What happened

The episode as NWS STO wrote it up.

A strong low pressure system brought strong winds to the Sierra Nevada, the foothills, and the Valley. Butte County received significant wind damage, with 2 fatalities caused by falling trees. A fallen tree also caused a fatality and several injuries in Shasta County. Multiple fallen trees caused damage to homes in the Motherlode foothills and in the Sacramento metro area. Fallen trees and branches also caused power outages, with 344,000 customers across northern California impacted. The storm dropped several inches of snow at higher elevations, causing traffic slowdowns and chain controls over the Sierra passes. Strong winds and cold temperatures also combined to bring wind chill temperatures well below zero for the higher Sierra, impacting outdoor recreation.

1016 PM PST Mon Dec 29 2014

.Synopsis...
Cold upper trough will bring a threat of snow showers over the
mountains tonight into Tuesday. Strong gusty north winds develop
Tuesday with breezy conditions continuing Wednesday. Decreasing
wind Thursday with dry weather into the weekend. Cold overnight
low temperatures continue with very low wind chills Tuesday night.

&&

.Discussion...
Low pressure area is moving south through the region this evening.
Some light showers have been reported but no significant totals
are expected. Plenty of cold air will be advecting into the region
over the next day. Along with the cold air there will be windy
conditions. Winds will be increasing through the morning hours
peaking anywhere from the late morning through the afternoon
hours. The west side of the valley and coastal foothills should
see the strongest winds where isolated 50 mph plus gusts may be
possible. The winds will ease up a bit for many valley location
Tuesday evening but remain locally strong along the west side of
the valley. Winds will remain breezy on Wednesday but lighten up
Wednesday night into the Thursday. The New Year will be very cold
with many valley temperatures dipping into the mid 20s. The colder
foothill locations will likely dip into the upper teens to mid 20s
and mountain valley locations will likely dip into the single
digits for a couple of nights.

Expect a couple of really cold nights followed by slow improvement
in the overnight lows but still dipping below freezing for most
valley areas likely through the weekend. The coldest valley lows
look to occur Thursday and Friday.

.Extended Discussion (Friday through Monday)

High pressure ridging will bring a dry start to the new year. In
contrast to New Years Day, the rest of the week and into next week
will have light and variable winds. Friday and Saturday mornings
are expected to be quite cool and there could be patchy frost. A
weak system flattens the ridge somewhat Sunday to Monday, but it
won't bring much of an impact to our CWA except for some increased
upper level cloudiness. EK
