SHORT TERM
(TONIGHT THROUGH TUESDAY NIGHT)
ISSUED AT 1234 PM CDT MON JUN 22 2026
THE SUBTROPICAL RIDGE IS BUILDING BACK OVER TEXAS AND WILL
CONTINUE TO DO SO THROUGH THE SHORT TERM PERIOD. THE LOW LEVEL
FLOW IS FROM THE SOUTHEAST ACROSS SOUTH-CENTRAL TEXAS. THE
AIRMASS OVER OUR CWA REMAINS WARM AND MOIST WITH TEMPERATURES AND
DEWPOINTS WITHIN A COUPLE OF DEGREES OF WHERE THEY WERE 24 HOURS
AGO. AS THE SUBTROPICAL RIDGE STRENGTHENS OVER THE NEXT 24 HOURS
THE LOW LEVEL FLOW WILL CONTINUE FROM THE SOUTHEAST. THE UPPER
RIDGE WILL SUPPRESS ANY CONVECTION. TEMPERATURES WILL BE STEADY
THROUGH THE SHORT TERM. LOWS TUESDAY AND WEDNESDAY WILL BE ABOUT
THE SAME AS THIS MORNING. HIGHS TUESDAY WILL ALSO BE ABOUT THE
SAME AS TODAY. WE EXPECT SOME BETTER VERTICAL MIXING OF THE
BOUNDARY LAYER TUESDAY BRING LOWER DEWPOINTS DOWN TO THE SURFACE
WHICH WILL KEEP THE HEAT INDICES LOWER. FOR MOST OF THE AREA THE
HEAT INDEX WILL STAY BELOW 105.
LONG TERM
(WEDNESDAY THROUGH NEXT MONDAY)
ISSUED AT 1234 PM CDT MON JUN 22 2026
THE SUBTROPICAL RIDGE WILL CONTINUE TO DOMINATE OVER THE REGION
THROUGH THE REST OF THE WEEK. THE LOW LEVEL FLOW WILL ALSO
CONTINUE FROM THE SOUTHEAST. THERE WILL BE LITTLE CHANGE IN THE
WEATHER THROUGH THE LONG TERM PERIOD. TEMPERATURES WILL BE FAIRLY
STEADY THROUGH THE END OF THE WORK WEEK AND GOOD MIXING WILL KEEP
HEAT INDICES BELOW ADVISORY CRITERIA. THE WEEKEND WILL BRING A
COUPLE OF DEGREES OF WARMING AND SOME PLACES IN THE COASTAL PLAINS
MAY REACH HEAT ADVISORY LEVEL.
