Highs will range from 90 to 97, depending where rain falls, resulting in indices 101 to 107F across the area. - High pressure moves back in Sunday with limited rain chances and hot conditions expected next week. && .DISCUSSION... (Tonight through next Friday) Issued at 1217 AM CDT Sat Sep 12 2026 A short wave is pushing east across the Lower Mississippi Valley early this morning while PWATs of 2" or better remain in place from the Houston metro to the east coast of Florida. Nocturnal convection is expected to get going again through the early morning hours and gradually transition inland during the mid to late morning hours. Storms will be most numerous along the sea breeze once again. As the upper disturbance passes the region today, a slightly drier airmass aloft will move into interior SE TX and Cen LA. While isolated showers and storms are still expected at these locations, coverage will be much lower than point to the south. Apparent temperatures across inland areas may also push to near heat advisory criteria in the afternoon before convection moves in. A ridge aloft begins to rebuild over the area starting Sunday. Scattered storms will remain possible along the sea breeze, but storms will be isolated at best across inland areas. High pressure aloft becomes established for much of next week. This will reduce rain chances across the area, however a few showers or storms will remain possible along the sea breeze. Temperatures will also increase a couple degrees. && .AVIATION... (12Z TAFS) Issued at 630 AM CDT Sat Sep 12 2026 A moist air mass and a weakness aloft will bring about a decent coverage of showers and thunderstorms in the afternoon along the sea breeze. Will have PROB30 for KARA/KLFT to account for this along with VCTS at KLCH/KBPT. Probability is less further inland and at this time will leave the mention of convection out of the KAEX terminal. Away from the convection, light winds and VFR conditions will prevail. 07/Rua && .MARINE... Issued at 1217 AM CDT Sat Sep 12 2026 High pressure will remain stretched from the Atlantic into the deep south through the middle of the coming week. This will keep winds generally light and south to southwest during the period. Seas will also remain low at 3 feet or less into Wednesday. && .FIRE WEATHER... Issued at 1217 AM CDT Sat Sep 12 2026 Humid conditions with elevated rain chances are expected through Sunday. No fire weather concerns are anticipated. Rain chances will decrease into next week, however scattered storms will remain possible along the sea breeze. && .LCH WATCHES/WARNINGS/ADVISORIES... LA...None. TX...None.
