NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
330 PM PST Sat Dec 20 2014 


Synopsis...strong moist flow will continue tonight and Sunday for 
rain at times. An upper level ridge will build over the region 
Monday for drier weather. A cold front will slide southeast through 
the area on Tuesday. A cool upper trough will cross western 
Washington on Wednesday. Dry northerly flow will prevail on 
Christmas day. 


&& 


Short term...warmer air will surge inland this afternoon and 
evening with snow levels rising to 5000-7000 feet. Snow will change 
over to rain in the passes. Strong westerly flow will prevail 
tonight with heavy rain continuing in the mountains. This will lead 
to possible river flooding and a Flood Watch remains in effect. 
Whatcom and Skagit counties were dropped from the watch as precipitation 
amounts are not high enough to force flooding. Models show Seattle 
in the rain shadow tonight due to westerly downslope flow off the 
Olympics...rainfall totals will be light if anything. 


Strong westerly upslope flow will continue on sun with more heavy 
rain across the west slopes of the mountains...the threat of river 
flooding will continue. An upper level ridge will then build inland 
Sun night with heavy precipitation tapering off. The ridge will remain in 
place on Monday for drier weather. 


Models show the ridge flattening on Tuesday while a baroclinic zone sits 
over northwest Washington and southern b.C. This system may bring more rain to the 
north coast...Olympics and north Cascades. This baroclinic zone will 
then slowly shift S/southeast Tuesday night as an upper level trough digs 
offshore. 33 


Long term...a cool upper level trough will Cut Through western Washington 
on Wednesday for cooler weather and more showers. Snow levels will 
drop to around 2000 feet. Dry northerly flow will prevail on Christmas 
day for mainly dry weather...with just isolated showers in the 
Cascades. This pattern will continue into Friday. Models then show 
another cool upper trough crossing the Pacific northwest on Saturday...with 
showers lingering into sun. 33 


&& 


Hydrology...a Flood Watch remains in effect for the rivers flowing 
off the Olympics and the Cascades from Lewis to Snohomish counties. 
The Flood Watch was cancelled for Whatcom and Skagit counties as 
precipitation amounts are not high enough to force river flooding. 


Models show an additional 1 to 3 inches of precipitation tonight through 
Sun afternoon in the Olympics and Cascades...mainly from Lewis to 
Snohomish counties. A bullseye of 5 inches is possible over Montana 
Rainier. This amount of rain is great enough to cause flooding on 
some of the rivers flowing off the Olympics and Cascades. 


Any flooding would likely begin as early as late this afternoon or 
evening on the Skokomish River. The Cascade rivers could flood 
tonight or Sunday. Models show heavy rain ending Sunday night. 


&& 


Aviation...strong westerly flow aloft will continue tonight and 
Sunday. At the surface strong onshore flow will develop tonight. The 
air mass will remain moist and stable. By Sunday afternoon the 
frontal system over the area will weaken and surface high pressure will 
build Sunday night. 


Ceilings are generally MVFR. Low end MVFR visibility restrictions in 
rain are widespread. The mountains and foothills will be obscured 
tonight. Some IFR conditions are likely overnight. Improvement is 
likely Sunday afternoon. 


Ksea...rain will continue with MVFR conditions. Southwest wind will 
increase to 12g22kt this evening and continue overnight. Chb 


&& 


Marine...a strong system will continue moving through western 
Washington tonight. Gale southeast winds have already switched to 
southwest over the coast. The switch will occur over the inland 
waters this evening. The Strait and northern inland waters will have 
gales while Admiralty Inlet and Puget Sound sound will have Small Craft 
Advisory strength winds. 


Swells have subsided below 15 feet on the coast so both the high 
surf advisory and the coastal Flood Advisory have ended. 


Sunday should be a postfrontal day with onshore flow easing Sunday 
night and Monday. A ridge of high pressure will build over the area on 
Monday. A weaker system will arrive around Tuesday. Chb 


&& 


Sew watches/warnings/advisories... 


Washington...Flood Watch in effect for portions of western Washington. 
Winter Weather Advisory Cascades until 4 PM this afternoon. 


Pz...Gale Warning coast...Strait...northern inland waters. 
Small Craft Advisory Admiralty Inlet and Puget Sound sound and Hood 
Canal.
