.DISCUSSION...

Westerly winds increased overnight with ridge areas reporting wind
gusts from 35 to 60 mph. The winds will gradually shift to the
north and northeast with some breezes (gusts up to 20 mph) mixing
to the lower elevations today. Ridge winds will start to decrease
as the wind direction shifts midday. Some ridges may experience N
to NE ridge wind gusts up to 40 mph overnight into Monday morning.
This weak front passage tonight into Monday is looking mostly
dry, but there may be a handful of very light shower showers for
northern and eastern Pershing County this morning.

Weak and transient high pressure on Monday will keep temperatures
chilly as stronger valley inversions return. Valley areas may only
see highs in the 40s to near 50. High pressure over the eastern
Pacific will continue to block the primary storm door through this
week. Only storm access we will have will be for storms dropping in
from the north. Storms along this terrestrial trajectory will be
cold, but also dry. A weak passing wave on Tuesday will bring around
10% chances for passing sprinkles or flurries across far northeast
CA/northwest NV.

For Tuesday night-Wednesday, the main low is projected to drop
southward across the Great Basin bringing colder temperatures,
increased winds and the potential for light snow. As stated before
with the inland storm track, moisture will be limited and the fast
nature of the storm passage will greatly limit precipitation
amounts. Blended guidance only shows a 10-20% chance for 1" snowfall
for most of the eastern Sierra/Tahoe basin, and higher elevations of
Douglas-Mineral counties, except for a small part of northern Mono
and southern Lyon counties where this probability edges up to near
30%. For western NV valleys, brief snow showers late Tuesday night
could leave a dusting of snow (10-20% chance) but that`s about all
in terms of precip associated with this storm passage.

Enhanced northeast-east winds behind the front on Wednesday, will
reinforce brisk and chilly conditions through Wednesday night. Below
average temperatures prevail with highs only in the 30s for Sierra
communities and 40s for lower elevations on Wednesday, and 40s
across most areas on Thursday as valley inversions return.

.AVIATION...

Fast-moving weak weather systems will bring periods of increased
mountain wave turbulence and isolated LLWS today through Monday and
again Tuesday through Wednesday.

Westerly FL100/ridge top winds are currently gusting between 30-40
kt. These FL100 winds will begin to shift to NE-E with gusts to 35
kt at times this evening through Monday AM between 03-18Z. Most
terminals can expect a shift to N-NE winds with gusts 15-20 kt this
afternoon, except stronger WNW gusts near 25 kt are anticipated at
KMMH.

Otherwise, VFR conditions prevail regionwide through Monday with
areas of mid-high level cloud cover especially through this morning,
with little to no precipitation chances.
