...A WARMER AND WETTER THAN NORMAL NOVEMBER FOR SOUTHEAST ALASKA...
A weather pattern heavily influenced by the strong El Nino brought
much wetter and warmer weather to Southeast Alaska for the month of
November. Multiple strong Gale and Storm-Force frontal systems
affected Southeast Alaska with strong southerly flow, warm air
advection, and plenty of precipitation. Around mid-month, cold,
northerly outflow from a strong area of high pressure located over
the Yukon established cold temperatures in the lower and mid levels
of the atmosphere. This atmospheric setup preceeded a strong frontal
system approaching from the south, resulting in a classic
overrunning scenario. On the 20th, A storm force frontal system
moved into the Panhandle, bringing high winds and blizzard
conditions to the Downtown Juneau and Douglas area. Much of the
remainder of the Panhandle received heavy snowfall that day before
post frontal warm air displaced the much colder near surface
airmass. As is usually the case in Southeast Alaska, post frontal
precipitation transitioned from snow to rain from south to north.
The southern third of the Panhandle received heavy rain and high
winds from that storm. Prince of Wales Island encountered a series
of minor landslides on the 20th. Late that same night, the city of
Wrangell experienced a tragic and devastating landslide due to the
heavy rain and strong winds associated with that storm.
While much of the month recorded above normal temperatures, daily
averages in the middle of the month and then again at the end were
much more seasonable. On Wednesday, November 8th, both the Juneau
and Yakutat Airports set new daily high temperature records. Juneau
recorded 50, which broke their old record of 49 set in 2016, and
Yakutat recorded 55, which broke their old record of 52 set back in
1930.
