.DISCUSSION...through next weekend.

Mostly sunny and warm conditions prevail across the region this
afternoon. We are expecting a few very light showers to develop
with the afternoon heating across the Sierra region as well as the
Arizona strip, though none of the shower activity is expected to
be of much impact. On Monday, a weak low pressure center will move
into Arizona with a few light showers again expected across
Northwest Arizona, mainly east and north of Kingman and across the
Arizona Strip. Elsewhere, dry and warm conditions will continue
for Memorial Day.

By Tuesday, a fairly deep low pressure system will drop into the
Great Basin from the PacNW. The approach of this low and the
tightening pressure gradient will lead to gusty conditions across
much of the region, especially the Western Mojave Desert and parts
of southern Nevada. In coordination with our neighboring California
offices, went ahead and issued a wind advisory for the Western
Mojave Desert near Barstow for Tue-Thu, and additional wind
headlines will likely be required for areas further east as
confidence in the timing details increases. In addition to the
gusty winds, temperatures will begin to decline Tuesday, and
especially Wednesday-Thursday as the low remains in close
proximity to the region and subdues heights. As the low weakens
late in the week, temperatures will moderate and return to above
normal by the weekend.

In addition to the gusty winds and cooler temps, a few showers are
expected across the Southern Great Basin and Sierra region
Wednesday and Thursday as the low sits nearly overhead.
Precipitation amounts are generally expected to be light, but a
few stronger cores could produce lightning and brief downpours
given the steep lapse rates and cool air aloft. The low will
weaken by the weekend with precipitation chances ending.

.AVIATION...For Harry Reid...For the 06Z Forecast Package...Winds
maintain a southwesterly direction into the night, becoming variable
in the early morning hours. Late tomorrow morning, winds favor an
easterly to southeasterly direction, increasing to over 10 knots and
becoming gusty out of the south in the afternoon. Winds stay gusty
in the evening but shift to the southwest. FEW to SCT mid and high
clouds filter through the area.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 06Z Forecast Package...Southerly to
southwesterly winds continue across much of the area into the night.
Expect another round of gusty southerly to southwesterly winds
tomorrow across the region, with peak gusts between 20 and 25 knots.
The exception is KDAG, where a push of westerly winds gusting to 30
knots  arrives in the evening. Storms form over northwestern Arizona
in the afternoon and should remain outside of the vicinity of all
terminals. A few storms may also form near KBIH in the afternoon,
but confidence in them entering the vicinity was too low to include
in the TAF.

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