Area Forecast Discussion

.SYNOPSIS...A series of storm systems will affect the Silver State
through the middle of next week. The storm on Sunday and Monday
has the best potential for heavy snow and gusty winds will create
some blowing snow issues, making travel more difficult.


.SHORT TERM...Tonight through Monday. Radar mosaic is showing the
main precipitation core extending from Carson City northeast
through Elko County. Temperatures are not all that cold and rain
is the precip type back towards Lovelock and KWMC is above
freezing with vicinity showers. Elko is under a blanket of light
snowfall. KELY and Eureka are around the freezing mark with some
mixed precipitation type reported. Winter Weather Advisories
continue for all zones, expiring overnight and more snow is

Tonight. Winter Weather Advisories will continue. The low pressure
area off the Pacific Canadian coast is extending a trough axis
along the spine of the Sierras. This lobe axis will slowly move
east and showers will taper off west to east overnight. Northern
Nevada could generally pick up a couple more inches of snow
through this evening with road temperatures helping to melt it
off. Snow accumulation will be more significant across northeast
Nye and White Pine Counties, perhaps getting up to 3 more inches
of snow through the wee hours of Saturday morning. Low
temperatures will be in the teens and 20s.

Saturday through Saturday night. Low pressure off the Canadian
Pacific coast will drift to re-center off the Washington coast.
This action will yield a break between systems affecting the Great
Basin. Showers will continue with a dirty shortwave ridge over
Nevada proposed by the models. High temperatures will range from the
upper 20s to mid 30s. Low temperatures will be in the teens and

Sunday through Monday. A Winter Storm Watch is in effect for snow
and blowing snow for central Nevada and the Ruby Mountains. Low
pressure will drop south along the Oregon and northern California
coast, producing a rather intense diffluent flow aloft of the LKN
CWFA. The nose of a 160kt jet flow will pass over western Nevada.
Another surge of moisture will spread across the Great Basin,
partially intercepted by the Sierra-Nevada range which could
reduce snow amounts in the north. At this time, it looks like a
general 3-5 inches of snow for the valleys of northern Nevada with
higher amounts over central Nevada. Issued a Winter Storm Watch
for the southern half of the LKN CWFA due to the wind aspect,
blowing snow, and the prospect of a 5-9 inch valley snowfall event
with mountains getting a couple feet of snow. High temperatures will
range from the upper 20s to mid 30s. Low temperatures will be in
the teens and 20s.

.LONG TERM...Monday night through Friday

Medium wavelength trough over the western interior CONUS Monday
night will shift east through Tuesday and a narrow ridge will
replace it from the west. The ridge will broaden and deepen
through the remainder of the long term forecast, but with added
snow cover and dissipation of clouds, night time temps will
plummet again, and even day time sun won`t help much, with highs
in the 20s most places and low 30s in central Nevada. Lows in the
single digits and teens will drop to below zero and low single
digits by Friday.

Pops drop off quickly under the ridge, and winds will tend to


.AVIATION...Briefly VFR at times all sites, all sites will drop to
MVFR or IFR through 00Z Saturday. Also, KTPH and especially KELY
will likely have periods of blowing snow reducing visibility at
times. Mountain obscurations all sites, and en route.
