One person died in Las Vegas of heat related causes.
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 May 8, 9:15 PM PST, 2 hours 45 minutes earlier.
Area Forecast Discussion National Weather Service Las Vegas NV 1015 PM PDT Wed May 8 2019 .SYNOPSIS...A low pressure system is expected to elongate and shift westward, eventually lingering off the California coast through the weekend. Periods of shower and thunderstorm activity along with cooler temperatures can be expected with possible heavy rainfall Thursday evening across Southern Nevada and southeastern California. Precip potential lingers through the weekend but conditions will dry out and temperatures will climb by early next week. && .EVENING UPDATE... No changes to the current forecast grids but confidence does continues to increase for the potential for showers and storms tomorrow with heavy rain potential peaking tomorrow evening along and north of the I-15 corridor. Models continue to show an elongated low pressure system evolving through the course of the day tomorrow which will shift over the Sierra tomorrow afternoon and evening and bring the region into favorable southwesterly divergent flow. Later in the evening, 700 mb WAA from the south will create mid level moisture convergence coincident with this favorable divergent flow and could bring in heavy rain and if heavy enough, flash flood concerns. The area of highest concern looks to be areas along and north of the I-15 corridor extending from southwestern Utah to the southern Sierra range. Timing looks to be after 8PM or so. Will pass along these trends to the overnight crew for consideration of possible product issuances but none were made at this time due to continued low confidence in precip potential after 00Z Saturday. .DISCUSSION...Rest of today through Tuesday. Some isolated showers and thunderstorms have begun to pop-up mainly across far eastern Lincoln county and along the AZ Strip this afternoon. Isolated storms should mainly remain confined to the far eastern edges of the CWA through this afternoon where the better instability is (SB CAPE 500 J/kg). Only concern with the small isolated convection would be lightning and gusty winds. Elsewhere, lingering moisture has allowed for some towering cumulus to develop but much of region should remain dry. A more active weather pattern will begin Thursday remaining through the weekend as multiple shortwaves move through the region. The next shortwave will swing through the base of the long wave trough Thursday. This shortwave will elongate and interact with a piece of energy off the SoCal coast, creating a broad area of low pressure by Friday. This slow moving low pressure will eventually close off just off the SoCal coast and move eastward across the northern California Baja. This system will create widespread storm chances through the weekend as it evolves. With multiple days expecting widespread thunderstorm chances and increasing PW's of 0.8-1" flash flooding could become a concern. Focusing on Thursday, models have been consistent in developing a broad band of precip. across southern NV, Inyo County and northern San Bernardino County overnight tomorrow mainly between 03Z-15Z where the best area for ascent sets up. Storm totals of 0.5"-1.00"+ will be possible with this band, creating overnight flooding concerns and morning commute issues. With the dynamic nature of this system, I wouldn't be surprised to see some overnight thunderstorms tomorrow night as well. Some gusty and erratic winds will be possible with the scattered thunderstorm activity tomorrow afternoon. As deeper moisture moves across the region tomorrow evening and we become saturated the gusty wind potentially will decrease a bit but will be present with any strong thunderstorms. Not a whole lot of confidence in the details beyond Friday morning as the evolution of the closed low is still not fully resolved yet. Still expecting scattered showers and thunderstorms each day through the weekend. By Monday, the low should begin to shift to the east, but there will be enough lingering moisture for some scattered activity to develop along the higher terrain Monday and Tuesday afternoons under a broad high-amplitude ridge. && .AVIATION...For McCarran...There appears to be a boundary of stronger winds west and northwest of the air terminal and lighter northeast to east winds north, east and south of the air terminal. Winds are expected to be predominately out of the north and gusty for the next few hours but could occasionally fluctuate to a light northeast to east wind. Winds should relax early this evening becoming variable under 8 kts then increase again out of the northeast with speeds generally around 10 kts. Scattered-to- broken clouds around 12k feet through the TAF period. For the rest of southern Nevada, northwest Arizona and southeast California...Northerly favored winds 8-12 kts gusting up to 25 kts through the afternoon, decreasing this evening, then increasing again late evening as another push of northerly winds pushes south through the area. that will stay in place through the majority of the afternoon. KDAG will see gusty west to southwest winds this evening and overnight, decreasing by daybreak Thursday. Scattered to areas of broken clouds around 10-12k feet through the TAF period. && .SPOTTER INFORMATION STATEMENT...Spotter activation may be required as an unseasonably active pattern takes hold of the region. Thunderstorm chances look greatest Thursday and/or Friday though sporadic activity will linger through the weekend. && DISCUSSION...Kryston AVIATION...Salmen For more forecast information...see us on our webpage: http://weather.gov/lasvegas or follow us on Facebook and Twitter
