| Area Forecast Discussion National Weather Service Houston/Galveston TX 113pm CDT Wednesday Oct 7 2026 Issued at 109pm CDT Wednesday Oct 7 2026 Modestly calm & drier weather is still slated to continue this afternoon as east-northeasterly flow remains in place across the region. PWs have gradually declined from yesterday, with Satellite derived TPW showing values of ~1.0 inch near College Station and ~1.7 inches at the coastline. A few shortwaves are forecast pass overhead today following the troughing aloft, though capping around 800-750mb should inhibit development to some degree. Some showers could form under the cap, though most activity will likely be limited to coastal areas, where moisture is deeper. Some showers have already developed along the coast this morning within a small area of convergence, so additional activity isn't completely out of the question. Thursday will generally feature similar weather to that of today, though with some pattern changes. Upper level troughing over the state should deepen while Isaias reaches Hurricane strength and turns northward. The combination of these features should funnel a slot of drier air into SE Texas in the afternoon, keeping inland rain chances isolated over the coast and slim to none inland. As Isaias intensifies, the pressure gradient should also tighten as well, resulting in breezy conditions inland during the afternoon hours. With distant tropical systems, hazardous marine conditions will develop across the Texas Coastal waters, including elevated seas, increased risk of rip currents and potential for minor coastal flooding along Gulf-facing beaches. By Friday, Isaias should be around the central/north-central Gulf, continuing north-northeastward throughout the day. Isaias will have larger influence on the low level-surface flow over the area, backing winds further to the northeast. Some models show higher PWs lingering near the coast, so rain chances won't be completely out of the question, though inland areas once again look to remain dry into the weekend. Onshore winds return around Sunday, ushering in WAA (Warm Air Advection - the movement of warm air) & moisture return into next week as ridging builds overtop SE Texas. Rain chances also make a return as well. 03 Marine Issued at 109pm CDT Wednesday Oct 7 2026 Moderate northeasterly winds are expected to increase over the next few days as Tropical Storm Isaias strengthens and becomes a hurricane. Isaias should remain well east of Southeast Texas, making landfall along the north central Gulf coast later this week. However, increasing winds and easterly swells are still anticipated to bring hazardous marine conditions to the Texas Gulf coast. Caution flags remain in effect for the Gulf waters tonight, with Small Craft Advisories taking effect Thursday morning as winds increase to 15-25 kts and seas rise to 6-9 feet. Elevated water levels during times of high tide (above 3.5 ft MLLW) and increased risk of rip currents are also anticipated due to this tropical system. Winds and seas will subside heading into Sunday. There is still some uncertainty with the full strength of the winds on the west side of Isaias. Some model guidance depicts the strongest of these winds occuring further off the coast in the lightering area. Depending on how conditions evolve, the current Small Craft Advisory configuration may need to be refined. 03 NOAA Houston/Galveston TX Office: Watches - Warnings - Advisories TX...None. GM...Small Craft Should Exercise Caution through Thursday morning for GMZ350-355-370-375. Small Craft Advisory from 7am Thursday to 7am CDT Friday for GMZ350-355-370-375. |
