a tightening pressure gradient between high pressure to our east and lower pressure to our west will lead to moderate onshore winds, building seas and above normal tides through midweek. Expect periods of caution flag and/or advisory level conditions through midweek. Chances for showers and storms return later Friday into Saturday as a weak front sags toward the coast.

Area Forecast Discussion National Weather Service Houston/Galveston TX Issued by National Weather Service Corpus Christi TX 605 AM CDT Wed Apr 30 2025
New AVIATION
SHORT TERM
(Today through Thursday Night)
Issued at 233 AM CDT Wed Apr 30 2025
Today will be more active weather-wise, courtesy of a mid/upper level trough pushing east across the Southern Plains/Desert Southwest. Deep moisture coinciding with a 20-30 knot LLJ over the area should initially bring some WAA showers over our western counties, spreading eastward throughout the day. Isolated thunderstorms become more feasible throughout the afternoon as we reach peak heating, though short-range model guidance has trended toward lower activity during this afternoon period. Still, this environment features ample instability with SFC CAPE around 2000- 2700 J/KG and CIN values over -10 J/KG. 0-6km wind shear around 30- 40 knots should provide sufficient organization necessary to produce stronger storms. Forecast soundings indicate higher precipitation efficiency as we often see here in SE Texas, suggesting the potential for stronger downpours. While instability will wane this evening, high-resolution models continue to show a stronger, more organized line of thunderstorms reaching SE Texas not long after midnight, reaching as far south as Galveston Bay before dissipating Thursday morning. The HRRR continues to depict a more potent solution compared to other model guidance, though notably it was first to pick up on this organized line yesterday, with rather consistent outputs between model runs.
For both today and Thursday, SPC has a Marginal to Slight Risk (levels 1/5 to 2/5) of severe weather, with WPC placing a Marginal to Slight Risk (levels 1/4 to 2/4) of excessive rainfall over much of the same area, especially further north over the Brazos Valley/Piney Wood area. All severe/rainfall hazards are on the table for today through this evening, with damaging winds and locally heavy rainfall becoming the primary concerns overnight into Thursday as the convective line pushes south.
There should be a lull in rainfall from the mid morning to the early afternoon on Thursday with another round of showers/storms from the late afternoon through late Thursday night. Much of this activity should be concentrated north of the I-10 corridor. The risk of severe weather & excessive rainfall should be trending downwards throughout this time frame as the aforementioned trough departs to the northeast.

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.
