.KEY MESSAGES...

  and near average temperatures expected through Friday.

* Another low pressure system will impact the region this weekend,
  brining an increased likelihood of cooler conditions, gusty
  winds, rain and mountain snow showers.

.DISCUSSION...

* For today, we`ll continue with below average temperatures under
  a chilly northwesterly flow. There is a subtle short-wave
  currently at ~50N/135W that will ride southward along the
  exiting upper level low. This feature will move into the region
  by the late morning into the early evening. As a result, the
  eastern Sierra has a 15% chance for light showers, with a 10%
  chance for thunder. With the recent precipitation, areas of fog
  and low stratus may form by the morning for Sierra valleys.

* A weak ridge builds back into the western US through Friday.
  Temperatures for Thursday and Friday return to average for mid-
  May. For reference, that`s mid-70s in western NV, eastern
  Lassen, and lower elevations of Alpine and Mono counties.
  Meanwhile for the eastern Sierra communities, normal
  temperatures for mid-May range from the low to upper 60s.

* Our return to late spring will be short lived, with ensemble
  solutions all pointing to yet another system just in time for
  the weekend. It`s almost like the jet stream knows your weekend
  plans! While it`s still a bit far out to get exact details,
  latest blended guidance has increased precipitation chances from
  prior forecasts, especially on Saturday. For Saturday, we`re
  looking at likely (>60%) chances for precipitation across much
  inner basins and areas along and north of US-50 in western NV.
  The Reno-Carson City-Minden area has a 35-45% chance of showers.
  For the eastern Sierra, the best chance (50-60%) for showers
  will be mostly for Tahoe area northward while Mono County has
  20-40% chance for precipitation. Snow levels look high, mostly
  above 8,000`. The signals for gusty winds have remained similar
  to the prior forecast, with 35-45% chance for westerly gusts
  over 35 mph. Enjoy the few days of late spring and stay tuned
  for the weekend. -McKellar
