SHORT TERM
(TONIGHT THROUGH FRIDAY NIGHT)
ISSUED AT 1200 AM CDT FRI AUG 7 2026
THE SUBTROPICAL RIDGE IS CENTERED NEAR THE FOUR CORNERS REGION THIS
EVENING WITH WEAK ANTICYCLONIC FLOW OVER TEXAS. HIGH PRESSURE OVER
THE GULF IS PRODUCING SOUTHEASTERLY FLOW IN THE LOW LEVELS. THE
AIRMASS OVER SOUTH-CENTRAL TEXAS REMAINS HOT AND MOIST. IN THE SHORT
TERM THERE WON'T BE ANY SIGNIFICANT CHANGE IN THE PATTERN. EXPECT
ANOTHER HOT AND MAINLY DRY DAY WITH HIGH TEMPERATURES ABOUT THE SAME
AS THURSDAY. THE COMBINATION OF HEAT AND HUMIDITY MAY BRING A FEW
SPOTS OVER THE COASTAL PLAINS TO HEAT ADVISORY LEVELS FOR A COUPLE
OF HOURS, BUT WE DON'T EXPECT ENOUGH COVERAGE TO ISSUE AN ADVISORY.
THE UPPER RIDGE WILL BE WEAK ENOUGH TO ALLOW ISOLATED SHOWERS AND
THUNDERSTORMS TO FORM OVER THE COASTAL PLAINS AND MOVE INLAND.
THURSDAY AFTERNOON WE SAW STORMS MOVE TO THE I-35 CORRIDOR, BUT IT
LOOKS LIKE THEY WON'T MAKE IT THAT FAR INLAND TODAY. SATURDAY WILL
BE ANOTHER REPEAT. HOT, MAINLY DRY WITH ISOLATED SHOWERS AND
THUNDERSTORMS MOVING INLAND FROM THE COASTAL PLAINS. STORMS COULD
REACH I-35 AGAIN.
LONG TERM
(SATURDAY THROUGH NEXT THURSDAY)
ISSUED AT 1200 AM CDT FRI AUG 7 2026
SUNDAY AND MONDAY THE STAGNANT PATTERN WILL CONTINUE. HIGH
TEMPERATURES WILL STAY HOT AND NEAR NORMAL BOTH DAYS. HUMIDITY WILL
REMAIN LOW ENOUGH TO KEEP HEAT INDICES BELOW HEAT ADVISORY CRITERIA,
HOWEVER A FEW SPOTS IN THE COASTAL PLAINS COULD BRIEFLY REACH
CRITERIA EACH AFTERNOON. A FEW SHOWERS OR THUNDERSTORMS COULD MOVE
OVER THE COASTAL PLAINS EACH AFTERNOON. AS THE RIDGE SHIFTS BACK
TOWARD THE SOUTHEAST, RAIN CHANCES WILL COME TO AN END TUESDAY.
TEMPERATURES WILL CREEP UP A BIT INTO THE MIDDLE OF NEXT WEEK. THE
HIGHER TEMPERATURES COMBINED WITH THE HUMIDITY MAY PRODUCE HEAT
ADVISORY CRITERIA ACROSS THE AREA SOUTH OF I-10 AND EAST OF I-37.
