NWS Forecaster Discussion




Southeast Alaska forecast discussion 
National Weather Service Juneau Alaska 
619 am akst Wednesday Nov 26 2014 


Synopsis...an upper level ridge of high pressure over the western 
Gulf will continue send cold Continental air over the Yukon and Southeast 
Alaska through Wednesday night. A surface high pressure will continue 
to strengthen over the Yukon and increase the pressure gradient 
along the Coast Mountains from the northern Gulf to Misty Fjords. 
A inverted trough from a low south of haida gwaii will be over the 
the Inner Channels that will increase the northerly winds over the 
forecast area during the short term period. 


&& 


Short term...the low clouds that are over the Panhandle this 
morning will slowly thin through morning with increasing dry 
colder air moving over the area. The patchy fog will also 
dissipate through the morning hours. Most of the forecast area 
will be mostly clear by late this afternoon with the increasing 
offshore flow and persist through tonight. High temperatures will 
range from the lower 30s in the far northern areas to the lower 
40s over the southern areas. Tonight lows will be on the colder 
side than it has been with clear skies and cold air advection from 
the north. Overnight low lows will range from teens over the 
northern half to the lower 30s over the southern half. Areas where 
the wind is blowing it will be warmer and colder in wind sheltered 
areas. 


Wind wise...the winds will increase the day from the north- 
northeast from the tightening pressure gradient and the increasing 
cross barrier flow from the east. The high wind watch for the 
downtown Juneau and Douglas area has been upgraded to a High Wind 
Warning from late Wednesday night into Thursday. This is for the 
development of taku winds with winds starting to gust to 40 miles per hour in 
the late afternoon and continue to increase through the night to 
be around 60 miles per hour. Other locations along the Coast Range will see 
locally windy conditions with high gusts in exposed areas. The 
strong northerly winds will also develop strong winds gusts of 45 
miles per hour near the Skagway,Haines and near interior pass of Misty Fjords 
this afternoon and persist through tonight. The cold temperatures and 
strong winds will generate cold winds chills of 22 below zero 
along The Klondike Highway. 




&& 


Marine...winds and strong outflow winds will increase through 
today and tonight from the northeast as the pressure gradient 
strengthens. Gales to small craft winds will develop over the 
northern Inner Channels along with areas over the northeast Gulf. 
These winds will spread southward through Wednesday night as the 
inverted trough moves north through the Panhandle. This will 
increase the winds over northern Lynn to storm force and spread 
gales southward through the entire Inner Channels. Gusts to 45 knots 
will develop from interior passes along the Coast Mountains and 
near the northeast Gulf and in Yakutat Bay by Wednesday afternoon. 
These outflow winds gusts will increase to 65 knots through 
Wednesday night. A large swell from 10 to 14 feet will develop through 
Wednesday night down Lynn Canal into northern Chatham from fully 
developed seas produced from the storm and gale force winds. 


&& 


Long term...dry weather and clear skies will continue through the 
week with strong outflow winds. Area of high pressure over British 
Columbia will begin to drift to the south through Saturday while 
high pressure over the western Pacific tracks towards the eastern 
Pacific. The inverted trough that developed over the Panhandle 
will move southward as well through Saturday. As the outflow winds 
move in cold polar air mass from western Canada temperatures will drop 
into the low teens overnight and low to middle 20s during the day. 
Clear skies and radiational cooling will aid in dropping the 
overnight lows possibly to the single digits. Locations with the 
stronger outflow, gap flow and gradient winds will see warmer 
temperatures due to downsloping. Indications that a short wave will form 
in the northern Alaska Gulf Saturday evening along a frontal boundary 
extending from a closed low in the Chukchi Sea. The wave will move 
towards the Panhandle with precipitation developing from west to 
east Sunday into Sunday night. Still some uncertainty with the 
track and strength of this system but with a deep cold air mass 
developing over the Panhandle through the week there is potential 
of an over running snow event which would produce the first 
measurable snow of the season. Behind this first wave late Monday 
into Tuesday should be a stronger system and frontal boundary 
associated with a low in the Bering Sea. Indications this system 
would have higher quantitative precipitation forecast amounts but it moves in a warmer air mass 
and this precipitation may be mainly rain. 


The strong winds are a result of tight pressure gradient between 
the Canadian high and the Panhandle inverted trough. Strongest 
gradient looks to occur around 15z Thursday then weakens as the 
Canadian high and Panhandle inverted trough shift to the south. 
For the downtown Juneau and Douglas area he taku winds that begin 
to develop late Wednesday night will continue into Thursday 
night. Latest mountain wave model runs had stronger cross barrier 
flow at 850 mb but were not showing the typical 500 mb critical 
level, but are indications of induced critical level. In addition 
to the easterly outflow and gap winds, a north-south pressure 
gradient will produced gale to storm force winds over the north-S 
orientated Inner Channels with strongest over the northern 
portions. With the long fetch of sustained strong winds from north 
Lynn Canal down to North Chatham Strait expect higher seas to develop. 


While the newer model runs did indicate higher cross barrier flow 
there were not many changes from previous model runs and 
forecast. Changes for the week were minor. The model spread 
increased with these next series of short waves for the weekend, 
and did not have enough confidence in any particular model run to 
make large changes. GFS seemed to keep the region drier while the 
European model (ecmwf) push in more precipitation by late Saturday. Forecast confidence 
is bit above average for the week then drops below average by the 
weekend and into next week.
