southeast alaska forecast discussion
national weather service juneau ak
314 pm akdt Mon oct 14 2019

Short term through Wednesday night ... A strong front
interacting with the southern panhandle is bringing wind and rain
to parts of the panhandle, and will lift into the central northern
pandhandle by Tuesday. Satellite imagery continues to show a
broad area of low pressure encompassing the entirety of the gulf
of alaska. An occluded front extends from the low across the s
gulf attached to a warm front lifting into the S panhandle and a
n-s oriented cold front along 140w. A deep upper level trough over
the W gulf will move eastward across the southern gulf Monday.

Multiple waves rotating around the low will make for a complex
system that will impact the area through at least Wednesday.

Forecasting becomes challenging beyond Wednesday due to
substantial model disagreement, and will need to keep an eye on
when or if models come into relative agreement on additional
impacts.

The first wave has lifted into the SE panhandle, and a widespread
area of strong gale force winds is situated across the outside
waters across the central gulf, into the dixon entrance and
southern clarence strait, with small craft winds through many of
the inner channels. A strong east- west gradient will continue to
bring storm force winds this afternoon from dixon entrance to
cape edgecumbe. The front will continue to lift N overnight and
into the N gulf by Tuesday morning, bringing rain with it. Some
diffluence aloft and frontogenesis over the area will contribute
to precip totals. Later tonight precipitation will reach the far
northern inner channels where temperatures may be cold enough for
snow, or at least a mix of rain and snow. Strong southerly flow at
700 mb will drive some moisture over a colder airmass in the
lower levels. Surface temperatures near haines and skagway will
likely be in the mid- 30s, but don't expect any snow to accumulate
near sea level. Along the klondike and haines highways could see
upwards of 1 to 3 inches of snow into Tuesday morning.

At the surface the broad area of low pressure will continue to
churn across the entire gulf with smaller embedded lows orbiting
around the central area of low pressure. Another wave will push up
from the S and impact the area late Tuesday afternoon into
Wednesday. Not currently expecting this impulse to be as powerful
as what the area is currently dealing with, and winds offshore
will likely be much weaker than Monday's front, maxing out around
25 kts to 30 kts Tuesday afternoon in the SE gulf and up clarence
strait. Rain will likely continue through Tuesday night. 2-day
precipitation totals will likely range from 1 to 3 inches across
the southern and central panhandle, with some southern areas
possibly reaching up to 4" of rainfall.

Gusty winds are also anticipated with the first front this
afternoon into tonight. Widespread gusts to 40 or 45 mph are
likely for the southern panhandle and southern outer coast. High
winds are not likely due to many areas being blocked to the east-
west gradient and very stable airmass aloft, but do expect strong
winds for juneau. Main changes made to forecast were adjustments
to winds directions through the forecast period. Overall forecast
confidence average.

Long term Wednesday through Monday as of 10 pm Sunday
little change made to the longer term forecast as there remains a
lot of uncertainty. System from short term period will be lifting
out wed, but there remain model differences on where some of the
smaller scale features will go. Upper flow will be flattening
during the thu-fri time frame, with multiple shortwaves expected
to move E across the southern gulf. Some amplification is
possible over the weekend, but models disagree on interactions
with northern and southern stream shortwaves that would affect how
amplified things get. The overall pattern will tend to keep
things on the wetter side, albeit with some breaks likely in the
precip between systems. Looks like temps will remain fairly close
to normal for this time of year as well.
