... A colder storm could affect the region Wednesday into Thursday...

A weak system will move through the area tonight into Tuesday
bringing a chance of precipitation... mainly over the mountains north
of Interstate 80.

A little stronger and colder low pressure system currently over
the Gulf of Alaska will move into northern California 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 by Wednesday afternoon... and shift
into the west slopes of the Sierra by 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 impact travel in the mountains
Wednesday night into early Thursday with snow possible over the
mountain passes. Valley rain and mountain snow showers could
continue into Thursday morning before tapering off by 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.
