NWS Forecaster Discussion




Southcentral and southwest Alaska forecast discussion 
National Weather Service Anchorage Alaska 
421 PM akdt Friday Sep 4 2015 


Analysis and upper levels... 


The Alaska domain is under the influence of mostly zonal 
flow...with weak jet streaks driving individual features but no 
coherent longwave features affecting the aor. The most significant 
surface feature is a developing low in the northeast Gulf of 
Alaska that is currently producing a gale-force barrier jet along 
the north Gulf Coast. The rest of the Mainland and 
Bering/Aleutians region experienced generally weak pressure 
gradients and corresponding light winds. Meanwhile...a few 
relatively weak upper level lows are spinning over the northern 
Bering as well as north of the y-k Delta...reinforcing unsettled 
weather and showers. 


A quick look at upper air soundings from this morning as well as 
currently satellite imagery reveals a stagnant and moist airmass 
in place across the forecast domain. With weak upper level 
shortwaves continuing to move east/northeast-Ward across the 
Mainland it is no surprise that shower activity is ongoing in most 
places. A weak and transient ridge of high pressure over the 
central and eastern Bering offers some hope to at least dry things 
out later today/tonight over the Mainland...but does not appear 
strong enough to significantly decrease the thick cloud-cover 
already in place. 


&& 


Model discussion... 


The models are in good synoptic agreement...not surprising given 
the somewhat stagnant and weak pattern the region is currently 
under. This type of pattern (high zonal index) usually results in 
numerous weak shortwaves moving quickly through the pattern...and 
so the numerical models struggle to agree on timing because things 
are moving so quickly. This current case is slightly different in 
the sense that there is no single/continuous jet stream moving 
through the area...and so individual features are moving a little 
slower than they normally do. As a result...while there are some 
differences in timing and placement over the next few days...the 
models are also in decent agreement on some of the smaller scale 
features affecting the area. The most significant of these will 
be the weak upper low currently over the northern Bering that will 
slowly move across the akpen and into the Gulf by the end of the 
weekend. Models are all trending a bit further south with this 
low...which promises to bring an increase in rain/shower activity 
from Bristol Bay and the Kenai Peninsula southward...but which may 
now stay mostly south of the Anchorage area. The NAM is the 
preferred model due to its higher resolution...but none of the 
models showed huge differences today. 


&& 


Hydrology... 


The release of the snow Glacier-dammed lake in the mountains of 
the Kenai Peninsula has ended. Water levels on Kenai Lake and the 
upper Kenai River have crested...and a diminishing pulse of water 
will now be moving into Skilak Lake and eventually into the lower 
Kenai River. All flood waters are now receding...and no additional 
flooding is expected. 


&& 


Short term forecast southcentral Alaska (days 1 and 2)... 
a generally cloudy and showery pattern will persist through the 
weekend beneath weak upper level flow as the most active weather 
remains confined to the southern Gulf. Shower activity will 
gradually diminish in coverage tonight through Saturday as the low 
over the eastern Gulf moves away from the area and weak transitory 
ridging begins to build in from the west. This will also promote 
patchy fog throughout the Cook Inlet region tonight as abundant 
low level moisture remains in place...but lingering cloud cover 
should help to inhibit more widespread fog development. Shower 
activity will then begin to increase again by Sunday as an upper 
low moves across Kodiak Island and into the southern Gulf. The 
more southern track of this system will keep the bulk of the 
precipitation focused along the Gulf Coast with more sporadic 
activity inland. 


&& 


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


Ridging spreading across the area will cause shower activity to 
diminish tonight. However...the upper low digging southeast 
across the Bering will bring back rain Sat afternoon. This will 
become showery Sat night into sun as the upper low transits into 
the Gulf...and precipitation will taper off Sun afternoon as the 
next ridge arrives. 


&& 


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


Showers and areas of fog will persist over the eastern half of the 
area as a short wave moves from the Bering into the Gulf. In the 
west...a front will move across the western and central Bering 
through sun. It will be accompanied by areas of dense fog and 
steady rain...along with small craft level winds. 


&& 


Long term forecast (days 3 through 7)... 
an upper level low over the Alaska Peninsula will track further 
eastward into the Gulf...with weak ridging briefly developing over 
the eastern Bering and southwest coast in its wake. This 
transition will diminish showers and keep near normal temperatures 
over the southern Mainland through Monday morning. Models continue 
to struggle with another upper level low quickly tracking into the 
Bering Sea from the west and eventually joining forces with an 
Arctic trough digging over the eastern Bering by Tuesday...before 
tracking further inland by midweek. The 12z European model (ecmwf)...which is the 
preferred model for this forecast package...depicts a much broader 
trough over the Bering...which eventually swings over to the Gulf 
later next week. By the end of the week and into the weekend...the 
European model (ecmwf) shows the upper low remaining stationary over the western 
Mainland...as a North Pacific low tracks up along the Alaska 
Peninsula Friday night and into the Gulf Coast by Saturday. The 
net result will be an increase of wet and windy conditions over 
parts of the southern Mainland through the end of the week...and a 
surge of colder air filtering in over much of the Bering and 
Aleutians behind the trough. However...how far east into the 
southern Mainland this colder air will push into...and when/where 
the bulk of the precipitation will end up is still in 
question...as models continue to struggle with the timing and 
strength of the above mentioned systems. Thus leaving a lot of 
uncertainty and lower confidence in the long range forecast.
