NWS Forecaster Discussion




Southcentral and southwest Alaska forecast discussion 
National Weather Service Anchorage Alaska 
405 PM akst Thursday Jan 29 2015 


Analysis and upper levels... 


A high amplitude upper level ridge over the Bering Sea is the 
strongest feature over the forecast area. An upper level low 
still remains well south of the Alaska Peninsula with a weak 
trough extending out of it over southcentral Alaska. This 
pattern is producing fairly strong north to northeast flow 
aloft over the eastern Bering Sea and southwest Alaska with 
weaker southerly flow along the north Gulf Coast with southcentral 
Alaska under very weak flow aloft. 


At the surface the strong high persists from the central Bering 
Sea through northern Alaska. The main surface low is a complex 
system well south of the Alaska Peninsula with a front extending 
south of the Alaska Peninsula through the north Gulf Coast. A low 
has also developed along the front in the northwest Gulf of Alaska 
which is enhancing lift over the Gulf coastal regions. The pressure 
gradient north of this front remains fairly strong especially over 
the Bering Sea region. 


&& 


Model discussion... 


Model initialization was very good again across the spectrum of 
the main models. The one feature that rapidly diverges is the low 
that is west of Attu and moving northward. The speed and strength 
of this low vary quite a bit starting tonight. However this 
feature will remain far enough west that only the far western 
Bering Sea and Aleutians will be impacted by it. 


While the synoptic features of the GFS European model (ecmwf) and NAM are very 
similar the GFS and European model (ecmwf) look to be dong a better job with the 
precipitation amounts and therefore snow amounts in southcentral 
Alaska. The main issue is the NAM is much heavier with the snow 
amounts over the southcentral area. The GFS and European model (ecmwf) are more in 
line with what is in the forecasts. The reason the NAM looks to be 
too high is due to the amount of dry air in place already in 
southcentral Alaska...as well as the model just showing too much 
moisture through the atmospheric column. Therefore the lower snow 
amounts of the GFS and European model (ecmwf) were used as model guidance. 


&& 


Short term forecast southcentral Alaska (days 1 and 2)... 


A frontal zone over the northern Gulf Coast will continue to make 
slow progress northward this evening...spreading clouds and 
moisture into inland areas. Light snow will impact locations from 
the Copper River basin to the mat valley southward to Anchorage. 
The eastern Kenai Peninsula will also see light snow 
accumulations...with more scattered showers toward the western 
Kenai. Continued strong northerly outflow winds through mountain 
passes will continue tonight...with some local areas of blowing 
snow through Thompson Pass. Blustery wind chills will remain 
through all favored mountain passes. 


High pressure will begin to settle over the region during the 
afternoon hours Friday...with rapid clearing developing by Friday 
night. Outflow winds will begin to increase once again Friday 
evening as a North Pacific low tracks toward the Gulf of 
Alaska...but some local areas of patchy fog will be possible as 
high pressure aloft builds in. A return to clear and pleasant 
weather will resume region wide Saturday...with the exception of 
a few showers over Kodiak Island. 


&& 


Short term forecast southwest Alaska (days 1 and 2)... 


A persistent Bering Sea high interacting with a low south of the 
akpen will keep a moderate pressure gradient across SW Alaska. Northeast 
wind with cold and dry conditions across the region will begin to 
moderate on Sat as the Bering ridge begins to weaken. 


&& 


Short term forecast Bering Sea/Aleutians (days 1 and 2)... 


Disturbances moving around the low south of the akpen will keep 
windy conditions over the akpen and the eastern half of the 
Aleutians through Sat. Another disturbance will bring a chance of 
rain to these locations on Sat. A weather system skirting the 
western Bering at the end of the week will bring a chance of rain 
to the western Aleutians Friday night into Sat. 


&& 


Long term forecast (days 3 through 7)... 


Much of the region will continue to be dominated by a dry 
offshore flow pattern through the early part of next week with 
high pressure over the Mainland and a North Pacific low well south 
of the Alaska Peninsula near 50 degrees north latitude. This will 
continue to support gusty outflow winds along the Gulf Coast with 
a favorable pressure gradient in place and very cold air filtering 
out of the Copper River Basin. A chance of snow then returns to 
the forecast by middle to late week as models are hinting at an 
Arctic trough digging over the southwest Mainland from the Chukchi 
Sea...which would also result in a return of much colder temperatures 
over the southern Mainland.
