NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
350 am PDT Sat Aug 1 2015 


Synopsis...an upper ridge will gradually weaken over the next 
couple of days. Onshore flow will return early next week for 
cooler weather. An upper trough will bring a chance of showers 
later in the week. 


&& 


Short term...satellite imagery shows low clouds along the coast 
with clear skies over the remainder of the area at 3 am. With the 
clear skies over most of the area temperatures were in a wide range 
at 3 am...lower 50s to lower 70s. 


Upper level ridge remaining over the area today resulting in another 
hot day for the interior. Surface gradients are flat and 
temperatures aloft are similar to friday's readings. Temperature 
guidance is going for a few degrees of cooling today but with little 
change in the pattern will go more along the lines of persistence 
for highs today with the warmest locations once again in the middle to 
upper 90s and the cool spot being the coast with 70s and lower 80s. 


Some small changes begin to take place tonight into Sunday. The 
upper level ridge begins to weaken and shift east. By 00z Monday the 
thermally induced surface trough is over eastern Washington. This 
will induce some low level onshore flow in western Washington Sunday 
afternoon. Temperatures aloft cool slightly...850 mb temperatures 
lowering from near plus 20c to near plus 18c. The combination of 
these two variables will be slightly lower maximum temperatures on 
Sunday...but still plenty warm with lower 90s from Seattle 
southward. 80s will be common north of Seattle with 70s along the 
coast. Even with the slightly cooler temperatures the heat advisory 
will remain up through Sunday evening for the Seattle 
area...southwest interior and east Puget Sound sound lowlands. 


With the upper level ridge axis and thermally induced surface trough 
east of the area Sunday night a marine push will develop over 
western Washington. Model onshore gradients are not very impressive 
and indicating more of a weak push into Monday. Temperatures aloft 
continue to cool...850 mb temperatures down around plus 14 or 15c by 
00z Tuesday...as a weak upper level trough moves into the area. 
Model cross sections also show the winds right off the ground up 
through 700 mb remaining northwesterly Sunday night into Monday. 
This also supports the weak push scenario. In general will go for 5 
to 10 degrees of cooling on Monday versus sundays maximum temperature 
readings. This will put maximum temperatures in the interior mostly in 
the 70s to lower 80s. With 60s and lower 70s along the coast. 


More significant cooling on Monday with the upper level ridge axis 
and thermally induced thermal surface trough to the east. Trough is 
two variables will re 


Long term...if you are not a fan of the hot weather we have been 
experiencing the last few days then you will like the extended 
forecast. While there is not a lot of consistency in the models the 
general idea of cooler weather is evident in all of the extended 
solutions. The European model (ecmwf) is the more optimistic of the models with 
northwesterly flow aloft over the area until a weak ridge builds 
late in the week. The GFS and Canadian bring an upper level low down 
from the northwest and move the low into southern British 
Columbia/western Washington Thursday with the Canadian model about 
12 hours slower with this feature versus the GFS. The Canadian keeps 
some weak trofiness over the area Friday while the GFS does show 
some weak ridge by later Friday into Saturday. Even through it is 
the climatologically driest time of the year with the lack of 
consensus in the models will stay with the current forecast that has 
a chance of showers forecast for most of the area Thursday and 
Friday with high temperatures near or a little below normal...in the 
70s for the interior and 60s for the coast. Felton 


&& 


Climate...July ended up being the warmest month on record in 
Seattle with an average temperature of 71.2 degrees. The old record 
was 71.1 degrees set in August of 1967. This record includes the 
federal building records which go back to the 1890's. 


It was the warmest July on record at both Hoquiam and Forks. At 
Hoquiam the average temperature for July was 63.9 degrees breaking 
the record of 63.0 degrees set in 1958. At Forks the average 
temperature was 63.0 degrees breaking the record of 61.4 set in 
1990. Records began in Hoquiam in 1953 and at Forks in 1966. 


Other locations around western Washington...at Bellingham it was the 
2nd warmest July on record with an average temperature of 67.2. The 
record is 68.0 degrees set in 1958. Olympia also had the second 
warmest July on record with an average temperature of 68.0 degrees. 
The record is 69.1 set also in 1958. 


&& 


Aviation...a broad upper level ridge will remain over the Pacific 
northwest through this weekend with light west-SW flow aloft. Except 
for areas of late night and morning stratus...the air mass will 
remain dry...stable and very warm. The density altitude will be 
higher than normal during the afternoon hours. 


Areas of IFR stratus have formed along the coast...over the western 
Strait of Juan Delaware fuca and between khqm and kshn. The stratus should 
burn off again by 18z this. Otherwise clear skies will continue 
across West Washington. 


Ksea...clear skies for good VFR conditions. Surface winds will 
remain north 3-7 knots this morning then rise to north-northwest 5-10 knots after 18z 
Saturday. Kam 


&& 


Marine...a large surface ridge offshore will combine with lower 
pressure over East Washington to maintain varying degrees of onshore flow 
through next week. The onshore flow is expected to be mainly 
moderate during the late afternoon and evening hours this 
weekend...but strong flow with possible gales in the Strait of Juan 
Delaware fuca is possible. 


Earlier models suggested gales in the central and east Strait this 
evening...but the 00z GFS has backed off on the uil-bli pressure 
gradient. None of the U.S. Mesoscale models are close to gale force 
winds...and both the 18z and 00z 2.5km Canadian lam model only 
showed a tiny area of 30-35 knots winds for just one hour. As a result 
I have converted the gale watch to a high end Small Craft Advisory for late this 
afternoon and tonight. A Small Craft Advisory will also continue over the outer 
coastal waters for borderline Small Craft Advisory northwest winds a times. This northwest flow on 
the coast is expected to spread over the inner coastal waters along 
the central coast this evening. Kam 


&& 


Fire weather...previous discussion...a critical period for fire 
weather continues over all of western Washington...with a very dry 
air mass in place. The immediate coast has seen some relief this 
afternoon from sea breezes which have raised dewpoints into the 
upper 50s at Hoquiam and Quillayute. Elsewhere across western 
Washington...dry air persists. 


In addition...elevated mountain locations are feeling the added 
effect of somewhat unstable middle-level air...with both middle-level and 
high-level Haines 5 conditions continuing through Saturday evening. 
Visible satellite imagery showed a burst of smoke this afternoon 
coming from the Paradise fire...so it appears the fire is feeling 
the effects of the dry and unstable air mass. Will keep the red flag 
warning going for elevations above 2000 feet until Saturday evening 
for the dry and unstable air mas. Large fire growth in western 
Washington historically takes place under such conditions. Haner 


&& 


Sew watches/warnings/advisories... 
Washington...heat advisory remains in effect until 8 PM Sunday for parts of 
the Puget Sound sound region and southwest interior. 


Red flag warning in effect until 10 PM Saturday night for the 
Cascades and Olympics above 2000 feet. 


Pz...Small Craft Advisory outer coastal waters and central and east 
Strait of Juan Delaware fuca.
