NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
330 am PDT Friday Oct 24 2014 


Synopsis...a warm front offshore will produce locally strong 
east wind along the Cascade foothill early this morning. Another 
stronger low pressure system will bring locally windy conditions to 
portions of western Washington later today and tonight. It will also 
be wet with locally heavy rain possible. Sunday and Monday will be 
showery. More rain is expected Tuesday with another advancing 
frontal system. Wet and breezy weather is likely at times through 
the end of the week. 


&& 


Short term...a warm front lifted northward overnight and radar shows most 
the rainfall has shifted over extreme northern areas early this morning. 
The cross Cascade gradient continues to climb with sea-eat near near 
-7.5 mb at 3 am. The wrfgfs-4km shows gusty east winds along the 
foothill continuing into the morning hours before easing. Mesoscale west 
observation are showing gusts to near 35-40 miles per hour at sites around Enumclaw. 
With the climbing gradient the wind gusts should reach 45 miles per hour at 
times so the advisory remains in effect through 9 am PDT. The 
Bellevue zone was removed as stronger winds show no signs of 
extending that far. 


The main feature of interest is the low pressure system spinning off 
the northern California coast. Models appear to have a much better handle on the 
complex structure of this low as it organizes and moves NE toward 
our area. Its central pressure is already down to near 985 mb and a 
bit more deepening is possible over the next few hours given the 
numerous lightning strikes which often indicate a deepening system. 
These strikes are also occurring to the north/NE of the low which should 
generally tell the direction the low will track...in this case to 
the NE. 


Latest 00z/06z models are now in much better agreement so there is 
slightly more confidence that the low will consolidate rapidly today 
and track inland near Hoquiam. Even the 00z nam12 which was still 
bringing the low too far S for wind has shifted north with the low track 
on the 06z run...bringing it NE through Puget Sound sound this evening. 
Virtually all the other models show this consolidation and general 
track with only slight variations. The European model (ecmwf) is the most alarming 
with its more north-northeasterly track just west of Puget Sound sound resulting in lots 
of southerly gradient...+14 mb pdx-bli...all through way up to the north 
interior. This solution would probably give high end advisory for 
much or all of the interior. Most other solutions show a much 
shorter period of southwesterly winds with the initial sharp pressure rises 
behind the low late this afternoon and evening. The nam12 and 
wrfgfs-4km both indicate 3 hour pressure rises of +8 to +9 mb from 
the coast to the SW interior/Puget Sound sound region behind the low. 
Those models then surge the westerlies down the Strait and produce 
strong winds into Whidbey Island and maybe The Headlands of the eastern 
Strait. This scenario would cut off stronger winds to the S...so 
Puget Sound sound southward would have winds easing by midnight. Not all models 
agree on these details but this is the best guess scenario at this 
time. Will issue a Wind Advisory for the coast...SW interior...Puget Sound 
sound/Hood Canal...and the eastern Strait/Whidbey Island zones. Most 
models cut off stronger winds before reaching Everett so that zone 
will be left out of the advisory. Will also issue an Special Weather Statement to cover 
the rest of the area indicating breezy to locally windy weather 
possible...but sub advisory. At something will be in place in the 
event the European model (ecmwf) is correct in producing strong southerly gradient all the 
way up the interior. 




Strong Post-low onshore flow will prevail on Sunday with rain 
changing to showers. It will be noticeably cooler with highs only in 
the middle 50s...though it will feel colder given the breeze. 


Long term...the next system will approach the Pacific northwest on Tuesday 
with the advancing warm front bringing rain back into western Washington. Probability of precipitation 
were boosted as models mostly agree on this and rain shadowing will 
not be an issue. A 985-990 mb surface low will start to fill as it 
tracks east-NE across northern Vancouver Island by Tuesday night. This 
system will produce strong southeast pressure gradients so Wind Advisory 
level winds are probable from around Whidbey Island northward and along 
the coast. Gradients never turn southwesterly through Puget Sound sound so much 
less wind expected here. This will be a wet system with 24 hour rain 
amounts of 2-4 inches likely in the Olympics and 
Cascades...especially north. 


There will be a lull in showers between systems on Wednesday. 
However...it will not be completely dry. The 00z GFS/European model (ecmwf) are in 
better agreement on bringing another system into the area on 
Thursday. But models are implying this system will split...so it may 
not be well organized. There will be a chance of rain at times the 
rest of the week. 


&& 


Hydrology...the Skokomish River will rise again in response to 
heavy rain today and tonight. Since it is still running high from 
the previous rainfall...it is possible the river will get close to 
flood stage late today or tonight. For now the forecast takes the 
stage at Potlatch to between 15.5 and 16 feet. Flood stage is 16.5 
feet. 


A break in rain will help water recede on the Skokomish River 
Monday. However...another front will bring up to 2-4 inches of rain 
to the skokomish basin. Will need to keep a watch on this but 
current projections keep the Skokomish River below flood stage. 


Otherwise...flooding on other rivers is unlikely over the next 7 
days. 


&& 


Aviation...a cold front just offshore will move inland this 
morning...followed by an upper level and surface low this afternoon 
and this evening. The air mass will moisten with VFR ceilings this 
morning lowering to predominant MVFR ceilings with spotty IFR ceilings late 
this afternoon and evening. 


A surface low will move across Astoria around 21z and across West Washington 
00z-06z. Strong west-SW flow behind the low will produce gusty surface 
winds in spots...sw20-35g45kt. The air mass will become more 
unstable as the upper level low approaches...with isolated 
thunderstorms possible along the coast and over the SW part. 


Ksea...the terminal is in a lull at 11z between a warm front and the 
cold front just offshore. Rain will return 15z-19z as the cold front 
crosses the area. Precipitation will continue after that as the upper level 
and surface low follow. The air mass will become more unstable as 
the upper level low nears the area with isolated thunderstorms 
possible. Ceilings should gradually lower through bkn030-050 through 
around 22z then reach the MVFR range after that. Winds aloft 
fl050-fl100 will be S 30-55kt from 15z-00z. North surface winds will 
shift to southerly 5-10kt after 15z as the cold front approaches. 
Surface winds sw15-30g35kt will develop after 00z. Kam 


&& 


Marine...a 995 mb surface low associated with an approaching cold 
front will move NE across the coastal waters this morning. A 990 mb 
low will move NE across Astoria this afternoon and over Puget Sound sound 
late this afternoon. This is a bit of a complex pattern and models 
are not quite in lock step with respect to timing...track...and wind 
strength in various locations. Confidence is only moderate. The 
first low should raise southerly gales along the coast with Small Craft Advisory 
winds over parts of the inland waters. The second stronger low 
should generate west-northwest gales over the coastal waters and should raise 
full gales in the Strait this evening. Pressure rises behind the low 
should raise winds in Puget Sound sound but gales are a little more 
tenuous here. Models have the weakest Small Craft Advisory level winds over Admiralty 
Inlet and the north inland waters...but gales are not out of the 
question either. 


After the second low exits to the NE tonight...a surface ridge will 
gradually build inland over the region late tonight and Sunday. 
Another vigorous frontal system will approach from the west on 
Monday...then move inland Monday evening. Gales are possible for the 
coast and north interior. Kam 


&& 


Sew watches/warnings/advisories... 


Washington...Wind Advisory for the east Puget Sound sound lowlands through 9 am 
PDT this morning. 
Wind Advisory for the coast...southwest 
interior...east Puget Sound sound lowlands...and Puget Sound sound/Hood 
Canal from late this afternoon through tonight. 
Pz...Gale Warning coast...Strait and Puget Sound sound. 
Small Craft Advisory Admiralty Inlet and northern inland 
waters.
