...VERY SNOWY AND COLD START TO DECEMBER...

A cold air outbreak that began at the very end of November continued
into December. The coldest air penetrated from Canada at the start
of the second week when temperatures in the Mendenhall Valley fell
below zero for the first time since March of 2014. Elsewhere, the
very cold temperatures resulted in wind chill advisories along both
highways and freezing spray over portions of the inner channels.
Temperatures rebounded in the third week of the month to near normal
or even above normal values. There was a slight cool down leading up
to Christmas, but temperatures once again returned to near normal or
slightly above normal for the last week of the month.

Total accumulated precipitation for the month ranged from below
normal for the northern and southern ends of the panhandle, to above
normal for the central outer coast and central inner channels. Most
of the precipitation that fell during the month occurred in the
first half of the first week, and again during the third week of the
month. The first two weeks of the month featured a major snow event
that produced up to 32 inches of snow over a 48 hour period. In
spite of the lower than normal total precipitation in the Yakutat
area, snowfall totaling more than 10 inches in the first week of
the month kept the monthly snowfall very close to a normal value.
Precipitation toward the end of the month fell both as rain and snow
in many locations, owing to the warmer than normal temperatures that
occurred late in the month.
