.DISCUSSION...

High clouds linger over portions of southern Nevada and
northwestern Arizona this afternoon as a dampening shortwave
embedded in southwesterly flow aloft exits the region toward the
Four Corners. Skies will continue clearing tonight, with light
breezes and temperatures 5 to 10 degrees above normal expected
once again on Tuesday.

On Wednesday, a stronger shortwave will translate eastward from
the Pacific Northwest across the Great Basin, and while this
wave does favor a more northward track, increased winds will be
the primary impact. Ensembles remain in very good agreement
regarding the timing and trajectory of the trough, with winds
ramping up mid-morning Wednesday and persisting through late
evening before diminishing as the wave and its attendant jet move
eastward. Wind gusts of 40 to 55 mph are looking increasingly
likely along the eastern Sierra Foothills and northern Owens
Valley Wednesday afternoon and evening, where crosswinds across
Highway 395 will produce hazardous travel conditions, especially
for high profile vehicles. While probabilities for Advisory level
winds remain above 50% for the higher terrain of the western
Mojave Desert as well as a localized stretch of US-95 near Desert
Rock, overall, gusts there and elsewhere are expected to range
from around 20-40 mph. In addition to the winds, there also
remains a slight chance (15-25%) for precipitation over the
eastern Sierra in northwestern Inyo County, though QPF continues
diminishing with under 0.10" currently forecast, and only a light
dusting of snow expected along the Sierra Crest. Highs Wednesday
will be similar to Tuesday, though in the wake of the departing
shortwave, temperatures will be 3 to 6 degrees cooler on Thursday,
still above normal for early November.

Friday into the weekend, thicknesses increase due to a building
ridge between the departing trough and a deepening trough
extending from the Gulf of Alaska southward across the eastern
Pacific. This will allow for a subtle warming trend, with
temperatures again reaching 5 to 10 degrees above normal with
light winds and plenty of sunshine.
