.SYNOPSIS...A strong storm system will bring snow and windy
conditions to the state Sunday. Blowing dust and Blowing snow is
possible especially across central and east-central Nevada Sunday
afternoon. The lowest temperatures this winter will occur Tuesday
and Wednesday morning with sub-zero readings expected. Active
weather and snow returns late next week.

&&

.SHORT TERM...Tonight through Tuesday.

A relatively strong storm system is expected to impact the state
Sunday. Wind and an appreciable amount of snow Sunday will be
followed by very cold temperatures Monday and Tuesday.

Snow impacts: A swath of 2 to 4 inch snow accumulations in valley
locations are expected from central Nevada northeastward into Elko
county. Mountain locations across the Jarbidge area, Ruby
mountains and GBNP will get close a foot of snow. Snow will move
south across the CWA beginning at the NV/ID border late tonight
reaching northern Nye county by Sunday afternoon. Snow showers
will linger into Sunday night with another weak reinforcing short
wave moving across northern NV Monday bringing another one half
to one inch of snow mainly southeast of the Ruby mountains.

Winds: West to northwest winds gusting up to 60 mph along
ridgetops is likely with 25-35 mph range in valleys across
central and east central NV. The strong pre-frontal winds is
expected kick up some dust across the dry lake beds in western NV
that will migrate into Lander/Eureka counties and northern Nye
county. In addition, blowing snow will be of a concern with
blizzard- like/white out conditions possible in favorable
locations. Winds will peak Sunday afternoon and subside Sunday
night. Winds could remain elevated across northern Nye county
through Sunday evening so it`s something to keep an eye on as far
as possible extension of the wind advisory.

Temperatures: Temperatures will drop Sunday and continue to drop
through Monday night as strong CAA occurs over the region.
Temperatures will be around 0 for a a large part of the state
Tuesday morning with many sub-zero readings expected in areas with
denser snow cover. High temperatures will be in the lower to mid
20s across the CWA Tuesday. Temperatures will likely be the
coldest of this winter season.

.LONG TERM...Tuesday night through Saturday. Wednesday looks to
be the coldest day with highs in the 20s to lower 30s. Nighttime
lows will be very cold with the fresh snowpack. Widespread
subzero temps are expected Wednesday morning. Some locations may
approach -10 to -15 degrees in the colder valleys and where a
heavier snowpack exists.

Long wave trough pattern is expected to remain in place through
the end of the week. A series of waves will slide down the
western US and into our region. Models are struggling with any
sort of agreement in timing and placement of these systems, but
has improved slightly this aftn. Leaned more towards the EC
solution with its deeper troughs digging further south and west,
which the GEFS mean also trended towards. Confidence remains above
average for a wetter and colder pattern. It seems like winter
decided to show up to the Great Basin.

&&

.AVIATION...VFR expected through this evening. A winter storm will
impact the region with widespread snow and the potential for
blowing/drifting snow. KWMC/KEKO will start Sunday morning and
persist through Sunday evening. MVFR is likely with IFR/LIFR
probable. KELY and KTPH will see snow begin late Sunday night
through Monday morning with similar conditions to KEKO/KWMC.
Expect runway accumulations of an inch or so for KWMC and 2-4
inches for KEKO. Lesser amounts of 1-3 for KELY and an inch or
less for KTPH.
