.DISCUSSION...

A trough off the west coast will move into central CA today and
eventually into southern NV as a closed low on Monday. Ahead of
this feature, high resolution models and blended guidance shows a
10-15% chance for light showers in Lassen and northern Washoe
counties this morning. These showers then spread into the rest of
the inner basin and ranges this evening. Southwest winds gusts
today will range from 25-30 mph in western NV and 35-45 mph on the
ridges. We will be cooler today, with high temperatures in the
mid-70s in western NV and low-60s for northeast CA and the eastern
Sierra communities.

Expect reductions in air quality primarily down the US-395
corridor from Walker to Bridgeport. However, said air quality
reductions are dependent on smoke production. For details on air
quality, please visit www.fire.airnow.gov.

As the low tracks into southern NV today into Monday, we`ll see
the best chances for showers in the eastern Sierra and western NV.
Current blended guidance shows a 20-50% chance for precipitation
tonight through Monday afternoon. Total accumulations for this
system will be light, generally 0.10" or less. There remains a
40-60% chance to see at least 1" of snow for elevations above
9,000 feet in Mono County.

A ridge pattern returns Tuesday through the end of next weekend.
Temperatures will trend between 4-8 degrees above average by
Wednesday. Dry weather with light winds will prevail during this
timeframe. -McKellar
