.SYNOPSIS...
Low pressure will bring cooler temperatures and increased wind
gusts up to 40 mph for Saturday. Cooler temperatures will persist
into the start of next week along with a chance of showers and
thunderstorms. A second low could bring gusty winds and a chance
of precipitation late next week.

&&

.SHORT TERM...

Low pressure near 40N and 130W will move into northern California
and Oregon tonight, then drift south into Nevada late Sunday and
Monday. Before this system arrives a few showers and thunderstorms
may develop north of Truckee-Fernley later today. Any storms that
develop could produce outflow winds up to 40 mph.

Winds will kick up as the low approaches with choppy conditions
on areas lakes for late tonight and Saturday. Most gusts will
remain near 30 mph, though gusts as high as 40 mph are likely in
wind prone areas across the eastern Sierra and western Nevada.
Those planning to head out on area lakes tomorrow will want to
use caution.

The chance for showers and thunderstorms will continue into early
next week as the low drifts about Nevada. Latest simulations are
showing a best chance for showers and storms on Sunday afternoon
north of US-50, with light showers possible for Monday as the cold
core of the low moves into central Nevada. Afternoon highs will
fall off into the 60s and 70s for Sunday and Monday, about a 15-20
degree drop from this afternoon.  Brong

.LONG TERM...Tuesday through Friday...

Low pressure will remain over the Great Basin on Tuesday although a
shortwave ridge of high pressure will move into northern CA. There
may be some marginal instability on Tuesday afternoon for a few
isolated showers, but right now only the GFS is showing this
potential.  We have raised the PoP south of Highway 50 to around
10%, but still left the mention of showers out of the forecast at
this time for Tuesday.

By Wednesday, low pressure will begin pushing into the Pac NW and
far northern CA with chances of showers and increasing winds. There
are still some slight discrepancies in the trajectory of the low
moving in, although the GFS is supported by its ensembles and the
GEM as well. We introduced a slight chance of showers (maybe even a
thunderstorm) for a few areas, mainly north of Susanville Thursday
and Friday.

As for winds, gusty conditions are possible Thursday afternoon and
into Friday as the low pressure tightens up the pressure and
temperature gradients. Cooler temperatures are likely beyond
Thursday as the cold front will bring temperatures back down into
the 60s for western NV. Hoon

.AVIATION...

An enhanced surface temperature gradient is likely to produce gusty
surface winds for areas immediately east of the Sierra today with
gusts approaching 25 kt for KRNO...KCXP...KMEV and KMMH early this
evening. Gusts are likely to be a bit lower for KTVL and KTRK. An
approaching trough of low pressure will also aid in developing
isolated showers and possibly a few thunderstorms north of I-80
today.

As this low gets closer Saturday the shower and thunderstorm
coverage will increase and drop a bit farther south to near the
Highway 50 corridor.

Overall...VFR conditions are expected through Saturday. Turbulence
is likely near thunderstorms. 20/Hoon
