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.
