.DISCUSSION...

Although the Sierra ridges are 5-10 degrees cooler compared to
yesterday, the inversion that persisted yesterday in valley floors
around Reno and west central NV will be weaker, resulting in a
better chance of topping 60 degrees this afternoon.

This warmup will be short lived as today`s flat ridge retreats to
the CA coast tonight and Saturday, leading to a return of valley
inversions with highs dipping to the lower-mid 50s across western
NV. Then a weak slider-type low drops into the Great Basin on
Sunday, leading to an increase in north and northeast breezes
(gusts up to 20 mph), stronger Sierra ridge top winds (gusts 40-60
mph) and further cooling to around 50 degrees. Through the past
week we have been seeing varied storm tracks, but the most recent
consensus keeps the majority of the region dry, except for about a
10-20% chance of stray snow showers/flurries with no meaningful
accumulations near the OR border and scraping across
northern/eastern Pershing County Sunday morning.

For next week, the blocking ridge remains off the west coast,
keeping CA/NV in a cooler trough pattern with generally light
winds and valley inversions. One exception is a brief warm-up on
Tuesday ahead of a weak slider-type low dropping in from the
north, with increasing west winds for Sierra ridges.

This low is then projected to push a cold front through Tuesday
night-Wednesday with increasing north and northeast breezes for
lower elevations and stronger ridge top gusts (30-50% chance of
50+ mph). The magnitude of these winds will again be dependent on
the eventual track of this low, as the medium range ensembles
range from a drier brush-by scenario similar to this weekend`s
system, to a more southerly track that would bring increased snow
shower chances to the eastern Sierra and parts of western NV.
Given the limited available moisture with the inland trajectory
of this low, precipitation/snow amounts would remain on the
lighter side, with only a 10-20% chance of snowfall exceeding 1"
in the eastern Sierra/Tahoe basin and less than 10% chance for any
accumulating snow in lower elevations early Wednesday. MJD

.AVIATION...

Widespread VFR conditions and light breezes prevail through much
of Saturday with high pressure overhead retreating to the west
coast. Areas of cirrus cloud cover will limit the potential for
patchy FZFG at KTRK to less than 20% for the next couple of
mornings.

FL100/ridge top winds increase from the west with gusts 35-50 kt
Saturday afternoon-night, leading to periods of mountain wave
turbulence for the main terminals, then shift to northeast with
similar speeds on Sunday. MJD
