NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
315 am PDT Tuesday Aug 4 2015 


Synopsis...an upper trough will be over the area through midweek. 
Weak high pressure aloft will move overhead late in the 
week...followed by another upper trough next weekend. 


&& 


Short term...an upper level trough with a low center over b.C. Will 
continue to dig southward today lowering heights over western Washington. The height 
falls and continuing onshore flow will result in even cooler high 
temperatures today...especially across the interior with mainly 70s 
forecast. Satellite fog/stratus imagery shows areas of higher based 
7-8k feet clouds developing over the north Puget Sound sound region near the eastern 
Strait with some lower stratus forming over the SW interior and far 
S sound. The lower stratus surge normally expected with an upper 
trough induced onshore push is not very widespread at 2 am...though 
the north coast and SW interior/S sound are seeing some patchy low 
clouds forming in place. Will play with the cloud wording a bit to 
indicate areas of morning clouds. Partly sunny to mostly sunny skies 
will develop during the afternoon but this could be a slow process 
given the increasing onshore gradients. 


Models show more southwesterly onshore gradients later tonight/Wednesday 
morning which would be better for brining more solid low clouds into 
the interior. Will stick with the mostly cloudy start to the 
day...with partly sunny skies again in the afternoon. The trough 
axis will be over the area with 500 mb heights down near 5700m so 
Wednesday may end up the coolest day of the week. There could also 
be some patchy morning drizzle on the coast. Models show a secondary 
trough axis digging southward across western Washington during the afternoon so will 
maintain a threat of showers...though quantitative precipitation forecast amounts should remain 
light. Showers may linger into the evening as the trough pulls east and 
the flow becomes more northwesterly. There could even be a brief convergence 
zone over central/north Puget Sound sound. 


500 mb heights rebound on Thursday as the low pulls east and a ridge 
offshore moves toward the area. Low level northwesterly onshore flow will 
prevail but weaken during the day. The trend should be toward 
slightly warmer temperatures...reaching the middle 70s to lower 80s 
around Puget Sound sound and the SW interior. 


Long term...virtually all the models show the transitory ridge 
shifting eastward Thursday night and Friday. An upper low will approach 
with lower heights by later in the day. The main onshore influence 
will not be felt until the weekend so another partly to mostly sunny 
day appears likely. Highs should reach slightly above average...into 
the low 80s around Puget Sound sound and the SW interior...cooler near the 
water and toward the north interior/coast/Strait. 


Long range models disagree on the timing...strength...and track of 
the upper low for the weekend. The general idea is that upper 
heights will trend lower and onshore flow will increase once again. 
This should introduce more clouds and a threat of showers to western Washington. 
Made little change to the extended which has a chance of showers 
indicated at times. This can be fine tuned once the 
GFS/ECMWF/Canadian come into closer agreement. Temperatures will 
probably cool back to near average or even slightly below. Mercer 


&& 


Aviation...a large upper level low will remain centered over 
central British Columbia through this afternoon with an upper level 
trough extending S over West Washington. Flow aloft will be westerly. 


Strong low level onshore flow developed across West Washington last night 
bringing cooler marine air inland. The onshore flow was strong 
enough for the lower air mass or marine layer to be fairly deep and 
well mixed. In addition there was very little actual stratus present 
on the coast last evening. This should produce areas of mainly MVFR 
ceilings this morning...which should burn off by 19z. 


Another round of onshore flow tonight will bring more marine air 
inland overnight. Then the b.C. Upper level low center will move 
down over S b.C. On Wednesday. There may be more widespread MVFR 
conditions and a few showers as well. 


Ksea...bkn022 stratus was starting to form over ktcm and kgrf at 09z 
so stratus should form at ksea by 12z. Ceilings will be MVFR broken-ovc015- 
025 and should burn off around 18z. Surface winds will be S-SW 3-8 
knots today. Kam 


&& 


Marine...a large persistent surface ridge centered well offshore... 
combined with lower pressure over East Washington will produce moderate to 
strong onshore flow through this week. The westerly onshore flow 
will be strongest during the late afternoon and evening hours in the 
central and east Strait of Juan Delaware fuca. 


Last nights gales in the Strait eased quickly and now winds have 
eased below Small Craft Advisory levels. The GFS is indicating a similar pressure 
gradient through the Strait tonight and the Canadian lam also shows 
gale force winds...so a gale will be in effect tonight. The north part 
of Admiralty Inlet has a good chance at getting Small Craft Advisory level winds 
again tonight...so a Small Craft Advisory will be in effect. 


The leftover borderline Small Craft Advisory for northwest winds over the outer coastal 
waters will be allowed to expire late this morning. Mesoscale models 
show the winds easing below 20 knots...and with no observed wind data 
from the area I will go along with the model solutions. 


The GFS has the onshore flow a little weaker Wednesday night through 
Friday night so winds in the Strait will probably remain in the Small Craft Advisory 
range. However there is always a chance of a brief gale during these 
events. Kam 


&& 


Sew watches/warnings/advisories... 
Washington...none. 
Pz...Gale Warning central Strait and East Entrance tonight. 
Small Craft Advisory Admiralty Inlet tonight. 


Small Craft Advisory coastal waters Cape Flattery to Cape 
Shoalwater 10 nm to 60 nm through 11 am PDT.
