The episode as NWS BRO wrote it up.
An early morning squall line started in northern Mexico and raced through the Rio Grande Valley on June 8th. A few pockets of thunderstorm wind damage was observed in and around Brownsville. Most ASOS stations recorded winds in the 50 to 55 mph range as it swept towards the coast.
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 Brownsville, TX wrote its last area forecast discussion before the first event at Jun 8, 5:19 AM CST, 31 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Brownsville TX 619 AM CDT Thu Jun 8 2023 ...New AVIATION... .SHORT TERM... (Today through Friday) Issued at 321 AM CDT Thu Jun 8 2023 Infrared satellite imagery currently shows a cluster of thunderstorms straddling the shared border of Texas and the Mexican state of Coahuila. Meanwhile, a composite of various Doppler radars across the Lone Star State shows showers and thunderstorms affecting the western fringes of both the EWX and CRP CWFAs. Per a recent Special Weather Statement issued by the CRP CWFA, this convection is moving towards the southeast at 25 mph. The most recent run of the HRRR model has a decent handle on this mesoscale convective system (MCS), although the position of it in the model for this time is a little too far to the northwest. Regardless, the HRRR moves this MCS into the BRO CWFA before 11 UTC, with gradual weakening until it dissipates somewhere over Kenedy County by 15 UTC. The forthcoming official forecast should reflect the evolution of this convection. Of greater difficulty to determine is what subsequently happens today after the current MCS dissipates. The Storm Prediction Center (SPC) places a majority of the BRO CWFA (basically, the five easternmost counties) in a Marginal Risk of severe weather from around sunrise this morning until around sunrise Friday morning. However, the HRRR is devoid of Deep South Texas/Rio Grande Valley convection after the MCS dissipates, the SPC mentions in their discussion disagreement between the HRRR model and various CAM models, and the official "grids" for the BRO CWFA are dry for this afternoon through Friday afternoon. Given the uncertainty in the forecast for the next 24 hours, and the fact that leftover cirrus debris from the aforementioned MCS may be a significant limiting factor for new convection during that time period, will pass these concerns on to the successive shift and give them time to assess the lingering impacts of the MCS. Temperature-wise, heat begins to build across the BRO CWFA today, but even more so for Friday. Heat index values will range between 100 and 107 degrees today, but between 103 and 110 degrees on Friday. However, heat indices are below established Heat Advisory criteria, and therefore, an Advisory is not anticipated to be needed during the short term forecast period. && .LONG TERM... (Friday night through Wednesday) Issued at 321 AM CDT Thu Jun 8 2023 -Hot weather will likely prompt daily heat advisory conditions. Dry and hot weather will be the main story through the long term period. A midlevel ridge will push east into south Texas. The good news is that this will suppress thunderstorm chances through the period. The bad news is that the heat is on. Temperatures will continue to climb through the weekend into next week. High temperatures will range from the mid 90s across our eastern counties to low 100s across the Rio Grande Plains. As we head into the middle of next week expect uppers 90s to low 100s across the eastern counties and temperatures nearing 110 across the Rio Grande Plains. Couple these high temperatures with the humidity and heat advisory criteria will be attained most afternoons for much of the CWA. && .AVIATION... (12Z TAFS) Issued at 615 AM CDT Thu Jun 8 2023 A ball of convection is advancing on the aerodromes at this time, and the timing of the thunderstorms has been built into the new TAF issuance. Afterwards, VFR will prevail for the remainder of the day and through tonight. && .MARINE... Issued at 321 AM CDT Thu Jun 8 2023 Now through Friday: Buoy 42020 reported south winds around 6 knots gusting to around 8 knots with seas slightly over .5 feet with a period of 3 seconds at 150 CDT/650 UTC. Light to moderate winds and generally low seas will prevail along the Lower Texas Coast during the period courtesy of high pressure centered over the western and northwestern Gulf of Mexico. Small Craft Exercise Caution and Small Craft Advisory are not likely to be needed. Friday night through Monday night: Moderate southeast to south winds and moderate seas. Slightly stronger winds over the weekend will be in the small craft should exercise caution territory. && .PRELIMINARY POINT TEMPS/POPS...
