National Weather Service Juneau AK
535 AM AKST Fri Dec 17 2021
.SHORT TERM.../Friday and Friday night/ A weather front is
bringing snow to many parts of the panhandle this morning.
Currently snow has been observed from Petersburg and Klawock and
points west and north. Lowest visibility and ceilings have been
seen at Skagway and Haines overnight with webcams indicating that
around 1 to 2 inches of accumulation was seen at Skagway.
For Friday and Friday night, snow will be the rule of the day for
most places. Initially it will be focused on the northern
panhandle but with increasing easterly flow across the north the
precip will shift to the southern panhandle by afternoon. Highest
snow accumulations are expected along the outer coast and southern
panhandle where winter weather advisories remain up for 3 to 6
inches of new snow though other areas will likely see around 1 to
3 inches of new snow regardless. The main exception to the snow
rule will be Sitka (currently sitting at 37 degrees), and the
extreme southern parts of the panhandle where temps should get
just warm enough for some rain to start mixing in with the snow.
This will cause snow accumulations to vary widely with some areas
staying snow and getting a few inches while others see more rain
mixing in with snow totals drastically reduced as a result.
Winds will be the other factor. Some northerly winds are still
blowing in the northern panhandle this morning though much reduced
compared to yesterday. These winds will remain low through Friday,
but will start to increase again tonight as the Yukon low starts
to rebuild. The other source of wind comes from the incoming
system. SE to E winds will be dominate across the southern
panhandle Today into Tonight. Wind gusts could reach 35 or 40 mph
this afternoon near Hydaburg and other parts of southern Prince of
Wales Island. Marine winds will mostly be around 20 to 25 kt but
an area of min gales is likely just offshore of Baranof Island
this afternoon as the main frontal band with the system
approaches.
LONG TERM.../Saturday onward/...The mid range forecast begins
with a surface low and associated chances of precip moving south
out of the area as a 500mb high builds in. So Saturday should end
up seeing clear to mostly clear skies over the panhandle. Kept
strong winds in Lynn Canal due to tight pressure gradient between
Icy Strait corridor and Skagway.
Sunday and Monday look dry with clear to mostly skies as a 500mb
ridge will control the skies over southern and southeast Alaska.
Outflow winds will still be strong for the northern inner channel
marine waters.
Temperatures will still be below normal for Saturday through
Monday. So lows will, generally, be in the teens to 20s and highs
in the 20s to 30s. Coldest temps in the north, warmest in the
south, but still overall, below normal.
Tuesday is when the weather pattern has potential to change. That
being said, models usually bring weather pattern changes in too
soon so this change in the weather pattern could end up being
pushed back by a day. However, if the current projections play
out, a quick moving low pressure system would pass through the NE
gulf. This passing low would give the panhandle another round of
rain and snow Monday night into Tuesday.
As this low pressure moves southwards, there is good model agreement
that the outflow pattern returns, keeping the precipitation and
temperatures below normal through the end of next week and into
the Holiday weekend.
