Issued at 1201 AM CDT Mon Sep 15 2025 - Seasonably hot conditions expected through the forecast period. - Isolated shower and thunderstorm activity is possible along the coast through midweek, then better chances of afternoon showers and thunderstorms increases somewhat late week for much of the region. && .DISCUSSION... Issued at 1201 AM CDT Mon Sep 15 2025 Today through Wednesday will be pretty much a copy-and-paste forecast. Most of the region will be rain-free, but PWATs near 1.5" and daytime heating could lead to a few isolated afternoon showers or thunderstorms along the sea breeze. Weak disturbances aloft will approach/pass through eastern Texas beginning Thursday that continues into the weekend. The coverage of the activity will be largely dependent on the strength and location of the passing shortwaves aloft, but just the presence of them nearby will bump up PoPs to around 20-40% each across the area each afternoon beginning Thursday through next weekend. Temperatures will be fairly seasonal through this week with afternoon high temperatures generally in the low to mid 90s (cooler at the coast) and overnight lows in the low to mid 70s (warmer at the coast). Daytime temperatures may cool slightly by the end of the week depending on how much cloud cover/rain coverage we get with the passing weak disturbances. Fowler && .AVIATION... (12Z TAF Issuance) Issued at 517 AM CDT Mon Sep 15 2025 Isolated patchy fog should clear after sunrise. VFR conditions prevailing during the daytime, with light SE/E winds. Isolated showers could develop in the afternoon, though chances are too low to warrant inclusion in the TAF. Variable winds overnight with brief patchy fog possible again Tuesday morning. 03 && .MARINE... Issued at 1201 AM CDT Mon Sep 15 2025 Light to occasionally moderate east to southeasterly flow (sustained 10-15kt, occasional gusts to 20kt) will persist through at least midweek with seas generally between 2-4ft. Isolated showers and storms over the coastal waters will be possible through midweek with better chances towards the end of the week. The persistent onshore flow will lead to higher than normal high tides through at least the start of next week, peaking at around 3.0- 3.5ft above MLLW at times of high tide.
