Hamilton City, California

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

A weak weather system will move through the Shasta County mountains
and Lassen park area tonight with scattered showers. Impacts from
this system are expected to be minimal as snow levels will remain
near 7000 feet tonight.

A colder low pressure system over the Gulf of Alaska will
approach California Wednesday and Wednesday night. This storm
could drive a cold front with moderate to occasionally heavy
showers from Sacramento to Modesto Wednesday night into Thursday
morning.

In the mountains... rain and snow may return to 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 Wednesday night into early Thursday morning.
Snow levels could drop below 6000 feet Wednesday night. This storm
has the potential to have an impact on travel in the mountains.

There is some uncertainty about how much snow will fall in the
mountains because some of the energy from this storm may remain
offshore. There is a possibility of snowfall down to 5500 feet
Wednesday night and Thursday morning. Occasional moderate to heavy
snow showers and gusty winds could make travel difficult over
higher mountain passes during this time.

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