NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
845 PM PDT Tuesday Oct 21 2014 


Synopsis...a strong frontal system will move through western 
Washington tonight and Wednesday morning. Heavy rain will fall in 
the Olympics and north Cascades. The rain will turn to showers 
Wednesday night and Thursday. Another low pressure system will reach 
the area late in the week. 


&& 


Short term...at 830 PM the strong frontal system was just inside of 
130w and pressure gradients have been rising with windy conditions 
on the coast and in the north. Destruction Island was blowing a full 
gale and may reach storm force. With south-southeast winds the wind over land 
should be gusting to 50mph and there is a Wind Advisory in effect 
for the normally windier areas. The thunderstorms that were tracking 
into Vancouver Island have decreased as the precipitation has become more 
widespread and stratiform. The strong southerly winds aloft tonight into 
the Olympics should give around five inches of rain and a Flood 
Watch is in effect. The Skokomish River ought to reach flood state 
around 2am and a warning is in effect for that river. There is also 
a watch for the northern Cascades...but the bulk of the rain in the 
Cascades will probably hold off until late tonight through Wednesday morning. 
The rain becomes showery Wednesday evening as the front continues to 
slowly push southeastward. Breezy and showery weather can be 
expected Wednesday night and Thursday as onshore flow and a large upper trough 
continue to affect the area. Late in the week a deep low approaches 
the area...the latest NAM has a 988mb low tracks north-northeast into the southern 
Oregon offshore waters by daybreak Sat. 


Long term...the offshore low moves inland somewhere over the 
Pacific northwest on Saturday bringing wet and windy weather to the area. 
Post frontal showers decrease on Sunday...then another warm front 
and low appear to be on track to move across the area Monday and 
Tuesday. Model details differ...but it appears that next week will 
be wet and breezy with mountain snow levels decreasing to at least 
higher pass level midweek and temperatures in The Lowlands cooling 
off where highs struggle to get out of the lower to middle 50s. Albrecht 


&& 


Hydrology...a Flood Warning is in effect for the Skokomish River in 
Mason County. Flood watches are in effect for the olympic peninsula 
tonight and Wednesday...and for Snohomish County northward in the 
interior from midday Wednesday into Wednesday night. The rivers in 
the Cascades most likely to see flood stage are the stillaguamish 
river in Snohomish County and the Nooksack river in Whatcom County. 


&& 


Aviation...an upper trough will remain over the region through 
Thursday. A 990 mb surface low will track into central Vancouver 
Island early Wednesday morning. This system will bring strong flow 
aloft to western Washington. Moist and weakly unstable. Rain over the coast will 
spread inland by midnight...heavy at times through Wednesday. VFR 
ceilings inland and MVFR ceilings near the coast will deteriorate to 
widespread MVFR conditions after midnight. An isolated thunderstorm 
is possible...especially near the coast. 


Ksea...southerly winds 10-14 knots increasing to 15 knots west/ g25-30 knots after 
midnight through Wednesday morning...then easing. Rain increasing 
after midnight with ceilings predominately 3k feet but MVFR 2-2500 feet at 
times. Rain will be heavy at times Wednesday morning with visible down 
to 2sm. Dtm 


&& 


Marine...satellite and observation indicate low pressure off the Pacific northwest is 
deepening and on track to reach central Vancouver Island as a 990 mb 
low early Wednesday morning. The strong southeast pressure gradients will 
bring high end gale force winds to the coastal waters...with solid 
gales to the entrances to the Strait...Admiralty Inlet...and northern 
inland waters. Small craft winds to 30 knots are expected in Puget Sound 
sound/central Strait. Winds will ease first along the coast after 6 
am...then across the interior after 9-10 am. Seas over 15 feet are 
also expected today along with rough bar conditions. 


There will be a relative lull in the stormy weather in the middle of 
the week...then another strong weather system will affect the waters 
Friday and Saturday. A deep surface low is expected to track through 
the waters during this time but there is still a lot of uncertainty 
with how strong the low will be and where it will go. Dtm 


&& 


Sew watches/warnings/advisories... 
Washington...Flood Warning Skokomish River in Mason County. 
Flood Watch Mason...Clallam...Jefferson...and Grays 
Harbor counties tonight into Wednesday afternoon. 
Flood Watch Snohomish...Skagit...and Whatcom counties midday 
Wednesday through Wednesday night. 
Wind Advisory coast...Admiralty Inlet...San Juans...western 
Whatcom...western Skagit. 


Pz...Gale Warning coastal waters...entrances to the Strait of Juan
