| Area Forecast Discussion National Weather Service Houston/Galveston TX 659am CDT Sunday July 19 2026 Issued at 1219am CDT Sunday July 19 2026 Ridging, both at the surface and aloft will dominate area weather this week. Today through Tuesday, a dry column of air should remain in place (PW's < 1.5"). This should allow dewpoints to mix out each afternoon and keep RH's and heat indexes in check. That said, with surface high pressure situated in the northwest Gulf, we should start out most days with low level sw winds which will allow temps to heat up fairly quickly - into the mid 90s again today then 95-100F during the work week. It appears that a portion of the mid level trough.iness across the eastern Gulf breaks off and slides under the ridge toward the western Gulf Coast toward midweek. Most deterministic data suggests this axis should be suppressed offshore and along the mid Tx-Mexico coast, but it should bring some higher moisture levels along the northern periphery here locally. It's still worth keeping up with the latest NHC thinking with this area of unsettled weather considering there remains a subset of AI/TC/ensemble guidance suggesting some potential for development. Right now, however, one of the main concerns here in SE Tx looks to be the increased heat indices as PW's/RH's increase Wed-Friday. There may be a non-zero rain chance during this period, though most of us probably won't see anything of significance considering the subsidence aloft. Heading into the weekend, the mid level ridge to our north further strengthens and H5 heigheights increase to 594-597dm in our region. So the heat doesn't appear to be leaving us anytime soon. 47 Marine Issued at 1219am CDT Sunday July 19 2026 Favorable marine conditions are anticipated into midweek. Surface high pressure will be situated across the northwest Gulf. Southwest winds late at night and in the mornings should become more southerly in the afternoon and evenings as the seabreeze pushes inland. Speeds will generally be in the 8-15kt range...highest at night in the Gulf, and in the afternoons and evenings in the bays. 47 NOAA Houston/Galveston TX Office: Watches - Warnings - Advisories TX...None. GM...None. |
