.SYNOPSIS...A storm system will spread light snow across mainly
northern Nevada tonight and Monday. A stronger storm system will
bring more snow Wednesday night and Thursday.


.SHORT TERM...Tonight through Wednesday. Weak short wave will bring
some light snow to mainly northern NV tonight and Monday. Generally
up to an inch in the valleys of northern NV with local amounts up to
2 inches. Mostly 1/2 inch or less across central NV. Upper ridge
builds in Monday night for dry weather through Wednesday. Breezy
to windy Wed, especially central and northwest NV, due to

.LONG TERM...Wednesday night through next Sunday.
Long term period begins with cold front progressing southeastward
across the region Wednesday night into Thursday morning, bringing
a band of snow with its passage. Lighter snow showers expected
post-frontal with the broad upper-level trough overhead. A
secondary trough slides across the northern tier Thursday night
into Friday, brining more snow showers. Snowfall totals should
generally be light with valley locations north of US 50 possibly
picking up around 1-3 inches. Mainly dry conditions expected for
the weekend with ridging building over the western US. A few light
snow showers possible along the northern border on Saturday with
a warm front lifting north. Expect cooler temps Thursday and
Friday with highs in the 30s to low 40s, rebounding over the
weekend up into the 40s to possibly low 50s. Breezy winds expected
Wednesday night into Thursday with the frontal passage, but
expected to remain below advisory criteria at this time. Winds
decrease each day thereafter with ridging building in.


.AVIATION...A weak system will slide southeast across the region
tonight/tomorrow morning and will bring light snow that will
reach the vicinity of KWMC around 04Z, KEKO around 07Z, and
possibly KELY around 13Z. Snow could be strong enough at times to
drop vis and ceilings down to MVFR and possibly briefly to IFR.
Mountain obscurations expected. Snow will dissipate around midday
tomorrow but ceilings could hover near MVFR before improving late
