.DISCUSSION...

This morning we will see clear skies and light winds to start off
the day, but clouds will gather later today. These could contain
some showers (10% chance) for the area from Susanville to Gerlach.
Otherwise, most areas will remain dry. As a trough extending from
roughly Alberta province in Canada, and draped across the Great
Basin exits, and a low positioned off the SoCal coast join
together, chances for showers (10%) will return for Monday along
the Sierra Crest.

Tuesday is looking dry and mild as the trough moves eastward, with
near average temperatures settling in across the region. Wednesday,
another low pressure system will drop in along the British Columbia
coast, bringing precipitation along the Oregon border (25-35%
chance) and wind gusts that will approach 30 mph for western Nevada
valleys. That activity is short-lived as the trough is swept east
quickly, bringing another drier, yet cooler day for Thursday with
the exception of afternoon chances (10-15%)for showers in Mono
County.

Now to take a forward glance to the holiday weekend, where ensembles
are showing yet another brush-by trough to drop across the Pacific
Northwest. For now, the ensembles agree there will be another
trough, roughly arriving on the heels of the exiting trough. The
depth of the trough will dictate how far south the precipitation
chances will be, but for now the Sierra crest, along the Oregon
border and out over the Basin and Range will see a 10-15% chance
for afternoon showers and storms to appear. Initial indications
are highlighting Saturday for the most widespread opportunity to
see a shower pop up.

* VFR conditions across area skies today, with NNW winds around 10
  kts this morning becoming WNW at 15-20 kts with gusts to 25
  possible. Ridges along the Sierra crest may gust 25-30 kts.

  bringing low-end chances for showers and storms along the
  Sierra. Chances are less than 20%, but cannot rule out isolated
  showers this week.
