.DISCUSSION...

A quiet weather period will be in store with seasonable temperatures
and breezy east winds through Saturday. Highs will be in the
mid-50s across western Nevada (mid 40s Sierra valleys) this
afternoon before warming about 10 degrees on Saturday. Additional
warming into the low 70s for W.Nevada and near 60s for Sierra
valleys are expected for Sunday as light westerly breezes return.

A quick moving shortwave trough will push through the region late
Sunday into Monday which will begin increasing ridgetop wind gusts
to around 80 mph with lower Sierra and western Nevada seeing
afternoon wind gusts of 30+ mph. The best chances (40-60%) for
precipitation remain in western Lassen County, Surprise Valley,
and far northern Washoe County. These areas have around at 40-50%
chance for at least 0.10" of liquid. Snow levels remain above
7,000`, so snow impacts are very limited. This trough will also
provide about 4-8 degrees of cooling.

High pressure will then take hold with the main impact being a
steady warming trend with high temperatures returning to the mid
and upper 70s by mid-week with mid 60s for Sierra valleys. As the
high pressure center shifts eastward by Friday, temperatures will
cool back into the lower 70s across western Nevada which could
allow for increased westerly breezes by next Friday and Saturday.
