NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
920 am PDT Thursday Jul 31 2014 


Synopsis...a strong upper level ridge over the Pacific northwest 
will bring warm sunny days to western Washington through much of the 
next week. Weak onshore flow will result in some night and morning 
low clouds...especially beyond Thursday. Weak instability aloft 
Friday through Sunday could result in isolated afternoon and evening 
thunderstorms...mainly over the mountains. 


&& 


Short term...visible satellite imagery shows mostly clear skies 
across western Washington this morning including most of the coast. A dry and 
warming air mass resides under a 5880m upper ridge. 24 temperature 
changes across the interior are averaging around +5c over yesterday 
with light gradients...thus many locations will see potential highs 
reached. MOS has come up a few degrees so the forecast looks pretty 
good with middle to upper 80s around Puget Sound sound. A couple spots inland 
from the waters and the SW interior could push 90 today. 


Stratus is expected to reform along the coast this evening but only 
seep partially inland overnight with generally light pressure 
gradients. Low clouds could reach Shelton and also down the Strait 
but the Puget Sound sound area should start off void of any low clouds. 
However...there will be increasing moisture in the middle and upper 
levels tonight into Friday which adds an interesting Twist to the 
forecast. 


Most of the 06/12z models this morning are still advertising 
convection over the mountains Friday afternoon and evening. Lifted indice's are 
negative and the air mass very warm and unstable. There is another 
element to consider for late tonight/Friday morning...that being 
elevated convection over The Lowlands and especially toward the 
coast. Models do not show quantitative precipitation forecast which would be expected with elevated 
convection since it is usually virga that falls...precipitation not 
reaching the ground. Latest models agree that an upper level trough 
and associated vorticity maximum feature will increase vertical lift in the 
middle levels early Friday morning. The 700 mb flow turns southerly and the 
air mass moistens in the 700-500 mb layer with increasing Theta-E. 
This is a key signature for elevated convection but it is highly 
uncertain if there is enough lift through a deep enough layer for 
elevated thunderstorms. Will need to look over models closer this 
afternoon and consider that possibility. Even if we do get some 
elevated thunderstorms over The Lowlands...measurable rain is 
unlikely and lightning would primarily be intra-cloud but that is 
not a certainty. The threat of thunderstorms across western Washington decreases 
later Friday evening as the upper trough lifts north of the area and we 
lose daytime heating. 


Another larger trough will lift northward off the Washington coast on Saturday. 
The lower heights usually means a deeper marine layer so low clouds 
are likely to spread inland across most The Lowlands early. Low 
clouds will burn off by afternoon but the added humidity will hinder 
potential high temperatures. The current forecast is for low 80s 
around the sound Saturday afternoon which looks good. The top of the 
marine layer should remain below the Cascade crest so surface based 
instability coupled with southerly flow should trigger some thunderstorms 
once again. Convection should train northward along the Cascades with 
little threat to The Lowlands at this point. For the sea-fair 
activities Saturday and Sunday the weather looks dry as detailed 
below. Mercer 




Long term...from previous 330 am discussion...Sunday looks about 
the same as Saturday over The Lowlands. Onshore flow will allow 
morning stratus to form over most inland areas...followed by a 
midday burn-off. Maximum temperatures will remain in the middle 70s to middle 80s 
inland. The upper level shortwave trough will shift over East Washington/southeast 
b.C. With westerly 700 mb flow developing over West Washington. This should end 
the potential for convection over the mountains on Sunday. However I 
will hold on to a chance of Cascade thunderstorms for Sunday 
afternoon and evening a little longer just in case. 


A weaker upper level ridge will remain over the Pacific northwest on 
Monday...then both the GFS/European model (ecmwf) have the remnant of a weak front 
reaching West Washington late Tuesday and early Wednesday. This looks like a 
dry feature so the main effect will probably be continuing weak to 
moderate onshore flow. 500 mb heights remain around 5860 meters so 
maximum temperatures should remain in the 70s and 80s. Kam 


&& 


Aviation...an upper ridge centered over Nevada with a trough along 
145w will give south to southwest flow aloft to the area through 
Friday. At this surface...a ridge of high pressure over the offshore 
waters along 132w combined with a thermally induced low over 
southeast Washington will give light low level onshore flow. Skies 
across western Washington are nearly clear with only one small patch 
of fog seen from about kuil northward on the North Washington coast 
and in the Strait of Juan Delaware fuca. This fog patch will dissipate 
early this afternoon. Expect mainly clear conditions through 
tonight. The air mass is dry and stable. 


Expect a shallow push of marine air onto the coast...in through the 
Chehalis gap...and through the Strait of Juan Delaware fuca early Friday 
morning. Fog and stratus is not expected to reach the interior of 
western Washington except around Whidbey Island and Shelton. Where 
the fog and stratus moves in Friday morning...expect a period of low 
IFR conditions. Albrecht 


Ksea...only a few cirrus through Friday morning. Expect north to NE 
winds 5-7 knots this morning to become more northwesterly after 20z...then 
return to the NE after 04z this evening. Albrecht 


&& 


Marine...high pressure over the offshore waters combined with 
thermally induced low pressure east of the Cascades will result in 
light onshore flow through Friday. The onshore flow will increase 
somewhat late this afternoon and tonight due to heating in the 
interior...this increase in onshore flow is expected to produce 
Small Craft Advisory conditions over the central Strait of Juan Delaware 
fuca and the East Entrance...and in the near shore coastal waters 
from about James Island southward. 


A weak disturbance aloft will move across the area late Friday 
afternoon and Friday evening. This disturbance has a slight chance 
of producing some isolated lightning strikes over the inland waters 
as it passes. The disturbance will also help increase onshore 
pressure gradients somewhat and a brief period of gale force winds 
are possible Friday evening in the central and east Strait. A gale 
watch may be issued for Friday night if the GFS and European model (ecmwf) model 
solutions support the stronger gradients in their late morning 
updates. 


The overall pattern is not expected to change much Saturday through 
early next week with diurnal inflow through the Strait and northwesterly 
winds over the coastal waters. These areas could see Small Craft 
Advisory conditions during the late afternoon and overnight 
hours and possible gales on some days in the central and eastern 
Strait of Juan Delaware fuca. Albrecht 


&& 


Sew watches/warnings/advisories... 
Washington...none. 
Pz...Small Craft Advisory central Strait of Juan Delaware fuca... 
East Entrance to the Strait of Juan Delaware fuca...and 
coastal waters from James Island to Cape Shoalwater out 
to 10 nm.
