NWS Forecaster Discussion




Southeast Alaska forecast discussion 
National Weather Service Juneau Alaska 
327 PM akdt Tuesday Mar 31 2015 


Short term...afternoon satellite image reveals a weakening 
low...about 1001 mb...over the eastern Gulf with a trough 
stretching southeastward from the low center to near haida gwaii and 
a weak ridge of high pressure builds across the southern 
Panhandle. Large area of rain showers wrapping around the low 
over the open ocean. Between the ridge and the low...southerly 
onshore flow 10 to 15 miles per hour prevail over the Panhandle with small 
craft level winds across northern Lynn Canal. Across the outer 
waters...south to southwest winds around 15 knots prevail with 
rough small craft level seas 8 to 12 feet due to long period 
southwest swells. Afternoon temperatures range in the lower to middle 
40s. 


Models remain in general agreement for the weakening low in the 
eastern Gulf this evening dissipates by early Wednesday morning as 
the ridge of high pressure continues to build over the Panhandle 
through late Wednesday. A developing low in the western Gulf on 
Wednesday afternoon will move eastward and push the ridge a little 
to the east. Refreshed the inherited forecast with the GFS and NAM 
for their good consensus. 


As the ridge continues to build...the small craft level southerly 
winds late this afternoon over northern Lynn Canal will diminish 
this evening. Expect no small craft level winds across the outer 
waters...but the rough seas will remain through Wednesday due to 
swells. A weak upper level shortwave trough across Southeast 
Alaska will continue to produce scattered to numerous rain showers 
on and off bases tonight and Wednesday. Due to ongoing rain 
showers and cloud cover...expect small diurnal temperature 
fluctuations with overnight lows mostly in the middle to upper 30s 
and Wednesday highs in the middle 40s. 


Long term...after a day of relative agreement in the long range 
in yesterday's am package...we return to general model 
disagreement after 4-5 days in today's package. Moderate front 
approaching the coastline at 03z Thursday is being pushed by upper 
closed low barging into the central Gulf with 1000 mb low surface 
reflection. The surface low...a tweak faster on the new model 
updates...slows rapidly after about 09z and then takes a turn to 
the southeast as it begins to slowly weaken late on Thursday. Front's 
main impact will be a moderate east-west pressure gradient and Small Craft Advisory- 
level southeast winds over mostly the southern Inner Channels during the 
day on Friday while much of the adjacent outer waters will have winds 
in vicinity of 30kt sustained for a period early on Thursday 
before the weakening takes over. This includes a brief barrier jet 
enhancement over the northwestern marine area. Inland/coastal winds 
will likely be sub- strong wind level through the event. Meanwhile on 
Thursday moderate rain will spread into the southern half of the 
Panhandle while lighter precipitation will cover much of the north. With 
the NAM amounts appearing to be overdone still have total values 
well over an inch to 2 inches over favorable areas of the south. 
Ec/NAM combo utilized for much of these early updates though model 
differences were minor. These included bumping hi temperatures upwards on 
Thursday by a couple degrees f. The low is slow to move out to the 
southeast on Friday and showers appear likely to linger over mostly 
the southern half of the Panhandle...especially if the persistent 
retention of energy to the south advertised by the GFS verifies. 


Saturday appears to be potentially mostly dry for all but southern 
areas on the current guidance as upper ridging generally takes 
over the Gulf...however this is where model guidance begins to 
diverge significantly. The ec brings a moderate wave 
southeastward through the Panhandle within the northwest flow 
aloft sun/sun PM...although weaker than previous runs. The Gem 
solution is for a track southeastward through the central Gulf 
with a stronger wave. Yet another solution is the GFS...which 
shows a weakening wave and front moving into the Panhandle from 
the west-northwest by Sunday night as strong troughing builds into the 
Aleutians. The latter is the one common general thread amongst all 
of the guidance... the timing is model dependent but generally 
faster than previous runs. An entrenched trough seems likely by 
Monday PM/tues. Anyways, the details of the late weekend/Monday wave 
are thus still up in the air. Given the model temperatures predicted for 
late weekend...snow is still a threat over the northern 1/3 of the 
Panhandle or so although the potential of an interior air source 
seems to be waning at this point. Thus any snow that does occur 
would likely be brief, especially with the continuing lack of snow 
cover inland below a couple thousand feet in elevation. Went with 
wpc grids from day 5 onwards with the amount of uncertainty 
present. These grids were based on a naefs/Gem combo with no input 
from the ec updates.
