...Below normal temperatures and well below normal precipitation for
November 2017...

November started out  decidedly colder than October and generally
below normal across all of Southeast Alaska. Departures from normal
ranged from less than a degree to more than 6 degrees below normal
with the coldest values over the norhtern Panhandle. This was
largely due to an extended outflow event. High pressure set up over
western Canada early in the month and, with the routine presence of
lows in the gulf, strong norhterly or northeasterly winds dominated
the wind regime over the northern two thirds of the panhandle for
much of the month.

With cold surface air in place earlier than normal, November snow
totals were generally above normal and, in some cases, more than a
foot above normal. In spite of the excellent start to the snow
season, most locations reported lower than normal monthly
precipitation with at least 11 climate sites that are routinely
monitored with regular daily data reporting record low precipitation
totals for the month.
