Strong thunderstorms associated with a spoke of energy associated with a broader upper level disturbance moving through Texas moved southeast across the South Texas Brush Country and into the Lower Rio Grande Valley coastal communities during the early morning hours of June 5th. These storms produced strong and gusty winds to 50 mph, causing minor damage in Willacy County.

These storms produced strong and gusty winds to 50 mph, causing minor damage in Willacy County.
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 5, 4:31 AM CST, 2 hours 44 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Brownsville TX 531 AM CDT Mon Jun 5 2017 .DISCUSSION...Updated for latest aviation discussion below. && .AVIATION...The most significant change to the previous suite of TAFs was to add a TEMPO for afternoon convection, which will also have the potential to produce large hail and damaging winds. The timing of the convection at the three major aerodromes was based on the latest run of the HRRR model. Otherwise, veering surface winds continue to be anticipated due to the approach and passage of a surface trough through Deep South Texas and the Rio Grande Valley. Outside of the convection, VFR is anticipated through the next 24 hours. && .PREV DISCUSSION... /issued 357 AM CDT Mon Jun 5 2017/ SHORT TERM (Today through Tuesday): The main concern in the short term portion of the forecast is severe weather. The Storm Prediction Center has placed nearly the entire BRO CWFA is a Marginal to Slight risk of severe weather from sunrise this morning to sunrise Tuesday morning. The generators for this potential severe weather will be closed 500 mb low pressure initially over northeast Texas that will migrate to just offshore central Louisiana during the first 24 hours of the forecast period, a mid-level trough axis extending from this low that will pass through Deep South Texas and the Rio Grande Valley, and a surface trough that will also pass through this region. Therefore, have indicated scattered thunderstorms today and isolated to scattered thunderstorms tonight, with a designation of large hail and damaging winds for these thunderstorms. Isolated convection, non- severe, is possible for the adjacent coastal waters on Tuesday as the closed 500 mb low continues to move east, but inland areas will experience dry weather. Veering surface winds with a downsloping effect off the neighboring higher terrain of Mexico will ensure well above normal daytime high temperatures today and tomorrow. LONG TERM (Tuesday Night through Sunday): Quiet weather which begins on Tuesday as pesky and relatively deep (for June) 500 mb trough exits farther into the Gulf/eastern US as front side of modest 500 mb ridge enters west Texas, bringing a rare shot of fresh northerly surface winds in early June which will bring lower humidity despite the still hot temperatures but slightly more comfortable mornings both Wednesday and Thursday with the drier air in place. By Friday, the eastern trough attempts to retrograde back a bit and ECMWF/GFS each hint at a slug of some moisture rotating back across the eastern half of Texas. Both models show the balance of the moisture to be cirrus with perhaps a few cumulus as well with little effect on the still seasonably hot temperatures by day and warm by evening/overnight. On Saturday, models diverge a bit with ECMWF showing a short wave riding down the front side of the ridge and helping the back-build the 500 mb trough even further. The wave dives into Deep South Texas into Sunday and would bring sufficient lift for isolated convection through the period. GFS on the other hand maintains flat ridge with weaker impulses sliding by well north of the region, keeping things rain-free. The current situation of unsettled weather into early Tuesday (this week) was better handled during the middle of last week by the ECMWF, so there may be some potential for a slightly more pessimistic forecast for next weekend. For now, prefer to see a trend begin before adding any mention of rain into the forecast. The "wetter" ECMWF appears a tad lower with extrapolated surface temperatures next weekend, but given the reality of hotter temperatures that have started June prefer to keep the heat going. For most of the period, this means upper 90s to around 100 west of US 281, low to mid 90s elsewhere and mid to upper 80s at the beach. MARINE: Buoy 42020 reported south winds around 16 knots gusting to around 18 knots with seas slightly under 3.5 feet with a period of 7 seconds at 03 CDT/08 UTC. Mariners will experience light to moderate winds and moderate seas during the period with weak surface low pressure in place over the western and northwest Gulf of Mexico. Of main concern for the mariners will be the potential for scattered severe thunderstorms today and tonight due to a mid- level low pressure system that will shift from Texas to Louisiana. Tuesday Night through Friday: The brief surge of north/northeast winds Wednesday will push up seas/surf a bit especially south of Port Mansfield. Would not be surprised to see a brief period of 5 foot seas into Wednesday evening before conditions subside Thursday with lighter winds. Light winds/slight seas should dominate Friday with surface ridge holding over the Lower Texas Gulf waters. && .BRO WATCHES/WARNINGS/ADVISORIES...None. && This product is also available on the web at: HTTP://WEATHER.GOV/RGV
