NWS Forecaster Discussion




Area forecast discussion...corrected 
National Weather Service Seattle Washington 
600 PM PST Monday Dec 22 2014 


Corrected the watches/warnings/advisories section. 


Synopsis...rain chances will increase along the coast late tonight 
as a Pacific frontal system approaches the area. Periods of rain can 
be expected Tuesday and Tuesday night as the front moves slowly 
southeast across the area. An upper level trough will keep the rain 
going on Wednesday morning along with cooler conditions. Drier 
northwest flow aloft will give cooler weather Christmas evening through 
Christmas day with only a chance of showers. Weather systems will 
move southeast across the area Thursday night through Saturday 
giving some rain at times. 


&& 


Short term...weather pattern changes are occurring over the Pacific 
and the changes are causing difficulties in the various forecast 
models. The models continue to have a fairly good sense for timing 
of various short wave features as they move through western 
Washington through the weekend. But the models continue to be having 
significant problems with the details concerning the amplitude and 
exact position of a developing blocking ridge offshore. The problems 
are both model-to-model and run-to-run. There appears to be two 
culprits...a developing subtropical low north of Hawaii...and a 
deepening low over the far western Bering Sea. These two features 
have the potential to develop a large blocking ridge along about 
145w...which would allow modified Arctic air to eventually drop 
southward from the Yukon early next week...but if they do not 
develop much...could result in just high pressure and cool 
conditions over the area in the long term. The development will also 
impact the strength and track of several short wave 
features...especially Wednesday and beyond...as they drop southeast from 
the Gulf of Alaska onto the West Coast. Continue to expect the 
forecast over the next couple of days to be challenging...low 
skill...and dependent on details that cannot be resolved well at 
this point. 


A warm front sits from off the S coast of Oregon to a 1003 mb low 
near 48n 143w. Rain with this front will move onto the coast around 
or shortly after 12z then shift into the area during the morning. 
The cold front will move across the area Tuesday night. Expect about 
an inch of rain in the interior valleys and over an inch to nearly 
two inches along the coast and in the mountains over a 24 hour 
period ending 12z Wednesday. Freezing levels will rise to about 7000 feet 
in the warm sector Tuesday. 


The 12z and 18z model solutions both cool the air mass significantly 
behind the front late Tuesday night into Wednesday morning as 
precipitation continues to fall behind the front. Snow levels fall 
to around 1500 feet for a period Wednesday morning. At this time 
snowfall is expected to be confined to the mountain zones Wednesday 
morning...but we will need to watch for the possibility that the 
lower levels of the air mass cools slightly more and snow levels 
over the eastern Puget Sound sound lowlands and possibly the south 
interior drop to below 1000 feet. At this time forecasts will call for 
a rain event with temperatures just below 40 degrees in that area. 


The nam12 continues to show a few showers with low snow 
levels...about 1000 feet and possibly a bit lower...Christmas morning. 
Low and middle level flow would indicate that there is a chance of a 
convergence zone. Will wait to see the whites of the eyes before 
including this in the forecast at this time...will just indicate a 
chance of showers with temperatures in the middle 30s. 


A short wave trough is expected to drop southeast through the area 
Christmas evening. This feature is expected to be weak with most 
precipitation falling on the coast and in the south interior. Snow 
levels should be near 2000 feet as this feature passes. Albrecht 


Long term...the 12z and 18z GFS along with the European model (ecmwf) brings a 
stronger short wave trough the area Friday night or Saturday 
morning. All models show temperatures with this system just above 
snow concerns in The Lowlands. Still...the Friday night/Sat system 
may give the mountains some much needed snowfall. Behind Friday 
nights trough...the GFS builds a ridge along 140-145w that promises 
cool and dry weather for later in the weekend through next week. The 
operational GFS appears to bring cool air in quickly from the north 
while the parallel run is slower and stronger with a potential 
modified Arctic front. The Canadian solution would give a little 
snow and a stronger Arctic air mass to the area. At this point a 
model average was used that is not as cold as some model solutions. 
It will also be turning drier early next week. Albrecht 


&& 


Hydrology...a period of heavier rain and high snow levels on 
Tuesday is expected to be brief enough to not result in flooding 
across western Washington at this time. Flooding is unlikely later 
Wednesday through early next week. Albrecht 


&& 


Aviation...high pressure aloft tonight will flatten on Tuesday. A 
surface warm front will move into the area late tonight...followed 
by a cold front on Tuesday afternoon. Air mass somewhat moist and 
mostly stable...becoming moist at all levels Tuesday morning as 
widespread rain develops. Mainly VFR ceilings tonight with predominately 
MVFR developing Tuesday. 


Ksea...VFR through tonight with middle/high clouds more dominate. MVFR 
ceilings should develop Tuesday morning as rain increases along a front. 


&& 


Marine...west swell 10-13 feet will continue over the coastal 
waters. Winds generally less than 20 knots with higher pressure at the 
surface over the waters through this evening. 


A warm front will lift north across the area later tonight and 
Tuesday...bringing Small Craft Advisory winds to most areas except 
Puget Sound sound. Onshore flow strengthens behind the front Tuesday night 
with stronger westerlies in the Strait...northwest winds in admiralty and 
southwesterly winds over Puget Sound sound possibly reaching small craft. 


Some of the higher astronomical high tides of the year will be 
occurring this week along with slight tidal anomalies. It looks like 
minor tidal overflow is possible for areas along the inland waters 
around 6 to 7 am Tuesday morning...with a better chance of tidal 
overflow occurring with even higher tides Wednesday morning. Tidal 
overflow is also possible along the beach with high tides around 100 
PM Tuesday afternoon. A coastal Flood Advisory was issued for both 
the inland waters and coast...excluding areas along the Strait of 
Juan Delaware fuca. 


&& 


Sew watches/warnings/advisories... 
Washington...coastal Flood Advisory in effect for the coast and 
shorelines bordering the Puget Sound sound...Admiralty Inlet..and 
northern inland waters from 10 am to 4 PM PST Tuesday. 


Pz...small craft advisories are in effect for the coastal waters... 
entrances to the Strait of Juan Delaware fuca...northern inland 
waters...and Admiralty Inlet. 


Small Craft Advisory for rough bar in effect until 7 PM 
Tuesday for the Grays Harbor bar.
