Southeast Alaska Forecast Discussion
National Weather Service Juneau AK
217 PM AKST Mon Dec 21 2020

.SHORT TERM.../Monday night through Wednesday night/...Monday has
been a relatively calm day with light winds and mostly cloudy
skies in most areas with some isolated light convective showers
and isolated fog around the Panhandle.

This short-lived lull will quickly come to an end as a potent
storm-force frontal system moves toward southeast Alaska for the
Tuesday night through Wednesday night timeframe, bringing with it
heavy rain for the majority of the Panhandle and appreciable snow
amounts for the Haines and Klondike Highway areas. Model guidance
continues to show that there will be a deep layer of moisture
across the Panhandle with a deep layer of cold air for areas west
of Haines and north of Skagway, as well.

A Winter Storm Watch is in effect for inland areas on the
Klondike highway north of Skagway and the Haines Highway west of
Haines for 7 to 14 inches of snow from Tuesday afternoon through
Wednesday morning. This system is carrying with it a long fetch of
deep moisture originating from the central Pacific "Pineapple
Express" region aimed toward southeast Alaska. As forecast
soundings show, a deep layer of cold air, extending all the way to
the surface, will be in place for these areas to receive
significant and impactful snow amounts. Use extra caution and take
extra time if you must travel these highways Tuesday afternoon
through Wednesday morning. Prepare for limited visibility and
slippery roads.

For the rest of southeast Alaska, the primary form of
precipitation should remain rain as warm air advection as can be
seen at 850 mb in the models will be pushing into the central and
southern Panhandle ahead of the front, keeping temperatures
fairly steady in the middle 30s to lower 40s on average for most
places. As for the models, they are in pretty good agreement about
this scenario for the short- term forecast period. This is
another atmospheric river scenario for southeast Alaska with model
forecast Vertically Integrated Water Vapor Transport(IVT) values
of 700 to 800 kg/(ms) as the frontal system approaches the
Panhandle. Rainfall amounts of 1 to 2 inches can be expected
across the Panhandle with higher amounts possible in areas that
favor upsloping. Flooding is a concern.

The outside waters, inner channels, and the Panhandle will see
strong winds due to a tight pressure gradient between a strong
high in British Columbia and the approaching frontal system.
Mariners should exercise extra caution Tuesday into Wednesday if
they must venture out due to the high winds and waves. Operators
of more susceptible high profile vehicles should use extra
caution while driving in the gusty winds. These winds could blow
down trees and power lines. A High Wind Watch is in effect from
Tuesday evening into Wednesday morning for the Juneau/Douglas area
and Gulf coastal areas in the central and northern Panhandle
including Port alexander, Sitka, Elfin Cove, Pelican, and Yakutat.
As the front moves inland over the Panhandle, the associated low
will move inland over south-central Alaska and weaken.

Fog remains a possibility over some areas in the central and
southern Panhandle Monday evening into Tuesday morning due to
decreased cloudiness and calmer winds preventing convective mixing
and allowing for good radiational cooling to occur.

.LONG TERM.../ Wednesday to Monday as of 9 pm Sunday / Major
frontal feature finishes moving through Southeast Alaska
Wednesday, with a small feature running northward on the front as
it moves through the panhandle. A large broad area of low
pressure will slowly weaken over the Bering Sea. The good model
agreement in regards to the big front comes to a halt on
Wednesday. Thursday to into the weekend, the pattern over the
gulf looks much more confused a broad area of lower pressure that
is expected to persist. The various operational solutions have
difference in features, strengths, and locations moving through
the gulf during the weekend.

The Misty Fjords region will continue to keep snow falling as a
low level offshore cooler flow reinforcing the surface
temperatures. Will continue to watch the potential snow event for
the mid week.

There is one bit of minor agreement in the chaos for the last part
of the week, and that occurs Friday morning with a more developed
low moving northward just offshore of Haida Gwaii and the
panhandle. If that stays in the forecast, there could be a
significant system Christmas morning over the southern panhandle.
At the present, have there is a weaker version from WPC than the
operational solutions, that we can fine tune with future model
runs. Overall, think there will be moderate confidence on the
weather system for Friday, with lower than average confidence for
the weekend and start of the weekend.
