Marine Weather and Tide Forecast for El Lago, 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.

AVIATION
(06Z TAF Issuance)
Issued at 1145 PM CDT Tue Apr 29 2025

Mainly VFR conditions at the moment...but anticipate MVFR status to fill back in across a good part of the area overnight into Early-mid morning Wed. Houston terminals haven't been seeing longer term BKN ceilings the past few nights, so maintained SCT low level values there most of the time. Iso-sct shra are possible from mid morning to early afternoon in association with a weak disturbance passing through, but not anticipating much of significance with that. Winds will increase again toward mid morning as we get some mixing and some 20-25kt gusts are again possible. We'll need to watch tstm activity to our north late in the day into Wed night. There's a currently above normal uncertainty in regards to whether some of that is able to sag into parts of SE Tx. Models are currently a mixed bag and we'll monitor trends.

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.
