.DISCUSSION...

Broad high pressure across the West will dampen today as weak low
pressure traverses the Pacific Northwest. Dry southwest flow will
overspread the region in response, scouring upper moisture and
reducing thunderstorm chances this afternoon. The most likely area
for isolated storms is from northern Lassen County into the Surprise
Valley and far northern Washoe County where odds reach 30-60%.
Strong outflow gusts will serve as the main concern, accompanied by
small hail, brief downpours, and lightning. A stray thunderstorm or
two cannot be ruled in Mineral County this afternoon, although far
lesser odds of 5-10% resides here.

Summer-like heat will continue through Wednesday, featuring daytime
highs in the 80s and 90s. However, today begins a steady cooling
trend that culminates in more typical 70 and 80 degree highs by
Friday. Breezy winds are expected each afternoon this weekend,
peaking on Friday and Saturday. These windier conditions may impact
travel and recreation, as well as elevate fire concerns across the
region (see Fire Weather discussion below). Otherwise, plan on
typical June warmth and dry weather this week and over the weekend.

.AVIATION...

Shallow fog may result in periods of IFR/LIFR conditions at KTRK
through 14-15Z this morning. A drier weather pattern settles in
today, result in widespread VFR conditions with breezy westerlies
(G20-30kts) in the afternoon. FL100 winds marginally increase to
around 25 kts throughout the day, which may be sufficient for low-
end LLWS and mountain wave turbulence impacts for Tahoe and Sierra
Front terminals this evening.

.FIRE WEATHER...

A ridge breakdown sequence that begins today will result in elevated
to locally critical conditions below 6000` each afternoon through
Thursday. Red Flag conditions are possible along the Sierra Front
and across western Nevada Friday and Saturday afternoons when winds
are strongest. As winds increase, there may be flare-ups of holdover
ignitions from recent lightning.

* Today through Thursday: RH reductions to 10-15% is expected this
  afternoon for elevations generally below 6000` with further drying
  supporting afternoon RH`s of 5- 12% from Wednesday into the
  weekend. While winds will likely remain below Red Flag criteria
  until Friday, SW/W gusts of 20-30 mph (think our typical zephyr
  breezes) will overlap with very low afternoon RH today through
  Thursday. Poor overnight recoveries will compound fire concerns
  across western Nevada where RH struggles to exceed 30-40%.

* Friday and Saturday: Winds will likely be strongest Friday and
  Saturday afternoons, elevating the fire weather threat into Red
  Flag conditions along the Sierra Front and much of western Nevada.
  There is still some uncertainty in the magnitude of the winds on
  both days, but confidence is increasing in seeing at least a 3-6
  hour period of critical conditions each respective afternoon.
