NWS Forecaster Discussion

Southeast Alaska forecast discussion 
National Weather Service Juneau Alaska 
403 PM akdt Friday Oct 9 2015 

Short term...a strong storm over the eastern Gulf will move north and 
onshore near Cape Fairweather while weakening rapidly this evening. 
A smaller low will move NE across haida gwaii Sat. A trough will 
move north across the central and northern Gulf Sat. Primarily used the 
12z gfs22 as it looked like best model for both systems at this 

Main forecast concerns will be winds and precipitation potential/amounts. 
The strong storm tracked a bit further west than previously indicated 
and this caused winds to drop below warning levels over the S this 
afternoon...and kept winds from reaching warning levels in the 
Central Area. Ended up dropping the warnings with early afternoon 
update. Still...will have strong winds for most of the area at 
some point tonight. The southern area winds will drop off this 
evening...while the northern areas increase this evening then drop off 
late tonight or early Sat morning. A small area of storm force 
winds occurring over far eastern offshore waters...but these will 
diminish rapidly tonight as low weakens and moves away from that 
area. Winds should continue diminishing over the northern Inner 
Channels Sat...while southern areas pick back up some in response to 
low moving across haida gwaii. Do not expect Small Craft Advisory level winds with 
this smaller system in the southern area though. The western parts of the 
Gulf marine waters will see Small Craft Advisory level winds with the trough moving 
northward through the area...especially closer to the north Gulf Coast. 

As for precipitation potential...most of the area will start tonight wet 
but rain will diminish over much of the S tonight. However...more 
rain will likely move back into the far southern area Sat ahead of the 
low moving toward haida gwaii. The northern Panhandle area will stay 
wet tonight but see precipitation diminish Sat as they will be in between 
systems. The NE Gulf Coast should be wet much of the 
time...with precipitation from the weakening storm tonight and the trough 
moving north to that area Sat. Rainfall amounts will generally be up 
to 3 inches for the rest of the night...heaviest over the higher 
terrain over the central and northern Panhandle. Even with this 
rain...not expecting any flooding issues...although a few streams 
could reach bankfull this evening before dropping off overnight. 
Rainfall Sat could get near an inch in some areas over the far S 
while the remaining area sees generally under 1/4 of an inch. 

Long term...now that the current Gulf storm is waning...we will 
have another to wax. While there is not much to speak of on 
satellite except the beginnings of a baroclinic Leaf forming 5 to 
10 degrees south of the central Aleutians...a deformation band 
will follow the jet around the base of the jet and interact with a 
strong temperature gradient oriented around 45 north. As the def band 
follows the jet towards the northeast it will spin rapidly as it 
reaches the left exit region of 100 knots-plus jet. However, guidance 
is more conflicted than yesterday with the position and track 
falling into two basic camps...an American Camp comprised of the 
GFS/NAM taking a delayed track closer to southeast shores, and 
potentially more impactful for land areas as well as a 
Euro/Canadian track that supports the storm pulling away from the 
coast and pushing more towards the central Gulf. Strengths vary as 
well with the international models more enthusiastic for a deeper 
low below 960 mb. For this reason, we felt the current forecast 
taking a middle ground was still appropriate as uncertainties have 
risen today. What we did change was extend the winds into Sunday 
night. All models suggesting this storm will take longer to wind 
down. Thus gales have been extended. While a high wind watch was 
not issued today...there is still fair potential for high wind 
gusts of 60 miles per hour plus from Annette Island northwest to Baranof 
Island...including Prince of Wales on Sunday. 

There is also potential for some heavy rain bands with some 
connection to subtropical latitudes. But the North American 
ensemble members are not nearly as impressed with this system as 
the current one in the Gulf. In addition...as some models are 
tending to track it westward...if anything heavy rain may be 
limited for the south and delayed for the north. Stream behaviors 
tonight will help dictate our predictions for Sunday. The ground 
should be primed right now...having fully saturated from the low 
water levels during the five to six day drying period ending 
Wednesday/Wednesday night. The southern Panhandle likely will be 
the spot to watch for Sunday/Sunday night. But at this point...no 
flooding is expected. 

Looking at the extended...the Sunday/Monday low weakens in the 
northern Gulf or moves ashore allowing sufficient cooler more 
unstable onshore flow to support showers into midweek. There are 
some signs that another deeply baroclinic system moves north into 
the eastern Gulf late next week. 

We nudged winds toward European model (ecmwf) for Sunday night into Monday to 
extend the higher winds in time over the Gulf. Used wpc guidance 
which was based off of both Euro and GFS emsembles. Forecast 
confidence average.
