Synopsis
Low chances for light showers or sprinkles continue into the morning
hours today, generally from interstate 80 northward. Winds will taper
down tonight. Gusty winds and some fire weather concerns are expected
to return Saturday, with warmer weather and lighter winds for next
week.

Short term
Mainly minor adjustments were made to the existing forecast. Light
showers are moving through the region this morning, mainly north
of interstate 80, bringing some light rain accumulations. These
showers are expected to taper off through the late morning hours.

Winds will slow as well this evening as troughing exits the region.

Some light breezes can be anticipated for Friday with cloud cover
increasing as another, stronger wave approaches the region. This
trough has better jet support (~120kt jet max) and should lead to
gusty winds for the region by Saturday, especially along the ridges
and portions of the sierra front. Currently, the forecast for wind
gusts ranges from around 30-40 mph between the highway 50 and
interstate 80 corridor, to 40+ mph north of interstate 80. Highest
current potential gusts are around 50-60 mph, supported by 50-55kt
700 mb model winds, for the surprise valley and very northern
washoe county areas. Models are still settling on a track for the
surface low so there is still room for adjustments that would
have implications on the strength of winds across the region.

With dry conditions in place and wind gusts in excess of 40 mph,
concerns for fire weather are increasing; please see the fire
weather discussion below for details. Otherwise, today and
tomorrow are good days to secure loose outdoor items and holiday
decorations. Other hazards include turbulence for aircraft,
potential for crosswinds along north-to-south routes that could be
an issue for high profile vehicles (looking at you, washoe
valley), and blowing dust off of area sinks.

Precipitation chances for Saturday have been more limited to north
of interstate 80 as latest models track the wetter portion of the
wave north and east of the sierra and western nevada. There could
still be a few isolated showers as far south as highway 50, but
highest precipitation chances will generally be along and north of
a susanville to gerlach line. While chances of rain will be
increasing north of this line, QPF still looks rather meager in
the 0.05-0.25" range. Boyd

Long term Sunday through Thursday...

high pressure builds over northeast california and western nevada
next week. This will bring a warm up with highs in the upper 60s to
upper 70s (about 10 or so degrees above average) by Tuesday.

Wednesday, a disturbance will move by to the north of the region.

While the wave currently looks too far north for precipitation, it
is currently projected to push a dry front through for an increase
in northerly flow along with a slight cool down for Wednesday and
Thursday. -snyder

Aviation
An upper trough axis will pass over the sierra, northeast
california, and western nevada early this morning, with a frontal
passage before sunrise. This is bringing strong westerly winds over
ridges in the sierra and western nevada, with recent observations
showing gusts 60-100 mph. This is likely bringing significant
turbulence over and downwind of the sierra with pocket of llws where
surface winds have dropped off and in channeled terrain (such as
near ktvl). A few showers (snow levels 7000-8000 feet msl) in the
northern sierra and across northeast california and far northwest
nevada this morning may bring some high elevation terrain
obscuration.

Southwest-west winds gusting 25-35 kts this morning will switch to
west-northwest this afternoon with gusts mostly easing down to 20-25
kts. Another trough is forecast to bring another round of gusty
winds on Saturday, possibly up to around 25-35 kts. -snyder

Fire weather
Winds will remain breezy today with gusts 25-35 mph, but overall
humidity values will be higher as well. One possible exception is
southern portions of mineral and mono counties, including the us-6
corridor from benton to bishop, where humidity values could remain
or dip into the teens this afternoon.

For Saturday, an upper level trough will sweep across extreme
northern nevada providing strong winds with little or no
precipitation, except north of susanville and gerlach where wetting
rains will be possible. In general, peak wind gusts 30-45 mph are
possible, particularly north of highway 50. Humidity will however
be on the increase which may decrease fire weather concerns.

Areas across mineral and southern mono counties, however, may see
a potential for isolated critical fire weather conditions with
minimum humidity values 15-20%. -snyder fuentes
