Ponding on roadways and street flooding will be possible. - Rain chances will decrease as we near the end of the work week. - Hot weather returns this weekend into early next week with highs in the 90s and heat indicies in the lower 100s. && .DISCUSSION... Issued at 1126 AM CDT Tue Jul 14 2026 Numerous to widespread chances of showers and isolated thunderstorms will continue through early this evening as a boundary lingers over Southeast TX. With local PWs still ranging around 2.0 inches, some showers could produce locally heavy rainfall with rain rate of 2-3 inches per hour at times. The potential for minor flooding will decrease tonight as rain chances decrease, but expect some ponding of water to persists overnight over locations that had good amounts of rainfall today. One good thing about all the rain and increased cloud coverage is that the highs are expected to peak in the lower to mid 80s for many locations today. It will remain rather warm and muggy though for tonight, with lows expected to range in the lower to mid 70s for much of the inland areas. Isolated showers are possible during the overnight hours. For Wednesday, we will once again see a few rounds of showers and thunderstorms throughout the day. Coverage should be less than today's but given that soils are pretty saturated from all the rainfall received in the previous days, it wont take much for minor flooding issues to occur in areas of heavy rainfall. WPC has a Slight Risk (level 2 of 4) of excessive rainfall for much of Southeast Texas for Wednesday. Make sure to have multiple ways of receiving weather updates and warnings and check road conditions before departing to your destination. Never cross flooded areas and heed all road closures. Temperatures will be slightly warmer on Wednesday with highs peaking in the mid to upper 80s. Similar conditions are expected on Thursday, with the higher rain chances focused mainly over areas west of I-45 (in particular, over the Brazos Valley region). Conditions are expected to be drier on Friday and continue into early next week as surface high pressure moves over the region. We will also have the typical summer temperatures return by this weekend with highs ranging in the lower to mid 90s by Friday or Saturday along with heat indices in the lower 100s. Cotto && .AVIATION... (12Z TAF Issuance) Issued at 617 AM CDT Tue Jul 14 2026 SHRA/TSRA will affect all terminals through the next 4-6 hours. Within the TSRA, IFR/MVFR cigs are likely for the northern terminals (from IAH/DWH northward) with VFR cigs south. Occasionally, LIFR cigs have been observed at a few sites, but this should cease after 12z. After 17z, most of the TSRA will transition to SHRA, then end around 21z at all sites. VFR conditions are expected thereafter, except for CLL where some MVFR cigs sneak in toward the end of the period. For IAH, some TSRA may redevelop after 15z, but more likely after 18z Wednesday. && .MARINE...
