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 Las Vegas, NV wrote its last area forecast discussion before the first event at Jun 25, 11:22 PM PST, 38 minutes earlier.
Area Forecast Discussion National Weather Service Las Vegas NV 1222 AM PDT Mon Jun 26 2023 .SYNOPSIS...A series of shortwave troughs will move through the region during the first half of the week resulting in breezy afternoons and evenings. Towards the end of the week, high pressure will build across the area, allowing temperatures to rise to above-normal levels. && .DISCUSSION...through Sunday. Little change in forecast expectations...still expecting this western troughing to continue through the mid week, sending pulses of enhanced vorticity across the Great Basin this evening, and again Tuesday evening. This should keep the area breezy, with our wind prone areas approaching the 40-45 mph threshold, but the majority of the CWA seeing lesser southwest wind gusts. There has been a consistent signal for some showers and isolated thunderstorms in the Esmeralda and northern Nye county areas this afternoon and evening and that continues to be the case. This is due to some meager instability and favorable positioning to this afternoons shortwave. 00Z HREF shows the FV3 being the more bullish CAM in that area, but all members show at least some convection there this afternoon. With the weak forcing and meager instability, not expecting much in the way of robust updrafts, but mostly rooted on high terrain in those areas...and with limited moisture to play with, not expecting heavy rain to be much of a threat. However, 00Z HRRR shows a nearly 400 mb deep inverted V profile at KTPH and resultant 1000 J/KG DCAPE. So biggest concern for Goldfield, Dyer, and Tonopah will be strong outflow winds this afternoon. After tonight, a few more breezy afternoons and high temperatures staying generally constant through Wednesday. By late week and into the weekend, the pattern change over to building heights and ridging over the west is expected, but the speed and manner of this transition is a little less certain. The 12Z cluster analysis shows a bit more variance in the exit of our final shortwave, with the EC mean slowing that exit compared to the GEFS mean. Whichever comes to fruition will likely be responsible for our first 100F at KLAS being either Thursday or Friday. FWIW, the deterministic NBM indeed forecasted 100F for Thursday, but even the NBM gives that percentage chance 37% as of 01Z. A bold strategy, so we will see how it works out for it. Heading into the weekend, the uncertainty in the ensembles is not whether we will have a strong warmup or not, but rather how strong. While Vegas has been focused on the first 100F, the first 110F may not be too far off. Sunday through the 4th of July, highs will have about a 20% of reaching 110F each afternoon at KLAS, and that could put parts of the Valley and especially the Colorado River Valley (and the Lake Mead NRA) in the "major" heat risk category if so. We will be watching this very closely as these recreation areas will be heavily attended for the holidays and proactive headlines may be warranted if the warmer EC trends become the consensus. && .AVIATION...For Harry Reid...Gusty south-southwest winds will return early this afternoon between 18 and 20Z with gust speeds between 25 and 30 kts. Gusts will become isolated after sunset, falling off completely after 06Z. Breezy southwest winds return Tuesday afternoon. No operationally significant cloud cover through the TAF period. For the rest of southern Nevada, southeastern California, and southwestern Arizona...Gusty southwest winds expected to pick up across the region early this afternoon, with gusts between 25 and 35 kts. Gusts will diminish after sunset, with the exception of KDAG, where gusts will prevail overnight. KBIH will become northwesterly after sunset before becoming south-southeasterly on Tuesday. Elsewhere, southwest gusts will return Tuesday afternoon. No operationally significant cloud cover through the TAF period. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && DISCUSSION...TB3 AVIATION...Varian For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
