What forecasters said that day

The local office's own words before this flash flood warning went out, 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 this flash flood warning went out at Sep 2, 12:14 PM MST, 1 hour 31 minutes earlier.

Area forecast discussion, Sep 2, 12:14 PM MST, 1 hour 31 minutes before

Area Forecast Discussion
National Weather Service Las Vegas NV
1214 PM PDT Sat Sep 2 2023

.SYNOPSIS...Numerous storms expected this afternoon and evening
with heavy rain and flash flooding expected. Drier conditions will
spread across the region tomorrow with storms becoming more
limited to Northwest Arizona and eastern Nevada. Dry conditions
return area wide Monday onward with cooler than normal
temperatures for Labor Day trending above normal by next weekend.
&&

.SHORT TERM...through Sunday night.

Storms are starting to ignite across the region as peaks in the
cloud cover have allowed convective temperatures to be reached. As
expected, given our very moisture rich airmass sampled in this
mornings 12z VEF sounding, storm development thus far has been
very rainfall efficient. A storm near Sandy Valley, NV recently
produced nearly 1.5 inches of rain, much of which came down in
less than 30 minutes. As storm coverage increases through the
afternoon, additional pockets of very heavy rainfall are likely
with flash flooding a big concern. As mentioned in this mornings
update, the 12z HREF suggests storm development early this
afternoon could favor the Spring Mountains and western Clark
County, with activity creeping into the western Las Vegas Metro
by later in the afternoon.

Drier air will begin to work in from the west on Sunday thanks to
our offshore Pacific trough finally moving inland and into the
Great Basin. This will tend to limit the thunderstorm chances into
our eastern zones, especially across Lincoln County and northern
Mohave County, through a few scattered storms could pop as far
west as the Spring Mountains. Additionally, breezy southwesterly
winds will accompany the approaching trough, with a few gusts to
near 40 mph especially across the Western Mojave Desert and near
the Sierra.

.LONG TERM...Monday through Saturday.

The first half of the workweek will favor continued troughing across
the western US, with our region sandwiched between shortwave troughs
traversing the PacNW and Great Basin regions, while low amplitude
high pressure holds firm over northern Mexico. This will keep
temperatures a few degrees below normal for Labor Day with
occasional afternoon breezes. Temperatures will remain on the cool
side of average through Wednesday before high pressure begins to
build northward later in the week. This will spark a warming trend
Thursday through Saturday as high temperatures climb slightly above
normal. Good news for flood clean up efforts, dry conditions are
expected area wide through next weekend.

&&

.AVIATION...For Harry Reid...Light easterly winds until around 20z
when winds begin to turn southerly and convection is forecast to
develop. Similar to yesterday, storms are expected in the Las Vegas
Valley through the afternoon and evening hours. Heavy rain, reduced
visibility, CIGs below 6000 feet with terrain obscuration, and gusty
winds will all be possible. Convection should be out of the valley
by 06z, but abundant low-level moisture from heavy rain may keep
CIGs at or below 6000 feet through the night. Light and variable
winds overnight.

For the rest of southern Nevada, northwest Arizona and southeast
California...Similar to yesterday, storms are expected to develop
early this afternoon and continue into evening hours. Heavy rain,
reduced visibility, CIGs below 6000 feet with terrain obscuration,
and gusty winds will all be possible. Convection should largely be
done by 06z, but abundant low-level moisture from heavy rain may
keep CIGs at or below 6000 feet through the night in locations that
see the most rain. Light and variable winds overnight.

&&

.SPOTTER INFORMATION STATEMENT...Heavy rain and thunderstorms are
expected through this evening. Spotters are encouraged to report
heavy rainfall, flood impacts, and any other severe weather
according to standard operating procedures.

            Overturned big rig resulting in the closure
            of 3 lanes. Heavy rain and wind were
            reported with this report. Dispatch was
            unclear if it was a blow over or hydroplane
            situation. Later social media post showed
            powerlines blown down as well near the
            interstate, thus it seems reasonable to
            assume the big rig was blown over.
