.Synopsis...

Showers and thunderstorms are possible in the valley and snow to
elevations at and above 5500 feet.

.Discussion... (Today through Friday)

Water vapor imagery during the early morning hours showed a dry
pocket of stable air over the west coastal states. The upper
level ridge of stable air will bring sunny conditions and near
normal temperatures across the forecast area today. A small upper
level disturbance of low pressure will slide south from the
Pacific Northwest into NorCal Wednesday.

The upper level system on Wednesday will bring unstable
atmospheric conditions to the valley, which will result in chances
for showers and thunderstorms. Higher elevations above 5500 feet
could see snow Wednesday. Some model forecasts indicate the upper
low deepening over the Great Basin, which will bring some
lingering precipitation over the Sierra on Thursday.

Dry and sunny weather will return to the forecast area towards
the end of the work week with another area of stable air making
landfall Thursday night into Friday. High temperatures could
possibly rise between 5 and 10 degrees above normal.

.EXTENDED DISCUSSION... (Saturday THROUGH Tuesday)

weekend as well. High temperatures will near the 90 degree mark in
the Valley by Sunday with widespread 90s (10 to 15 degrees above
