.PREV DISCUSSION... /ISSUED AT 259 PM /

SYNOPSIS...A storm system is quickly exiting the region this
afternoon. After a chilly start to your Saturday morning,
temperatures will rise into the 40s and 50s. There will likely be
some rain and or snow showers along the Idaho and Nevada border
during the morning and afternoon. Heading into your Sunday and
beyond, temperatures will rise to well above average levels. Don`t
put away those shorts and T shirts just yet.

SHORT TERM...This afternoon through Monday.

Rest of today and tonight - Satellite shows lingering snow showers
across northern NV. Little to no additional accumulation is
expected. Winds continue to weaken, but will keep adv/warning in
place for now. This may be cancelled later this aftn or early
evening.

Any wet roads across the area could experience some patchy black
ice. The highest risk would be across northern Elko County.

Backed off on for for tonight as pressure gradient winds have
dried the region out. Also, little to no precip feel south of I80.
Therefore, trimmed back the fog potential to only northern Elko
and eastern Humboldt Counties.

Saturday - With the cold airmass in place, rising heights and WAA will
increase the chances for light amounts of snow/rain along the
NV/ID border. At this time, no impacts are expected, but light
accumulations of snow and/or rain are possible. A couple inches of
snow is possible in the mountains. Any morning fog would quickly
dissipate, especially where winds are forecast to increase early
morning as a warm frontish will push north.

Sunday - Heights will continue to rise and temps will climb into
the 60s and approach 70 for some lower valleys.

Monday - The fall ridge really flexes its muscles into Monday
with heights at H5 near 594dam. This will likely produce 70s
across most of the area, which is well above average. Due to dry
air and clear skies, mornings will still be chilly. Most lows will
be in the upper 20s to 30s.

LONG TERM...Monday night through next Friday.

Strong ridge dominates the west coast in all the models with the
Great Basin under the downstream side. Models depict a 596 dm high
if they pan out. This could easily bring near record highs to many
places Wednesday. Thursday, the ridge breaks down a but under the
onslaught of a strong wave dropping down the east side. This wave
will be mostly dry so pops kept low enough to prevent showers in
the forecast, at this doing. Main effect will be to cool temps
down Thursday and Friday. Tuesday highs: 60s/70s, lows 30s/40s.
Wednesday: 60s/upper 70s, lows 30s/40s. Thursday, Friday: upper
50s/low 70s, lows 20s/30s.

A bit breezy on Thursday.

AVIATION...Clouds pulling out slowly as the cold air invades the
Great Basin. Expecting VFR at all sites overnight and through 00Z
Sunday. But...expect VCFG at KWMC and KEKO and enroute over
northern Nevada. Lower clouds will obscure mountain tops all sites
at times but will improve Saturday. West to northwest winds
gusting to 20-40 mph will decrease overnight and local terrain
winds will dominate by sunrise. Lighter southwest to northwest
winds Saturday.
