What forecasters said that day

The local office's own words before this high wind 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 high wind warning went out at Oct 27, 8:30 PM MST, 4 hours 2 minutes earlier.

Area forecast discussion, Oct 27, 8:30 PM MST, 4 hours 2 minutes before
Area Forecast Discussion
National Weather Service Las Vegas NV
830 PM PDT Fri Oct 27 2023

.SYNOPSIS...A fall weather system will bring gusty and cool weather
to the region this weekend. A High Wind Watch is in effect for the
Colorado River Valley Sunday afternoon through Monday afternoon, as
gusty north winds approach 60 mph. Temperatures gradually increase
back toward seasonal normals next week.
&&

.UPDATE...A band of mainly mid and high level clouds have been
moving across southern Nevada and northwest Arizona this evening
associated with a weak impulse. For the most part nothing much more
than some virga, with the exception of far northeastern Mohave
County where a very brief shower can't be ruled out of the question
for the next couple of hours. Not expected any first freezes of the
season overnight but possible Sunday morning in northern Mohave
County and in southern Nye County on Monday morning.
&&

.PREVIOUS DISCUSSION...1258 PM PDT Fri Oct 27 2023
.DISCUSSION...Today through Wednesday.

The First Freeze Warning for the Owens Valley was allowed to expire
on time this morning after hitting 32 degrees before sunrise.
Colorado City's morning low came in at 34 degrees this morning,
which was a few degrees cooler than the forecast, but not quite cool
enough to end the growing season. Morning low temperatures will be
similar Saturday morning across the region, but will drop
substantially Sunday morning as a result of a cold frontal passage.
This cold front will drop temperatures across the southern Great
Basin into the low 20s to upper teens, allowing northern Mohave
County to experience their first freeze of the season. On that same
vein, Kingman Airport has a 20% chance of freezing temperatures
Monday morning, which we will continue to monitor through the
weekend.

In addition to a drop in temperatures, this cold front is going to
increase northerly wind gusts across the forecast area. Saturday
afternoon, north-northwest winds will increase across Inyo and
Esmeralda counties, extending south and eastward through the evening
across the Mojave Desert with gust speeds between 30 and 45 mph.
These north winds will funnel along the Colorado River Valley, and
could exceed 60 mph due to topographic enhancement. A High Wind
Watch is in effect for the Colorado River Valley from Saturday
evening through early Monday morning. These winds will allow wave
heights to range from 2 to 4 feet across Lake Mead, Lake Mohave, and
Lake Havasu, with wave heights in excess of 4 feet over deeper
waters. This wave activity will result in hazardous water
conditions, so recreation on area lakes is ill-advised.

In addition to gusty winds and cool temperatures, dry air will move
in behind the cold front. This will result in increased fire danger
across the region. For details, see the FIRE WEATHER section below.

Temperatures will gradually increase next week underneath an upper-
level ridge.
&&

.FIRE WEATHER...Elevated fire concerns expected Saturday through
Monday as a windy, dry weather system moves through the region.
