Area Forecast Discussion
National Weather Service Reno NV
245 PM PDT Sat Sep 16 2017

.SYNOPSIS...

Seasonable temperatures and dry conditions will prevail this weekend.
A series of cold fronts will produce strong gusty winds on Monday and
again Wednesday. Below average temperatures are expected starting mid
next week, with possible freezes and frosts in colder valleys late
week. Any precipitation will be in the form of very light showers.

.DISCUSSION...

* Series of mainly dry cold fronts projected into the region over the
  coming 3-5 days. No meaningful precipitation and no accumulating
  snow. Main impacts from these fronts: 1) periods of strong winds,
  2) well below normal temperatures returning.

* Associated with each frontal passage, first Monday into early
  Tuesday and second on Wednesday, winds aloft increase substantially.
  700mb flow nears 40-50kts with mixing up to about that level. Monday
  and Wednesday look to have the most widespread gusty winds with
  Wednesday being strongest, potentially a wind advisory scenario.
  These will be our first gradient wind events in many months, so time
  to secure those flying trash cans and summer outdoor furniture.
  Can`t rule out some fire weather concerns, especially east of Hwy
  395 into central Nevada where afternoon humidities will fall into
  the teens coupled with still abundant and re-drying grasses.

* Not entirely atypical for fall, temperatures will fluctuate quite a
  bit this coming week. Nice cool mornings and comfortably warm
  afternoons this weekend and Monday will cool starting Tuesday, with
  a more dramatic drop Thursday. Some very pronounced cold anomalies
  showing up in the GEFS/ECMWF late week into next weekend as cool
  trough over W CONUS remains in place. Likely at some point Friday
  or Saturday we`d see our first widespread frosts with freezes in
  typically colder valleys.

.AVIATION...

* Scattered to broken high clouds this afternoon will gradually clear
  overnight as upper wave passes by. No precipitation expected with
  VFR conditions prevailing through the weekend. Only exception to
  that is the usual VCFG near TRK Sunday morning.

* Light SE winds this afternoon will transition to slightly increased
  westerly winds Sunday afternoon. Stronger winds will arrive Monday
  as first in a series of cold fronts moves into the region. Looking
  at moderate southwest winds Monday (gusts 30-35kts) along with
  increased mountain wave turbulence. Potential for even stronger wind
  event Wednesday. Bumpy rides ahead.
