELY INDUCED LOWS TRAPPED WITHIN THE RIDGE, ALONG
WITH MID AND UPPER LEVEL CLOUD DEBRIS FROM EARLIER CONVECTION.
WITH THE RIDGE IN PLACE, AND NO OBVIOUS BOUNDARIES AVAILABLE FOR
CONVECTION TODAY, EXPECT TO SEE DRY WEATHER, AND WARM TEMPERATURES
AGAIN. HIGHS SHOULD BE IN THE LOW TO MID 90S, WITH LOWS TONIGHT IN
THE MID 70S. WINDS WILL CONTINUE TO BE OUT OF THE SOUTH AND
SOUTHEAST AT 10 TO 20 MPH.
LONG TERM
(SUNDAY THROUGH FRIDAY)
ISSUED AT 1215 AM CDT SAT JUN 13 2026
A TEMPORARY SHIFT IN THE PATTERN IS EXPECTED TO BRING INCREASED RAIN
CHANCES AND COOLER TEMPERATURES FOR THE FIRST PART OF NEXT WEEK.
WITH AN UPPER RIDGE BUILDING OVER THE EASTERN PACIFIC AND A BROAD
UPPER TROUGH OVER THE GREAT PLAINS, MIDWEST AND GREAT LAKES, THE
RIDGE OVER TEXAS WILL BE SUPPRESSED TO THE SOUTH. WITH THIS SETUP A
COLD FRONT WILL MOVE SOUTH INTO THE BIG COUNTRY BY SUNDAY AFTERNOON,
AND MAY REACH I-20 BY EVENING. THE FRONT IS FORECAST TO CONTINUE
MOVING SOUTH SUNDAY NIGHT AND SHOULD JUST SOUTH OF OUR FORECAST AREA
BY 7 AM MONDAY. THE BETTER CHANCE OF SHOWERS AND THUNDERSTORMS WILL
BE ALONG AND BEHIND THIS FRONT AS IT PROGRESSES SOUTH. WITH A BRIEF
PERIOD OF NORTHWEST FLOW ALOFT, AN EMBEDDED DISTURBANCE IS PROGGED
TO MOVE SOUTHEAST ACROSS OUR AREA LATE SUNDAY NIGHT INTO MONDAY.
THIS COULD BRING ADDITIONAL SHOWERS AND STORMS, WITH THE HIGHER RAIN
CHANCES SHIFTING INTO OUR SOUTHERN COUNTIES MONDAY AFTERNOON. A
RATHER MOIST AIRMASS IS PROGGED WITH PRECIPITABLE WATER VALUES
MOSTLY IN THE RANGE OF 1.6 TO 2.1 INCHES SUNDAY INTO MONDAY. THIS
WILL BE SUPPORTIVE OF HEAVY RAINFALL, AND SLOW-MOVING OR TRAINING
CONVECTION WOULD BRING A POTENTIAL FOR FLOODING. TEMPERATURES WILL
BE COOLER ON MONDAY BEHIND THE FRONT WITH CONSIDERABLE CLOUD COVER.
HIGHS MONDAY ARE EXPECTED TO BE LIMITED TO THE UPPER 70S TO LOWER
80S. A FEW LINGERING SHOWERS AND STORMS WILL BE POSSIBLE INTO
TUESDAY MORNING FOR THE FAR SOUTHEASTERN PART OF OUR AREA.
THE HOTTEST TEMPERATURES SO FAR THIS SEASON WILL BE POSSIBLE
WEDNESDAY INTO LATE WEEK, WHEN A RIDGE ALOFT OVER THE SOUTHWESTERN
STATES IS PROGGED TO SHIFT EAST ACROSS TEXAS. HIGHS ARE FORECAST TO
BE 100-105 DEGREES WEDNESDAY IN PORTIONS OF THE BIG COUNTRY AND
CONCHO VALLEY. FORECAST HIGHS THURSDAY GENERALLY RANGE FROM 100-103
IN MOST OF THE SOUTHEAST HALF OF OUR AREA, TO 104-106 ACROSS THE
NORTHWEST HALF. WITH RELATIVELY HUMID CONDITIONS EXPECTED, HEAT
INDICES WILL BE PUSHING 105-110 ON THURSDAY AFTERNOON. ANTICIPATE
THAT THIS WILL BRING THE NEED FOR HEAT HEADLINES (HEAT
ADVISORY/EXCESSIVE HEAT WARNING). THE DETAILS IN THE FORECAST
THURSDAY NIGHT AND FRIDAY BECOME MORE UNCERTAIN, HOWEVER. SOME OF
THE MEDIUM RANGE MODELS ARE BRINGING A DISTURBANCE NORTH INTO TEXAS
FROM EASTERN MEXICO, AND HAVING THE DISTURBANCE STALL OVER CENTRAL
TEXAS AND BRING A LOW CHANCE (20-30 PERCENT) OF SHOWERS AND
THUNDERSTORMS TO OUR AREA.
