SUMMARY:

The first half of December was consistently cold with two significant winter storms within a week
(8th-9th, 15th) producing most of the month's precipitation and snowfall.  Snow was above average,
while precipitation was slightly below.  Meanwhile, a Pacific airmass moderated temperatures around
the holidays and nearly (but didn't quite) offset the below normal trend of the first 3 weeks.
