.DISCUSSION...
Dry and mild weather with light E/NE breezes persist through the
weekend. Winds along the Sierra crest will become breezy at times
this weekend. Low pressure brings a low chance of rain and isolated
thunderstorms to the Sierra south of Tahoe on Monday. Warm and dry
weather prevails elsewhere. A breezier weather pattern is favored
late next week into next weekend with low chances of rain and storms.
Note: Thunderstorms imply gusty and erratic winds.
Note: Mixing Heights are in feet above ground level of the valley floors.
