Area Forecast Discussion
National Weather Service Elko NV
212 PM PST Tue Feb 20 2018

.SYNOPSIS...Cold temperatures along with a few snow flurries
mainly along mountain ranges are expected Wednesday across the
state. Another winter storm system moves into the region Thursday
bringing more snow to the state. Active weather will persist into
the weekend and possibly next week.


.SHORT TERM...Tonight through Friday.

After a considerably dry water year so far, active weather within
a persistent northwest flow pattern will bring several troughs
over the region through next week. Latest models have a
developing trough/low digging south-southeast from OR Wednesday
reaching southern southern NV Thursday. Although not a strong
anomalous event, the track of the low could prolong precip along
cold front boundary across northern NV Thursday night if pivoting
of boundary occurs. Dynamic models are not handling this
possibility too well so confidence in location of enhanced precip
area is low. Right now the NAM is most aggressive in depicting a
substantial band of enhanced snow (snow levels down to all
valleys) from northern Nye county, White Pine county to east
southeast and far eastern Elko county. Considering this an outlier
as for now so limited NAM exposure in forecast. Nonetheless, 1-3
inches of snow in valleys over much of the area is expected with
ensemble means around this range as well. Snow will diminish after
Friday from north to south with continued cold temperatures.

With light winds, temperatures should be a few degrees colder
tonight than last night, especially across snow covered areas in
northern Lander/Eureka counties and Elko County north and west of
the Rubies. However, upper-level cloud cover will be moving in
keeping temperatures up just a bit.

.LONG TERM...Friday night through next Tuesday.

The bulk of the next system looks to arrive Saturday evening
through Sunday. The models continue to trend towards it being
more of a clipper type system rather than one that digs deeper
into Nevada. This will favor northern Nevada more, especially Elko
County. It looks at this time to have enough moisture for some
accumulating snows, which will probably be limited by its fast
movement through the area. It also looks to be accompanied by
some pretty strong winds ahead of and along the front Saturday and
Saturday evening.

Temperatures will remain below normal in the extended, though they
will not be as cold as they were during the week.

The next system will be quickly on its heels and looks like it
will dig deeper into the West Monday through Tuesday, with snow
showers being more widespread across the area.
