WINTER STORM WARNING

WINTER WEATHER ADVISORY

A warmer air mass (pineapple express) will move over the Northstate as early as Friday afternoon into the weekend as sub-tropical moisture will contribute to a good shot of rain.  Rain estimates give the valley between 2 and 4 inches of rain once all is said and done with higher amounts in the mountains.  One concern will be the potential for debris flows over burn scarred areas.  Otherwise, it will be welcomed rain with snow levels 6000 feet and higher.

It looks like drier weather for the beginning of next week with the long range forecast models hinting at some more rain by the end of next week.
