Area Forecast Discussion
National Weather Service Las Vegas NV
954 AM PDT Wed May 1 2024

.SYNOPSIS...Near to slightly above normal temperatures are
expected through Friday with periods of breezy conditions
expected. By the weekend, a quick moving weather system will bring
an increase in gusty winds to the region along with a shot of
cooler temperatures for Sunday and Monday. Temperatures will
rebound closer to normal by next Tuesday.
&&


.UPDATE...Above-average temperatures, mostly clear skies, and gusty
north-northwest winds expected across the forecast area today. Not
expecting widespread gusts to 40 mph, but can`t rule out these
speeds in the higher elevations of the southwestern Great Basin...
specifically across northern Inyo, Esmeralda, and southern Nye
counties this afternoon. Otherwise, expect gusts between 25 and 35
mph. These gusty winds will then concentrate along the Colorado
River Valley Friday afternoon. No changes made to the forecast this
morning, as it looks to be in good shape.

.PREVIOUS DISCUSSION...115 AM PDT Wed May 1 2024/


.SHORT TERM...through Friday.

Shortwave trough migrating through the Intermountain West will
drag a weak cold front through the area today, with breezy northwest
winds expected and temperatures a few degrees cooler than the highs
observed Tuesday. Strongest winds today look to occur largely in
conjunction with the frontal passage, peaking in the morning hours
and gradually easing in the afternoon and evening, exception will be
in our southern Great Basin zones where fairly steady northwest
winds will hang around through much of the day. Winds will ease
across most of the region on Thursday, but will hang around through
mid-afternoon in the Colorado River Valley. Flow aloft will return
to a more zonal direction by Friday, with temperatures climbing a
few degrees above average and along with a return of fairly typical
springtime afternoon westerly breezes.


.LONG TERM...Saturday through Tuesday.

Forecast confidence is higher regarding a low pressure system
forecast to bring some type of impact to our region this weekend.
Saturday afternoon, the EC ENS has a closed low centered along the
Oregon coast while the GEFS has it centered near the northern
California coast. This general positioning of the low results in
warm, above-normal temperatures and widespread windy conditions
across the area. At this point, the highest potential for wind
headlines would be across the southern Great Basin. Depending on the
depth and track of the low, precipitation chances increase across
the Sierra and east across south central Nevada Saturday night and
Sunday while our southern desert areas remain dry.

Cooler air sweeps in across the region for Sunday with temperatures
forecast to be about 15 degrees cooler than Saturday or close to 10
degrees below normal. The system is then east of the area Monday
with temperatures rebounding nicely. Given the time of year, highs
are forecast to be back to normal by Tuesday.

.AVIATION...For Harry Reid... Occasional gusty southwest winds
overnight will become light and variable toward sunrise. Expect to
see northwest winds increase after 15z as a disturbance moves into
the Great Basin. Northwest winds 10-20 knots are then expected
through the remainder of the afternoon and into the evening. Skies
will remain clear.

For the rest of southern Nevada, northwest Arizona and southeast
California...Northwest winds will increase across the region this
morning and afternoon as a weak system moves into the Great Basin.
Wind speeds will generally be 10-20 knots and will persist into this
evening before diminishing. Skies will remain clear.
&&


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