Special Weather Statement
Statement as of 3:28 PM PST on November 8, 2009


... A colder storm could affect the region by Wednesday...

Low pressure currently over the Gulf of Alaska will move into
northern California by Wednesday. A cold front may bring a period
of moderate to heavy precipitation sometime between Wednesday
afternoon and Wednesday night. Gusty south to southwest winds over
30 mph are possible ahead of the front Wednesday... especially in
the mountains. Gusts over 50 mph may develop over higher mountain
passes.

Rain may move into the northern Sacramento Valley by Wednesday
afternoon... and spread across the entire region Wednesday night.
In the mountains... rain and snow may move into the Lassen park area
and Shasta County mountains Wednesday afternoon... and shift into the
west slopes of the Sierra Wednesday night. Occasionally heavy
showers are possible near the cold front as it moves south across
the region.

Snow levels could drop below 6000 feet Wednesday night... meaning this
storm has the potential to have a high impact on travel in the mountains.
Colder air may continue to spill into the region Thursday. Valley rain
and mountain snow showers could continue into Thursday morning
before tapering off by late Thursday afternoon.

If your plans call for travel into the Sierra or Lassen park area
Wednesday and Thursday... be prepared for winter driving conditions.
Monitor the latest National Weather Service forecasts for updates
and future statements about this developing storm.
