NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
300 PM PDT Wednesday Sep 19 2014 


Synopsis...a strong high pressure ridge will build over the region 
tonight and Saturday. Sunny skies will develop on Saturday after 
some areas of morning low clouds and fog. Marine clouds and cooler 
air will reach the coast on Sunday but the interior will remain 
sunny and warmer. A weakening system on Monday and Tuesday will 
bring in some clouds...a few showers...and moderating temperatures. 
A large upper level trough will produce a wetter and cooler pattern 
Wednesday through the end of next week. 


&& 


Short term...latest radar loop this afternoon shows just a few 
residual showers across the north interior north of Everett. The air mass is 
beginning to stabilize so showers will come to an end by this 
evening. Visible satellite trends show some partial clearing across 
southern portions of the interior but the lower levels are still rather 
moist across The Lowlands. High pressure aloft will rapidly build 
over the region tonight through Saturday with large scale 
subsidence. MOS and NAM time-heights/buffer sounds are showing a 
subsidence inversion to develop overnight suppressing any residual 
moisture within the lowest 1500-2000 feet. The gradients turn 
northerly later tonight but the flow will probably not strong enough 
to clear out moisture initially. However...thermally induced low 
pressure will form just off the coast in the afternoon increasing 
offshore flow conditions. This should clear out remaining moisture 
and give sunny skies across the area Saturday afternoon. High 
temperatures will warm several degrees well into the 70s but 
probably will not hit potential highs inland because of the cloudy 
start to the day. This will not be the case near the coast where 
Saturday should be the warmest day...just ahead of the marine 
stratus surge approaching from the S. Hoquiam and Forks could both 
reach the low 80s. 


The upper ridge shifts further inland on Sunday becoming centered 
over the Great Basin/rockies. Thermally induced low pressure near 
the coast in the morning will migrate inland over the interior 
lowlands of western Washington. This means light surface flow but increasing southerly 
850 mb flow which should aid in the warming process. Forecast highs 
will remain a couple degrees above the warmest NAM MOS given the 
overall pattern. Stratus will be nosing northward along the coast during 
the day bringing cooler marine air to coastal spots. Highs there 
will struggle to reach 70. Inland temperatures could reach the middle 
or even upper 80s in places...but cooler near the water. 


500 mb height falls continue Sunday night and Monday as the first in 
a series of fronts try to push into the area. The main affect will 
be to induce a marine push which will flood stratus and cooler air 
inland. Highs on Monday will struggle to reach the low to middle 70s 
assuming some spots around the SW interior/far S sound get some sun 
breaks. The front itself will be rather weak but most models do show 
some spotty light quantitative precipitation forecast around western Washington Monday afternoon/evening. 


Long term...the GFS/European model (ecmwf) have trended toward a partial break 
between weather systems on Tuesday. This is different from past runs 
and completely removing precipitation does not yet seem prudent. 
Probability of precipitation were removed for the interior Puget Sound sound region but kept a 
chance of rain in the forecast mainly west of Puget Sound sound in case the 
next system arrives a bit faster. 


A pattern change will slowly unfold midweek as a large trough 
develops over the NE Pacific sending a series of fronts into the 
area. The pattern now looks more amplified compared to the moist westerly 
flow pattern that was shown by runs a couple days ago. 
Nevertheless...the upper low will send waves into western Washington through the 
end of the week. Timing these is not really possible given the 
progressive pattern so probability of precipitation are higher middle week then taper to chance 
by Thursday and Friday just due to inherent uncertainty out to day 
6/7. Mercer 


&& 


Aviation...westerly flow aloft tonight will become SW as an upper 
level ridge builds in to the southeast of the area. At the 
surface...high pressure will build over southern British Columbia 
late tonight and Saturday giving increasing northerly flow at the 
low levels. The air mass is stable. Areas of low level moisture will 
develop below a low level inversion late tonight into Saturday 
morning. 


Residual stratus and reduced visibility in drizzle and light fog 
along the coast and over the north interior are decreasing rapidly 
from the south this afternoon. Expect pressure gradients to become 
light this afternoon then northerly tonight as high pressure 
strengthens over British Columbia. 


Increasing northeasterly flow from about 2500 to 5000 feet mean sea level 
tonight combined with subsidence with building high pressure aloft over 
the Pacific northwest will result in the development of a low level 
inversion that will strengthen and lower 09z-18z Saturday. The 
increased subsidence in conjunction with radiational cooling will 
concentrate low level moisture in an increasingly shallow boundary 
layer resulting in the rapid development of stratus and some fog 
around 09z that will likely burn off around noon Saturday. Expect 
areas of ceilings below 005 Saturday morning in the interior with some 
dense fog in areas where the stratus intersects the ground. This is 
not an uncommon occurrence during the early fall months and is shown 
well in the latest nam12 solutions. The 12z uw wrfgfs 4 km 
solution's column integrated cloud water product also shows this low 
level moisture Saturday morning. Coarser large scale models were not 
used as they tend to lose track of the low level moisture in these 
situations. 


Skies will rapidly clear midday on Saturday resulting in good VFR 
conditions. Albrecht 


Ksea...expect good VFR conditions through 09z. Low stratus with ceilings 
003-005 are expected to develop around and to the north of the 
terminal around 09z then spread into the terminal area before 12z as 
a subsidence inversion develops over the area and trapped low level 
moisture condenses with radiational cooling. There is about a 50 
percent chance that visibilities at the terminal will drop to below 
1/2sm fog if the stratus bases are slightly lower than currently 
expected. The stratus will likely break up around 20z Sat. Southwest 
winds 5-7 knots late this afternoon will become north 6-8 knots after 05z. 
Albrecht 


&& 


Marine...surface high pressure will develop over southern British 
Columbia tonight then strengthen Saturday and Saturday night. This 
will increase low level northerly flow late tonight through Saturday 
night. 


Flow will become more easterly late Saturday night into Sunday as 
the high over British Columbia moves southeastward. Small Craft 
Advisory east winds are likely at the West Entrance to the Strait of 
Juan Delaware fuca and the adjacent coastal zone late Saturday night into 
Sunday morning. 


A weakening front will approach the coastal waters late Sunday into 
Sunday night. The approach of the front will likely induce a 
southerly surge over the coastal waters Sunday into Sunday night. 


A much stronger frontal system well offshore will be approaching 
from the west Tuesday and Tuesday night and may result in some gale 
force winds over portions of the coastal waters during the middle of 
next week. Albrecht
