Area Forecast Discussion...UPDATED
National Weather Service Elko NV
755 AM PST Thu Feb 22 2018

.SYNOPSIS...A winter storm system moves through the region today
bringing snow to the state. Active weather will persist through
the weekend and into next week.


.UPDATE...banded snow is falling over Humboldt County with 3+
inches at WMC in the last several hours and still snowing lightly.
Bands will continue east over the Interstate 80 corridor and so
have issued an impact based WSE for Humboldt, northern Elko,
southwest Elko, and northern Lander/Eureka through 4 pm PST.
Amounts will vary widely with 1-3 common and 2-5 possible on
passes, summits and ridges. Sadly, some of the bands are falling
in radar no-man`s-land or in blocked areas so using satellite to
estimate some locations of heavier showers.



SHORT TERM...Today through Saturday. A winter storm is moving
through the region today bringing snow showers to much of the
area. The amount of snow is decent given our lack luster winter so
far with valleys receiving one to two inches an possibly up to
three inches in favored spots. The mountains should receive a bit
more snow of 4 to 8 inches. Travel impacts should be fairly brief
with passes having the highest chance for impacts. The system
should depart the region by friday afternoon with a brief calm
period for NV. Another storm system will begin to move into the
region by Saturday bringing renewed snow showers. This system
should produce very similar impact to the region although will
lesser total accumulations. Temperatures will remain frigid with
most areas remaining below freezing.

LONG TERM...Saturday night through next Wednesday.

A cold and occasionally snowy pattern will continue across
northern and central Nevada through the extended forecast period.
A series of progressive shortwave troughs embedded within the
northwest to north flow aloft will rotate through the broad upper
trough over the western CONUS during this time.

Both the GFS and EC models are in good general agreement that a
couple systems will likely affect the region through Wednesday:
Saturday night, then Monday into Tuesday. Both of these systems
are progged to drop down from the north and move through fairly
quickly, so each will likely only result in another couple inches
of snow for the valleys.

AVIATION...VFR conditions are expected to hold through about 13z
Thursday at KWMC and KEKO...and through about 20Z at KELY. KTPH
could remain VFR through Friday morning.

A cold front will bring snow showers with MVFR, and possibly
brief IFR CIGs/VISs to KWMC and KEKO between 13-16Z. In the wake
of the front, some scattered light snow showers/VCSH could linger
mainly around the mountains of Elko County.

Snow showers associated with the cold front are expected to
impact KELY, and possibly KTPH, with MVFR to intermittent IFR
conditions beginning around 20z Thursday.

Surface winds will gust around 20 kts ahead of the front.


Winter Weather Advisory until 4 PM PST this afternoon for
Humboldt County-Northern Elko County-Northern Lander County and
Northern Eureka County-Southwestern Elko County.
