NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
900 PM PDT Wednesday Jul 29 2015 


Synopsis...a strong upper level ridge will be over the Pacific 
northwest through the weekend. The ridge will weaken Sunday and 
Monday. An upper level trough will move over the area by the middle 
of next week. 




&& 


Short term...a strong upper ridge is over the region. Heights and 
thickness should peak late Friday afternoon...the 850mb temperature peaks 
around +20c...and maximum temperatures over the interior of western Washington should be in 
the lower to middle 90s from the Seattle metropolitan area south. The forecast 
for the coast is for highs in the 70s. Skies will be clear until later 
Saturday when some high clouds will arrive and highs will likely 
fall off a few degrees. 


Long term...as the ridge gives way to falling heights and onshore 
flow and marine air move back into the area...temperatures will cool Monday 
and Tuesday of next week. The 18z GFS shows an upper trough digging over 
the region by the middle of next week and if this solution pans out 
there will be cool temperatures and a good chance of showers Wednesday and Thursday of 
of next week. 


&& 


Aviation...an upper ridge will remain over the region. Continued westerly 
flow aloft. Low level northwest flow will become northerly late tonight. VFR 
conditions are expected across much of the area. There will likely 
be patchy IFR ceilings/visibilities on the coast after 0800 UTC. 


Ksea...VFR. Winds will remain northerly. 


&& 


Marine... high pressure offshore with lower pressure east of the Cascades will 
result in onshore or northwest flow through Friday. There are 
borderline Small Craft Advisory winds in the central and eastern 
Strait this evening. The flow will become briefly northerly or 
offshore early Thursday and Friday mornings due to a thermally induced area 
of low pressure trying to set up along the Washington coast. 


Onshore flow will strengthen this weekend...and this will result in 
the possibility of gale force winds over parts of the Strait of Juan 
Delaware fuca on Sunday. The flow will strengthen further on Monday... 
leading to an increased threat of gale force winds over parts of the 
Strait of Juan Delaware fuca. 


&& 


Fire weather... a very dry air mass aloft is settling over western 
Washington through Friday night. 850-700 mb layer average relative 
humidity will be running as low 10 percent between now and then. Middle- 
level Haines index will be solid 5 with values reaching 6 at times 
over the central Cascades...indicating a dry and unstable middle-level 
air mass. Will easily reach criteria for the dry and unstable 
category of red flag warnings through Friday evening. As a result... 
a red flag warning will soon be in effect. It will be targeted to 
locations above 2000 feet elevation...which will stick up above the 
inhibiting effect of low-level subsidence inversions. With such a 
dry air mass...leftover fuel moisture from recent rains will quickly 
become a memory. Over the mountain zones...this kind of air mass 
supports active fire behavior and rapid growth on existing fires. 
Haner 


&& 


Sew watches/warnings/advisories... Washington...heat advisory in effect 
from noon Thursday until 9 PM Saturday for parts of the Puget Sound sound 
region and southwest interior. 


Red flag warning in effect until 10 PM PDT Friday for the north 
and central Cascades and parts of the Olympic Mountains. 


Pz...small craft remains in advisory until 11 PM tonight for the 
coastal waters from James Island to Cape Shoalwater out to 10 
nm.
