NWS Forecaster Discussion




Area forecast discussion...corrected 
National Weather Service Seattle Washington 
900 PM PDT Thursday Oct 30 2014 


Corrected remarks about Skokomish River in hydrology section 


Synopsis...a Pacific frontal system will bring rainfall to western 
Washington tonight. The cold front will cross the Cascades early 
Friday morning...and rain will turn to showers and decrease. 
Saturday should be partly sunny with light spotty showers. A weak 
front will probably bring some light rain on Sunday. Rainy and 
locally windy weather is likely most of next week. 


&& 


Short term...a Pacific frontal system is moving slowly through the 
Pacific northwest this evening...with areas of rain continuing 
across western Washington. Precipitation amounts for the storm so 
far have been roughly 0.50 to 1.50 inches for the coast and 
mountains...with locally almost 3 inches over the Olympics. Up to 
0.75 inch has fallen in the interior lowlands. The snow level is 
still around 7500 feet. 


The system will progress slowly eastward with the cold front 
crossing the Cascades late tonight or early Friday morning. Steady 
rain will turn to showers...which will probably taper off quickly on 
Friday afternoon. 


An upper trough will move to the coast late Friday night and inland 
Saturday. However the portion of the trough that moves into western 
Washington will be weak and disorganized...with the core of the 
upper trough digging southeast across California. A forecast of 
partly sunny skies and a chance of showers looks good. For the 
showers that do occur...precipitation amounts will be light and 
coverage might just be scattered. The snow level will be around 4500 
to 5500 feet. 


A small flat upper ridge will move into the Pacific northwest 
Saturday night and Sunday...with a weak warm front following closely 
behind the ridge axis. Models are having difficulty with the timing 
of this system. It will bring some rain to western Washington on 
Sunday...but some model runs show slower timing with the rain moving 
in Sunday night. Mcdonnal 


Long term...here is the long term section from the afternoon 
forecast discussion -- confidence in this period was not high due to 
continued disagreement and lack continuity in the medium range 
solutions. It did appear that western Washington will probably receive 
significant rainfall during this period. The medium range solutions 
seemed to be converging on the idea of a significant rainfall 
producer impacting the County Warning Area during the Monday/Tuesday time frame. Have kept 
probability of precipitation above climatology during the extended period. 


&& 


Hydrology...about 1 to 2.75 inches of rain has fallen over the 
Olympic Mountains...with the heaviest amounts along the southeast 
slopes. Radar and satellite imagery show the back edge of the 
heaviest rainfall moving east of the Olympics though...and models 
show only another 0.3 to 0.6 inch of rain in the skokomish basin 
through Friday. The Skokomish River near Potlatch is rising...and 
actually tracking slightly ahead of the forecast. After much 
deliberation I will go ahead and issue a Flood Warning this 
evening...but confidence is not especially high. It could fall just 
short of flood stage. 


The other river we have been concerned about is the Nooksack 
river...because the other focus of heavy rainfall is around Mount 
Baker. Flooding on the Nooksack looks unlikely though. 


Flooding is not expected on other area rivers during the next 7 
days. Mcdonnal 


&& 


Aviation...SW flow aloft. The air mass is stable and moist... 
becoming more unstable Friday as cooler air moves in aloft. The 
heaviest rain with this frontal system at 8pm was mainly east of I-5 
and moving into the Cascades. The radar shows precipitation should become 
more showery tonight and Friday. 


Ksea...a band of heavy rain moved through the metropolitan area this 
evening and now the radar suggests the precipitation will be more showery. 
The infrared satellite image still shows a frontal band draped over 
the area...so showers could turn back to rain again but certainly on 
Friday the cooler more unstable air will work in over the area for 
just scattered showers. 


&& 


Marine...looks like a front went through the area with westerlies 
in the Strait this evening...Race Rocks has been up around 30kts for 
a few hours...the buoys and Smith Island in the Strait have not 
shown much of the westerly push...but with race blowing pretty 
strong I have a Small Craft Advisory up for the whole Strait for 
this evening. Another breezy spot at 8pm was the area north of 
Bellingham...and Sandy Point had gusts to 28mph...but the winds over 
the water and throughout the San Juans were not more than about 
10kts so I don't have an Small Craft Advisory for the northern waters. The winds over the 
coastal waters behind this front should turn to northwest 15kt 
tonight...but then become more SW again Friday as a surface low 
pressure trough moves through the coastal waters. Weak high pressure 
will build across western Washington Saturday. More active weather 
is on the way Sunday through early next week...with more frontal 
systems expected to move across the waters. 


&& 


Sew watches/warnings/advisories... 
Washington...Flood Watch in effect from 6 PM PDT this evening through 
late Friday night for Mason County. 


Pz...Small Craft Advisory Strait of Juan Delaware fuca until 11pm.
