.KEY MESSAGES...
* A series of disturbances will roll through the Western US this
  week, bringing isolated showers to the Great Basin and breezy, dry
  conditions elsewhere in the region.
&&
.DISCUSSION...through Sunday.
Late morning satellite imagery shows building cumulus clouds along
the ridges of the southern Great Basin and southern Sierra. A
shortwave trough approaching the central California Coast will
support a few showers and isolated thunderstorms (20 to 30 percent
chance) this afternoon and again tomorrow afternoon over the
mountains surrounding the far northern Owens Valley and across
Esmeralda and central Nye Counties. Outside of these areas, no
precipitation is anticipated, though breezy south to southwest winds
of 15 to 25 mph can be expected.  As this trough shifts east by mid-
week, upper-level southwesterly flow will set up, pushing any
remaining moisture out of the region. A second trough is forecast to
move into western US late in the week. While details regarding
timing and intensity remain uncertain, breezy winds and cooler
temperatures are likely to accompany it. These cooler temperatures
should persist as long-term guidance shows this trough-y pattern
continuing through the weekend and into early next week.

significant weather impacts are anticipated through tonight, with
light winds following typical diurnal patterns. While a slight
chance remains for brief periods of 10 to 12 knot winds, the
probability of this has decreased to 10 to 20 percent. Gusts to
around 20 knots are more likely tomorrow, generally between 30/18Z
and 01/03Z. VFR conditions will prevail through the TAF period with
FEW to SCT clouds with bases AOA 10kft AGL.
For the rest of southern Nevada, northwest Arizona and southeast
California...For the 00Z Forecast Package...Most locations will
continue to experience light breezes that follow typical diurnal
patterns through tonight. The exception will be the Owens Valley and
southwestern Great Basin where gusty south winds of 20 to 30 knots
are possible into the early evening. A few showers and isolated
thunderstorms also remain possible in these areas. Winds and any
convective activity are expected to subside after sunset. Aside from
the convection mentioned above, VFR conditions will prevail through
the TAF period with FEW to SCT clouds with bases AOA 10kft AGL.
