NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
906 am PDT Monday Aug 31 2015 


Synopsis...a warm front will bring light rain to areas north of a 
Tillamook to Montana Hood line today. Another front will arrive on Tuesday... 
then a showery air mass for Wednesday through Friday as an upper level trough 
moves across. Drier and warmer weather returns next weekend. 
&& 


Short term...radar and surface observations have shown rain over 
western Washington this morning extending S into extreme northwest Oregon...where 
the rain has been on the lighter side. Rain was occurring in an area 
of moist onshore flow...to the north of a surface ridge that extended 
west-southwest to east-northeast across Oregon. Models showed this pattern unlikely to 
change much today...so will keep probability of precipitation high in the northwest corner of the 
forecast area...and taper probability of precipitation off quickly to the southeast. 


Remainder of short term discussion unchanged...front will stall over 
the region tonight...then lift back into Washington state. As 
such...rain threat will also lift northward. But will keep quite a 
bit of clouds over region tonight. 


The next front will move into the region later Tuesday. Once again... 
will clouds increase Tuesday am...with rain threat increasing over region 
from northwest to southeast during the day. This front will bring better threat of 
rain...but again main area of rain will be on the coast and inland 
areas to north of Salem. Once that front passes late Tuesday 
afternoon...air mass will cool...with showery weather on tap for Tuesday 
night and Wednesday. Snow levels also drop down to near 6000 feet...but only 
expecting minor accumulations. 


Models all agree on cool showery weather continue on Wednesday. Many areas 
will likely remain in the 60s for high temperatures on Wednesday...even 
inland. To early to tell yet...but with cool air mass over the region 
and decent instability...could see a few thunderstorms over the 
region. Will let later shifts look at the potential. Seems first few 
days of September will feel likely early October. /Quinton 


Long term...no changes. Previous discussion follows. Wednesday 
night through Sunday. The upper level trough axis will remain near 
the coast late Wednesday into Thursday and tries to slide 
eastward...though models suggest this will be slow to occur as a few 
shortwaves on the back side of the trough may slow the progress as 
the trough slides a bit south. This will bring continued cool...and 
at times showery...conditions to the region for Thursday and 
Friday...with the base of the trough overhead Friday before shifting 
east of the Cascades. Heights look to rise a bit for the weekend for 
dry and warmer weather...perhaps back to near seasonal normals for 
Sunday. Cullen 
&& 


Aviation...VFR conditions inland this morning with localized MVFR 
ceilings for the coast. Expect more widespread MVFR ceilings for the coast 
early this afternoon as a weak warm front begins to move inland. 
Expect localized and brief MVFR ceilings inland late this 
afternoon...Manly north of khio. The front will result in south winds 
gusting to around 25 knots along the north or and S Washington coasts between 16z 
and 20z. S winds in general will become SW this evening. 


A weak cold front will approach from the north late tonight. S 
winds will gust to around 25 knots along the coast Tuesday 9 to 15z.S 
winds will return inland around 9 z to the north and 13 to 14z 
for southern areas. Expect MVFR ceilings as the front drops from 
north to south Tuesday. 


Kpdx and approaches...cloudy with VFR conditions through Tuesday 
morning. Occasional light rain late this afternoon and evening. 
There is a better chance for MVFR ceilings with a weak cold front Tuesday 
night. Tj 


&& 


Marine...a weak warm front is moving across the waters today and 
will generate low end Small Craft Advisory southerly winds for 
north of Cascade Head through late this afternoon. There may be 
some localized small craft gusts ahead of an with the next frontal 
passage late tonight through Tuesday afternoon...but do not 
anticipate the higher gusts will be widespread or consistent 
enough to warrant an advisory. 


Seas will remain relatively steep today and tonight with 7 to 8 feet 
heights and 10 to 11 second periods. A surface low over the Gulf 
of Alaska...just offshore of Yakutat is generating a northerly 
fetch that will bring a brief period of 10 feet swell to the Oregon 
waters Wednesday. 


Surface high pressure will build over the NE Pacific Wednesday night 
and Thursday as a thermal low develops over northern California. This 
will bring a return of northerly winds to the waters Thursday and 
Friday. A low to the north will prevent a tight gradient and 
expect below advisory winds Thursday and Friday. Tj 


&& 


Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...Small Craft Advisory for winds until 6 PM PDT this evening for 
coastal waters from Cape Shoalwater Washington to Cascade Head or out 
60 nm. 


Small Craft Advisory for rough Columbia River bar until 9 am PDT 
this morning. 


Small Craft Advisory for rough Columbia River bar from 5 PM this 
afternoon to 10 PM PDT this evening. 


Small Craft Advisory for rough Columbia River bar from 4 am to 
9 am PDT Tuesday.
