.DISCUSSION...Today through Sunday.

Temperatures will drop 8 to 12 degrees this afternoon compared to
yesterday as a closed area of low pressure approaches the region.
Breezy southwest winds will continue across the forecast area this
afternoon with gusts between 20 and 30 mph. The exception will be in
western San Bernardino County where gusty west winds will peak
between 40 and 45 mph. For this zone, the Wind Advisory will
continue until 11 PM tonight. A shortwave embedded in the upper-
level trough will push through the southwestern Great Basin this
afternoon as it taps into 0.40-0.50 inches of PWAT. As a result,
expect scattered showers and isolated thunderstorms across northern
Inyo, Esmeralda, and central Nye counties this afternoon. Showers
will generally produce between 0.10 and 0.25 inches of rain. With
thunderstorm activity, expect locally heavier rainfall as well as
gusty winds from their direction. The center of the low will move
overhead on Tuesday, which will return shower and thunderstorm
activity to the southern Great Basin for one final day before dry
conditions return for the remainder of the work week.

Mid-to-late week, ridging returns over the region, resulting in
temperatures climbing to over 10 degrees above-normal. Heat Risk
increases to Moderate (Level 2 on a scale 0 to 4) for desert valleys
Friday through Sunday, as it gradually spreads across the Mojave
Desert heading into the next work week. Las Vegas has a 15 percent
chance of observing the first 100 of the year on Saturday and a 40
percent chance on Sunday.

.AVIATION...For Harry Reid...For the 06Z Forecast Package...Gusty
winds remain the primary concern through the forecast period.
Elevated southwesterly winds with sustained speeds around 10-12KT
are expected early in the period with sporadic higher gusts to
around 20KT possible. There is still moderate confidence in a
brief lull and a shift to a more southerly direction late tonight
through mid-morning, before gusty southwesterly winds resume.
Sustained speeds between 15-20KT and gusts to 25-28KT will
continue thereafter through at least late evening, with winds
expected to diminish overnight. During the late afternoon,
intermittent higher gusts closer to 30KT may occur, however,
expectation is for gusts to remain below that threshold. VFR
conditions will prevail with SCT-BKN clouds passing over the area
with bases at or above 10kft.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 06Z Forecast Package...Gusty southwesterly
winds are gradually diminishing across the area, though sustained
speeds overnight will remain around 10-12KT, and sporadic higher
gusts to around 15-18KT possible. Mid morning, gusty southerly to
southwesterly winds resume, with speeds generally around 15-18KT
with gusts to 20-30KT common thereafter through the end of the
period. Exceptions to this include the western Mojave Desert where
gusty west-southwesterly winds will continue for the duration,
with gusts to 35-40KT expected, as well as KBIH in the northern
Owens Valley, where light northwesterly winds will continue
through late morning before gusty up-valley winds resume late
morning. Showers and thunderstorms are also expected on Monday
afternoon and evening, particularly across the Sierra and Owens
Valley and across the southwestern Great Basin. These storms will
be capable of producing erratic gusty winds, lightning strikes,
and localized reductions in ceilings and/or visibility. Otherwise,
VFR conditions will prevail, with SCT-BKN ceilings at or above
12kft, and as low as 8kft in the vicinity of convection.
