.DISCUSSION...

A handful of showers and thunderstorms continued late into the
evening and early morning across western Nevada. Primarily the
storms produced outflow wind gusts in the 40s, moderate blowing dust
near Fallon, and quite the lightning show east of Reno! A few
outflows may continue to keep breezes up overnight, particularly in
the Basin and Range. Showers are slowly moving east of Lovelock and
Fallon along the Interstate 80 corridor as of midnight.

The rest of the day is projected to be relatively dry in comparison
to the past week with little to no showers forecast to pop this
afternoon and evening. Plan on increasing dry, southwesterly flow in
response to a Pacific Northwest trough slowly inching closer to the
West coast. The trough will bring a pattern change to the Sierra and
western Nevada over the next week with breezy winds and cooler
temperatures. The weekend breezes paired with dry conditions may
produce brief, localized critical fire weather conditions in the
afternoons. Monday remains the favored day for peak winds with
widespread chances (50%) of gusts exceeding 30 mph. Higher humidity
values on Monday (in response to the dropping temperatures) will
help to limit fire concerns, but we can`t rule out holdover fires
flaring-up in response to the stronger winds and dry conditions.

Temperatures continue to drop midweek next week with widespread
below average values for the region. Hello sweater weather! Shower
and storm chances return to northern areas starting on Monday, but
spread across the Sierra Front and the rest of Western Nevada for
late Tuesday into Wednesday. The slow progression of the trough will
result in several days of storm and shower chances next week. It`s
hard to pinpoint which areas to target for the best precipitation
potential, but plan on it being much cooler with increased
precipitation chances areawide. It still appears to be cold enough
for snow flurries in the High Sierra too! By the end of the week
into the weekend, the trough finally ejects eastward allowing for a
quick warmup and dry period.

.AVIATION...

* Dry conditions with typical afternoon breezes resume today as
  shower and thunderstorm chances largely disappear for the weekend
  under dry southwest flow.

* Wildfire smoke from nearby fires will continue to impact slantwise
  visibilities during the mornings and evenings especially for KMMH.

* Bigger pattern change on the horizon as a trough pushes into
  the region gradually through next week. Plan on increasing west
  to southwest flow this weekend with peak surface wind gusts up
  to 25 kts today and Sunday. FL100 winds will also meander
  between 25-30 kts starting this afternoon through Sunday.
