.KEY MESSAGES...

* Near average temperatures and drier conditions with light breezes
  will persist through Friday.

* Another weekend storm will impact the Sierra and western Nevada
  bringing an increased likelihood of cooler conditions, gusty
  winds, rain and mountain snow showers.

&&

.DISCUSSION...

* Today: A quick-moving sneaky shortwave will drop through the
  region today bringing a 10-15% chance for showers and
  thunderstorms to the eastern Sierra this afternoon and evening.
  Otherwise, light northwest breezes will keep it feeling coolish
  today.

* Thursday-Friday: Brief high pressure returns across the West
  through Friday with temperatures warming back to around average
  for mid May. We`re looking at high temperatures in the mid-70s for
  western NV, eastern Lassen, and lower elevations of Alpine and
  Mono counties. For the eastern Sierra communities, highs will be
  in the low to upper 60s.

* Another Stormy Weekend: Brace yourselves for more weather whiplash
  as the next spring storm approaches the Sierra and western Nevada.
  Best to plan for increasing winds, valley rain showers, mountain
  snow (esp above 8000 ft), and colder temperatures. The first round
  arrives on Saturday with precipitation spreading across much of NE
  CA and western Nevada by midday Saturday. The best chances (50-
  60%) for showers will be in the Tahoe region northward with lesser
  chances toward Mono County with a 20-40% chance. Snow levels will
  be around 8000 feet, so plan on snow showers in the higher
  elevations. The winds may be the primary hazard with strong west,
  northwest winds on Saturday switching to gusty northerly winds on
  Sunday. While it may be quite breezy across much of the Sierra and
  western Nevada, there are some strong wind signals for the
  southern Sierra Front (Topaz Lake area southward to Mammoth). If
  you plan on being outdoors this weekend, particularly in the
  mountains for any adventures be sure to pack plenty of supplies to
  battle the wind, colder temperatures, and shower potential.
