NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland 
329 am PDT Sat may 30 2015 


Synopsis...a flat upper ridge over the Pacific northwest weakened a 
bit Friday and Friday night as very weak short wave energy moved 
through and lowered 500 mb heights about 30 dm. The resulting west 
to southwest flow aloft reinforced deepened the marine layer that 
was pushing inland through the coastal gaps and will likely spread 
into parts of the inland valleys this morning. Occasional higher 
clouds will move through as well. Expect a bit of cooling today. The 
upper flow will turn more southerly later tonight and Sunday ahead 
of the next low off the coast...sharpening the upper ridge... 
restricting the marine layer more to the coast again...and allowing 
inland temperatures to warm. As the low moves onshore Sunday night and 
Monday...look for more clouds...and chance of showers and possibly a 
few thunderstorms even at night...as well as substantial cooling. 
The cooler unsettled pattern will continue through middle week or 
so...then some drying and a bit of warming is possible late next 
week. 
&& 


Short term...tonight through Monday...a flat upper level was over 
the Pacific northwest...pinched by an upper low in b.C. That will be 
moving east Sunday...and an upper low off the northern California 
coast between 130w and 140w. Some weak upper level short wave energy 
moving through overnight has lowered 500 mb heights about 30 dm over 
the region...and this has reinforced and deepened the marine layer 
along the coast. Middle and high clouds have been obscuring the low 
clouds...but they have been pushing inland into the coastal gaps and 
expect some areas of low clouds to reach the Willamette Valley this 
morning. All of this suggests some more additional cooling inland 
today...with inland temperatures in the upper 70s to around 80. This will 
keep brisk west winds through The Gorge continuing. Any chance of 
thunder in the Cascades will be slim today...mainly near the Cascade 
crest in Lane County. 


The low west of California will approach from the southwest tonight 
and Sunday...backing the upper level flow to more southerly. This 
will restrict the inland penetration of low clouds Sunday morning... 
and as a result allow temperatures inland to rise again...into the 80 to 85 
range. The only restricting factor to the warming will be higher 
level clouds again. As the low approaches and begins to move onshore 
Sunday night...diffluent southerly flow aloft develops that will 
likely lead to an increasing threat of showers and thunderstorms. 
Some thunderstorms may develop over the Oregon Cascades late 
Sunday...but then some nocturnal thunderstorms are possibly in the 
Cascades and foothills and possibly even in the Willamette Valley. 
We will also see a southwest marine push develop Sunday night and 
Monday morning that will bring cloudy conditions and substantially 
cooler temperatures...possibly 2 to 4 degrees below normal. This could 
restrict the threat of thunder to east of the Coast Range... 
depending on its timing. 


After the low moves through late Monday and Monday evening...the 
models show a trailing westerly flow with several short waves moving 
through that will maintain the strong onshore flow with occasional 
showers into the middle of next week. Tolleson 


Long term...no changes. Previous discussion follows... 
Monday night through Friday...by Monday night the base of a 
negatively tilted upper level trough will be passing over the region. 
The cold core of the upper low will move from west-southwest to 
north-northeast across the forecast area by early Tuesday and bring 
continued showers and a slight chance of thunder in the Cascades. A 
shortwave trough may provide for additional showers on Wednesday so 
maintained a slight chance of showers across much of the area. 
Confidence is somewhat lower for second half of the week. Expect 
Thursday to generally be dry for most locations but models suggest 
the next upper trough will strengthen into a closed low. While the 
GFS maintains this low centered over Washington and Oregon for the 
end of the week...the European model (ecmwf) centers the low over California and into 
the southern Great Basin...which would enable some ridging to build 
over the Pacific northwest. Therefore given this lower confidence 
forecast...elected to maintain the current forecast of temperatures 
returning to near seasonal norms and areas of slight chance probability of precipitation. 
&& 


Aviation...solid MVFR stratus along the coast and into major coastal 
river drainages. Stratus already at kkls as of 08z. Coastal areas to 
remain MVFR...with localized IFR through the morning hours. Areas 
south of konp may see ceilings become broken middle to late afternoon. If this 
does occur...expect a return to overcast low-end MVFR or high end IFR 
during the evening. Elsewhere...southwesterly marine push occurring in the 
central and south interior valleys tonight. Good chance MVFR ceilings 
will develop in the south Willamette Valley around 12-14z. 
Also...expect low-end MVFR ceilings to develop in the SW Washington interior 
lowlands and far north Willamette Valley as well. Nearly all inland areas 
will be VFR by 18z Sat. 


Kpdx and approaches...VFR through 12z sun. However...expect low-end 
MVFR ceilings to develop at the terminal and vicinity between 12z and 
14z. Return to VFR by 17z. Weishaar 
&& 


Marine...rather benign marine conditions for the next several days. 
Wind speeds generally 15 knots or less...with afternoon and evening 
gusts up to 20 knots at times. 


Seas primarily 5 feet or less through next week. Spectral analysis 
suggests several 2 or 3 feet swell sets through early next week...any 
of which could be the dominant feature. Expect mainly wind-wave 
dominated conditions through the weekend...with a secondary 
longer-period SW swell. Weishaar

Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...none.
