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 Jul 18, 2:54 AM PST, 5 hours 6 minutes earlier.
Area Forecast Discussion National Weather Service Las Vegas NV 354 AM PDT Mon Jul 18 2022 .SYNOPSIS...A final day of monsoonal thunderstorms expected, favoring the higher terrain. Monsoon moisture retreats through the week, dropping precipitation chances for the region. Temperatures will remain above-average until next weekend when monsoonal moisture begins to filter back into the area. && .DISCUSSION...Today through Sunday. Similar to yesterday, a Mesoscale Convective Vortex (MCV) originating from the Sonoran Desert began its approach toward our CWA around sunset. The resultant system reached southern Mohave and San Bernardino counties around midnight, initially producing light (locally moderate) rainfall, frequent lightning, and outflow winds between 35 and 45 mph. That said, very localized severe wind gusts are possible directly underneath or near stronger cells. The Needles, CA ASOS at the Needles Airport gusted to 58 mph at 2:03 AM PDT due to a dropped core overhead. As this system pushes north- northwestward through our region, cells continue to fall and regenerate on and ahead of its associated vorticity advection. Around 3:00 AM, robust development over the Mount Nutt Wilderness (west of Golden Valley) produced notable rainfall rates, resulting in a Flash Flood Warning for western Golden Valley until 5 AM. Rates of 0.30"/15 minutes noted in western Golden Valley neighborhoods directly over the Tennessee Wash, and 0.75"/30 minutes in the mountains of the Mount Nutt Wilderness area over washes that flow into the Tennessee Wash (which flows over numerous roadways in the area). Numerous outflows from the ongoing MCV can be seen on radar. One extending northwestward from the Peach Springs complex has produced gusts between 30 and 35 mph to South Cove at Lake Mead. Meanwhile, ongoing light-to-moderate rain stretches in a band from Ludlow, CA in San Bernardino County, through Laughlin/Bullhead City, into Kingman, AZ in Mohave County. This line will continue to push northward through the early-morning hours, with the HRRR hinting at Las Vegas Valley convection as early as 7 AM. A number of locations in Las Vegas have yet to receive heavy rain so far this year, so light rainfall has the potential to make roadways dangerously slick during the morning commute. Leave 2x the distance between yourself and the car in front of you to ensure you have enough space to stop if your wheels fail to gain traction. Convection through the afternoon today will likely operate similar to yesterday - favoring the higher terrain, with a later onset of convection due to the ongoing MCV working through the bulk of the available convective energy in the area this morning. Best chances for thunderstorm activity will generally remain north of Interstate 40, though an isolated cell south of the interstate is not out of the question. Gusty winds and frequent lightning will be the primary hazards, though localized flooding cannot be ruled out with stronger storms. Moving through the remainder of the work week, monsoonal moisture will retreat due to a westward shift of the 500 mb high, effectively cutting off our favored southwesterly flow. That said, isolated thunderstorms forming off of westward outflows from Arizona monsoon activity cannot be ruled out in Mohave County each afternoon, though confidence on occurrence and location is too low to warrant a manual increase in PoPs. Temperatures will remain elevated through the week as a result, with "Moderate" HeatRisk for the lower elevations and "Low" HeatRisk for the southern Great Basin. Models continue to indicate a return of the monsoonal moisture next weekend, with decent member consensus in both the ECMWF ensemble and GEFS PWAT meteograms. Stay tuned! && .AVIATION...For Harry Reid...South-southwest winds will persist through the remainder of the night becoming light and variable after 15z. Thunderstorm chances increase after 19z today with outflow winds potentially from multiple directions becoming a concern. Also, there is a small chance of another round of thunderstorms this morning, similar to what we saw yesterday morning, however confidence of occurrence is low. What we will likely see is increased mid clouds generally above 12k feet near daybreak. For the rest of southern Nevada, northwest Arizona and southeast California...Generally expecting diurnal type winds across the TAF sites this morning although a thunderstorm complex over SE Arizona could bring gusty outflow winds into the Colorado River Valley overnight affecting KEED and KIFP. Along with the outflow winds, there is some small probability of thunderstorms developing at or near these sites overnight and potentially as far north of the Las Vegas Valley by around daybreak. Elsewhere, isolated to scattered storms are expected this afternoon, continuing through sunset. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && DISCUSSION...Varian AVIATION...Salmen For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
