Southeast Alaska Forecast Discussion
National Weather Service Juneau AK
619 AM AKST Sat Nov 25 2017
.SYNOPSIS...SW jetstream aimed at British Columbia this morning
with a slight anticyclonic curvature. Major upper level low center
is now around 52N 148W with pretty good cold air -36C at 500 MB.
This cold air aloft actually did bring some lightning yesterday
and last night so kept isolated T-storms in our outside waters and
offshore due to the instability over warm water. The operable word
is showers with the rain-snow line north of Sitka over to south of
Juneau. The main surface low has filled to 988 MB but still
producing whole gales around the associated occluded front.
Interestingly, IR GOES satellite imagery shows what looks to be a
north-south front, but in fact is moving northwestward as a line
of cells on radar. There are other bands to watch for snow amounts
in the north, but methinks that the big amounts are over for the
most part, hence, dropped the warnings and advisories. Water temps
cold enough in Lynn Canal, Glacier Bay, and upper Yakutat Bay for
freezing spray which we forecasted "heavy" tonight for northern
Lynn Canal.
&&
.SHORT TERM...Forecasts reflect the showers today and cooler temps
in the north. Plenty of wind in the channels and outside, but the
trend will be less wind until it picks up again tonight. Gust
factor pretty high with the cells, so gusts are a factor
today.This wind will be due to a developing wave that will become
996 MB later this morning off Dixon Entrance, but should rotate
back westward into the Gulf. With moderate high pressure over the
Yukon gotta keep wind in the forecast including tonight.
Probability of precipitation (POP) trending downward through
tonight making Sunday a relatively dry day. Flying conditions
improving except for right in the showers. Used 25/00Z GFS
combined with 06Z NAM and previous forecasts. Confidence only
moderate due to the uncertainty with the shower amounts.
&&
.LONG TERM...Rather different weather pattern for the Gulf of
Alaska and SE Alaska for the long range period compared to what we
have seen over the last few weeks. Mean 500 mb trough axis is
forecast to shift westward to be more over western Alaska and the
Bering Sea opening the door for warmer and wetter SW flow through
much of next week. Several shortwaves are embedded in the SW flow
pattern and promise to bring rather unsettled conditions through
late week at least.
Several new trends are apparent in the long range forecast today.
First off, the scenario of a weak low that was forecast yesterday
to advance on Cross Sound from the SW on Tue has been abandon in
favor of a stronger low crossing over Haida Gwaii late Mon night.
This has stabilized wind forecasts for the NE gulf and gulf coast
Tue with more general SW winds expected now, but has dropped
confidence on wind forecasts for the extreme southern panhandle
Mon night (due to some indications that guidance wants to put the
low even further SE and a wide spread on low strength). Used Nam
and some ECMWF to represent it as both had a decent track and
strength.
Second forecast trend is for a general increase in winds in many
areas Tue night into Wed. Several models are now suggesting a
rather vigorous front will travel east across the gulf at that
time with 20 kt (Canadian) to 35 kt (GFS) winds accompanying it.
Ended up increasing wind in the forecast with a wide area of 25 to
30 kt winds across the gulf. Winds also increased in the inner
channels to 15 to 25 kt especially for the southern panhandle.
Final trend is the general southerly flow and warm air advection
that will affect just about the entire panhandle. Warmest
temperatures appear mid week with many areas threatening to rise
above freezing by Wed. With these warmer temps snow level will be
rising above sea level and snow will be changing to rain for many
areas.
Main changes to the forecast were from Mon night through Wed with
changes in low position and strengthening fronts changing around
the wind forecast a bit. Main guidance was Nam with some ECMWF
followed by WPC guidance for later periods.
