NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
920 am PDT Wednesday Jul 1 2015 


Synopsis...high pressure aloft will remain over the Pacific 
northwest into early next week for hot and dry weather. 


&& 


Short term...the broad upper level ridge over the Pacific northwest 
will build a little today as an upper level shortwave ridge moves 
through the top of the longwave ridge. GFS 500 mb heights rise to 
around 5900 meters over the Puget Sound sound region. Pressure gradients 
are actually weakly offshore this morning. The only stratus around 
this morning is over Grays Harbor...otherwise skies will remain 
cloud free today. With the full dose of sunshine today maximum 
temperatures over the interior from Seattle southward are expected 
to reach the upper 80s and lower 90s. The north interior...Strait...and 
coast will be a little cooler with highs in the 70s to middle 80s. 


Most of West Washington is expected to cool off into the 50s overnight...but 
relief will be less in the metropolitan corridor from Seattle to Tacoma and 
eastward across The Lowlands...where overnight lows should only drop 
off into the upper 50s to middle 60s. Onshore flow will be weak northwest 
tonight so no stratus or cooler marine air mass is expected to reach 
inland areas. 


Thursday is expected to be similar to today with the hottest areas 
once again reaching the upper 80s and lower 90s. A heat advisory 
will be issued for the areas that have both the hottest daytime 
temperatures today and Thursday and the warmest lows overnight. This 
would be the Seattle Bellevue Tacoma area as well as the east Puget Sound 
sound lowlands. The other hot areas of the interior are expected to 
cool off a bit more tonight. 


There is a weak upper level trough offshore near 45n/133w that 
should track east-northeast across northwest Washington Thursday morning. It does not look 
like this feature will have any impact on maximum temperatures Thursday...but 
it does look like it will increase the westerly onshore flow 
Thursday evening. 


For Friday...the GFS and European model (ecmwf) are in good agreement in slightly 
weakening the upper level ridge over the region...as an upper level 
low moves across far northern b.C. Combined with the somewhat 
stronger westerly onshore flow Thursday night...this should be 
enough to cool maximum temperatures 3-5 degrees...leaving maximum temperatures in the 80s. 
Kam 


Long term...the upper ridge over the area will retrograde offshore 
this weekend and early next week. Heights will initially remain high 
and models indicate a thermal trough developing along the coast for 
low level offshore flow. This could result in even warmer 
temperatures with lower to middle 90s possible by Sunday for parts of 
the interior. 


It looks like there will be some cooling early next week as low 
level onshore flow increases again and upper heights gradually lower 
across the region. Temperatures will still be a little above normal 
however and there is no precipitation expected through next 
Tuesday. Schneider 


&& 


Aviation...high pressure aloft over the Pacific northwest for the next couple 
days. A weak system will brush by to the north of Washington 
tonight. Light westerly flow aloft...becoming more northerly later 
tonight and Thursday. Weak low level onshore flow will continue. The 
air mass will remain dry except for a shallow surface-based marine 
layer. 


Patchy stratus along the South Washington coast will dissipate by 
midday. Marine stratus will reform along the coast tonight and 
Thursday morning. Otherwise...skies should be generally clear. 


Ksea...northerly wind 6-11 knots today...becoming north-northeast 4-7 
knots tonight. Dtm 


&& 


Marine...relatively weak onshore flow will continue through 
Friday...with high pressure well offshore and lower pressure east of 
the Cascades. The result should be Small Craft Advisory northwest 
winds over the outer coastal waters...and marginal Small Craft 
Advisory westerlies in the central and east Strait during the 
evening hours. 


A thermally induced trough of low pressure will develop over western 
Washington this weekend...and winds should be 20 knots or less. 
Dtm/mcdonnal 




&& 


Sew watches/warnings/advisories... 


Washington...none. 
Pz...Small Craft Advisory outer coastal waters...central and east 
Strait of Juan Delaware fuca.
