NWS Forecaster Discussion




Area forecast discussion...corrected typo 3rd paragraph 
National Weather Service Seattle Washington 
230 am PDT Wednesday Sep 17 2014 


Synopsis...a large upper level trough offshore approaching western 
Washington will bring a chance of showers today. Showers will become 
likely tonight and Thursday morning as the trough moves slowly 
across the area. A smaller weaker upper level trough will prolong 
the chance of showers through Friday night. A strong upper level 
ridge will build over the region this weekend bringing sunny skies 
and warm weather. A weak front may reach the area around Tuesday. 


&& 


Short term...the large upper level trough offshore along 135w this 
morning will bring a showery pattern to West Washington today through Thursday. 
Infrared imagery shows a disorganized looking large blob of moisture 
embedded in the S flow aloft on the east side of the trough...all 
headed in the general direction of the pacnw. Disorganized areas of 
moisture are already bringing spotty light showers to West Washington this 
morning. A bit more organized band was west of the central/S Oregon 
coast at 09z/2 am and should reach West Washington this afternoon and this 
evening. Much of the moisture moving north will initially end up west of 
the coast...but will end up moving across West Washington late tonight and 
Thursday morning as the whole upper level trough shifts inland. The 
wettest period still looks to be tonight and Thursday morning as the 
trough axis crosses the area. Likely probability of precipitation look good for the coast 
and north interior with high end chance probability of precipitation around the Puget Sound sound 
region. 


The upper level trough will be over East Washington Thursday afternoon...but a 
surface ridge building along the coast may bring enough onshore flow 
for a Puget Sound sound convergence zone to form. However mesoscale models 
do not offer a strong case for a convergence zone at this point. 


West flow aloft over the NE Pacific behind the trough will drive 
another upper level shortwave trough across the area Thursday night 
and Friday morning for a continuing chance of showers. The 00z 
models have trended a bit stronger with this wave. The chance of 
showers has been kept through Friday night...although they could 
taper off by Friday evening. Kam 


Long term...GFS and European model (ecmwf) remain in good agreement in building a 
strong upper level ridge over the area this weekend. 500 mb heights 
climb back to around 5850 meters Saturday. NE low level offshore 
flow develops on Saturday as a thermally induced surface trough 
forms along the Oregon coast. Easterly flow will develop Saturday 
night as the surface trough extends north along the Washington coast. Maximum 
temperatures should easily climb back into the lower to middle 80s on Sunday. 


The upper level ridge axis will shift east over Idaho on Sunday. This will 
allow a skinny weakening cold front to approach the coast on Monday. 
Earlier models held the front offshore until Tuesday...but the 00z 
runs have it just offshore on Monday. This front will not amount to 
much...but the system behind it may bring some rain by Tuesday or 
Wednesday. Kam 


&& 


Aviation...an upper trough will approach the pacnw today. There is 
SW flow aloft with considerable middle level moisture and scattered 
light showers. Gradients have become light and without onshore 
flow it is not likely that areas of low clouds will develop this 
morning but there might be patchy low clouds and fog on the coast 
this morning. 


Ksea...middle level clouds. Increasing and thickening with a few light 
showers. Light and variable wind. 


&& 


Marine...light pressure gradients today and Thursday as a fairly weak 
weather system moves through the region. Offshore flow will develop 
over the weekend. 


&& 


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