.KEY MESSAGES...

* Above normal temperatures continue through next week.

* Brush by cold front brings light showers late tonight and breezy
  periods Saturday.

* Streamflows will increase as a result of warming but no
  appreciable flooding expected.

&&

.DISCUSSION...

* Fast moving upper wave and attendant cold front will bring
  isolated showers to NE Cal overnight into early Sat AM. HRRR shows
  100-200 elevated CAPE with HREF indicating 10-30% odds for t-
  storms from Lassen NP to Susanville/Alturas.

* Same front will bring breezy N/NW winds on Saturday, mainly for
  western and northern NV. Most breezes should be on the order of 20-
  30 MPH gusts. NBM shows 20-30% probability for peak gusts over 45
  MPH in areas such as Gerlach, Lovelock, and Fallon. Blowing dust
  could be an issue Saturday given recent dry weather. Pyramid and
  Walker Lakes will get choppy Saturday afternoon/evening.

* Temps will take a slight dip this weekend, but warm back up to
  well above normal next week. Starting Monday NBM shows meaningful
  probabilities for max temps above 80 in W Nevada (60% or higher).
  This coupled with above freezing lows in mountains (e.g. Sonora
  Pass 75% odds for lows above 35), should yield increases in
  snowmelt driven streamflows most of next week. Flooding is
  unlikely, but any flooding should be minor and brief, as temps are
  warm but not "heatwave warm".

* Deterministic models are showing some weak waves moving into
  CA/NV next week. One in particular on Tuesday seems to have more
  potential of kicking off showers over the high terrain, and
  perhaps a t-storm or two. 10-20% odds but worth watching.

.AVIATION...

* VFR conditions for the most part through the weekend.

* Brush by cold front will bring breezy W/SW winds this afternoon
  and N/NW winds on Saturday. Mostly gusts 20-25 knots. Could be
  some blowing dust visibility restrictions between NFL-LOL-WMC
  Saturday. Flow aloft sufficiently fast for LLWS and mountain wave
  turbulence tonight between 6z-18z, mainly in the Sierra.

* Latest HREF/HRRR showing potential for a band of showers and
  possibly t-storms from Lassen Peak to SVE/AAT late tonight between
  6z-15z. Could see localized MVFR conditions, about a 20-30%
  probability.
