Southeast Alaska Forecast Discussion
National Weather Service Juneau AK
Issued by National Weather Service Fairbanks AK
325 PM AKDT Wed Oct 6 2021

.SHORT TERM...Today through Saturday...

The current partly cloudy conditions across the Inner Channels
and isolated showers along the Outer Coast will give way to
widespread rain across Southeast Alaska tonight and Thu. A weather
front approaching from the west tonight will move over the
Panhandle Thu and move inland early Fri. This will bring rain
into the Yakutat area late this afternoon, spreading southeast to
Sitka and Juneau by this evening, and to the southern Panhandle by
early Thu. Rain will continue through the day Thu, then taper off
to showers Thu night and early Fri as the front moves inland.

Expect rainfall amounts by Thursday night of 1.00-1.50 inch along
the Outer Coast north of Sitka, with 0.50-1.00 inch along Lynn
Canal and south of Sitka. Snow levels currently near 2000 ft are
expected to rise above 3000 ft tonight and Thursday with the
front. Southeast winds will increase to 35 kt tonight along the
Outer Coast, and 15-25 kt along Lynn Canal with winds persisting
into early Thu. The winds should taper off late Thursday and early
Friday as the front moves inland.

A stronger occluded front is forecast to move east across the
Panhandle Friday, and move inland on Saturday. This is expected
to bring moderate to heavy rain to most of Southeast Alaska
Friday through Saturday. Expect southeast winds to increase to
brief gale force Friday PM along the Outer Coast as the front
approaches, then turn southwest 15-25 kt Fri night and Sat as the
front moves inland.

Models at 18Z all verified 3-5mb too weak on the low forming in
Norton Sound, and 3-4 mb too weak on the low south of Shemya.
The NAM had the lowest pressure on these features, and thus was
preferred the preferred model in the short term. Main difference
over Southeast Alaska is that the NAM brings the precipitation in
1-2 hrs quicker today, and the NAM has the heaviest precipitation
north of Sitka tonight through Thursday night. This was supported
by the earlier onset of rain in Gustavus and Yakutat today.

.LONG TERM...Sunday through next Tuesday.

Several systems are expected to pass over the region through the
extended forecast, bringing measurable rain with brief breaks in
between. The progressive upper level pattern of ridge/trough/ridge
moving through the westerly jet will keep each surface low/front
moving through the area from west to east.

From Saturday night through Sunday noon, a vertically stacked low
will track from the Northern Panhandle southeast to to the
Southern Panhandle. Heavy rain along the coast just ahead of the
low will move from the Yakutat area Saturday night south to the
southern Panhandle by Sunday morning. Winds will shift to N-NE
behind this low on Sunday with showers tapering off from the north.
Expectation of breaks in the clouds and colder air aloft Sunday
night/Monday morning will make that the coldest day of the long-
range.

Most of Monday is looking like a break. Then the 3rd system of
the extended forecast moves into the region from the west by early
Tuesday morning. Models differ some on location of the Tuesday low
(day 7/8) as it moves across the gulf, but still have relatively
similar timing. They are showing the potential for storm force
winds over the gulf late Monday night into Tuesday. This will be
one to watch over the coming days.
