NWS Houston/Galveston, TX wrote its last area forecast discussion before the first event at Aug 21, 11:57 AM CST, 4 hours 13 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Houston/Galveston TX 1257 PM CDT Thu Aug 21 2025 ...New DISCUSSION, AVIATION, MARINE... .KEY MESSAGES... Issued at 1204 PM CDT Thu Aug 21 2025 - Increase in shower/storm coverage today through Friday with locally heavy rainfall possible. - Rain chances lower over the weekend, but should rise again next week as another weak boundary approaches the area. && .DISCUSSION... Issued at 1204 PM CDT Thu Aug 21 2025 A weak, diffuse, slow-moving (and even stationary at times) boundary will be progressing southwards through the region through late tomorrow night. This will allow for higher rain chances across SE Texas, however what will ultimately be driving the when and where of thunderstorm development will be daytime heating and mesoscale interactions like boundary collisions. These boundary collisions will be either outflows between the storms themselves, or with the daily sea breeze. The boundary pushing southwards across the region is really only helping by increasing upper-level support for development as weak vort maxes slide across the boundary. While activity will be possible across the area, coverage is still expected to be highest along and south of I-10 where I-10s. High PWATs will lead to the possibility of locally heavy rainfall of up to 1-2" in isolated strong storms. WPC maintains a Marginal Risk (level 1 of 4) of excessive rainfall for today and Friday. Rain chances continue through the weekend, but coverage is expected to be less with activity confined along the coast associated with the sea breeze. Rain chances increase by Tuesday or Wednesday of next week as another boundary approaches from the north with upper-level northwest flow developing. This northwest flow pattern will likely lead to increased thunderstorm chances through the remainder of the week as weak disturbances embedded in the flow pass through the area. Continued summer-time heat will persist with highs generally in the 90s and lows in the 70s. Afternoon heat indices will rise into the triple digits, so be sure to stay hydrated if preforming strenuous outdoor activities. Fowler && .AVIATION... (18Z TAF Issuance) Issued at 1204 PM CDT Thu Aug 21 2025 Though staffing has generally precluded the regular issuance of this 18Z TAF discussion, the upcoming 24-30 hours contains enough nuance that one is needed. What does have more certainty - VFR outside of any TSRA, and also a weak front moving in that will stall out and result in lighter, fairly variable winds and also plenty of opportunities for SHRA/TSRA. What is less certain - timing and location of scattered to numerous cells, making writing them into the TAFs very difficult, even in the initial hours of the cycle! TEMPOs are out, but given bubbling activity already, may need to be amended at any time. Another thing to watch for is potential for a cluster over late night/early morning storms moving NE-SW across the area, roughly 8-13Z. In coordination with CWSU, consider probability isn't quite high enough to merit a PROB30 mention just yet, but it is close. Finally, in the extended at IAH, have a fairly broad window for a TSRA PROB30 tomorrow afternoon that will have to be refined based on how this afternoon and tonight go. && .MARINE... Issued at 1204 PM CDT Thu Aug 21 2025 A weak, diffuse boundary slowly making its way through the area will lead to increased coverage of showers and thunderstorms through Saturday. Light winds and low seas will continue to prevail through the start of next week. Even though this boundary will be moving through the coastal waters over the next couple of days, it is so diffuse that wind directions will still ultimately be decided by the land breeze/sea breeze: offshore in the overnight and morning periods, and onshore in the afternoons and evenings. Locally higher winds and seas, and locally heavy rainfall will be possible with any storms. Fowler && .PRELIMINARY POINT TEMPS/POPS...
