.DISCUSSION...through Monday.

After another day of quiet weather today, a shortwave trough will
move through the PacNW and Great Basin on Wednesday. Not overly
strong and more of a glancing blow, chances for widespread,
impactful winds (40+ mph) are low (less than 25%). Instead, any
wind impacts are likely to be the result of localized downsloping
in places likely US-95 near Desert Rock/Mercury and US-395 in the
Owens Valley. The latter has the greatest potential (~50%), and
these probabilities may be understated a bit with the seemingly
favorable setup. Beyond the winds, it is worth noting that there
are 20-30% PoPs on Wednesday in the eastern Sierra. Amounts will
likely be light as chances for 0.25"+ are only ~20%, resulting in
~30% probabilities for 1"+ of snow above 9,000 feet. Precipitation
chances and winds quickly diminish by Thursday morning.

Other than Wednesday`s system, the weather across the region looks
rather quiet. Winds remain light, above-normal temperatures persist,
and precipitation chances stay below 10%. Coolest temperatures
expected Thursday, but even then highs are forecast to be between 70
and 85 degrees in most locations.

.AVIATION...For Harry Reid...For the 12Z Forecast Package...Light
winds of less than 8 knots, following typical diurnal directional
patterns, will persist through Wednesday morning. VFR conditions
will prevail, with SCT to FEW high clouds with bases AOA 25kft AGL

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 06Z Forecast Package...Winds at most TAF sites
across the region will remain under 10KT and follow typical diurnal
directional patterns through Tuesday.  The exception will be in the
Owens Valley, including KBIH, where southerly gusts to around 20
knots are possible after 18Z. VFR conditions will prevail, with high
clouds with bases AOA 20kft AGL gradually clearing in most areas by
late Tuesday morning, except along and just east of the Sierra,
where bands of high clouds are expected to persist through the
period.
