NOAA Forecast Discussion Excerpts:

.SYNOPSIS...

A series of cold fronts will produce gusty winds today and again
Wednesday. Below average temperatures are expected for much of the
upcoming week, with the coolest days most likely Thursday and
Friday. Light showers, with a dusting of snow in higher
elevations, are possible at times from Wednesday through Friday.

SHORT TERM...

The transition to a more active weather pattern with much cooler
temperatures and chances for showers (including a bit of snow
possible for the mountains) is still on track for this week, as
long wave trough digs into the western US.

* Winds:
In general, gusts of 35-45 mph with Sierra ridge gusts up to 75 mph
are expected for this afternoon and evening.

 * Precipitation: 
Precip amounts are not expected to be very significant, but some 
locations in the Sierra, far northwest NV/Surprise Valley, and 
the Basin and Range east of US-95 could receive around 0.10 inch. 
Snow levels may drop to near 7000 feet by late Wed night, although 
if any light snow accumulations occur, they are more likely to be 
confined to higher peaks.
