A second in the series of winter-like, spring storms swung into the Sierra later April 13 and early morning April 14 with sufficient forcing and moisture to spread higher elevation snow showers mostly north of Lake Tahoe. Gusty westerly winds brought some wind impacts to western Nevada and the eastern Sierra.

Area Forecast Discussion
National Weather Service Reno NV
310 AM PDT Thu Apr 14 2022
.SYNOPSIS...
Where was this weather pattern back in January? There will be
multiple storm systems moving through the region over the next 1-2
weeks. Several periods of mountain snow and travel disruptions
along with strong winds are likely. Temperatures will be warmer
than they have been, but will generally be near to below normal.
&&
.SHORT TERM...
No big changes to the current system rolling into the northern
Sierra today. Scattered snow showers along the Sierra north of
Sonora Pass this morning will become more widespread by later
this morning/afternoon as the trough moves inland and the front
and upper jet are best aligned. The cold front is not expected to
sag much farther south than I-80 by late today, so the best chance
of some spillover precipitation will be across northeast CA into
far northwest NV with strong shadowing persisting farther south.
QPF remained mostly unchanged from the previous forecast with 1-2"
along the northern Sierra (west of Hwy 89), 0.25-0.50" across
northeast CA and far northwest NV, and generally less than 0.10"
elsewhere. This will equate to 2-6" of snow for the Tahoe Basin
and portions of northeast CA/northwest NV and 12-18" along the
northern Sierra crest. Given the bulk of the snow is moving into
the region during the day, the worst conditions will be along and
west of Hwy 89 and over the northern Sierra passes with wet roads
more likely farther east in the basin and across lower elevations.
Winds are going to continue to be gusty today with choppy lake
waters, rough air for planes and travel difficulties for high
profile vehicles.
Snow tapers tonight with mostly dry and milder conditions for
Friday. Winds too will be a bit weaker but still breezy in the
afternoon. The next system will arrive Friday night with winds
cranking up over the ridges once again and eventually surfacing
overnight as gradients tighten. Snow will arrive in the northern
Sierra late Friday evening and spread southward along the crest
overnight. Expect deteriorating conditions for area passes,
especially after midnight when the heavier precipitation rates
arrive. Snowfall in the Tahoe Basin itself is a bit more uncertain
as snow levels are expected to rise a bit ahead of this storm.
Spillover will be limited until later into Saturday when the cold
front approaches. Hohmann
.LONG TERM...
...Saturday Onward...
The next round of precipitation and gusty winds will push into the
Sierra and western Nevada late Friday into Saturday. If you have
travel plans, incorporate travel disruptions due to rain/snow/winds
into your travel plans Friday night into Saturday morning.
While the rain/snow is a welcome sight, the winds will be the
primary concern with this system. The wind potential is still around
50-70% chance for potentially damaging wind gusts (60+ mph) along
the Eastern Sierra, including the US-395/I-580 corridor from Reno
south into Mono County. With projected 700mb-600mb winds between 50-
60kts just ahead of the cold front passage, wind impacts will range
from high-profile vehicle restrictions to choppy lake conditions
and rough air for aviators. There is potential for spillover to
help dampen the winds a touch, but early Saturday morning through
at least midday will be quite blustery until the cold front pushes
through the region.
The primarily over-water trajectory of this storm will allow for a
better moisture tap, but it will also produce higher snow levels
than previous colder systems. The best potential for rain/snow will
remain in the Sierra, northeastern CA and portions of far
northern NV. Midday Saturday the cold front associated with the
storm will quickly pass through and allow for a brief period of
spillover into western NV, but overall the rain potential will be
low. Blended guidance shows a 30% chance of 0.25" of rain for
areas right along the Highway 395 corridor, but for the Basin and
Range a few drops may be the best this storm can drum up. With the
warmer nature of the storm and higher snow levels (~6000 feet),
plan on heavy/wet snow in the higher elevations, with primarily
rain or a rain/snow mix into the Tahoe Basin. For the Eastern
Sierra and Mono County, the moisture plume lingers long enough to
allow for some higher snow potential for the Sierra crest with a
60% chance of 6 or more inches through Saturday afternoon.
...Easter Sunday and Beyond...
The trend for a warmer and drier Easter Sunday has remained
consistent, with valleys in the low to mid 60s and possibly near 70
degrees. Ensemble cluster analysis and IVT probabilities show
signals for more storms next week with one on Monday and another
late next week as well. This means temperature swings will continue
along with periods of rain/snow and gusty winds too.

.AVIATION...
The active weather pattern continues with several periods of strong
winds, wind shear, and mountain wave activity; along with rain and
mountain snow. Be on the lookout for multiple periods where the
mountains may be obscured.
The first storm moving through this morning is bringing another
round of winds, snow, and rain to the region. Snow potential will
remain at Sierra terminals, including KTRK and KTVL where several
inches of accumulation will be possible. Areas of heavy snow is
expected along the Sierra crest. Wind gusts will be around 25-35 kts
today for most terminals.
The next stronger storm will move in Friday night into Saturday with
the strongest winds from the pre-dawn into mid-morning hours
Saturday. Gusts may exceed 40 kts for terminal sites with FL100
winds sustained at 50-55 kts. There will be more rain/snow mix to
the Sierra terminals with this storm. For the western Nevada
terminals, the winds will be the primary issues, but light rain may
be possible midday Saturday.
After a brief break Sunday into Monday, another storms moves in
Monday night into Tuesday. -Edan
