2 inch range. This deep moisture combined with the passage of a frontal boundary that extended along the coast and continued to move offshore during the early morning hours produced periods of heavy rainfall across South Texas.

The episode as NWS CRP wrote it up.
The atmosphere on September 7th remained well saturated, with PWAT values into the 1.9 to 2.2 inch range. This deep moisture combined with the passage of a frontal boundary that extended along the coast and continued to move offshore during the early morning hours produced periods of heavy rainfall across South Texas. This was particularly true along the Rio Grande. As the day progressed, moisture convergence, daytime heating, and subtle impulses of energy embedded in the northwest flow aloft were enough to support training thunderstorms across the Victoria Crossroads, leading to isolated flash flooding.

NWS Corpus Christi, TX wrote its last area forecast discussion before the first event at Sep 7, 5:24 AM CST, 1 hour 45 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Corpus Christi TX 624 AM CDT Sun Sep 7 2025 ...New AVIATION... .KEY MESSAGES... Updated at 621 AM CDT Sun Sep 7 2025 - Marginal Risk (level 1 of 4) of flash flooding today - Minor to Moderate Heat Risk for the next several days && .DISCUSSION... Issued at 1222 AM CDT Sun Sep 7 2025 Most of the overnight activity thus far has remain in the western Brush Country and along the Rio Grande Plains. Storm motions have been slow (00Z KCRP sfc-6km mean wind at 5 kts) allowing showers and thunderstorms to dump 1.5-2.5 inch amounts NW of Laredo. For the remainder of the early morning hours, this upper-level energy will push further east. CAMS have a secondary area of showers and thunderstorms developing between 2-4am CDT generally south of a line from Freer to Corpus Christi. The more aggressive CAMS want to dump 2-4 inches in the strongest storms wherever the develop. Soils can still handle a lot of what may fall, but too high of rainfall rates may lead to brief ponding and nuisance flooding in low-lying/poor drainage areas. We will continue to monitor these trends and latest CAM runs to see if any updates are needed to the forecast. These showers will continue through late-morning before another batch comes in from the northwest in the afternoon (still scattered in coverage). Most shower and rain activity wind down in intensity/coverage after sunset today. With all this in place, WPC still has all of South Texas in a Marginal Risk (level 1 of 4) for Excessive Rainfall today. Monday's will see one last batch of showers and thunderstorms move through the region with highest amounts along the coast. From Tuesday, shower activity generally remains south of a stalled front, keeping low chances (15-25%) of PoPs along the coast and south of the Kingsville area. North of this stalled front, winds will primarily be out of the east/northeast, bringing in slightly drier air. This will keep our temperatures under 100F for highs (with the exception of the northern Brush Country Tuesday and Wednesday due to min RH's dropping to near 30%). Areas in the Victoria Crossroads have the best chance of having low temperatures on Monday and Tuesday night (near 65F). && .AVIATION... (12Z TAFS) Issued at 621 AM CDT Sun Sep 7 2025 TEMPO groups for reduced VIS and CIG associated with thunderstorms remains valid through the period with prevailing groups given VCTS/VCSH given the scattered nature of overall storm coverage. Mix of VFR/MVFR today. Northern terminals are the first to drop of TEMPOs after midnight. && .MARINE... Issued at 1222 AM CDT Sun Sep 7 2025 Northeasterly flow increase from gentle (BF 3) to moderate (BF 4) strength with near 2 ft seas. Similar conditions remain through the forecast period. Chances for showers and thunderstorms have a moderate chance (50-70%) of developing today, and remaining low (around 30% chance) for the remainder for the forecast period. && .PRELIMINARY POINT TEMPS/POPS...
