Area Forecast Discussion
National Weather Service Reno NV
254 AM PDT Fri May 27 2022

.SYNOPSIS...

Gusty winds, cooler conditions, and areas of showers will prevail
this weekend as a trough moves into the Great Basin. Strongest
winds are expected on Saturday but outdoor recreation impacts and
hazardous boating conditions can be expected through most of the
holiday weekend. Temperatures will cool off considerably behind
the front with the coolest temperatures expected on Sunday and
Monday.

.DISCUSSION...

An active weather pattern will be in place over the Memorial Day
weekend which will mainly come in the form of wind and a cool down
as a cold front moves through the region. While precipitation is not
the main story over the weekend, a few showers and even isolated
thunderstorms will be possible.

Gusty winds will be present through the weekend with Saturday
looking to be the windiest day of the lot. Winds this afternoon will
be gusty out of the southwest with peak gust in the 30-40 MPH range.
Winds aloft will ramp up tonight into Saturday morning as the main
axis of the jet moves across the northern Sierra. This should push
ridge level gusts 75-85 mph Saturday while valley locations reach
closer to the 40-45 mph range. A few wind prone locations along
US 395/I-580 could see gusts of 50+ mph. Winds aloft will begin to
ease Saturday night while surface winds shift northerly Sunday
morning as the cold front pushes through the region. Be mindful of
hazardous boating conditions across all areas lakes this holiday
weekend. Cross wind hazards for high profile vehicles, aviation
turbulence, and areas of blowing dust downwind of desert sinks/dry
lake beds are all on the table this weekend due to the gusty
conditions.

A few scattered showers will be possible as the trough progresses
inland tonight into Saturday morning, mainly northward of Susanville-
Gerlach. Showers could spread southward across the Tahoe Basin by
Saturday afternoon with isolated thunderstorms possible mainly
across Lassen County into the Surprise Valley. Snow levels could dip
down between 7,000-7,500` Saturday night as the cold front
approaches which could result in a few spotty snow showers in the
higher elevations but not expecting much in the way in terms of
accumulation as most of the shower activity will be dissipating
into Sunday morning.

Temperatures will hover near the 80 degree mark this afternoon
across western Nevada (upper 60s Sierra), followed by 5-10 degrees
of cooling on Saturday. Sunday and Monday are shaping out to be the
coolest days behind the cold front with high temperatures expected
to be in the mid-60s across western Nevada and mid-50s for Sierra
valleys. Sierra valleys will dip below the freezing mark by Sunday
morning with sub-freezing lows expected at least through Tuesday
morning. Western Nevada valleys look to remain in the upper 30s to
low 40s for most locations with about a 20-30% chance of seeing
freezing temperatures for colder rural valleys. Temperatures will
moderate by mid-week as high pressure rebuilds across the region.

.AVIATION...

Low pressure off the Pacific Northwest will provide multiple days of
breezy to gusty conditions with wind shear and turbulence possible
through much of the upcoming holiday weekend.

Wind gusts today will generally be in the 25-35 kt range with
Sierra ridgetop winds increasing to 70-75 knots overnight into
Saturday. Stronger gusts around 30-40 knots will be possible
Saturday afternoon followed by a wind shift out of the north by
Sunday morning as a cold front moves through the region.

Winds may produce areas of blowing dust and reduced slantwise
visibility downwind of dry lake beds and desert sinks through the
weekend. Light showers and even some isolated thunderstorms will be
possible through Saturday but the best potential will largely
remain north of Susanville-Gerlach outside of some light shower
activity across the Tahoe Basin on Saturday. Fuentes
