Area Forecast Discussion
National Weather Service Las Vegas NV
415 AM PDT Sun Apr 20 2025

.SYNOPSIS...Temperatures will continue to rise over the next few
days with highs reaching their peak on Tuesday. A system arriving
mid week will bring a decrease in temperatures and increase in wind
toward the end of the week.

&&

.SHORT TERM...through Tuesday.

Warming temperatures, dry conditions, and generally light winds are
expected through Tuesday as heights increase in response to a ridge
building in the eastern Pacific. High temperatures today will be
about 10 degrees warmer than Saturday with an additional 7-10
degrees of warming by Tuesday. A few high clouds will drift across
the area this afternoon into Monday as a weak shortwave passes
through the Great Basin. Other than some high clouds, this shortwave
will have little overall impact.

.LONG TERM...Wednesday through next Sunday.

Midweek, a series of shortwaves will move through our zonal flow
aloft, which will slow down the rapid early-week warm up across the
region. In addition to pausing the warm up, these shortwaves will
bring periods of cloudy skies to the region and will increase south-
southwesterly winds across the forecast area each afternoon through
the work week.

Extended forecast details remain murky regarding a low pressure
system pushing into the Pacific Northwest next weekend. Details such
as strength, timing, moisture content, and trajectory remain unclear
at this time, but will become more clear with subsequent forecast
packages. Potential impacts will include gusty winds, a drop in
temperatures, and a return of precipitation chances.

.AVIATION...For Harry Reid...For the 12Z Forecast Package...Light
and variable winds this morning should go easterly around noon, with
speeds below 10 knots about 80 to 90 percent of the time. Winds
should veer to southerly late this afternoon before becoming light
and variable again early Monday morning. No operationally
significant clouds or weather expected.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 12Z Forecast Package...Winds will come around
to a generally southwesterly direction today, with the strongest
gusts of 20 to 30 knots over the higher terrain northwest of
Interstate 15. Scattered cumulus developing over the Sierra Nevada
could produce isolated obscuration of the highest peaks, while VFR
conditions occur elsewhere. Expect wind gusts less than 20 knots and
VFR conditions areawide Monday.
&&

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