DISCUSSION
(THIS AFTERNOON THROUGH SUNDAY)
ISSUED AT 1229 PM CDT MON AUG 31 2026
THE REGION REMAINS UNDER THE INFLUENCE OF A LARGE UPPER RIDGE. TO
OUR SOUTH, AN AREA OF LOW PRESSURE OVER THE NORTHERN GULF WILL
CONTINUE TO TRACK WESTWARD OVER THE NEXT COUPLE OF DAYS. THE NHC
HAS ISSUED AN ADVISORY FOR A POTENTIAL TROPICAL CYCLONE, WHICH
MAY STRENGTHEN INTO A TROPICAL STORM TONIGHT AS IT NEARS THE
SOUTHWEST LOUISIANA/UPPER TEXAS COAST. AS WE HEAD THROUGH THE
WORK WEEK, THE UPPER RIDGE WILL EXPAND EASTWARD, STEERING THE
TROPICAL SYSTEM WESTWARD ACROSS THE GULF.
DRIER AIR AND INCREASED SUBSIDENCE WILL MAINTAIN MAINLY RAIN-FREE
CONDITIONS ACROSS THE CENTRAL THIRD OF THE AREA. WE ANTICIPATE
LOW CHANCES FOR DIURNALLY DRIVEN CONVECTION ACROSS OUR SOUTHERN
AREAS WHERE MOISTURE REMAINS ELEVATED. ACROSS THE FAR NORTH,
SPECKLED SHOWERS MAY DEVELOP WITHIN AN OUTER CONVERGENCE ZONE.
WHILE SEVERE WEATHER IS NOT EXPECTED DUE TO MINIMAL WIND SHEAR,
SUFFICIENT INSTABILITY EXISTS TO SUPPORT AN ISOLATED STRONGER
STORM DURING PEAK HEATING.
A WARMING TREND BEGINS THIS WEEK, WITH TEMPERATURES CLIMBING INTO
THE MID-TO-UPPER 90S BY MIDWEEK. HUMID CONDITIONS WILL PUSH HEAT
INDICES TO 105-108° EACH AFTERNOON, LIKELY NECESSITATING DAILY
HEAT ADVISORIES. PROBABILISTIC HEAT RISK DATA INDICATES A 50-60%
CHANCE OF MAJOR OR HIGHER HEAT RISK HEADING INTO LABOR DAY
WEEKEND. WE WILL INCREASE HEAT SAFETY MESSAGING THROUGHOUT THE
WEEK; EMPHASIZE THE IMPORTANCE OF HYDRATION AND LIMITING OUTDOOR
EXPOSURE.
