NWS Forecaster Discussion




Southeast Alaska forecast discussion 
National Weather Service Juneau Alaska 
220 PM akdt Thursday Apr 17 2014 


Short term...early afternoon satellite imagery shows a mature 
yet compact low pressure system just off the coast of Prince of 
Wales Island just south of Cape Decision. This low will continue 
to push north and hug along the coast, and weaken. By Friday, 
this area of low pressure will become an open trough. A ridge of 
high pressure will build across the Panhandle from the south on 
Friday. 


A rather mild Thursday, as high temperatures in the area rise to 
the upper 40s to the low 50s. Southern areas are a bit cooler due 
to rain showers in the area. Dry conditions continue for the 
northern Panhandle , as northeasterly flow kept the precipitation 
from moving into the area. 


As the low tracks north, it tightens the northerly pressure 
gradient across northern Panhandle. Northerly wind of 10 to 
15 miles per hour can be found in Skagway, Haines, Gustavus, and Lynn Canal 
this afternoon. The weather front is situated along central 
Panhandle, and will continue to push north this evening. Once the 
weather front pushes through, winds will become southerly. With a 
ridge of high pressure building in behind from the south, that 
will generate a strong push of southerly wind across the 
Panhandle. Do expect the stronger southerly winds to impact 
southern Panhandle through this evening. The area of stronger 
south winds will move north through tonight into Friday. 


Forecast confidence is above average. Most numerical weather 
models are showing consensus on the weakening low tonight and a 
building ridge on Friday. Utilize a superblend of models to 
update the inherited forecast package. 


&& 


Long term...models are in general agreement through late Sunday 
for a weak upper level and surface ridge building across the 
eastern Gulf and Southeast Alaska from the south. The ridge will 
move northeastward away from the area as a low moves into the 
southeastern Gulf by Saturday morning. The low will continue to 
rotate over the Gulf through the weekend. Refreshed the inherited 
forecast package with the European model (ecmwf) through Sunday evening for its good 
consistency. For early next week...the upper low and associated 
surface feature across the Alaska Gulf will begin weakening and 
drifting southeastward. Then a ridge will rebuild over the Gulf 
through the middle week. Model divergence becomes more significant 
between the eroding ridge and a developing low over the western 
Alaska Peninsula. Blended next week forecast package with the wpc 
solutions of the operational European model (ecmwf) through Wednesday and mixed 
with a little European model (ecmwf) ensemble for Thursday. 


As the ridge builds from the south...southerly winds will 
continue to increase Friday night then by early Saturday 
morning gale force winds will begin affecting the southern 
offshore...outside waters and the southern Inner Channels as a low 
moves into the southern Gulf. Strong winds headline may need for 
Prince of Wales islands. Very rough seas of 20 to 25 feet are also 
expected over the southern outer waters. As the low continues 
progressing...pressure gradient will shift for a gradual increase 
of northerly winds across the Panhandle late Friday night into 
Saturday...then continue through early next week. For the 
remaining long term forecast periods...expect a brief ridge builds 
across the Panhandle on Monday ahead of the next developing system 
across the far western Gulf. As the system slowly drifts 
eastward...several poorly organized weak lows will move into the 
eastern Gulf through the week. Relatively higher probability of precipitation will likely 
to focus over the southern Panhandle Wednesday and Thursday.
