For Thursday, a Dense Fog Advisory is in effect until noon for the Sacramento and San Joaquin valleys. Less than 1/4 mile of visibility is expected, with some local areas possibly getting close to zero visibility.

However, a more significant system is expected on Christmas Day.

The National Weather Service says a quarter to half an inch of rain is expected in the valley with Friday’s round. Heavy snow is also expected to develop, with forecasters saying 8-18 inches is possible across the higher mountain passes.

Up to 2 feet of snow could fall over peaks Friday through Saturday, forecasters say.

Drivers who are heading up to the mountains should prepare for winter driving conditions.
