NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
146 am PDT Wednesday Jul 1 2015 


Synopsis...high pressure will dominate the weather the next several 
days. Marine stratus will keep the coastal temperatures in the 60s to 
low 70s...but hot weather will continue inland with afternoon 
temperatures reaching into the 90s. An upper low north of the area 
will flatten the upper ridge this weekend resulting in slight cooling 
for the beginning of the week. 


&& 


Short term...an upper ridge of high pressure will result in hot and 
dry weather this week. 500mb heights will rise to around 590 dams 
today with 850mb temperatures around 21 degree c...and hold through 
Thursday. This will result in inland temperatures peaking in the middle 
90s with local areas in the upper 90s to low 100s. The Heights will 
begin to lower Friday as an upper low over northwest Canada deepens and 
moves SW...and there will be slightly cooler temperatures for 
Friday. Since these temperatures are running around 15 degree f above 
the seasonal normals and my push into the upper 90s...decided to 
issue a heat advisory for most inland areas today through Friday 
evening. 


Marine stratus will be mostly confined to the immediate coast in the 
nights and mornings...keeping cooler temperatures for the coast and 
parts of the Coast Range. The stratus may move further up the coastal 
valleys and the lower Columbia River Thursday night...and may briefly 
move over the Vancouver and Portland metropolitan areas. These low clouds 
stratus will be shallow though and clear quickly...with only 
marginal cooling to the inland temperatures. 


Models are a bit on how much the Canadian low will impact The 
Heights...and temperatures over the area Saturday. The 500mb heights 
will lower and expect temperatures to cool some...but am uncertain of 
how much cooling there will be. With the current model runs expect 
the inland temperatures on Saturday to be 2 to 6 degree f cooler. Tj 


Long term...Saturday night through Tuesday...upper level ridge of 
high pressure will rebuild westward and maintain over the region 
through the weekend. This will maintain temperatures well above 
seasonal normals...namely in the low to middle 90s inland and near 70 
at the coast. Upper low pressure passes well to the north of the 
area over the weekend...but will flatten the ridge slightly and may 
increase onshore flow. This would bring increased marine stratus 
along the immediate coast and keep temperatures slightly cooler than 
currently indicated. Maintained a slight chance of afternoon/evening 
thunderstorms near the crest of the Cascades for Sunday with a 
fair amount of instability depicted by forecast models...especially 
in the Lane County Cascades. Models begin to diverge early next 
week...but likely remaining generally dry and warmer than normal. 
Cullen/tj 
&& 


Aviation...VFR clear for the next 24 hours...except along the 
coastline. Satellite fog product as of 08z showed a very shallow 
marine layer...but it has been shrinking during the past couple of 
hours. Localized IFR ceilings along the S Washington and far north Oregon coast 
through about 12z then VFR. Central Oregon coast fog and stratus 
getting pushed further to the S...thus konp may remain VFR through 
this evening. Models indicate another weak upper disturbance 
moving across northern Washington Wednesday night. Expect IFR ceilings to return 
to the coastline after 06z Thursday. 


Kpdx and approaches...VFR clear through 12z Thursday. Wind speeds to 
pick up late this afternoon...but not as strong as Tuesday. Weishaar 
&& 


Marine...pretty persistent pattern for the next few days. High 
pressure to remain anchored over the NE Pacific through Sat then gradually 
weaken. Thermally-induced surface trough will persist along the north 
cal and S Oregon coast for the next couple of days...which will 
maintain Small Craft Advisory wind speeds over the majority of the 
waters. Strongest wind will continue to be south of Cascade Head 
with gusts up to 30 knots during from the afternoon to early evening 
hours. Wind will ease late in the week and over the weekend as 
gradients diminish. Models in general agreement showing a switch 
to a fairly light south to southwest wind late sun. 


Generally wind-wave driven seas for the next few days...with steep 
and choppy conditions. A building northwest swell looks to arrive late 
Friday and Sat...possibly reaching 10 feet. This will be short-lived 
as models indicate seas falling back to around 5 feet by Sun night 
or Monday. Weishaar 
&& 


Pqr watches/warnings/advisories...

Cascade foothills in Lane County-central Coast Range of

Willamette Valley-greater Portland metropolitan area-lower
