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 Aug 2, 5:00 PM CST, 2 hours 5 minutes earlier.
Area Forecast Discussion National Weather Service Corpus Christi TX 600 PM CDT Sun Aug 2 2020 .DISCUSSION... Updated for 00Z Aviation Discussion. && .AVIATION... VFR conditions are expected through the TAF period. Some isolated showers and thunderstorms are expected through this evening, but these should diminish as we lose the daytime heating. Ceilings and visibilities could become MVFR/IFR in and around any showers or thunderstorms, but have not included a mention of these as confidence is low. With light winds, low level moisture will be sufficient by the early morning hours that shallow patchy fog is possible for ALI and VCT, so have included some MVFR conditions for those sites. VFR conditions are expected to return by mid-morning Monday. && .PREV DISCUSSION... /Issued 337 PM CDT Sun Aug 2 2020/ SHORT TERM (Tonight through Monday Night)... High-res models are still progging isolated convection to develop across portions of the Coastal Plains and Victoria Crossroads later this afternoon. At the moment the activity has remained over EWX and BRO area, but a few of the storms could track into our CWA over the next few hours. Any convective activity that does develops should be short-lived and dissipate quickly after sunset with the loss of daytime heating. Mostly dry conditions are then in store for South Texas tonight through Monday night as an upper level long wave trough continues to exit the region to the east while high pressure builds in from behind. Subsidence from the high and drier air aloft will aid in limiting rain chances through the period, but cannot rule out a stray shower/storm from developing along the sea breeze again on Monday. The combination of residual surface moisture, drier mid levels and light winds overnight may lead to the formation of patchy fog across portions of the Coastal Plains and Victoria Crossroads. The fog should lift by mid Monday morning, but may be possible again Monday night under similar conditions. Near normal temperatures will continue tonight through Monday night, with lows ranging from the mid 70s to the lower 80s, and highs on Monday in the 90s to near 100. Heat indices may once again reach 105-109 briefly Monday afternoon. LONG TERM (Tuesday through Sunday Night)... Mid/Upper level ridge will begin to build from west to east over the region on Tuesday becoming more amplified over the Southern Plains by the end of the week. Subsidence and lower PWATs will limit rain chances until Friday when a slight increase in moisture (2" PWATs) is expected to produce a few sea breeze showers which will persist through the weekend. NBM temperature guidance still looks too cool and thus bumped values up 3+ degrees. Expect summer like heat to return this week with heat indices reaching 105 to 109 for much of the forecast area. A few locations across the Coastal Plains could flirt with Heat Advisory conditions (110+). MARINE... Isolated showers remain possible this evening and again Monday morning. Drier conditions will resume Tuesday as upper ridging expands over the waters. Weak to moderate onshore flow will prevail through the week in between low pressure across West Texas and a high pressure center in the northern Gulf of Mexico. Rain chances return by Friday and continue through the weekend as the upper ridge moves north of the Gulf waters. && .PRELIMINARY POINT TEMPS/POPS...
