DISCUSSION
(THIS EVENING THROUGH NEXT THURSDAY)
ISSUED AT 128 PM CDT FRI JUL 24 2026
WX MAP IS FAIRLY QUIET THIS EVENING AS ALL TROPICAL THREATS HAVE
DISSIPATED. BACK TO OUR REGULARLY SCHEDULED HOT LOUISIANA / TEXAS
SUMMER HEAT.
UPPER LEVEL RIDGING BUILDING NEAR THE FOUR CORNERS REGION IS
EXPANDING EAST ALONG THE SOUTHERN PLAINS AND SECONUS. SURFACE
PRESSURE IS NEAR 1020MB AND SUBSIDENCE INVERSION HAS BECOME MORE
EVIDENT ON RECENT 24TH/18Z UPPER AIR ANALYSIS. TEMPERATURES WILL
CLIMB TOWARD THE MID 90'S, DAILY, THROUGH THE WEEKEND. MUGGY
CONDITIONS WILL BE THE NORM DURING MORNINGS AND EVENINGS WHILE
AFTERNOON HUMIDITY RANGES 40-50% THROUGH THE MIDDLE OF NEXT WEEK. AS
THE SUBTROPICAL RIDGE BROADENS THROUGH THE UPCOMING WORK WEEK,
TEMPERATURES ARE FORECAST TO CLIMB FURTHER INTO THE MID OR UPPER
90S. CANNOT RULE POTENTIAL FOR FEW BACKYARDS WITHIN INTERIOR CITIES
AWAY FROM THE COAST TO TOP OUT AROUND 100°F DURING THE EXTENDED
PERIOD. AS INDICATED AT THE TOP OF THE DISCUSSION, THIS PERIOD WILL
BE MAINLY DRY GIVEN POOR LAPSE RATES, DRY MID LEVELS, AND SUBSIDENCE
INVERSIONS. WE START TO SEE A SLIGHT RETURN OF MOISTURE CONVERGENCE
AS A WEAK FRONT DESCENDS ACROSS THE MISSISSIPPI VALLEY, BUT AT THIS
STAGE OF THE FORECAST, EVEN THOSE CHANCES ARE CLOSE TO NEGLIGIBLE
THROUGH THE END OF THE UPCOMING WORK WEEK.
