The episode as NWS REV wrote it up.
A cold front pushed ahead of an upper trough deepening off the Pacific Coast brought another round of strong winds area-wide, along with a chance for light showers and cooler temperatures to the region. Winds were the primary impact as thermal gradients tightened along the cold front with an accompanying increase in upper winds from a strong 100+ knot jet core that lifted north-northeast over the region. This setup increased confidence for moderate travel, recreation, and even fire weather impacts over the region.

Area Forecast Discussion
National Weather Service Reno NV
132 AM PDT Fri Jun 17 2022
.SYNOPSIS...
Below average temperatures with breezes, clouds and chances for
showers and thunderstorms return for the weekend. Skies clear, winds
relax and temperatures return to above average territory for next
week. The long-range pattern shows signs of remaining active, with
temperatures near to below normal.
&&
.SHORT TERM...Today through Sunday night...
* Today will be yet another breezy one, but with the front
sliding southeastward, the highest winds will move along with
the front. Winds will impact the Sierra from Tahoe south and
through Mono and Mineral counties with gusts reaching 30-35 mph
for the lower valleys of the Sierra Front, and approaching 60
mph for the ridges. The wind speeds will continue to decline
through the day as the front moves across the Great Basin.
Blowing dust may be a concern for area travelers today, and
gusts may impact US-395 and US-95 along and south of Highway 50.
Area lakes will be choppy and prove difficult for small craft.
There are Blowing Dust, Lake Wind and Wind Advisories for areas
affected by high wind impacts. Shower chances increase through
the day today, largely concentrated near the Oregon border.
As the front passes, this will allow temperatures to tumble into
Friday night. Some low-elevation areas may even see patchy morning
frost early Saturday morning. Areas receiving precipitation may
see some snow/pellets mix in for higher elevations.
* Saturday we awake to a cloudy sky, with ongoing showers for
Surprise Valley and Lassen County. Showers will work southward
throughout the day, introducing some moisture along the
northern Sierra. Showers will be scattered with some isolated
thunderstorms, as well as snow showers for high elevations.
Chances of precipitation amounts >0.10" are generally 15-30%
for northeastern California and northwestern Nevada, and along
the northern Sierra. Winds will be lighter, but gusts 10-20 mph
are possible with 30-45 mph along Sierra ridges. Temperatures
will be well below average with lower valleys struggling to
reach upper 60s to 70. Sierra valleys will have to be satisfied
with upper 50s to 60. These temperatures set us up for another
chilly overnight, with patchy area frost possible again.
* Sunday will live up to its name, bringing sunny skies back to
the forecast. After a chilly start to the day, the exiting low
pressure system takes the cloud cover with it and allows the sun
to try to get to work on warming our area back toward average.
Northerly breezes will work to balance solar warming, keeping
temperatures just below average. -HRICH
.LONG TERM...Monday Onward...
High pressure is a touch slow to return as another weak shortwave
swings through the Sierra and western Nevada. Not much impact
expected here with some passing mid to high clouds, a slight wind
shift, and holding the below normal temperatures steady. High
pressure returns Tuesday to kick off the warming and drying trend
that will persist for the rest of the work week. Temperatures will
reach back into normal territory for mid-June with low to mid 90s
for western Nevada areas and 80s for the Sierra. More typical
westerly afternoon winds will return by Wednesday and Thursday with
gusts 25-30 mph possible.
Beyond Thursday, the ensemble clusters for the 8-10 day are showing
another trough dropping into the Pacific Northwest, and possibly
into the Sierra and western Nevada. With the lack of a strong ridge
signal, it keeps the door open for chances of precipitation and
cooler temperatures.

.AVIATION...
Strongest wind potential shifts southward as the cold front heads
towards southern Nevada. Wind gusts will be around 25-35 kts for
terminals along and north of Highway 50 (KRNO, KCXP, KRTS, KTRK,
KTVL). Stronger wind gusts will develop for areas just south of
Highway 50 with widespread 35-40 kts this afternoon and evening
(KMMH, KHTH, KMEV).
FL100 winds will remain elevated (30-50 kts) as the low pressure
system migrates slowly southeastward across the Sierra and western
Nevada. The risk for turbulence and LLWS will remain possibly into
Saturday afternoon even as the surface winds begin to subside later
tonight into Saturday.
Showers will be possible starting late tonight through Sunday for
areas along the Sierra into northern Lassen county. Saturday
afternoon will hold the biggest precipitation potential with chances
for showers from Alpine county northward to the Oregon border.
Thunderstorm potential (15-30%) will be highest for northern Lassen
county on Saturday afternoon, and while the chances for
thunderstorms will be lower for western NV, we can't rule out the
potential for a storm or two.

.FIRE WEATHER...
* Cold front pushed through overnight with cooler temperatures
spreading across much of the region, especially for areas north of
Highway 50. Conditions still remain very dry, even post-frontal,
with relative humidity values still projected to be in the teens
for much of western Nevada.
* The strongest wind gusts will shift southward today for areas
along and south of Highway 50. Wind gusts 45 to 50 mph will be
possible for these areas, including Mono-Mineral counties. Wind
prone locations may see gusts 60+ MPH at times. Fire weather
concerns will stay elevated for any localized areas of critically
dry fuels. Gusty winds still have potential to produce rapid fire
spread.
* There will be potential for some showers and possibly a
thunderstorm or two from late tonight into early Sunday for areas
along the Sierra and northward into Lassen and Washoe counties. 5-
10% chance for wetting rains (>.10") along the Sierra. Best
potential for thunderstorms to develop will be Saturday
afternoon/evening across Lassen county with a 25-30% chance.
