.DISCUSSION...

* Weak ridge across the Sierra and western Nevada will bring warmer,
  near average temperatures for the season. Plan on highs in the mid-
  70s for western NV, eastern Lassen, and lower elevations of Alpine
  and Mono counties. For the eastern Sierra communities, highs will
  generally be in the low to upper 60s. Typical winds are forecast
  each afternoon and evening with gusts 15-25 mph. Chances for
  showers will be relatively low (10-20%) across the Eastern Sierra
  this afternoon and then late tonight into early Friday across
  northern NV and far northeastern CA as a quick shortwave swings
  through. The lower end shower chances continue on Friday along the
  Sierra Front stretching from Susanville southward to the eastern
  Sierra.

* Shower potential continues to ramp up from Friday night into
  Saturday as another weekend storm barrels through the Sierra and
  western Nevada. Widespread precipitation will be possible with
  snow down to around 8000 feet. The best wetting rain (>0.10")
  chances stretch from far NE CA and much of western NV with a 50-
  80% chance for precipitation. That potential tapers downward to 25-
  45% for Mono County, the immediate Reno-Carson City-Minden area,
  and southern Lyon and Mineral counties. Snow accumulations will be
  difficult to come by on area roadways, but above 8500 feet there
  could be a couple of inches by Monday morning.

* Stronger winds are on the table for this weekend as well with
  west to northwest winds on Saturday switching to gusty northerly
  winds on Sunday. Areas south of Highway 50 are still showing a
  decent signal (ECMWF EFI) for anomalously strong winds on
  Saturday, then transitioning to more widespread wind signal for
  Sunday that extends from far NE CA and NW NV southward through
  the Highway 395/Interstate 580 corridor down through southern
  Lyon and Mineral counties. The strong winds on Saturday appear
  to be driven more by upper level strong winds, while the winds
  on Sunday are surface gradient driven with some upper level
  support. In simple terms, it is going to be windy on both days
  with impacts to travel and recreation likely. Widespread wind
  gusts 35 to 45 mph will be likely with wind gusts exceeding 50+
  mph for wind prone areas. Temperatures will plummet with and
  behind these strong winds on Saturday, so be ready to bundle up
  for a day or two.

* Long-term ensemble solutions continue to highlight the return of a
  ridge pattern, with temperatures increasing back above average
  with dry weather next week.

.AVIATION...

*  Winds will be light and mainly from the west today, with gusts
   up to 20 kts at all area terminals.

*  Areas of IFR in patchy FZFG are possible at KTRK overnight
   thru 16z Friday morning.

*  Another storm is on the horizon for the weekend with more
   winds, valley rain and mountain snow. There is an increased
   trend for LLWS and mountain turbulence concerns starting early
   Saturday morning continuing into Monday morning. -McKellar
