NWS Forecaster Discussion




Southeast Alaska forecast discussion 
National Weather Service Juneau Alaska 
430 am akdt Wednesday Oct 1 2014 


Short term...clipper low that tracked from the northeast Gulf 
southward Tuesday through Tuesday night has weakened to an open 
wave trough that is moving over the southern Panhandle and into 
British Columbia. Scattered to isolated showers over the southern 
regions will end early this morning and as high pressure that is 
building over the Yukon moves southward skies will begin to 
clear. This area of high pressure will cover the Panhandle through 
late tonight with clear skies continuing. The upper level trough 
that dropped over the region last night brought in cold air mass 
that will remain in place through the night. Expect day time temperatures 
to rise into the upper 40s to low 50s but some uncertainty on 
this. There is the case that the cold air mass will keep temperatures low 
but insolation due to the clear skies may provide more warming. Not 
as much of an issue for overnight lows as the cold air mass along 
with radiational cooling will drop temperatures into the middle 20s to low 
30s for the northern areas and middle to upper 30s for the south. 
Patchy fog has developed for the central Panhandle as skies began to 
clear this morning. Fog will burn off this morning as temperatures 
rise. With the lingering moisture development of black ice is 
possible tonight but drying trend through the day should limit 
this over the northern areas. 


Gradient between the high currently over the Yukon and the exiting 
low producing small craft winds over the northern Lynn Canal. The 
gradient will weaken today with decreasing winds this afternoon, 
but then reform tonight from the next advancing system. A 
developing low will move from the North Pacific into the western 
Alaska Gulf tonight. Winds over the offshore waters will rise to gale 
force for the southwestern areas by late tonight. As this low 
advances the pressure gradient between the Canadian high will begin 
to increase easterly outflow winds. Main impact from this system 
will not be felt until Thursday. With the clear skies tonight and 
lingering moisture from today there is possibility of fog 
developing over the southern areas but think the increasing winds 
will limit this. 


Models were in good consensus for the synoptic pattern. 
Differences will mainly with day time temperatures and fog development 
late tonight. Preferred a blend of NAM/European model (ecmwf) which was still 
in line with inherited forecast, so few changes were made to the 
grids. Forecast confidence is above average. 


Long term...models remain in general agreement for a gale force 
low entering south central Gulf early Thursday morning with 
increasing clouds and probability of precipitation over the outer waters...then leading to 
a potential heavy rainfall during the afternoon into the evening 
hours across the southern and central Panhandle along with strong 
winds developing over the immediate coastal sections Thursday 
afternoon into the evening hours. Posted strong winds headlines 
for zones 23 and 27. The low will track northward to the 
northeastern Gulf Coast through Friday night. Used the NAM and 
European model (ecmwf) for a few fine tunes over the pressure...winds...pops and 
quantitative precipitation forecast fields through Saturday night as the low continues to weaken 
over the northern Gulf. High pressure area across the northwestern 
Canada will drift east as the low tracks northward across the 
Gulf...thus the northerly pressure gradient across the Inner 
Channels will diminish and the frontal boundary associated with 
the low will produce general southerly winds by Friday. 


Model spreads become larger Sunday into early next week with an 
upper level shortwave trough persisting across the Gulf. Merely no 
changes were made for the extended forecast periods and added day 
8 with the GFS based guidance. Maintained generally wet weather 
through early next week with decreasing probability of precipitation by the middle week. 
Forecast confidence remains above average with the frontal passage 
through late Friday then falls below average through the weekend 
into early next week.
