NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
900 am PST Wednesday Dec 17 2014 


Synopsis...a weak Pacific weather system will bring some areas of 
light rain to western Washington through Wednesday night. A stronger 
Pacific frontal system is expected to move ashore Thursday night 
with more significant rain. Another wet weather system is forecast 
for this weekend with heavier rain amounts along the coast and in 
the mountains. 


&& 


Short term...models are not handling the northern stream portion of the 
split trough affecting western Washington all that well. The elongated 500 mb 
trough axis is offshore just inside 130 west and there is still some 
surface structure left according the hrrr which most models do not 
show. The hrrr from yesterday afternoon is the Winner which was 
showing southerly flow entraining some moisture from the southern stream system 
into western Washington early this morning. Radar now shows light rain around 
much of western Washington including Puget Sound sound. Some models like the gfs40 
were mostly dry and still show only light quantitative precipitation forecast fields west of the sound 
and across the far north and Cascades. The hrrr does dry out the 
interior by late morning before spreading some light rain back into 
the area early this evening like the nam12 shows. This timing is 
questionable given the bright clouds on infrared imagery approaching the 
coast coupled with the Langley Hill radar showing more rain bands 
along the coast lifting NE. Will maintain the current likely probability of precipitation 
for today and tonight. 


The 500 mb trough axis finally shifts east of the area by 12z Thursday 
morning. With light flow and a short wave ridge traversing the 
area...expect low clouds and maybe some fog around the area. This 
will break up by midday as the next stronger front approaches 
increasing the flow out ahead of it. Timing is still tricky with the 
06z GFS bringing rain as far inland as the western portion of Puget Sound 
sound by late Thursday afternoon. The nam12/European model (ecmwf) are similar but 
the Canadian is still running a few hours faster with rain 
overspreading western Washington earlier in the afternoon. Will leave probability of precipitation 
unchanged for now but may consider removing some of the interior 
probability of precipitation for a dry period Thursday morning. This would probably result 
in more fog around the area. 


The warm front moves through quickly with colder air arriving with 
the main frontal band slated for Thursday night. This system appears 
to split less than previous fronts and the southeast gradients are tight 
over the area so expect locally windy conditions north of Puget Sound 
sound and along the coast. Snow levels will fall from near 5000 feet 
to 3000 to 3500 feet by later Thursday night and Friday morning. 
There is a 6 hour window of stronger flow along and behind the front 
which could squeeze out several inches of snow even down to some of 
the passes. Ski resorts could possibly get close to 6 inches of snow 
which is borderline advisory criteria. Mount Baker may get the 
higher amounts in this pattern. Precipitation will fall as just rain 
in The Lowlands...changing to showers during the afternoon. Any 
break in precipitation will again be short lived as a strong 180+ knots 
jet across the Pacific drives wetter storms toward the area by 
Saturday. Mercer 


Long term...no updates from previous discussion...looks like a 
short break in the weather Friday night before the next wetter 
system arrives over the weekend. This system was currently moving 
across 150e this morning with a supporting 200 knots jet. The forecasts are 
still trending a bit drier with this system given its more 
progressive nature. Expect rain to increase on Saturday with the 
warm front and the cold front moving onshore Sunday night. 


Ridging aloft along the West Coast means the jet stream will be at 
our latitude with a westerly component into the Cascades and 
shadowing off the Olympics this weekend. The coast and mountains 
should get the bulk of the precipitation. 


Another short break Monday before the next not as wet system arrives 
Tuesday. The forecasts continue to suggest a Kona low developing but 
they are inconsistent in its position. The further west usually 
results in building an upper ridge near 150w or 160w and producing 
northerly flow aloft into the Pacific northwest for a much cooler flow 
pattern. Further east with the pattern and the Pacific northwest gets a 
milder northerly flow aloft. Stay tuned here. Buehner 


&& 


Hydrology...no updates from previous discussion...river flooding is 
not expected through Saturday. Moist westerly flow will develop 
Saturday night and continue through Sunday night...with heavy 
mountain rain amounts possible. Guidance is now showing a bit 
lighter amounts given the more progressive nature of this system. 
Primary concern for any river rising above flood stage is the 
skokomish but also need to keep an eye on other Cascade flood prone 
streams. Buehner 


&& 


Aviation...a stretched out and weakening upper level trough along 
the coast is moving onshore this morning and will be followed by 
another one...currently along 132w...tonight. At the surface...high 
pressure east of the Cascades combined with lower pressure over the coastal 
waters is giving light offshore flow. The air mass is moist and 
stable with light S to SW flow aloft. 


Pacific northwest radars show bands of light rain extending SW from western 
Washington into the Oregon coastal waters. This moisture is moving 
NE ahead of the incoming weakening troughs offshore. Most 
terminals in the interior are seeing VFR ceilings and visibilities 
despite the light rain as a result of the offshore pressure gradients. 
The exceptions are at kclm where precipitation and flow moving onto 
the north slopes of the Olympics is producing a lower stratus deck 
and around kolm where precipitation in the more trapped southwest 
interior is producing low IFR stratus and visible 3-5sm br. 


The offshore pressure gradients are expected to slowly relax through 
tonight as the stretching and dying troughs offshore move into the 
area. This will result in generally deteriorating ceilings and 
poorer visibilities as we move into the tonight and Thursday morning 
periods. Expect areas of IFR conditions 06z-18z Thursday at many of the 
terminals in western Washington. Albrecht 


Ksea...expect ceilings around 040 through this evening with periods of 
light rain. Ceilings will fall to 008-012 after 05z this evening and 
continue until 18z. Expect visible to generally remain above 5sm in occasional 
-ra. East wind around 5 knots becoming southeast tonight. Albrecht 


&& 


Marine...weak troughs of low pressure...one over the coastal waters and 
another over the offshore waters...will stretch out and die as they 
move into the waters this afternoon through tonight. Expect light 
offshore flow. With seas over the coastal waters remaining around 10 
feet...the Small Craft Advisory for hazardous seas was extended into 
the nearshore coastal waters. Seas will subside late this afternoon 
and tonight. 


A strong Pacific front associated with a 960 mb low centered near 
49n 159w will approach the offshore waters on Thursday...then move inland 
Thursday night. A period of gale force winds can be expected over the 
coastal waters later Thursday afternoon through Thursday night ahead of and with 
the front. A gale watch is in effect for the coastal waters for Thursday 
afternoon and night. These will likely be upgraded to warnings this 
afternoon. 


The fetch area to the south of the low near 49n 159w is moving with 
the wave field it is producing. The wavewatch model continues to 
forecast seas 40-45 feet around 47n 150w by late tonight. These waves 
are expected to decay into an energetic 20-22 feet at 18-20 second swell 
on the Washington coast late Friday afternoon and Friday night. As it 
turns out...tidal anomalies along the coast are just over 1 feet above 
normal and high tide occurs early Sat morning. If swell remains high 
into Sat morning...some coastal flooding is possible along portions 
of the coastal waters. It is too early to tell at this point and too 
early to issue any coastal flood watches...but interests on the 
coast are urged to keep up with latest forecasts. 


Another strong warm front will arrive on Sat and will likely result 
in a period of gale force winds over the coastal waters...the north 
inland waters...and the entrances to the Strait of Juan Delaware fuca. 
Albrecht

Small Craft Advisory today for rough Grays Harbor bar.
