DISCUSSION
ISSUED AT 1148 AM CDT SUN SEP 6 2026
WE WILL CONTINUE TO SEE ADDITIONAL SHOWER AND THUNDERSTORM
DEVELOPMENT THIS AFTERNOON AS DIURNAL HEATING AND INSTABILITY
PEAKS. THE GOES-19 TOTAL PRECIPITATION WATER SATELLITE IMAGE AT
11 AM THIS MORNING INDICATED AMOUNTS BETWEEN 2.1-2.4 INCHES; THIS
WILL LEAD TO PERIODS OF HEAVY RAINFALL WITH RAINFALL AMOUNTS OF
2-3 INCHES PER HOUR AT TIMES. PONDING OF WATER AND MINOR FLOODING
IS POSSIBLE IN LOCALIZED AREAS, IN PARTICULAR FOR STORMS WITH
LITTLE MOVEMENT. SHOWERS AND THUNDERSTORMS ARE EXPECTED TO
DISSIPATE THIS EVENING AS DIURNAL HEATING DECREASES AND THE
ENVIRONMENT BECOMES MORE STABLE.
THE HIGH TEMPERATURES THIS AFTERNOON WILL BE IN THE LOW TO MID
90S WITH HEAT INDICES PEAKING BETWEEN 100-107 DEG F. FOR TONIGHT
INTO EARLY MONDAY, WARM AND TRANQUIL CONDITIONS ARE EXPECTED WITH
CALM/LIGHT WINDS AND LOW TEMPERATURES MAINLY IN THE MID TO UPPER
70S INLAND AND THE UPPER 70S TO LOWER 80S ALONG THE COASTS.
LOW LEVEL MOISTURE IS EXPECTED TO LOWER EARLY NEXT WEEK, WITH PWS
FORECAST TO DECREASE TO 1.8-2.1 INCHES ON MONDAY AND 1.7-2.0 ON
TUESDAY. THE MID LEVEL HIGH PRESSURE CURRENTLY OVER THE TEXAS
PANHANDLE WILL SHIFT INTO OKLAHOMA AND MODELS INDICATE INCREASING
DAMS (592-594) OVER SOUTHEAST TEXAS MONDAY INTO TUESDAY. MODELS
ALSO SHOW DRIER AIR ALONG THE MID-LEVELS FOR BOTH DAYS. EVEN WITH
RELATIVELY GOOD MOISTURE AMOUNTS ALONG THE SURFACE, OVERALL RAIN
CHANCES ARE THEREFORE EXPECTED TO BE SLIGHTLY LESS AND GENERALLY
FOCUSED OVER AREAS NEAR AND SOUTH OF I-10 AND THE COASTAL GULF
WATERS. THE AFTERNOON SEABREEZE WILL ALSO CONTRIBUTE TO STORM
DEVELOPMENT.
CHANCE FOR SHOWERS AND THUNDERSTORMS MAY INCREASE AGAIN ON
WEDNESDAY AS ANOTHER SURGE OF MOISTURE MOVES IN FROM THE GULF
WATERS AND INCREASES THE LOCAL PWS TO UP TO AROUND 2.2 INCHES.
LOCALLY HEAVY RAIN MAY BE POSSIBLE. DAILY RAIN CHANCES WILL THEN
CONTINUE INTO THE END OF THE WEEK AS THE HIGH PRESSURE WEAKENS
OVER SOUTHEAST TEXAS (OR SHIFTS AWAY) AND A MID-UPPER LEVEL
DISTURBANCE MOVES THROUGH.
