Area Forecast Discussion
National Weather Service Reno NV
216 AM PST Sat Nov 18 2017

.SYNOPSIS...

High pressure will bring a dry weekend. Nights will be cold with
near or slightly above average afternoon temperatures. Warm and
weak systems could bring light rain and very high elevation snow,
along with mild temperatures, next week.

&&

.SHORT TERM...

The main forecast change in the short term to ease back chances
for precipitation and precipitation amounts Monday and Monday night.

A ridge of high pressure has built over the region and will persist
through the weekend before weakening slightly on Monday as a very
weak system brushes by to the north over the Pacific Northwest.
Winds will remain generally light for the weekend, with near or
slightly above average afternoon temperatures falling off quickly
for cold nights.

High clouds will begin to increase on Sunday ahead of the
aforementioned weak system. The wave will flatten the ridge on
Monday, bringing light precipitation (due to warm air advection)
to portions of northeast California, the Sierra and northern
Nevada. Snow levels will be high at 8000-10000 feet and liquid
totals aren`t impressive so notable travel impacts are unlikely.
This system will bring a modest increase in wind, mainly for the
higher elevations. -Snyder/Dawn

.LONG TERM...Tuesday through Friday...
Overall, continued the drying trend in the long term as the ridge
looks to be strong enough to continue to deflect the systems into
the Pacific Northwest. The best chance at seeing any showers will
likely be in Northwest Lassen County and near the Oregon Border
Tuesday then again Friday.

With the ridge in place and southwest flow aloft it will be quite
mild with temperatures running 10 to 15 degrees above average for
late November. Overnight lows may be mild as well, but the unknown
is the amount of cloud cover. With the moist southwest flow into
the Pac NW, there could be plenty of clouds around keeping them
mild. However, clearing would likely result in lows near to
slightly above average.

&&

.AVIATION...
VFR through Sunday with some patch FZFG near KTRK the next two
mornings. Not much in the way of an impact now for Monday with the
system falling apart as it moves in. Still expect primarily VFR
with only isolated areas of MVFR CIGS north of Tahoe.

.REV Watches/Warnings/Advisories...
NV...None.
CA...None.
