National Weather Service Las Vegas NV
700 PM PDT Wed May 18 2022

.SYNOPSIS...Temperatures will remain well above average today and
tomorrow. An incoming system will bring gusty west/southwesterly
winds and fire weather concerns on Thursday. Winds will gradually
calm down throughout the day on Friday with temperatures cooling
and returning to normal. These seasonal temperatures won't last
long, as ridging is expected to build in over the region early
next week which will allow for the return of above average
temperatures.

&&

.UPDATE...Some passing cirrus may make for a colorful sunset this
evening, but otherwise not much to talk about weather-wise. Light
winds continue this evening but breezier weather will return
tomorrow.  No updates needed tonight.

&&

.SHORT TERM...through Thursday evening.

Ridging and dry northwesterly flow will allow above average
temperatures to persist through tomorrow. Thursday will be the
warmest day of the week for much of the region. Locally, the 13Z
NBM4.0 boasts a 60% chance for the Las Vega area to see their
first official 100 degree day of the year. In addition to tomorrow
being the warmest day of the week, it will also be the windiest
day of the week. West/southwesterly winds will pick up across the
area on Thursday afternoon as an upper-level trough moves through
the Great Basin region. The strongest of these winds are expected
in western San Bernardino County, the eastern slopes of the
Sierra, and the southern portion of the Owens Valley. 40-50+ mph
wind gusts will be possible in the aforementioned areas tomorrow
afternoon and evening. As such, a Wind Advisory has been issued
for these areas beginning at 2 pm PDT on Thursday afternoon. These
gusty winds will continue into the overnight hours before
gradually dropping off early Friday morning.

.LONG TERM...Friday through next Wednesday.

Residual gusty winds from Thursday will linger through Friday
morning for parts of the forecast area. These wind gusts will
gradually drop off throughout the day as winds shift to a more
northerly direction. Temperatures will cool down behind the front,
with seasonal temperatures expected on Friday and Saturday. Forecast
confidence decreases as we move beyond Saturday due to uncertainty
regarding how quickly the trough will move out and the amplitude of
the ridging that builds into the region behind the trough. This will
mainly impact how quickly we warm back up to above average
temperatures. If the trough quickly clears out of the region with a
higher amplitude ridge building in behind it, temperatures will warm
up quicker. Should the opposite occur, the warmup will be more
gradual.

&&

.FIRE WEATHER...High temperatures will continue to run 8-12 degrees
above normal through Thursday. Stronger southwest to west winds will
develop Thursday afternoon and evening. Combination of those winds,
single digit humidity values and dry fuels would create critical
fire behavior. A Red Flag Warning has been issued for all of
southern Nevada and northwest Arizona. Stronger winds linger within
the lower Colorado River Valley into Friday with the Red Flag
Warning continued. Elsewhere, the Fire Weather Watch has been
cancelled as winds don't look as strong Friday.

&&

.AVIATION...For Harry Reid...Light easterly components late this
afternoon through early evening will give way to light southwest
components overnight. Gusty southwest winds around 25 knots will
then develop late Thursday morning through Thursday evening.
No operationally significant clouds.

For the rest of southern Nevada, northwest Arizona and southeast
California...Light winds will continue tonight across the region
then gusty south-southwest winds 25-30 knots will develop late
Thursday morning through Thursday night for most TAF sites. The
strongest winds will be over the western Mojave Desert with gusts of
35-40 knots expected at KDAG. No significant clouds.

&&

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