Marine Weather and Tide Forecast for Kemah, TX

LONG TERM
(Friday through next Tuesday)
Issued at 1145 PM CDT Tue Apr 29 2025

Shower and thunderstorm chances will increase as we head through the day Friday and Friday night as a weak frontal boundary sags into the area and serves as a llvl focusing mechanism. This boundary will probably make it somewhere close to the coast early Saturday morning then stall as the push of high pressure behind it moves off to the east versus south. Locations north of the boundary will see a brief period of cooler & drier wx for the first part of the day Sat, but deeper moisture pooling to its south will begin lifting again as the day wears on. Combined with a somewhat messy quasi-zonal flow, would anticipate the possibility of additional scattered precip to re-develop inland later in the day.

The next West Coast trof will track across CA and toward the Four Corners area Sun-Tue. We'll see some mid level ridging take shape locally in advance which should generally lead to to warmer conditions and lower chances of rainfall.

(12Z TAF Issuance)
Issued at 542 AM CDT Wed Apr 30 2025

MVFR CIGS/Cloud Decks are currently in place across much of SE Texas with light showers filling inland from the coast. Expect broader improvements in CIGS later this morning after sunrise while gusty S/SE winds set in with VFR conditions returning this afternoon. Isolated thunderstorms, some strong to severe, could develop over portions of SE Texas during the afternoon. A brief lull in showers/storm activity is possible during the late afternoon/early evening as daytime heating wanes. A convective line of thunderstorms should push into southeast Texas late tonight through early Thursday morning. Storms along this line may also become strong to severe at times. MVFR CIGS are expected to fill in across the region again during this overnight period.

MARINE
Issued at 1145 PM CDT Tue Apr 29 2025

A somewhat tight pressure gradient between high pressure to our east and lower pressure to our west will lead to moderate onshore winds, 4-7ft seas and above normal tides through midweek. Expect periods of caution flag and/or advisory level conditions with speeds lingering around 20kt +/-5kt into Wed night-Thurs. There will be a high risk of rip currents along area beaches. Water levels will also be running above normal, but generally peak below levels typically seen with coastal flood concerns. Chances for showers and storms return later Friday into Saturday as a weak front sags toward the coast.
