NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
308 am PDT Sat Aug 29 2015 


Synopsis...an usually early and strong low pressure will produce 
widespread rain and strong winds across northwest Oregon and 
southwest Washington Saturday morning. A few thunderstorms embedded 
in the rain may enhance the wind threat Saturday morning. A second 
front pushing into the region from the northwest Saturday night will 
produce another round of rain. Additional showers will follow on 
Sunday. Expect cool weather and additional rounds of showers for much 
of the upcoming work week. 


&& 


Short term...a few prefrontal showers remain over the North Valley 
this morning with the frontal rain band moving onshore. Radar already 
showing some higher reflectivity activity over the Coast Range and 
even a few lightning strikes. Although the rainband is narrow...its 
currently moving much more north than east so it will be slow to 
work its way inland and may drop 0.10 to 0.20 inches of rain per 
hour with more in embedded stronger showers or thunderstorms. There 
does not appear to be any rain immediately following this frontal 
band...so there will be a definite break in rain from the time the 
band moves through to when any showers begin to pop up this 
afternoon with daytime heating. Have dried the forecast out quite a 
bit 18z today to 00z Sunday but the rain may have moved through 
earlier than even that. 


The parent low continues to strengthen and is currently centered 
about 200 miles west of North Bend according to latest infrared satellite 
imagery. Based on comparison of buoy observation and 06z NAM and GFS 
forecasts...looks like the low is around 989 mb right now...or 
slightly stronger than the NAM and GFS have. The 08z hrrr shows a 
stronger low currently and forecasts the pressure dropping to 985 mb 
at its closest approach to the Oregon coast...about 100 miles 
offshore. This would be 4 mb stronger than the NAM and GFS currently 
show but with a similar track and seems fairly realistic. Hrrr also 
shows rather impressive pressure rises behind the low late this 
morning with 6+ mb in 3 hours over the extreme northwest Oregon and SW 
Washington areas...mostly centered around Clatsop and Pacific 
counties. Also seeing high pressure rises just offshore through the 
central Oregon coast which should translate to high 
winds...especially for the beaches and headlands. Will keep high wind 
warnings in place as is. Pressure rises and pressure gradient through 
the valley are less impressive with the north-south gradient peaking 
only at about 4 to 5 mb but conditions will be noticeably windy 
nonetheless. 850 mb winds in the valley are forecast to be 40 to 50 
knots when this morning's rain comes through...so any convection could 
mix down some good gusts. Will leave Wind Advisory as is since this 
is an anomalously strong wind event for late August...even though 
technical criteria may not be met. 


Models have trended wetter with a second front dropping southeastward 
out of the Gulf of Alaska that will push a healthy dose of rain 
across the area Saturday night. Decent onshore flow and instability 
should lead to more showers and possibly a wet thunderstorm or two 
Sunday. 


Below average temperatures and additional rounds of wet weather 
appear likely next week. Bowen 


Long term (previous discussion)...Monday night through Friday. The 
Fall-like weather pattern will continue next week with primarily 
cooler than normal temperatures...cloudy conditions...and chances for 
additional rain. A trough will remain near the Pacific northwest 
coast through most of the period with some rain at times...especially 
during the early and middle parts of next week. Little change made to 
the current forecast. Tolleson 


&& 


Aviation...moist SW flow aloft over region...with rain increasing 
this am. Will see front push north across the region later this am... 
with increasing S winds. Strongest winds will be on coast and 
over Coast Range...with S wind gusts of 40 to 55 knots for those 
areas and lesser winds further inland. At 2 am...generally VFR 
conditions. But will see increasing MVFR along the coast by 12z. 
Rain will end by 18z for most areas...with ceilings breaking up a bit 
as more unstable air mass with showers moves into region for the 
afternoon. Would not be surprised to see transition back to VFR at 
times after 20z. Ceilings will lower back to MVFR tonight as another 
front and more rain pushes into the region. 


Kpdx and approaches...VFR...with rain until 18z...then likely to 
see a mixture of VFR with occasional MVFR as more showery pattern 
pushes into region. Will have S winds gusting 25 to 35 knots between 
17z and 23z. Winds ease after 00z...but will have increasing MVFR 
as rain increases later Sat night. Rockey. 


&& 


Marine...models continue to be well initialized with the strong 
low pressure now sitting about 250 miles southwest of Newport this am. 
This low will lift NE across the Oregon coastal waters and into 
northwest Washington today. But appears the actual low is stronger than 
the models indicate. The low will gradually weaken today as it 
moves NE...strongest winds look to remain S of the Columbia River. 
So...have issued Storm Warning for coastal waters S of the 
Columbia River where there is moderate to high potential for 50 knots 
gusts. Rest of the region will remain under a Gale Warning. 


Seas will be building as winds increase. Still looks good for seas 
to be running at 13 to 17 feet by middle to late this am. Seas hold in 
that range through the day...but drop back this evening. 


Winds will ease later this afternoon...likely below 25 knots by 8 PM. 
Seas will also subside as winds ease...probably around 8 to 10 feet 
later tonight into Sunday. 


Unsettled weather continues into next week with seas staying 6 to 
9 feet through at least midweek. Rockey.
