NWS Forecaster Discussion




Southeast Alaska forecast discussion 
National Weather Service Juneau Alaska 
503 am akdt Thursday Oct 30 2014 


Short term...sharp trough aloft prevails through the period, 
while at low levels the scenario is somewhat more complex as usual. 
Relaxing gradients today the wake of the eastern Gulf low will likely 
restrict scas to offshore waters and winds will generally decrease 
at low levels with the exception of the far northwest which will 
see some localized winds. The lighting activity tonight has been 
restricted to south of haida gwaii but models pose threat to the 
central offshore areas for isolated convection this afternoon and 
tonight and also the threat will exist for western portions of 
chichagof and Baranof islands. The main current low...995ish mb 
west of Sitka...drifts north and west while maintaining its 
strength. Along with the southerly low-level jet trailing off to 
the southeast along the Panhandle a moderate rain scenario is 
likely today especially over coastal regions throughout. This 
latter trough is maintained through the period but that is where 
model solutions differ with the NAM being the outlier both in 
precipitation and wind...the trailing trough is stronger on that model 
and includes a secondary low...leads to moderate precipitation over the 
north for late tonight/Friday morning and wind increases. We aren't buying 
that as the ec/Gem/GFS models agree to simply maintain the trough 
and predict a slow nwwd drift of the northern low while increasing 
onshore moist flow into the Panhandle in the 09-15z period 
Friday...with no secondary low formation. Thus winds are likely to 
be sub-Small Craft Advisory level through much of the interior channels after winds 
weaken rapidly today. Then after about 06z the gradient begins to 
increase for the central Panhandle as southwesterly flow begins to 
increase south of the main low and also in response to a west-northwest upper 
jet entering the central Gulf late. This pattern is progressive as 
upper shortwave ridging is evident over the western Gulf early 
Friday. This scenario will likely lead to a wet Friday for most 
areas with possible Small Craft Advisory winds for north/central channels. For grids went 
with a blended ec/Gem/GFS approach on pressure wind and precipitation 
fields. This includes precipitation persisting through the period over most of 
then north but abating over the south later today. Temperatures 
continue to be warm enough to maintain rain at low levels over all 
but the northern fringes and Hyder...where a mixed scenario is 
likely. Model confidence...using the ensembles mentioned...is 
average for the short-term. 


Long term...the first in a long series of shortwave troughs is 
forecast to move onshore across southeastern Alaska during Friday. Residual 
pocket of cold midlevel temperatures will initially support 
showers...with a transition back to stratiform over the Gulf as 
warmer midlevel temperatures spread eastward. This warmer airmass will 
be accompanied by a frontal boundary at the surface...which will 
advance east-northeast across the Gulf Friday afternoon...and then move onshore 
Sat morning. Widespread rain will be probable along/ahead of the 
front...with moderate to heavy rates possible over the southern 
Panhandle where strongest moisture flux will be present. 


In addition to the rain...a 40-50 knots low-level southeasterly jet is 
forecast to occur immediately ahead of the front. This feature 
will reside over the outside waters Friday night...favoring gale 
force winds. The low level jet then moves onshore late Friday night into Sat 
morning...aiding in gale force winds for Clarence Strait...and 
possible strong gusty winds for land zones 23 /Sitka/...27 
/Hydaburg/...and 28 /Ketchikan/. The combination of strong winds 
and locally heavy rain may increase the threat for mudslides. 


Upper troughing persists over the western/central Gulf through the 
middle of next week...with numerous embedded impulses ejecting east-northeastward 
across the Panhandle...the most vigorous of which will potentially 
spin up a surface low over the southeastern Gulf on Monday. If this scenario 
does indeed unfold...then winds over the southern inside waters will 
reintensify to small craft/gale...and another period of 
moderate/heavy rain will be possible over the southern land areas. 
However...model spread is large for the Monday time period...thus 
confidence is not high regarding wind and heavy precipitation potential. 


In general...models show much improved consensus in the large- 
scale details throughout the long term period. This gives 
confidence in the likelihood for an extended period of wet weather 
over southeastern Alaska due to numerous upper waves passing across the 
region. No change was made to pressure grids through 00z Monday. 
Thereafter...blended in the latest European model (ecmwf)...which resulted in a 
deamplification of low pressure in the southeastern Gulf Sun night into 
Monday. Pop/quantitative precipitation forecast grids were refreshed with the GFS and European model (ecmwf).
