NWS Forecaster Discussion




Area forecast discussion...corrected 
National Weather Service Seattle Washington 
920 am PDT Tuesday Sep 2 2014 


Corrected aviation and marine sections. 


Synopsis...a frontal system will bring a little rain to western 
Washington this afternoon and evening. High pressure will produce 
sunshine and warmer weather for the remainder of the week. 


&& 


Short term...a relatively vigorous and fast moving upper trough and 
cold front will bring a little rain to the area later today. Rain 
should reach the north coast late this morning and spread into the 
interior during the afternoon. Showers will become mostly confined 
to the Cascades and a Puget Sound sound convergence zone by early evening 
as the system quickly moves inland. A few showers will linger over 
the Cascades into Wednesday morning. Otherwise...Wednesday will be 
dry with decreasing clouds as drier northerly flow aloft develops. 


High pressure aloft will be in control Thursday and Friday with low 
level offshore flow developing. This will give sunny weather with 
highs warming 3-5 degrees each day. Highs in the 70s will be common 
Wednesday and parts of the south sound should see highs near 80 by 
Thursday. Schneider 


Long term...previous discussion...high pressure aloft over the NE 
Pacific will persist Friday and Saturday before possible changes in 
the pattern. Thermally induced low pressure will expand northward along 
the Washington coast during this period with dry offshore flow. Temperatures 
will warm in this pattern...with low 80s from the central sound to 
the SW interior. 


500 mb heights fall Saturday night...then a weak trough arrives 
Sunday. This should induce an onshore push bringing marine air 
inland and resulting in moderating daytime temperatures. This system 
will likely bring little if any precipitation so the main affect 
will be the change onshore flow conditions. Highs will only reach 
the 70s and possibly struggle out of the upper 60s near the coast. 


Weak onshore flow but mostly dry conditions should prevail early 
next week. The majority of models show a trough clipping the region 
but at this time does not appear to be a rain producer. Mercer 


&& 


Aviation...flow aloft today will remain westerly as an upper level 
trough approaches the area from the north...then become 
northwesterly late tonight as the trough moves into eastern Oregon. 
The associated cold front will bring rain to the coast and north 
interior this morning...then spreading showers into the interior 
during the afternoon. 


Ceilings over the area this morning remain generally MVFR over the 
interior...and VFR for the coast. Expect conditions to improve over 
the interior through midday as ceilings lift to VFR 
levels...conversely increasing low and middle level clouds will 
establish MVFR conditions for the coast through the same period. 
Onshore flow will persist through Wednesday with increasing 
southerly winds over the interior this afternoon and evening. Low 
level flow from the east Strait through the north Puget Sound sound area 
will become westerly to northwesterly this evening...with a possible 
Puget Sound sound convergence zone forming over King County. The trailing 
upper level trough will keep showers over the interior and Cascades 
behind the front tonight...generally winding down after midnight. 


Ksea...MVFR conditions will improve to VFR through midday. Light 
southerly winds will become established by 18z and strengthen 
through the afternoon to 8 to 10 knots. Expect showers in the vicinity 
this afternoon and evening with a possible pscz forming over north 
King County later this evening. 


&& 


Marine...onshore flow will increase behind a cold front this 
afternoon. Gale force winds are forecast through the central and 
east Strait of Juan Delaware fuca tonight. Onshore flow will ease late 
tonight. High pressure over the NE Pacific will maintain onshore flow 
through Wednesday. Northerly flow will prevail Thursday and Friday as low pressure 
forms along the coast. 33 


&& 


Sew watches/warnings/advisories... 
Washington...none. 
Pz...Gale Warning central and east Strait of Juan Delaware fuca. 
.Small Craft Advisory coastal waters...Western Strait... 
northern inland waters...and Admiralty Inlet.
