NWS Forecaster Discussion




Southeast Alaska forecast discussion 
National Weather Service Juneau Alaska 
230 PM akdt Monday Sep 1 2014 


Short term...an upper level trough is passing over the Panhandle 
from northwest to southeast. At the surface, weak low pressure off 
the central outer coast with a trough extending west-northwest will move east 
into Canada overnight. Shower activity is still present over 
Southeast Alaska, but is diminishing from west to east. Cold air 
aloft will maintain the threat of isolated marine thunderstorms 
tonight over southern coastal waters as well as the Dixon Entrance. 
Have also included them over the southwestern outer coast, where 
the threat is the greatest. As showers depart to the east, partial 
clearing is expected tonight and tomorrow over portions of the 
Panhandle. Large breaks in the cloud cover have already formed 
over western portions of the Yakutat zone as of early this 
afternoon. With the decreasing cloud cover, overnight temperatures will 
dip a few degrees lower than in the past few nights with some 
locations getting down into the upper 30s. Similarly, tomorrow's 
high should be a bit warmer than in recent days where partly 
cloudy skies last into the afternoon. With breaks in the clouds 
tonight, potential for fog is enhanced and have included this in 
both marine and public zone forecasts. Conditions should improve 
quicker than what was observed today, where many locations saw 
ceilings remain well below 1000 feet for most of the day. Looks 
like it will be a mostly dry and partly sunny day...just in time 
to go back to work. 


Used a blend of NAM and European model (ecmwf) for updates to pressure and wind. 
Pop and quantitative precipitation forecast from Gem and European model (ecmwf). Temperatures per bias corrected NAM and 
European model (ecmwf). Forecast confidence is average. 


Long term...models remain in general agreement through Thursday 
evening with an upper level shortwave trough over British Columbia 
coast Tuesday night moving east away from the area and an anchored 
large upper level low over the southern Beaufort Sea starts 
drifting east to Banks Island through Thursday night. A weak upper 
level ridge will continue to dominate across the Gulf of Alaska 
with near zonal upper flow over Southeast Alaska. A weak surface 
low pressure system over Prince William Sound Tuesday night will 
dissipate by late Wednesday morning as a surface high across the 
western Alaska interior expends east and a ridge of high pressure 
continues to build over the eastern Gulf to the Panhandle. Blended 
the inherited forecast package with the NAM and GFS for their good 
consensus and initialization through Thursday evening. 


At the lower level...a developing low south of Alaska Peninsula 
has a sub-tropical moisture connection and will drift north to 
Bristol Bay through Thursday night...pushing a frontal passage 
east over the Gulf in between the high pressure over western 
interior drifting east into the the Yukon and the ridge of high 
pressure across the Gulf moving east over the Panhandle. The ridge 
across the Panhandle Wednesday night will erode southeastward by 
Thursday night...opening a door for frontal rain bands coming into 
the outer waters and the central Panhandle Wednesday night...then 
move to the southern areas by Thursday before dissipating late 
Thursday evening. With prevailing near zonal upper flow...expect 
no significant upper dynamics supporting the surface progress but 
the sub-tropical origin of the incoming moisture may pose certain 
moderate rainfall over the central and southern Panhandle coastal 
regions. 


Pressure gradient over Southeast Alaska will remain somewhat 
relaxed between the main highs and lows in distance...and expect no 
significant wind speeds but small craft level seas over the 
central outer waters Wednesday night due to westerly swells. 
Continued onshore low to middle level flow will keep Southeast Alaska 
under mostly cloudy to cloudy skies with overnight lows in the middle 
to upper 40s across the northern and central Panhandle to the 
lower 50s over the southern areas...and daytime highs mostly in 
the middle to upper 50s over the northern areas to the lower 60s 
across the southern Panhandle. 


From Friday Onward...model diverting becomes larger as the GFS 
stays on a fast progressive Mode with the Bristol Bay low drifting 
northeast across the southern interior and Yukon toward the 
weekend...while the European model (ecmwf) shows a significant slower Mode to bring 
the low over the northern Gulf by Saturday morning. As a 
result...the GFS builds a ridge of high pressure quickly across 
the Gulf over the weekend while the European model (ecmwf) keeps the influence of 
low pressure across the Gulf. Opted the new wpc ensemble solutions 
for the remaining long term periods. Forecast confidence is about 
average through late Thursday then falls below average for the rest 
of long term periods. 


&& 


Aviation...marginal visual meteorological conditions conditions will prevail for most of the 
night with some lingering pockets of low imc. Potential for 
widespread fog late tonight may be a factor for early morning 
aviation operations. Weak pressure gradient at the surface and 
aloft should prevent any significant turbulence through tomorrow 
afternoon. 


&& 


Ajk watches/warnings/advisories... 
public...none. 
Marine...Small Craft Advisory for pkz012. 
Small Craft Advisory due to seas for pkz041>043.
