The episode as NWS BRO wrote it up.
Repeating bands of tropical rainfall impacted eastern Cameron and southern Willacy County during the daylight hours of July 1, with daily totals, most between 6 AM and 6 PM CST, averaging 3 inches or higher. Two longer-duration bands impacted southeast Cameron County during the late morning and late afternoon, with each producing minor but notable street flooding on South Padre Island and possibly Port Isabel. Total measured and estimated rainfall was 5 to nearly 8 inches, highest between Laguna Vista and just west of Port Isabel.
Across the larger cities of Brownsville and Harlingen, total rainfall for the period was closer to 3-5 inches, with breaks between bands sufficient to keep water to ponding vs. street flooding. A pocket of 5 to 7 inches fell in open fields in southwest Cameron, with no reports received.

Area Forecast Discussion...UPDATED National Weather Service Brownsville TX 557 AM CDT Tue Jul 1 2025 ...New AVIATION... .SHORT TERM... (Tuesday through Wednesday night) Issued at 1020 PM CDT Mon Jun 30 2025 Wet, unsettled conditions continue through the short term. Today, showers are likely (60-80%) with a chance of thunderstorms as moisture continues to surge north into Deep South Texas. The chance for showers decreases to low (20-30%) overnight and through Wednesday. PWAT values of 2.09" from the 00Z sounding indicate plenty of moisture available and may allow for heavy rain rates, which will lead to ponding on roads and poor drainage areas. Moisture/PW will remain greater than the 90th percentile of climatology for the short term. Within thunderstorms, possible hazards include wind gusts up to 40 mph, heavy rainfall, and lightning. High temperatures below normal with highs in the 80s today and up to low 90s Wednesday. The anomalously high moisture leaves apparent temperatures in the 90s to around 100 by midweek. Seasonable low temperatures in the 70s provide little relief. At the local beaches, increased wave heights maintains a Moderate Risk of rip currents. && .LONG TERM... (Thursday through next Tuesday) Issued at 1020 PM CDT Mon Jun 30 2025 Building high pressure over the central US will decrease rain chances from low (10-20%) to almost none into the holiday weekend.

Near normal temperatures in the 90s (approaching 100 in the mid-upper Valley) return for the weekend, with apparent temperatures ranging from 100 to 110 across most of the CWA each afternoon.
