The episode as NWS CRP wrote it up.
A slow moving upper level disturbance interacted with deep moisture over south Texas to produce thunderstorms over the inland Coastal Bend during the early morning hours of the 7th. Thunderstorms producing locally heavy rainfall remained over the inland Coastal Bend for several hours. Rainfall amounts ranged from 4 to 8 inches from north of Alice southwest to near Benavides. This caused flooding of roads near and south of San Diego.

Area Forecast Discussion National Weather Service Corpus Christi TX 409 AM CDT Fri Jul 7 2023 ...New SHORT TERM, LONG TERM, MARINE... .SHORT TERM... (Today through Saturday) Issued at 231 AM CDT Fri Jul 7 2023 A mid to upper level disturbance centered just off the Middle Texas Coastal Waters is combining with plentiful available moisture (PWATs above 2.2") to generate scattered showers with a few embedded thunderstorms across the area early this morning. This activity is expected to persist throughout the rest of the morning hours, before beginning to diminish later this afternoon as the aforementioned disturbance moves away from the region. A few pockets of 1-2" or more of rainfall accumulations will be possible this morning with the heavier downpours, but widespread flooding is not anticipated. Rain chances are forecast to decrease tonight as high pressure begins to build aloft from the west, then isolated to scattered showers and a few thunderstorms return to the forecast on Saturday due to enough leftover moisture. Temperatures today should stay relatively cool, owing to the rainfall and increased cloud cover, with highs generally in the mid 80s to mid 90s range. In turn, heat index values are expected to remain below 105 degrees for most locations today, with only a few areas briefly reaching 105-109 degrees this afternoon. Lows tonight will be in the 70s areawide, but warmer temperatures return on Saturday with highs ranging from the upper 80s along the coast to near 103 over portions of the Brush Country. Heat index values tomorrow are likely to meet Advisory criteria, with most locations experiencing values between 110-114 degrees for a at least a few hours in the afternoon. A Moderate risk for rip currents remains in effect today, but the risk should become low tonight as winds weaken and swell periods decrease to around 6 seconds. The risk should be low on Saturday as well. && .LONG TERM... (Saturday night through next Thursday) Issued at 231 AM CDT Fri Jul 7 2023 Key Message: - Heat Index Values 110-117 for much of next week. High pressure builds back over the region through the long term period, however the center of the ridge will remain west of our area. Temperatures will return to above normal levels while shallow surface moisture remains elevated. Deep moisture levels, however, decrease and will lead to an end of our rain chances for the upcoming week. The warmest days this week look to be mid to late week when 850 temps rise back to the upper 20s celsius west. With surface dewpoints in the upper 70s and lower 80s we'll expect to see heat advisory conditions daily for much of the area. There is potential that excessive heat warnings (heat index 115+) may be necessary at times, especially through the southern Coastal Bend. && .AVIATION... (06Z TAFS) Issued at 1241 AM CDT Fri Jul 7 2023 A mixture of VFR/MVFR conditions is ongoing across area terminals. Conditions are expected to deteriorate to MVFR or potentially IFR levels later this morning as showers with a few embedded thunderstorms return to the forecast. The convective activity today should be less than yesterday, and sites should bounce back to VFR levels in the afternoon. Winds will be light this morning, but becoming breezy during the afternoon. By this evening, winds should be weakening and becoming light again. && .MARINE... Issued at 231 AM CDT Fri Jul 7 2023 Generally weak to moderate south to southeast flow can be expected today through Saturday across the coastal waters. Scattered to numerous showers with a few embedded thunderstorms are expected today, with brief gusty winds, reduced visibility and cloud to surface lightning possible. Another round of showers and a few thunderstorms is in the forecast for Saturday. Onshore flow will remain generally weak to moderate over the coastal waters Sunday through the middle of next week, except for periods of moderate flow over the southern bays and near shore waters in the late afternoon and evening each day. Drier conditions are expected next week as an upper level high pressure system builds into the region. && .PRELIMINARY POINT TEMPS/POPS...
