| Area Forecast Discussion National Weather Service Houston/Galveston TX 1222am CDT Wednesday September 9 2026 Issued at 1221am CDT Wednesday September 9 2026 Elongated, flat mid level ridge currently stretches from the Desert Southwest eastward across the Carolinas. An inverted trough across the western Gulf, along with some trough.iness moving across the ncntl U.S. should carve out a general weakness and split the ridge (to our east/west). This weakness should mostly persist into the weekend, and with a touch less subsidence to overcome, allow for chances of scattered showers/thunderstorms on a daily basis. With lack of significant forcing other than the seabreeze/baybreeze, these will mostly be diurnally driven with highest coverage late at night and mornings offshore transitioning inland during the day after some heating. PW's of 2.0-2.2" across the southern half of the area would suggest the probabilities of the higher coverage being situated there moreso than in the Brazos Valley & Piney s. The eastern portion of the ridge looks to regain its strength and gradually expand back into the region early-mid next week...not eliminating rain chances - but allowing subsidence to put up more of a fight. 47 Marine Issued at 1221am CDT Wednesday September 9 2026 Light onshore flow and low seas will prevail for the next several days, perhaps increasing a touch by the end of the work week as the pressure gradient slightly tightens. The main concern for mariners will be dodging the late night and morning scattered showers and thunderstorms. We had some reports of funnels/waterspouts the past day or two. Environment today is similar, with a light flow regime in place so we wouln't be overly surprised to see a few more reports of these. (Not abnormal in these environments, typically short-lived, and occur in the early and mid morning hours). 47 NOAA Houston/Galveston TX Office: Watches - Warnings - Advisories TX...None. GM...None. |
