Next big rain to arrive Thursday, another for Christmas

Our pattern of about two major storms a week will continue through Christmas. From the National Weather Service:
Wet Pattern Thursday Through Next Week Will Impact Holiday Travel

Impacts
Slick roads from rain & snow
Chain controls, travel delays over the mountains
Localized urban and small stream flooding possible
Potential for debris flows on burn scars

Forecast Confidence
Medium

Timing and Strength
Several waves of rain/snow expected Thursday through Christmas. Current models suggest heaviest precipitation could occur:
Friday afternoon - Saturday afternoon
Late Sunday - early Tuesday
See graphic for potential precipitation amounts through Monday (NOTE: additional rain/snow will continue Tuesday into Christmas)
Snow levels will vary between 4500 to 6000 ft
Winds will be breezy to gusty at times

Weather Summary
An active weather pattern will bring rain & snow to NorCal starting Thursday and continuing through next week. With holiday traffic next week, this wet pattern will increase the chances for accidents & delays. This extended wet pattern will also enhance the possibility of localized flooding & burn scar debris flows.
