NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
900 am PDT Wednesday Jul 23 2014 


Synopsis...an upper low will produce widespread showers and 
isolated thunderstorms over western Washington through tonight as it 
moves inland from the offshore waters. Rainfall will be heavy at 
times...especially in the mountains and at the coast. Showers will 
taper off Thursday as the low moves northeast. High pressure will 
build Friday through early next week for sunny warm weather. 


&& 


Short term...a 5590 meter upper low is over the Washington offshore 
waters near 47n/128w resulting in moist and unstable...diffluent 
southerly flow aloft over western Washington. Showers and isolated 
thunderstorms developed overnight as expected and continue this 
morning. The thunderstorms started around 4 am this morning and have 
occurred mainly in a line from western Whatcom County 
south-southeast to the South Washington Cascades...but the line is 
wide enough to include Seattle and much of the Puget Sound sound region. 
More than a half inch of rain has already fallen in some areas -- 
mainly the lower Chehalis valley and over the north Cascades. 


The upper low will track eastward toward the coast today...then move 
inland this evening and lift northeast into southern British 
Columbia late tonight. Widespread showers will continue through 
tonight...with 24-hour precipitation amounts of 0.5 to 1.0 inch over 
most of the western Washington lowlands and 1 to 2 inch amounts 
common over the mountains. As the climate section below notes...this 
will be one of the wettest July days in Seattle weather records. The 
snow level is around 10000 feet this morning and it will fall to 
around 8000 feet tonight. 


The line of thunderstorms mentioned above will move north-northeast 
out of the forecast area during the next few hours...and the 
lighting that occurs in the meantime will be mainly in the Cascades. 
There is no convection developing upstream yet...and there should be 
a short-term lull in thunderstorm activity. However conditions will 
become more favorable yet for thunderstorms this afternoon and 
evening...with the air mass becoming more unstable...increasing 
diffluence aloft... and a small jet just to our southeast as it 
rounds the base of the upper low. 


The flow aloft will veer to westerly again Thursday as the upper low 
tracks into southern Alberta. The air mass will stabilize and begin 
to dry...but moist onshore low level flow will continue and a Puget Sound 
sound convergence zone will probably develop. On the whole showers 
will decrease Thursday...with some sunbreaks likely over The 
Lowlands. 


Westerly flow aloft will continue over the forecast area Thursday 
night and Friday...but upper heights will start to rise as a ridge 
builds northward along the Rocky Mountains from The Four Corners 
high. There will likely be some marine layer clouds to start the 
day...but they will give way to mostly sunny skies at least over the 
interior. Mcdonnal 


Long term...here is the long term section from the early morning 
forecast discussion -- upper level high pressure amplifies over the 
northern rockies and interior Pacific northwest. Models show rising heights over western 
Washington through the weekend but the ridge axis remains far enough inland 
to prevent any strong offshore flow from developing. Instead...it 
looks like a nice gradual warm up to the 80s. Some models such as 
the European model (ecmwf) indicate the ridge could expand far enough west to induce 
a thermal low over western Washington and even warmer temperatures. This is 
rather uncertain this far out but above average temperatures appear 
likely with dry conditions. Mercer 


&& 


Climate...there have been 23 July days with 0.50 inches of rain or 
more since records started at sea-tac in 1945. Only 3 of those days 
have been since 2000...0.65 inches on July 16th 2001....0.60 inches 
on July 20th 2012 and 0.58 inches on July 7th 2002. The record for 
the wettest July day at sea-tac is 0.85 inches on July 13th 1981. 
The wettest July day on record in Seattle is 0.98 inches on July 5th 
1897 when records were kept at the federal building downtown. Felton 


&& 


Aviation...upper level low about 150 nm west of khqm at 18z will 
move east today then northeast tonight. Strong southerly flow aloft 
today becoming light tonight...then strong northwest late. Air mass 
unstable and moist all levels. 


Satellite imagery shows a solid mass of clouds over western 
Washington. Metars shows multiple cloud levels and various 
visibilities in showers. Thunderstorms are confined to the eastern 
sections mainly near the Cascades but are possible elsewhere. Some 
improvement tonight as the low moves overhead. The low will move off 
to the northeast early Thursday morning but wrap around moisture 
will prevent ceilings from improving much until Thursday afternoon. 


Ksea...variable ceilings 1000-3000 feet late morning and early 
afternoon in showers. Thunderstorms possible today. Some improvement 
in the ceilings tonight. Light winds this morning becoming southerly 
10-15 knots this afternoon into the evening hours. Chb 


&& 


Marine...models show a surface trough off the coast this morning 
weakening and moving inland tonight. It should still have enough 
punch to bring moderate onshore flow this evening resulting in Small 
Craft Advisory southwest or west winds in several zones including 
Puget Sound sound. Onshore flow becomes stronger Thursday. For now have 
indicated 20-30 knots westerlies in the Strait but gales seem possible 
there on Thursday. 


After Thursday the normal Summer pattern returns with onshore flow 
strong enough for Small Craft Advisory westerlies in the Strait each 
afternoon and evening. Chb 


&& 


Sew watches/warnings/advisories... 
Washington...none. 
Pz...Small Craft Advisory outer coast...central and east Strait... 
northern inland waters....Puget Sound and Hood Canal... 
Admiralty Inlet.
