.KEY MESSAGES...

*  Impactful winds and cooler temperatures are expected this
   weekend as a trough moves across the region.

&&

.DISCUSSION...through Thursday.

Today's weather features high temperatures 5 to 10 degrees above
normal and modest winds aside from gusty westerly winds in western
San Bernardino County. The next system arrives as a shortwave
traverses the Great Basin on Saturday, followed by a stronger area
of low pressure dropping south and east on Sunday and Monday.
Saturday's winds will take a southwesterly direction across much of
the Mojave Desert as the base of the shortwave moves overhead, while
winds in the southern Great Basin and eastern Sierra will take a
northerly to northwesterly direction. Confidence remains high in
reaching Wind Advisory criteria on Saturday in western San
Bernardino County given an 80 to 90 percent probability of reaching
gusts of at least 40 mph in the afternoon and evening. No changes
appear necessary in the headline for that time period. However,
models are coming to a consensus that strong northwesterly winds
will develop across much of the rest of the area on Sunday afternoon
and evening as stronger low pressure moves south. The NBM shows a 60
percent probability or greater of reaching Wind Advisory criteria
for most locations, but ensembles are also showing strong
indications of reaching High Wind Warning criteria (gusts 58+ mph)
across southeastern California and southern Nevada. Between the
ensemble guidance and the sharp, fast moving nature of the front,
decided to issue a High Wind Watch for southeastern California and
southern Nevada for Sunday afternoon and overnight.

Besides winds, this system will bring noticeably cooler temperatures
as highs decrease 15 to 20 degrees between today and Monday. Highs
will be around 10 degrees below normal for mid-May, which means
highs in the upper 70s in Las Vegas. There is also a 20 to 50
percent chance for precipitation in northern Lincoln County on
Sunday evening as the low moves in, but given a lack of substantial
moisture, any totals should be light. Temperatures gradually
increase Tuesday onward as high pressure rebuilds over the region.

.AVIATION...For Harry Reid...For the 18Z Forecast Package...Light
winds under 8KT following typical wind directions are expected
through late morning before turning southerly and becoming breezy
with gusts to 20 knots after 20Z. Gustiness will decrease after
sunset, although winds will remain elevated through the night. VFR
conditions under mainly clear skies are expected through Saturday
morning before high clouds with bases AOA 20kft AGL spread into the
area Saturday afternoon. Temperatures may briefly touch 100 degrees
between 22Z and 00Z this afternoon. Looking ahead, breezy southwest
winds with gusts over 25 knots are expected Saturday afternoon,
followed by the potential for strong winds Sunday afternoon and
Sunday night. Current guidance indicates around a 40 percent chance
of gusts exceeding 40 knots at Harry Reid after 20Z Sunday.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 18Z Forecast Package...Moderate westerly winds
will continue at KDAG into mid-afternoon before increasing, with
gusts to 30 knots expected after 22Z. Elsewhere, south to southwest
winds will increase through the afternoon, with most areas
experiencing gusts in the 15 to 25 knot range. The exception will be
at KBIH, where north winds gusting to 20 knots are expected this
afternoon. Winds across the region will diminish around sunset
except at KDAG, where gusty winds will persist through the night.
Lighter winds will develop overnight and continue into Saturday
morning before increasing once again Saturday afternoon. Widespread
gusty northerly winds in excess of 40 knots are possible across the
northern two-thirds of the region Sunday afternoon and evening.
