The local office's own words before this wind advisory 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 wind advisory went out at Apr 23, 9:56 PM PDT, 1 hour 43 minutes earlier. Its key messages:

  • * Another weather system arrives over the weekend, bringing precipitation, increased winds, and cooler temperatures.
Area forecast discussion, Apr 23, 9:56 PM PDT, 1 hour 43 minutes before
Area Forecast Discussion
National Weather Service Las Vegas NV
956 PM PDT Thu Apr 23 2026

.KEY MESSAGES...

* Another weather system arrives over the weekend, bringing
  precipitation, increased winds, and cooler temperatures.

&&

.DISCUSSION...through Wednesday.

Light winds, dry conditions, and near normal temperatures will
continue through tomorrow. A low pressure system will bring cooler
temperatures and unsettled weather to the region over the weekend.
As this system pushes into the area on Saturday a 40 knot jet at 850
mb will develop over the western Mojave Desert, resulting in gusty
westerly winds in the Barstow-Daggett area with breezy southwesterly
winds across the rest of the Mojave Desert. These gusty westerly
winds will continue through Sunday for the western Mojave Desert.
Precipitation chances will begin to increase Saturday afternoon,
continuing into Sunday as the low moves through. The best
precipitation chances will be in Inyo County and the southern Great
Basin where there is a 50 to 75% chance of rain this weekend.
Precipitation chances will decrease as you head south with
precipitation expected to favor areas of higher terrain. Most of
this precipitation will fall as rain, but elevations above 7,000
to 8,000 feet may see flurries to a dusting of snow. Weather looks
to remain unsettled as we head into next week as another low
pressure system approaches the area. However, confidence in
details and impacts are low at this time.

&&

.AVIATION...For Harry Reid...For the 06Z Forecast Package...Winds
remain light tonight and Friday morning. By late morning or early
afternoon, breezy southwest winds are expected to develop with gusts
of 15-25 knots. Onset likely between 19z-21z. Gusts subside around
sunset, but winds remain around 10 knots overnight. Few to scattered
clouds at or above 12kft.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 06Z Forecast Package...Light winds tonight and
Friday morning across the region. By late morning or early
afternoon, southerly to westerly winds increase with gusts generally
15-25 knots. Gusts subside around sunset in most locations, but
persist across the western Mojave Desert into the night. VFR
conditions prevail with just mid-level and high clouds passing
through.

&&

.SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report
any significant weather or impacts according to standard operating
procedures.
