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 Austin/San Antonio, TX wrote its last area forecast discussion before the first event at Apr 30, 11:39 PM CST, 21 minutes earlier.
Area Forecast Discussion National Weather Service Austin/San Antonio TX 1239 AM CDT Fri May 1 2020 .AVIATION... Dew point temperatures continue to run in the 50s and 50s across South Central Texas and the Texas coast which should result in a night of VFR conditions despite light southerly winds returning overnight tonight. The VFR conditions will continue during the day on Friday. Southerly winds during the afternoon will pick up and be gusty at times anywhere between 20 and 30 knots. With the enhanced southerly flow during the day on Friday, low clouds should be possible by Saturday morning resulting in MVFR ceilings by around 09z Saturday AM. && .PREV DISCUSSION... /ISSUED 242 PM CDT Thu Apr 30 2020/ SHORT TERM (Tonight through Friday Night)... Clear skies and mild overnight low temperatures can be expected across south central Texas tonight. With weak high pressure over east Texas, our surface winds will become southerly across most areas. Lows will be pretty close to climatological normals, with temperatures ranging from the mid 50s to the mid 60s. Gusty south winds will signal a warming trend tomorrow. Shallow moisture in the low-levels will mix out and with plenty of sunshine, we should see highs in the upper 80s to mid 90s. LONG TERM (Saturday through Thursday)... The beginning of May will feel more like the beginning of July. An upper level ridge will move across the Southern Plains over the weekend and early next week while surface high pressure settles over the Gulf. The low level flow will be from the southeast keeping warm, moist air over South Central Texas. Temperatures will warm slowly during this timeframe. High temperatures Saturday will be in the 90s most places with the upper 90s along the Rio Grande. They will increase slightly each day until Tuesday when most places will be middle to upper 90s with triple digits from San Antonio to Del Rio and southward. Wednesday a cold front will bring relief from the heat, but probably no rain. There is some model disagreement on whether this front will produce any precipitation with the GFS being wetter than the ECMWF. The blended guidance is dry and we have used that for now. There will be cooler air behind this boundary and highs Wednesday will be 10 to 15 degrees cooler than Tuesday. && .PRELIMINARY POINT TEMPS/POPS...
