Winter Weather Advisory: the National Weather Service forecast is calling for very low overnight temperatures in the East Bay and the possibility of snow down to 1200 feet or lower. We could see some snow on Mt Diablo.
In addition, temperatures overnight will get down to the freezing point. This could create very slick conditions for the morning commute. Drivers, cyclists, and pedestrians are encouraged to plan for some extra time and use some additional caution when out and about Tuesday morning
