Area Forecast Discussion

.SYNOPSIS...You may see a few mountain showers around today and
Saturday but for the most part dry conditions will continue
through the weekend. There will be an increased chance for showers
Sunday night and Monday.

&&

.SHORT TERM...Today through Sunday. IR satellite imagery shows the
splitting nature of the next system approaching Nevada from the
west. A very dirty ridge of high pressure is spewing abundant
cloudiness into southern California while an upper level trough of
low pressure is moving towards the Pacific Northwest coast. A few
showers are already occurring over the Cascades in Washington
state. Some showers are expected as the upper trough moves inland
over the next couple days however no impacts are expected. Model
agreement is very good.

This morning. Dry conditions will continue all across northern and
central Nevada. High pressure will exit eastward to the 4-corners
area of the country. There is a small chance for a short-lived
temperature inversion.

Friday afternoon through Saturday morning. The upper level trough
will move onshore. Models have been persistent in portraying a
mere weak short wave brushing northern Nevada as the trough
disintegrates. The result...there may be some mountain showers as
it brushes northern Nevada. High temperatures will range from the
upper 20s to the upper 30s. Low temperatures will range from the
teens to the mid 20s.

Saturday afternoon through Sunday. A return to dry conditions is
expected. High pressure will re-build east of Nevada, providing a
southwest flow aloft of the LKN CWFA. Most times, this would mean
warmer temperatures however this time of year, the air is blowing
across the Sierra snowpack. Cold temperatures will continue. By
late Sunday, its possible that some showers will begin across far
western Humboldt County as the next system approaches. High
temperatures will generally be in the 30s. Low temperatures will
generally be in the teens.

.LONG TERM...Sunday Night through next Thursday.

The next system still on track to begin moving into Humboldt
County late on Sunday night and then quickly across the remainder
of Nevada on Monday. Snowfall amounts at this time look to be
up to an inch or so in the valleys, with about an inch to three
inches in the mountains. There may even be a rain/snow mix in
some of the lower valleys of Humboldt County. There may also be
some breezes on the passes and summits for Monday afternoon.
Ridging then looks to build in on Tuesday and Wednesday, bringing
the return of fair and warmer weather. Southwest flow moves back
in on Thursday ahead of another possible small system on Friday.
After the system on Monday, temperatures will rise into the 40`s
for most areas during the week and possibly even some 50`s could
be seen in Northern Nye County. Lows will be in the teens and the
20`s.

&&

.AVIATION...Look for VFR conditions for the next 24 hours.

&&

.LKN WATCHES/WARNINGS/ADVISORIES...
None.
