.SYNOPSIS...

* Dry conditions will prevail through next week.

* Temperatures will remain near average, but brief cooling with
  gusty ridgetop winds is possible late Sunday and Monday.

* Longer range guidance brings a potentially colder weather
  system into the region by the January 25-26 weekend.

.DISCUSSION...

* A weak cold front moved through the region on Friday, ushering
  in a very dry airmass. We also had a slight increase in ridge-
  top winds and finally a dissipation of our persistent
  inversions. With the passage of the aforementioned front,
  temperatures today will end up 5 to 15 degrees cooler compared
  to Friday. Winds will be lighter today with mostly sunny skies
  and continued dry conditions. Temperatures will increase an
  additional 5-10 degrees on Sunday ahead of the next system.

* Another inside slider is still on track to arrive late Sunday
  night into Monday. The ensembles show that a very dry airmass is
  poised to move into the area, with PWATs below 0.10" (which is
  near the record driest for that date). Thus, no precipitation
  is anticipated with this system. What we will see is an increase
  in east to northeast ridge-top winds (gusts 50-60 mph) and a 10
  degree drop in temperatures. This may lead to choppy waters on
  Lake Tahoe for Monday, possibly needing an advisory.

* Ridging returns from Tuesday through much of the remainder of
  next week. As such, temperatures during this period will
  increase above seasonal averages. We`ll have light winds through
  this time frame, and the return of inversions with poor
  dispersion.

* By next Saturday into the start of the following week, ensembles
  are still trying to break down the ridging pattern. But, there
  is low confidence with some solutions showing a slight ridge
  while other solutions show a deep trough. -McKellar

.AVIATION...

* VFR conditions will prevail across the region through the
  weekend with light surface winds and limited cloud cover.
  Valley inversions will continue to support areas of urban haze
  and slight reductions in slantwise visibility during
  overnight/morning hours for most days in the upcoming week,
  mainly near KRNO.

* Mainly W-NW Sierra ridge wind gusts around 30 kt through this
  weekend may produce occasional mountain wave turbulence. These
  ridge winds then increase with potential for stronger NE-E gusts
  up to 50 kt late Sunday night through Monday, leading to more
  turbulent conditions especially near and west of the Sierra
  crest. -McKellar
