High Wind in Nevada, January 9, 2017

Area Forecast Discussion
National Weather Service Elko NV
258 PM PST Mon Jan 9 2017

.SYNOPSIS...A mix of rain and snow tonight, and again on Tuesday
mainly across northern Nevada, then a little cooler Tuesday night
into Wednesday with more widespread snow across northern and
central Nevada. Winds will be gusty at times through Wednesday.
Lingering snow flurries across northern Nevada Thursday, with snow
showers over central Nevada. Cooler and drier across the region
Friday into the weekend.

&&

.SHORT TERM...Tonight through Thursday. The air mass over east-
central Nevada this afternoon is a little unstable, which has
already produced a couple lightning strikes. May still see a few
more lightning strikes over or east of the Ruby mountains in Elko
County, or in White Pine County during the late afternoon hours.

Rain and snow continues this evening and overnight across mainly
northern Nevada. As cool trough energy currently off the Pacific
NW coast gradually slides down the west coast and inland toward
Nevada, precipitation will expand into Central Nevada with snow
levels lowering slightly. Have issued a winter weather advisory
for elevations above 5000 feet in Humboldt and Northern Lander and
Eureka Counties from 10PM this evening through 10PM Wednesday
evening. Have also issued a winter weather advisory for all
elevations across all of Elko County except zone 33, which is
Southeastern Elko County. Main concerns are current wet and
slushy surfaces that will refreeze during the night times, as well
as receive a total of 2-6 inches of new snow over the next couple
day and lead to periods of icy and snowy roadways. Mountains
across northern Nevada will see higher snow amounts by Wednesday
evening, generally 6 to 18 inches.

With the upper level jet stream over or close to the region, winds
will also be gusty at times over the next couple days. Weak
instability sets up over portions of northern and central Nevada
the next couple days, however at this time there is not enough
confidence to add lightning to the forecast. Greatest instability
will be Tuesday afternoon through Wednesday afternoon.

Precipitation tapers off across most of northern Nevada Wednesday
night, however snow should increase over Central Nevada Wednesday
night through Thursday afternoon. This may end up being advisory
level snow amounts, and will be monitoring the next couple model
runs to see if an advisory will need to be issued.

On Thursday as snow tapers off across northern Nevada and drifts
down over central Nevada, cooler air will move in across the cwa.
At this time expecting highs on Thursday to remain below freezing
across most of northern and central Nevada.

.LONG TERM...Thursday night through Monday. Thursday night
through friday morning. The trough that will be over the Great
Basin should continue to move southeastward out of the area while
a weak ridge begins to build over the Great Basin. Moisture from
the trough will still be present in central Nevada Thursday night
which should produce some light snow showers. These snow showers
will gradually tapper off through the night and Friday morning as
the moisture is drawn southeastward by the trough. This should
leave only remnant snow showers on a few mountain ranges by Friday
afternoon.

Friday through Monday. A ridge will continue to build across the
Great Basin on Friday which should produce a dry calm period for
the silver state. There will be some intrusion of clouds during
the week associated with some storm system that will pass to the
north of the state with no expected weather. The only exception to
this might be on Monday when a little moisture could produce some
snow showers on the northern most mountain ranges in Nevada.

&&

.AVIATION...Rain and snow showers will continue to affect
primarily northern Nevada through Wednesday before shifting south.
Rain showers should transition back to snow this afternoon. Low
ceilings in the MVFR range will be present at all terminals
through Tuesday afternoon. These low ceilings can cause mountain
obscuration conditions. Strong Gusty winds will be present at
KEKO, KELY, and KWMC during the afternoon hours.

&&

.HYDROLOGY...Snow levels will be lowering to most valley floors
into this evening, with a little more snow tonight, then rain and
or snow again on Tuesday. While no flooding is expected along the
Humboldt River, some of the smaller creeks and streams may reach
bankfull since they respond quicker to rain on snow conditions.
Small creeks and streams in the Paradise Valley area of Humboldt
County, such as Martin Creek, are rising since rain has been
concentrated over Humboldt County this past weekend. Northern
Lander, northern Eureka and Elko Counties may also see some rising
waters in smaller streams and creeks into this evening as
snowmelt continues.

Wednesday for Humboldt County-Northern Elko County-Northern
Lander County and Northern Eureka County-Ruby Mountains/East
