| Area Forecast Discussion National Weather Service Houston/Galveston TX 704am CDT Tuesday September 23 2025 Issued at 1222am CDT Tuesday September 23 2025 For today's outlook, I'm going with a perstence-ish forecast, emphasis on the 'ish'. Much like recent days, I suspect the radar to be a little more active than the guidance suggests. But mid/upper ridging appears a little less stout for today. In addition, a surge of very high PWATs (Precipitable Waters) (2"+) is pushing into the coastline this morning. This tells me that rain chances are at least somewhat higher than yesterday (at least near the coast). But it also tells me there's a better chance of locally heavy rainfall, especially in our coastal counties. We'll be watching the radar carefully this morning in case one of these locally heavy showers / storms decides to drop a quick few inches of rainfall. If you don't receive rain today, perhaps you will finally get your chance on Wednesday. The LL atmosphere remains PWAT (Precipitable Water) rich as a deep-layer trough digs southward, providing synoptic lift and gradually increasing shear. Meanwhile, a cold front pushes southward, enhancing LL convergence. The setup appears favorable for scattered to widespread showers and thunderstorms. Parameters are favorable for locally heavy rainfall capable of localized flooding. In addition, conditions appear conditionally favorable for a few stronger thunderstorms capable of a damaging wind gust. So the radar will be worth a watchful eye on Wednesday as well. For areas near the coast, the rain and thunderstorm threat continues into Thursday morning before a much drier air mass sweeps into the region in the front's wake. Temperatures and humidity continue to appear lower during the second half of the week. Perhaps we can muster a few days in the 80s with lows well down into the 60s. Not bad for late September. Should feel better compared to the humid 90s we've seen of late. Self Marine Issued at 1222am CDT Tuesday September 23 2025 Moderate south to southeast winds along with scattered showers and thunderstorms are expected today. On Wednesday, winds will shift southwest ahead of an approaching cold front. The front will bring a better chance of more widespread shower and thunderstorm activity on Wednesday into Thursday morning. A few stronger thunderstorms capable of gusty winds possible. Winds become more northerly in the front's wake on Thursday and Friday. Winds are expected to be moderate to strong at times, possible warranting caution flags.
