.KEY MESSAGES...

* Dry and mild weather with cold mornings will prevail through
  Thanksgiving.

* Morning inversions will produce hazy skies and reductions in air
  quality for lower urban valleys through midweek.

* It is increasingly likely that cooler, unsettled weather returns
  this weekend into early next week.

.DISCUSSION...

A quiet weather pattern is in store through the Thanksgiving
holiday as a ridge of high pressure intensifies across the
region. This will result in continued dry conditions, periods of
high clouds, light winds, valley inversions, and steadily warming
temperatures. Strengthening valley inversions could result in
reductions to air quality in lower valleys as wind and valley
mixing remains light.

Expect chilly mornings with lows in the 20s and 30s for most
areas except for teens in colder Sierra valleys. Afternoons will
be seasonably mild as highs reach into the upper 50s to low 60s
for Sierra and W.Nevada valleys. Thanksgiving day looks to be the
warmest day of the week with highs near the mid-60s, particularly
for communities from Reno to the Carson Valley.

A transition to a cooler, breezier pattern is likely by the
weekend as an amplifying ridge over the eastern Pacific allows
colder, slider-type shortwave troughs to drop in from the
northwest and deepen over the western U.S. The main uncertainty is
precipitation potential, as ensemble clusters remain split on the
exact track of these shortwaves. A more inland (slider) path
would favor cooler temperatures but lighter precipitation. Current
trends lean drier, with only about a 20% chance of up to 0.25 of
liquid equivalent in the Sierra over a 48-hour period, and
overall 20-30% chances for rain and snow showers across the Sierra
and western Nevada from Saturday through Sunday. Fuentes

.AVIATION...

High pressure will maintain VFR conditions and light winds
through the holiday. Patchy FZFG may induce IFR/LIFR conditions at
KTRK this morning. Hazy skies from valley inversions may reduce
slantwise visibilities through midweek.
