.DISCUSSION...

* High pressure centered over the Desert Southwest will gradually
  expand into the forecast area through Tuesday. This will allow
  for a warming trend, with temperatures returning to the mid to
  upper 90s for much of western NV and eastern Lassen County. We
  could even see near the century mark for the Chalfant Valley and
  isolated valleys in the NV Basin and Range. High temperatures
  for the eastern Sierra communities will warm mostly into the
  upper 70s to 80s. With the hot temperatures, widespread Moderate
  HeatRisk is likely for a majority of western NV, with a few
  isolated Major HeatRisk areas in the inner Basin.

* At this moment, blended guidance shows Tuesday as the hottest
  day this week. The reason is that on Wednesday, a weak trough
  moves into the Pacific Northwest. This feature will start to
  push the aforementioned high pressure back to the southeast. By
  Friday, another potentially stronger trough is poised to moved
  into the Pacific Northwest. The ensembles are starting to show
  better agreement on the evolution of this feature compared to
  prior runs. At this time, gusty winds start to increase as early
  as Thursday. Winds are the strongest on Friday, with likely
  (60-90%) chances for winds greater than 35 mph. These winds
  combined with the hot temperatures and dry conditions will lead
  to fire weather concerns Thursday into Saturday. There are other
  additional impacts to aviation and recreation, as well as low
  10-20% chances for showers and storms near the OR border on
  Friday. Winds remain strong on Saturday, then finally start to
  decrease on Sunday. Temperatures during this time frame with
  trend cooler, with afternoon readings between 5-10 degrees below
  average for late June. We will be riding the weather roller
  coaster this week! -McKellar
