The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Corpus Christi, TX wrote its last area forecast discussion before the first event at Sep 3, 11:44 AM CST, 2 hours 16 minutes earlier.
Area Forecast Discussion National Weather Service Corpus Christi TX 1244 PM CDT Sat Sep 3 2022 ...New AVIATION... .SHORT TERM... (Today through Sunday) Issued at 419 AM CDT Sat Sep 3 2022 The deterministic models continue to predict the development of an upper level trough/low over the region during the period. The 00z/06z Saturday run of the GFS/NAM valid at 09z Saturday depict PWAT values that are higher than output from both the satellite- based blended PWAT and the NUCAPS sounding PWAT values, along the coast. Nevertheless, expect at least 2 inch PWAT values over the CWA during the period. The upper pattern will be conducive to a quasi-stationary weak frontal boundary over the CWA during the period. The HREF ensemble mean MSLP/surface wind suggest that the boundary will meander near the northern CWA today, then move slightly southward tonight/Sunday. The combination of the foregoing will contribute to scattered to widespread convection today and Sunday. Concur with SPC with regard to a Slight Risk today/Sunday. However, after coordinating with surrounding WFOs, will not issue a FFA at this time. SBCAPE values 2000-2200 J/kg and 0-4-km column warm but less than nearly saturated (NAM deterministic) suggest less than efficient rainfall production. Expect any flash flooding to be isolated/localized. Although swell periods are expected to increase, the WaveWatch has consistently predicted less than 8 second swell periods for today/Sunday. Will maintain a low rip current risk today/Sunday. Per the P-ETSS, minor coastal flooding may occur at some locations along the coast, during the times of high tide, as early as Sunday morning. Maximum Heat Index value around 105F today and 100F Sunday. && .LONG TERM... (Sunday night through next Friday) Issued at 419 AM CDT Sat Sep 3 2022 Key Messages: - Rain chances continue into late next week - Heavy rainfall could lead to localized flooding - South Texas in a slight risk for excessive rainfall Monday (15% chance of rainfall exceeding flash flood guidance within 25 miles of a point). - The Rio Grande Plains and western Brush Country are in a slight risk of excessive rainfall for Tuesday. -Potential for minor coastal flooding and increased risk of rip currents Monday Mid to upper level low pressure will deepen into the state over the latter part of the weekend, bringing favorable upper-level support for showers and thunderstorms. This system, along with copious tropical moisture (PWATs near 2.2-2.4") and a quasi- stationary frontal boundary will contribute to scattered to numerous showers and thunderstorms through the middle of the week next week. Heavy rainfall remains the main concern with the forecast. WPC has included all of South Texas in a slight risk for excessive rainfall for Monday and the Rio Grande Plains/Western Brush Country in a slight risk for excessive rainfall on Tuesday. Flash flooding also remains a concern through mid-week, particularly for low-lying or poor drainage areas, and for areas that have saturated soils from previous rainfall. Daily chances for convection will continue through the end of the forecast period as available moisture remains high and another disturbance approaches the area. Temperatures through the long-term forecast period will be on the cooler side due to increased cloud cover and rainfall. Minor coastal flooding remains possible Monday and Tuesday as P-ETSS guidance continues to indicate tide levels exceeding 2.0 ft MSL during times of high tide. && .AVIATION... (18Z TAFS) Issued at 1236 PM CDT Sat Sep 3 2022 Periods of showers and thunderstorms are expected through the TAF period. Latest radar shows showers and a few thunderstorms moving west across the Brush Country and Rio Grande Plains with another area of showers across the coastal waters moving toward the coastline. Convective activity is expected to wane this evening, then redevelop overnight into early Sunday morning across the Rio Grande Plains and across the coastal waters and coastal counties, then spread across all of S TX throughout the day Sunday. This will lead to a mix of VFR and MVFR conditions through the TAF period. IFR conditions will also be possible at times with the stronger storms reducing visibilities. VFR CIGs/VSBYs are expected to be generally in the prevailing groups with TEMPO/PROB30 groups carrying the MVFR/IFR conditions. Surface winds will be light to moderate from the east and southeast, but stronger and variable in and around storms. && .MARINE... Issued at 419 AM CDT Sat Sep 3 2022 The combination of copious moisture, a developing upper trough/ low, and a quasi-stationary weak frontal boundary, will contribute to an increasing chance for convection today through Sunday. A generally weak to moderate southeast to east flow will continue through mid next week, along with a daily potential for showers and thunderstorms owing to plentiful available moisture lingering. && .PRELIMINARY POINT TEMPS/POPS...
