DISCUSSION
(THIS EVENING THROUGH NEXT THURSDAY)
ISSUED AT 157 PM CDT FRI SEP 4 2026
TODAY WILL BE THE DRIEST DAY WEVE HAD IN A WHILE IN REGARD TO
PWATS, WHICH ARE CURRENTLY SITTING JUST BELOW THE 90TH PERCENTILE.
PWATS WILL INCREASE AGAIN THIS WEEKEND BEFORE DROPPING ONCE MORE
HEADING INTO NEXT WEEK. NEVERTHELESS, SUFFICIENT LINGERING
MOISTURE IN COMBINATION WITH DIURNAL PROCESSES WILL ALLOW FOR
SHOWERS AND THUNDERSTORMS THIS AFTERNOON. COVERAGE WILL BE
ISOLATED TO SCATTERED BEFORE TAPERING OFF DURING THE EARLY
EVENING. A MARGINAL RISK FOR EXCESSIVE RAINFALL ENCOMPASSES NEARLY
THE ENTIRE CWA TODAY THROUGH THE WEEKEND AS A TROPICAL WAVE MOVES
WESTWARD ACROSS THE GULF COAST. BY TOMORROW, PWATS WILL RISE
SHARPLY, APPROACHING THE DAILY MAXIMUM, AS A MOISTURE RICH
AIRMASS MOVES DIRECTLY OVER THE CWA. THIS WILL BE WORTH WATCHING,
AS PORTIONS OF THE CWA, ESPECIALLY SETX, WILL REMAIN SENSITIVE
FOLLOWING THE PREVIOUS ROUNDS OF HEAVY RAINFALL. THE DEEPER PLUME
OF MOISTURE WILL SHIFT EASTWARD SUNDAY, THOUGH A MOISTURE RICH
AIRMASS WILL REMAIN IN PLACE ACROSS THE GULF COAST STATES HEADING
INTO THE UPCOMING WORK WEEK. THIS WILL SUPPORT OUR CONTINUED RUN
OF THE MILL DAILY DIURNAL SHOWERS AND THUNDERSTORMS.
ALOFT, A RIDGE WILL BUILD ACROSS THE SOUTHERN TO CENTRAL PLAINS,
WHILE A STUBBORN WEAKNESS ALOFT REMAINS IN PLACE OVER THE GULF.
THE STRENGTHENING RIDGE SHOULD SUPPRESS SHOWER AND THUNDERSTORM
COVERAGE ACROSS THE NORTHERN HALF OF THE CWA WHILE ALLOWING
TEMPERATURES TO TREND SLIGHTLY HIGHER DURING THE WORK WEEK. HIGH
TEMPERATURES IN THE UPPER 90S COMBINED WITH HIGH HUMIDITY WILL
RESULT IN APPARENT TEMPERATURES APPROACHING HEAT ADVISORY
CRITERIA, WHICH WILL NEED TO BE MONITORED AS WELL. NEVERTHELESS,
HEAT MAY BECOME MORE OF A HAZARD THAN HYDRO HEADING INTO NEXT
WEEK.
