NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service Portland or 
258 PM PDT Friday Apr 29 2016 


Synopsis...Post cold frontal showers will continue this 
afternoon...then dissipate tonight. There will be a return 
to dry and warm weather over the weekend and early next week as upper 
level high pressure builds over the Pacific northwest. Offshore winds will 
develop on sun. A southerly surge of marine air along the coast is 
expected Monday. An upper level trough will approach the coast toward 
the middle of next week...bringing warm southerly flow along with the 
potential for showers and possibly even some thunderstorms. 


&& 


Short term....tonight through Monday... 
a weak cold front moved through SW Washington and northwest Oregon 
today...bringing a period of light rain to much of the region. The 
steadier rain is now over the Cascades. A moderately unstable air 
mass behind the front is driving fairly widespread shower activity 
this afternoon. Based on the forecast model soundings...the depth of 
convection does not look deep enough for any thunderstorm 
development. An upper level ridge will approach the coast 
tonight...bringing warmer air aloft. This will act to stabilize the 
atmosphere and cause shower activity to taper off. A few showers may 
linger over the Cascades into early Sat morning. 


Clouds lingering over the Cascades and foothills after the overnight 
showers may backbuild into eastern portions of the Willamette Valley 
early Sat. The upper level ridge axis will push closer to the coast 
Sat. Dry northerly flow to develop at the lower levels...which should 
lead to clearing skies and considerable afternoon sunshine. 850mb 
temperatures will warm a few degrees to 5-6 c...which should allow afternoon 
highs to reach into the middle to upper 60s for the interior. The coast 
will stay cooler in the upper 50s to low 60s with an onshore 
component to the flow. 


Sunday will be even warmer and sunnier as low level flow is modeled 
to become offshore during the day. 850mb temperatures increase to 10 to 12 
c...which combined with the mixing in the lower levels due to the 
offshore flow should allow highs to climb into the upper 70s to low 
80s over the interior. The offshore flow should also allow the coast 
to warm up well into the 70s as well. 


A surge of southerly flow is modeled to develop along the coast Sun 
night into Monday. This will bring increasing low level clouds along the 
coast. Temperatures will cool considerably at the coast as well...with some 
of the cooler marine air also likely making it into southerly 
portions of the Willamette Valley as well. However northern portions 
of the valley may not see much marine influence at all...potentially 
allowing for temperatures to reach a few degrees higher than on 
Sunday. A splitting upper level trough will be approaching the coast 
Monday...which some of the forecast models are suggesting will bring enough 
middle level moisture and instability to generate a few showers or 
thunderstorms over the Lane County Cascades. Pyle 


Long term...Monday night through Friday. Broad upper trough over 
the eastern Pacific will split with an upper low closing off and 
taking up residence off of the northern California coast early next 
week. This feature will keep the region in south to southwest flow 
aloft...which will serve to send middle-level moisture into the region. 
Monday night likely remains dry...but by Tuesday some precipitation 
develops into the forecast area. While some model differences do 
remain and there is some question over just how much instability 
will be present...enough support from the forecast models to extend 
thunderstorm chances over the eastern portion of the forecast area 
for Tuesday and Wednesday. This upper low remains in place through 
midweek...before shifting onshore and into the Great Basin by late 
in the week. Temperatures will remain warmer than seasonal normals 
next week but gradually cool during the last few days of next week. 
&& 


Aviation...00z taf expectations...a wide spread in conditions at 
this hour as showers are ending at the north coast and about 
reaching their peak strength inland. Central coast has seen an IFR 
deck push on top of the konp vcty. Will continue to see conditions 
improve this evening as more stable air under northwest to north 
flow develop. Feel skies may clear up enough later overnight such 
that a stratus deck at roughly 015-020 will develop at most sites. 
Am expecting burnoff to occur around 18z inland and closer to 00z 
at the coast. Exception may be the south Willamette Valley and 
keug where northerly flow may pack the moisture longer over the 
field. 


Kpdx and approaches...bkn022-025 will be possible mainly through 
01z but some lingering showers may hang on and bring brief drops 
until 
03z. Then expect ceilings to remain 040-050 or better for several 
hours. Have reasonable confidence a stratus deck around 020-025 
will develop later overnight and remain through roughly 18z 
before inversions lift and the deck fairly rapidly breaks apart.

Marine...offshore swell hasn't really reached 10 feet and still 
may not reach 10 feet for the coastal waters tonight. However...will 
keep the Small Craft Advisory for seas in place as seas will be fairly steep with 9 
feet and 10-11 second periods wont take much of a boost to reach Small Craft Advisory 
criteria for steep seas. Still expect a several hour periods with 
winds gusting around 25 knots. Winds will ease for a time Saturday 
but thermal trough/low pressure over northern California and far 
southern Oregon will induce more of a summertime northerly wind 
pattern by Saturday evening and continue through much of Sunday as 
well. Strongest winds will likely be late afternoon through the 
evening. 


As the winds pick up...so will the choppy wind driven 
seas...reaching about 8 to 10 feet S of Newport at times in the 
afternoon/evenings. Will likely need small craft advisories for 
gusty winds and/or seas this weekend...but will not issue until 
the current series of advisories expire in order to avoid 
confusion. Jbonk
