NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
930 am PDT Tuesday Aug 4 2015 


Synopsis...a low pressure system aloft will remain over the 
region through Wednesday. Look for weak high pressure to prevail 
over the area Thursday and Friday. 


&& 


Short term... 
an upper level trough with a low center over British Columbia will 
continue to dig south during the day...resulting in lowering 500 mb 
heights over the County Warning Area. The height falls coupled with moderately 
strong onshore flow will result in even additional cooling today... 
especially across the interior. 


Models show more southwesterly onshore gradients later tonight/Wednesday 
morning which would be better for brining more solid low clouds into 
the interior. Will stick with the mostly cloudy start to the 
day...with partly sunny skies again in the afternoon. The trough 
axis will be over the area with 500 mb heights down near 5700m so 
Wednesday may end up the coolest day of the week. There could also 
be some patchy morning drizzle on the coast. Models show a secondary 
trough axis digging southward across western Washington during the afternoon so will 
maintain a threat of showers...though quantitative precipitation forecast amounts should remain 
light. Showers may linger into the evening as the trough pulls east and 
the flow becomes more northwesterly. There could even be a brief convergence 
zone over central/north Puget Sound sound. 


500 mb heights rebound on Thursday as the low pulls east and a ridge 
offshore moves toward the area. Low level northwesterly onshore flow will 
prevail but weaken during the day. The trend should be toward 
slightly warmer temperatures...reaching the middle 70s to lower 80s 
around Puget Sound sound and the SW interior. Mercer/05 


Long term from the previous discussion... 
virtually all the models show the transitory ridge shifting eastward 
Thursday night and Friday. An upper low will approach with lower 
heights by later in the day. The main onshore influence will not 
be felt until the weekend so another partly to mostly sunny day 
appears likely. Highs should reach slightly above average...into 
the low 80s around Puget Sound sound and the SW interior...cooler near 
the water and toward the north interior/coast/Strait. 


Long range models disagree on the timing...strength...and track of 
the upper low for the weekend. The general idea is that upper 
heights will trend lower and onshore flow will increase once again. 
This should introduce more clouds and a threat of showers to western Washington. 
Made little change to the extended which has a chance of showers 
indicated at times. This can be fine tuned once the 
GFS/ECMWF/Canadian come into closer agreement. Temperatures will 
probably cool back to near average or even slightly below. Mercer 


&& 


Aviation...an upper level low is spinning over b.C. With westerly 
flow aloft over western Washington. Marine stratus pushed inland this 
morning with scattered-broken ceilings near 1000 feet. The stratus in the interior 
will lift and scatter this afternoon. The upper low will shift south 
into western Washington tonight for a chance of showers...mainly near the 
Canadian border. Stratus will return for MVFR to IFR conditions Wednesday 
morning. 33 


Ksea...bkn-ovc011 this morning then lifting and scattering this 
afternoon for VFR conditions. Surface winds will remain southerly. 33 


&& 


Marine...high pressure over the the NE Pacific will maintain moderate to 
strong onshore flow across western Washington this week. Westerly gales are 
forecast through the central/east Strait tonight. A weak cold front 
will cross through the region Friday night into Saturday. A 1011 mb 
low will spin offshore this weekend. 33 


&& 


Sew watches/warnings/advisories... 
Washington...none. 
Pz...Gale Warning in effect from 5 PM this afternoon until 5 am 
Wednesday for the central and eastern Strait of Juan Delaware fuca. 


Small craft advisories are in effect for the coastal waters 
from Cape Flattery to Cape Shoalwater 10 to 60 nm and the 
Admiralty Inlet.
