Southeast Alaska Forecast Discussion
National Weather Service Juneau AK
433 PM AKST Tue Nov 16 2021
.SHORT TERM.../Through Wednesday night/ Active weather continues
across Southeast Alaska. A front associated with a gale force low
brings widespread precipitation across the panhandle this
afternoon. With this front, temperatures have warmed at the
surface leaving only the far northern panhandle below freezing.
These areas include Yakutat, Skagway, and Haines. Where others are
seeing rain, these locations are observing widespread snowfall,
even heavy at times. Winter Storm Warnings are ongoing through
Wednesday morning. So far, Yakutat reports 6 inches, Haines 7
inches, and Skagway to be confirmed. A Winter Weather Advisory is
in effect for Hyder through Wednesday morning as well.
As the storm moves through the panhandle this afternoon, winds
will increase as pressure gradients tighten. Small Crafts to Gales
are expected through the inner channels this evening with a
decreasing trend through late tonight. Over land, gusty
conditions are also being observed. Strong wind headlines have
been posted for west POW, Sitka, and Juneau areas for gusts to 40
mph.
With gusty conditions, a warmup occurs through tonight. Most of
the Panhandle can expect rainy and windy conditions with
temperatures in the mid 30s to lower 40s. The warmup though is
short-lived as third front marches eastward across the gulf
Wednesday and into the panhandle Wednesday night. First showers
over Yakutat. Then Wednesday night, colder air filters into the
Inner Channels with showers rapidly turning to snow. This includes
areas deep into the south central Panhandle.
.LONG TERM.../Thursday through Sunday/ Very active period
continues through the week and into the weekend as winter takes
hold of Southeast Alaska. Continued chances for accumulating snow
and Much Colder temperatures are in the forecast.
**Heavy Snow Showers Thursday and Much Colder Temperatures**
The period begins with a deep trough over Southern Alaska with a
strong jet streak rounding the base over the gulf. The jet streak
pushes right into the Panhandle placing the northern half of the
region in an area of enhanced lift under the left exit region. At
the same time, very cold arctic air will be ushered into the
region with 850mb temps falling to around -11C to -15C! With a
surface low remaining in the northern gulf through Friday, this is
a great set up for heavy snow showers across much of Southeast
Alaska. The challenge is determining which areas will receive the
greatest accumulations given the nature of showers. Confidence is
highest for potentially impactful accumulations around Yakutat,
Pelican, and Juneau. Due to this, A Winter Storm Watch has been
posted for Yakutat and Winter Weather Advisories have been posted
for Thursday for Pelican and Juneau areas. Accumulations are
expected to greatly vary over short distances; however upslope
favored areas are expected to receive the heaviest snow. The rest
of the Panhandle should experience snow showers, with rain mixing
in at times across the south.
**Potential Southern Panhandle Winter Storm Friday**
Another potentially impactful system moves into the region on
Friday as a weak area of low pressure traverses the gulf and
pushes into the far Southern Panhandle. At the same time, the
aforementioned low in the northern gulf weakens and dissipates as
a strong arctic high pushes south into the region. This sets the
stage for a period of snow across the Southern Panhandle on
Friday. The main challenges with this system will be how much
snow is possible at sea level and if the arctic high to the north
will be strong enough to dry out the atmosphere and limit
accumulations. Current forecast is for minor accumulations across
the Southern Panhandle Friday morning before a transition to rain.
Areas that could remain all snow are northern Prince of Wales
Island, and along and north of Sumner Strait. There are still
model discrepancies regarding the low track and QPF, so confidence
remains low in the Friday forecast. This will be watched closely
over the next few days as the potential is there for accumulating
snow at sea level.
**Saturday Drying Trend and Sunday Potential Winter Storm**
As the aforementioned arctic high drops south into the region,
expect a drying and clearing trend from north to south Friday
into Friday night. Some of the coldest temperatures of the season
are possible Saturday morning as lows could drop into the single
digits across the north! Highs may not make it out of the 20s for
many areas Saturday afternoon. With such cold air in place, the
next system expected to move in Sunday into Monday could bring
another round of accumulating snow before a change to rain. Still
a little too early to tell exact details; however this system will
be monitored closely over the next few days.
Forecast confidence is above average for the long-term forecast
period as the models were generally in good agreement. A
GFS/CMC/ECMWF model blend was used to create the forecast.
