Area Forecast Discussion
National Weather Service Elko NV
228 PM PST Sat Dec 16 2017

.SYNOPSIS...High pressure will build into the region tonight and
continue through Tuesday for dry weather. The next storm system
will impact the region on Wednesday bringing accumulating snow.


.SHORT TERM...Tonight through Tuesday. A few lingering snow
showers across eastern White Pine county this evening from
departing storm system, otherwise dry weather through the period
as upper ridge builds back into the region. High temps mostly in
the upper 20s and 30s on Sunday warming into the 40s northern NV
and the mid 40s to the lower 50s central NV by Tuesday. Mostly
sunny skies on Sunday then partly to mostly cloudy Monday and
Tuesday as ample mid and high level moisture moves over flattening
upper ridge as next storm system approaches.

.LONG TERM...Tuesday night through next Saturday.

Long term starts with Pacific system sliding down the west coast.
Fast moving cold front swings through the state on Wednesday.
Strong 850-700 Fgen forcing coupled with 70-90kt 500hPa jet core
will likely lead to moderate to possibly heavy band of snow across
northern NV Wednesday morning. As the front drops south during
the evening, the jet weakens and moisture feed into central NV
becoming less favorable, leading to lighter snow and lower
amounts. Expect northwest wrap-around flow for Wednesday night for
eastern NV before tapering off Thursday around mid-day. Very
preliminary snow forecast calls for about 1-3 inches for northern
NV with around an inch or less across the central. Northern Elko
county and Rubies could see 3-6 inches. Winds will pick up out of
the southwest beginning Tuesday night across NW NV and then rest
of the state on Wednesday before turning northwest behind the
frontal passage. 700hPa winds 40-50 knots could mix down and lead
to potential of advisory-level winds. Have bumped up winds and
gusts in response. Behind the front, expect breezy northwest winds
to continue with strong pressure gradient across the CWA with
potential for higher downslope winds a possibility as well. Travel
Wednesday could be quite hazardous with winds likely leading to
blowing and drifting snow. Following the passage of the system,
northwesterly to northerly flow will prevail through weekend. This
will keep the temperatures below and should keep the weather
mostly dry.


.AVIATION...A cold front continues to pass south and east of the
region with snow showers dissipating near KELY this afternoon
with MVFR conditions in heavier snow showers possible. Expect IFR
conditions elsewhere with clearing mid-level clouds. Winds will be
breezy at times through early evening out of the north to
northwest 10-16G20-25kt near KWMC, KEKO and KELY terminals.
Stronger winds at KTPH 18-23G28-33kts through evening before
decreasing overnight into tomorrow but still breezy at times.
