NWS Forecaster Discussion




Southeast Alaska forecast discussion 
National Weather Service Juneau Alaska 
354 PM akst Thursday Jan 29 2015 


Short term...some colder air remains in place and the Arctic 
front has remained as far south as the Auke Bay area for a good 
portion of the day today. Snow showers at the back of the 
Mendenhall Valley totaled more than 1/2 inch before finally 
warming up above freezing. Farther north, heavy snow continued to 
fall at the Kensington mine into the afternoon. The frontal 
feature that resulted in heavy snow in Haines and Skagway 
overnight is weakening as it continues to slowly move north. 
Scattered rain and snow showers will continue through the evening 
and then diminish to an end overnight for the northern zones with 
scattered shower activity in the Yakutat area continuing through 
the night. More southerly locations have been dry for the most part 
since late morning. 


There have been some breaks in the cloud cover today...primarily over 
the southern Panhandle...and more breaks will show up farther 
north. Enough so that fog has been included in some of the 
Panhandle taf sites. Whatever fog does form should disperse 
quickly tomorrow with the first light winds of the day. 


Winds and seas not much of a factor through tonight. A long period 
(8 to 10 seconds) 8 foot swell dominates most of the outer coast, 
but very little in the way of wind wave. An offshore gradient will 
intensify tomorrow over the far northern Inner Channels. Look for 
northerly gales to 40 kts over northern Lynn Canal by tomorrow 
afternoon with 30 knots small craft winds over southern Lynn and 25 
knots small craft winds over Glacier Bay. Very strong winds will be 
blowing out of Taku Inlet as well, and suspect things will be 
getting pretty gusty near downtown Juneau by the end of the day 
tomorrow as well. 


Preferred a blend of the NAM with a little help from Gem for 
pressure and wind. Pop and quantitative precipitation forecast from European model (ecmwf) and GFS. No change to 
temperatures. Overall confidence is average. 


Long term...upper ridge will build NE into interior Alaska and become 
a blocky upper high by Friday night. This will build surface high over 
interior Alaska and northwest Canada through Sat. This high will eventually shift 
to the east then southeast through western Canada next week as upper high shifts southeast 
and merges with ridge to the east of the area. Weakening occluded 
front will move northward and affect mainly the southern area Sat-sun. Looks 
like stronger systems will try to move in next week...but model 
agreement decreases so confidence in timing and track are fairly low. 
Used blend of the 12z European model (ecmwf)/Gem/NAM Friday night-Sat night...then 
ec/Gem blend for sun...then wpc for Monday Onward. Blended wpc with 
the ec/Gem blend Sun night to smooth the transition. 


Colder air will filter into the northern area Friday night and Sat...and 
reach the Central Area Sat night. Winds will increase to storm 
force in Lynn Canal with gales over much of the remaining northern 
channels Friday night and Sat. Will have strong outflow winds 
develop...and there is potential for mountain wave activity in the 
downtown Juneau area Friday night-sun. Occluded front moving northward will 
likely spread some precipitation into the southern area for Sat night and 
sun...but will shear apart as it tries to get further north due to the 
strong blocky high. 


Will see moderating trend in temperatures by midweek. As mentioned 
before...one or more systems will likely move into the area but 
have low confidence in track/timing. Will have gradually 
increasing probability of precipitation for Tue-Thu. Looks like by time any significant 
precipitation would get in...it will warm enough for the precipitation to be 
mostly rain...especially by Wednesday night-Thu.
