.SYNOPSIS...

  breezy conditions.

* There is a 10-20% chance of showers south of Highway 50 for
  Tuesday. Otherwise, dry and breezy conditions will linger
  through the week.

* Temperatures will start to cool slightly Monday, and further by
  late week, although remaining 5-10 degrees above average.
  Temperatures return to well above average again next weekend.

.DISCUSSION...

* Temperatures will remain 10-15 degrees above average across the
  region today. Afternoon breezes will return today, with ridges
  seeing 40+ mph gusts and leeside valleys checking in with 20-30
  mph gusts. Monday will be a rinse and repeat weather day, with
  temperatures cooling only by a degree or two.

* Tuesday we will see the influence of the remnant tropical
  moisture currently situated near Baja California making it`s way
  to southern Nevada. Forecast soundings are showing PWAT values
  around 0.9 inches, which may result in a cloudy and overcast sky
  with a few showers embedded. Another possibility with lower
  confidence would be the case where we see enough breaks in the
  clouds to increase instability and produce storms. Chances are
  10-20% from US-50 to the south, into Mono, Mineral, Lyon and
  maybe even Alpine counties. Rain amounts should remain light,
  around 0.1 inches at most. Once this low pressure system is
  swept into the westerlies, it will move out over the Great Basin
  for Wednesday. There is a 15-20% chance for a light shower near
  the White Mountains for Wednesday, with potential for some
  embedded thunder. From Thursday on, expect widespread dry, warm
  and breezy conditions.

* As mentioned above, temperatures will cool only slightly late
  this week, with daytime highs still above average. The following
  weekend will bring back high temperatures ranging 10-15 degrees
  above average. Long range outlooks suggest the warm dry trend
  will be with us into the first week of July. HRICH

.AVIATION...

* VFR conditions will prevail over area terminals, with some
  density altitude issues due to the hot temperatures. Afternoon
  gusts of 20-25 kts will be found across area terminals.

* Monday will be a similar day to today, with VFR conditions and
  afternoon breezes returning. Tuesday a 10-20% chance for showers
  will arrive early afternoon for KMMH, with another chance for
  showers on Wednesday. HRICH

.FIRE WEATHER...

Dry and hot weather with afternoon breezes this weekend continues to
lead to an elevated fire weather risk across the region. Today a
period of afternoon gusty winds and hot and dry conditions will be
present for a 4 to 6 hours for far N. Washoe, Surprise Valley and E.
Lassen bringing near critical conditions. Conditions improve on
Monday and Tuesday as winds decrease.

Wednesday and Thursday appear to be the days of major concern when
near critical conditions are likely due to stronger westerly winds.
This comes after a prolonged period of well above normal
temperatures. Dry conditions will continue with min RH generally
below 20% in CA, and below 15% in NV, along with breezy afternoon
winds.

Conditions should improve towards the weekend with lighter winds
expected areawide. HRICH/Crespo
