FXUS64 KHGX 111657 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 1157 AM CDT Mon May 11 2026 ...New DISCUSSION, MARINE... .KEY MESSAGES... - Few scattered to isolated showers/storms this afternoon. - Warm and seasonable weather expected throughout the work week. - Isolated rain chances return over the weekend. && .DISCUSSION... Issued at 1155 AM CDT Mon May 11 2026 Water vapor imagery shows a passing shortwave trough moving into SE Texas aloft this afternoon. Modest moisture lingers behind this morning's cold front with PWs around 1.3-1.5 inches. Clearing skies and afternoon heating should provide some destabilization over the next few hours. CAMs have been suggesting some isolated to scattered showers this afternoon, which are already beginning to show on radar. Could see a few thunderstorms too, though these will mostly likely be weaker & more pulse-like in nature as well. Areas generally east of the I-45 corridor can anticipate overall better rain chances through the afternoon, tapering off tonight as high pressure builds over the area. Rest of the forecast remains largely the same. On Tuesday, a mid to upper level ridge will build over the W CONUS/Four Corners region, ushering in a period of benign weather throughout much of the work week. This ridge aloft should shift easterly with time, along with surface high pressure, allowing light onshore winds to return around Tuesday night, though largely sea-landbreeze driven initially. This will allow moisture to rebuild as temperatures rise through mid week. Highs should be in the upper 70s/80s with isolated 90s possible, while lows reach the 60s/70s. Around Thursday, the ridge aloft will weaken slightly as a series of disturbances push in from the west. The ridge axis will shift east of the area by Friday, weakening it's influence over the area. Long range guidance shows some disturbances/impulses streaming over SE Texas Friday & Saturday with the aforementioned ridge amplifying over the SE CONUS Sunday into next week. Could see some showers during this period, though warm weather and isolated rain chances are still anticipated. 03 && .AVIATION...

Breezy north to northeast winds should decrease this afternoon into Tuesday as high pressure slowly builds into the area.
