NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
300 PM PDT Wednesday Sep 17 2014 


Synopsis...an upper level trough will produce showers as it moves 
across the region through Thursday. A trailing weak upper level 
trough will prolong the chance of showers through Friday night. A 
strong ridge will build over the region this weekend bringing sunny 
skies and warmer weather. Another weak trough will traverse the area 
late Monday into Tuesday...followed by a stronger system on 
Wednesday. 


&& 


Short term...infrared satellite imagery shows a rather disorganized mass 
of middle/high based clouds streaming northward into the region. The upper 
low which has fed moisture into the area is becoming cut off but a 
portion of this system will get pulled into western Washington tonight. Various 
model time-heights show the lower levels slowly becoming saturated 
later tonight. A northern stream trough will provide increasing lift with 
measurable rainfall likely across most the area. 


The 500 mb trough axis shifts eastward by Thursday afternoon. Moist westerly 
flow will still produce showers in the mountains. The best chance of 
showers across The Lowlands will be early on...then decreasing 
during the afternoon. Some mesoscale models and even the gfs40 imply a 
convergence zone may develop late in the afternoon into the evening. 
The surface ridge west of Puget Sound sound supports this idea with the flow 
favoring the north Seattle to Everett corridor. Gradients weaken late 
Thursday night and any convergence zone activity should diminish. 


Another weak trailing upper trough and associated front will 
dissipate as it reaches western Washington Friday. There may still be enough 
moisture for some showers...especially coast and mountains in the 
morning. The flow turns more northwesterly Friday afternoon as upper heights 
start to build. Partial sunshine is expected later in the day with 
slightly warmer temperatures. 


The warming trend continues into Saturday as high pressure rapidly 
amplifies over the Pacific northwest. Thermally induced low pressure will be 
near the coast so offshore flow will dry out the air mass and allow 
for a warming trend. Some areas away from the water may reach the 
low 80s. 


Long term...the warming trend continues into Sunday with the ridge 
and offshore flow still in place. MOS guidance seems too cool in 
this pattern and may be heavily influenced by climatology. Building 
upper heights and stronger offshore flow should result in at least a 
few degrees warming. High temperatures are trended above MOS...with 
widespread middle 80s over the interior. 


High pressure aloft begins to shift inland Sunday night and Monday. 
Thermally induced low pressure over the interior of western Washington will 
shift eastward...ushering in onshore flow Monday. Temperatures will trend 
cooler on Monday and more so on Tuesday as a weak system arrives. 
This initial trough will fall apart as it encounters the ridge but 
there may be enough moisture for some showers. 


Long range models are in surprisingly good agreement on the 
westerlies arriving by middle week. This pattern change should usher in 
wetter and cool conditions just in time for the first week of fall. 
Some models indicate it could be rather breezy as well. Mercer 


&& 


Aviation...an upper level trough is digging offshore this 
afternoon...sending middle/high level moisture into western Washington. The 
flow aloft is southerly with diffluent flow and weak lift over the 
region. Radar shows mainly light showers across western Washington with VFR 
conditions expected. Showers will increase tonight through Thursday 
morning as the upper level trough shifts inland. 33 


Ksea...showers will increase in coverage tonight 06-12z as an upper 
level trough shifts inland. Light northerly winds will switch to southerly 
06-09z. 33 


&& 


Marine...a 998 mb low is spinning off the northern California coast this 
afternoon. This low will weaken as it moves east and inland on 
Thursday. Pressure gradients and winds will remain light across 
western Washington...except west winds rising to 15 to 25 knots through the 
Strait of Juan Delaware fuca Thursday evening. A weak cold front will cross the 
area on Friday with onshore flow expected. Offshore flow will 
develop on Saturday as an inverted surface trough forms along the 
coast. This inverted surface trough will weaken on sun. A surface 
trough will then cross the coastal waters on Monday. Models show a 
stronger system developing over the NE Pacific midweek...however exact 
strength and timing is still unclear. 33 


&& 


Sew watches/warnings/advisories... 
Washington...none. 
Pz...none.
