.DISCUSSION...

* Temperatures/Wind: Temperatures will trend down this weekend as
  an upper level trough moves through the western US. Temperatures
  today will reach the mid-90s for a majority of western NV,
  eastern Lassen County, and the lower elevations in Mono County.
  By Sunday, these aforementioned areas will see afternoon
  temperatures mainly in the upper 80s to low 90s. Most of the
  eastern Sierra valleys will be primarily in the upper 70s to
  low-80s. While not as hot as the last few days, these readings
  are still upwards of 10 degrees above average for early June. We
  can expect typical Zephyr winds each afternoon for western NV,
  with gusts each afternoon upwards of 25-30 mph. Otherwise,
  there are no major winds.

* Thunderstorms: High resolution models continue to show that the
  best chances (30%) for thunderstorms today will be south of
  US-50, and east of US-95 in the inner basins and ranges in
  western Nevada. Primary concerns with the storms in these
  locations will be gusts of 30-40 mph, small hail, and frequent
  lightning. Locally heavy rainbursts within the storm cores can`t
  be ruled out. Thunderstorms are possible (20%) this afternoon in
  northern Lassen and Washoe counties near the OR border. These
  storms have the potential to become strong this afternoon.
  These same aforementioned areas will see additional chances for
  showers and thunderstorms on Sunday, with similar impacts.

* Next Week: For the upcoming week, model ensembles still indicate
  a ridge building across the western US with a cutoff low
  drifting off the southern CA coast. Temperatures will trend up
  across the region from Tuesday through Friday, with temperatures
  once again returning to 15 degrees above average. Precipitation
  chances look low given the track of the cutoff low pressure.

  westerly winds this afternoon with gusts up to 20-30kts for

  best chances south of US-50 and east of US-95 in NV. There is

  KTVL, KMMH). Main concerns from storms will be winds up to
  35kts, small hail, and lightning. -McKellar
