NWS Forecaster Discussion




Southcentral and southwest Alaska forecast discussion 
National Weather Service Anchorage Alaska 
532 am akdt Tuesday Jul 22 2014 


Analysis and upper levels... 
a progressive split-stream pattern remains in place across the 
alaskan domain this morning. This pattern has been generally in 
place for almost 2 weeks...and features a progression of upper 
lows/troughs moving through interior Alaska and another separate 
progression of disturbances across the Aleutians and into the 
southern Gulf. Currently...a disturbance is moving onshore over 
northwest Alaska...with a southern stream upper low near Dutch 
Harbor. The axis of the ridge that made for such a nice day 
across southcentral yesterday has slid eastward...with deep-layer 
(but weak) southwest flow spreading into all of southern Alaska. 
A much larger ridge is beginning to take shape over the western 
Bering...where marine fog/stratus remain widespread. A few showers 
have moved onshore over southwest Alaska as both the northern and 
southern stream disturbances slowly approach the coast...though 
none are looking particularly impressive at this time. 


&& 


Model discussion... 
the models are in excellent overall agreement in the movement of 
the main weather features over the next several days. The ridge in 
the Bering Sea will continue to strengthen and will become the 
dominant weather-maker across the area. In the last 24 hours the 
models have struggled a bit with weather the ridge axis will be 
over the northwest Bering or the northeast Bering. This will have 
most significant impacts downstream across Mainland Alaska 
concerning amplification of shortwaves dropping down the front of 
this ridge. With the models trending a bit further westward with 
the ridge axis in the last 24 hours...not surprisingly a northern 
stream trough coming over the ridge now looks as if it will 
amplify and bring a round of steady rain to much of south central 
Alaska sometime in the Thursday night or Friday timeframe. Thus 
will trend the forecast this direction. Otherwise...with good 
overall agreement...the high resolution models were leaned on for 
small-scale details. 


&& 


Short term forecast... 


Southcentral Alaska... 
midlevel clouds will be on the increase today...but will not 
be a major detriment to another nice day overall. Increasing 
southerly flow behind the departing ridge will provide an 
additional kick to typical diurnal sea breezes around the region 
today...though not extreme by any means. Another impact of this 
broad southerly flow will be the possible movement of some low 
cloudiness from near Kodiak Island toward the north Gulf Coast 
later today. Meanwhile...with this high pressure/ridging nosing 
into the northern Gulf there is a chance southerly winds along 
the Copper River may join with a surging thermal trough and low relative humidity 
values...but with generally weak and slow-moving surface features 
it is most likely that both fire weather criteria (wind and rh) 
will not quite reach significant levels. By this evening cloud- 
cover will increase for most areas...with the presence of the 
upper low near Kodiak Island likely keeping some scattered shower 
activity along the coastlines and mountain ranges through the 
overnight hours and continuing into Wednesday. 


Southwest Alaska... 
moist onshore flow will intensify today as showers/rain become 
increasingly widespread. Marine fog/stratus is also likely to 
surge onto the coastlines with limited spread inland as well. As 
the upper low currently near Dutch Harbor moves toward Kodiak this 
afternoon there will likely be an increasingly convective look and 
feel to some of the showers along and west of the Aleutian 
Range...leading to locally heavier downpours. The main trough 
clears to the east by midday Wednesday...but models now indicate 
an additional shortwave dropping down the front of the ridge will 
bring another quick shot of rain through the area Wednesday night 
before the Bering ridge dries out the atmosphere more 
substantially for the end of the week. 


Bering Sea/Aleutians... 
high pressure in the region will only get stronger through the end 
of the week. This means less and less shower activity and more 
and more fog/stratus problems as we head into the weekend. 
Winds across much of the Bering will keep a northerly component 
over the coming days...which will allow the Pacific side of the 
Aleutian chain to see better conditions overall than the Bering 
side. This pattern looks to be locked in for the better part of 
the next week. 


&& 


Long term forecast from previous discussion... 
the long range pattern (thursday night through monday) will 
generally consist of a ridge over the central Bering Sea/Aleutians 
and a trough over the Gulf of Alaska and over northern Alaska. 
This will result in northwesterly flow aloft for the Mainland. A 
few systems will push through southern Alaska...bringing 
considerable clouds and some precipitation. Due to the direction 
of the upper flow and the fact that the main lows will be to our 
west and south...precipitation will generally be showery and 
accumulations are not expected to be very high. 


The wpc (weather prediction center) forecasts are generally a 
blend of the 00z GFS ensemble mean...the 12z GFS deterministic 
model (less influence as time increases until by day 8 it is not 
used at all)...and the 00z European model (ecmwf) ensemble mean. The GFS is 
weighted slightly higher than the European model (ecmwf). The afternoon forecast 
strongly leans toward the wpc guidance. 


&& 


Afc watches/warnings/advisories... 
public...none. 
Marine...none. 
Fire weather...none.
