Severe Weather Alert Descriptions

 Special Statement  Statement as of 3:00 PM PDT on October 23, 2014


... Potential for strong wind this weekend for southwest Washington
and northwest Oregon...

A low pressure system is forecast to develop well off the
northern California coast Friday and move northeast toward the
Oregon and Washington coast Friday night... and then move inland
Saturday. There is the potential for high wind along the coast and
windy conditions in the Willamette Valley and southwest Washington
interior lowlands. There is still plenty of uncertainty regarding
the strength and timing of this system. Should high winds
occur... downed trees and power outages would be possible. At this
time it looks like the strongest wind would occur late Saturday
afternoon through the evening.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
945 am PDT Friday Oct 24 2014 


Synopsis...a warm front will spread light rain into SW Oregon 
this morning and across northwest Oregon and SW Washington in the 
afternoon and evening. A cold front will push inland Saturday 
afternoon and evening. An upper trough will continue showers 
through Sunday. Another frontal system is expected early next week. 


&& 


Short term...today through Monday...krtx Doppler radar showing some 
light returns across the south part of the forecast area this 
morning. 15z metars not indicating any precipitation...even at keug. 
Suspect most of the echoes across Lane County are virga. Patchy fog 
and low clouds in the interior valleys as well. Water vapor satellite 
imagery clearly shows the developing low pressure area near 39n 133w at 
15z. Warm front extending outward from the low center across southern 
Oregon...which will continue to lift north during the day. 


Offshore low-level flow will gradually strengthen during the day. 15z 
kttd-kdls gradient was -2.6 mb...which is a bit stronger than the 
3-hour 12z NAM forecast. Gradient likely to be around -3 to -3.5 mb by 
00z Sat...enough to produce breezy conditions at the west end of the 
Columbia Gorge. Areas north of ksle likely to remain dry through at least 
early afternoon. 


Biggest short-term forecast challenge remains the developing low. 
Models seem to be coming into better agreement with the depth and 
track. By 12z Sat the 12z NAM...06z GFS and 00z European model (ecmwf) show an 
elongated low...with the primary low center at 41n 129w. Some 
differences start to crop up at the 18z time step...with the NAM 
moving the low further north up the Oregon coast compared to the 06z GFS 
and 00z European model (ecmwf). The 00z WRF-GFS backed off on the peak wind gusts for 
the central Oregon coast. The 12z Thursday run showed a small core of 
60-70 knots gusts early Sat afternoon between Newport and Florence. The 
00z run knocked these down to around 50 knots. The 12z NAM does indicate 
two separate low centers 18z Sat...with the tightest S gradient along 
the north California coast. The NAM does show 50 knots 975 mb wind speeds 
along the central coast 18z Sat...but by 21z the strongest 975 mb 
wind speed is around 40 knots. Not convinced the coast will reach 
high-wind criteria. Would not rule out isolated 55-60 miles per hour wind gusts 
on The Headlands between 18z Sat and 00z sun. Have higher degree of 
confidence for blustery conditions in the Willamette Valley. Expect a 
brief period (2-4 hours) of windy conditions as the surface low moves 
north-NE into SW Washington late Sat afternoon and early evening. 12z GFS shows a 
+13 mb 6-hour pressure change bullseye near konp 06z sun...which is pretty 
close to benchmark thresholds to get windy conditions in the valley. 
Would like to see this isallobaric change in a more south-to-north 
orientation. In any event...current forecast of 35-45 miles per hour gusts in 
the Willamette Valley late Sat afternoon through early evening looks 
good. Strongest gusts should be S of ksle. 


A broad upper trough...similar to what was over the area 
Thursday...settles over the region Sunday. This will bring additional 
short-waves through the forecast area Sat night and Sunday. Snow 
levels fall to near Cascade Pass levels Sunday. Weak ridging moves 
over the area Sunday night and into Monday morning with rain chances 
dwindling briefly before the next system approaches. Weishaar 


Long term...no changes. Previous discussion follows...Monday night 
through Thursday night...an active weather pattern continues through 
next week. The next frontal system...including the remnants of 
Hurricane Ana...will move through the region Monday night into 
Tuesday bringing continued rain and winds along the coast. Shortwaves 
will support rain through Wednesday. Beginning around Thursday the 
models diverge significantly to the extent that climatology seems the best 
bet at this point for the remaining 24 hours of the forecast period. 
Bowen/27 


&& 


Aviation...VFR conditions with ligth rain...mainly 
south...through around 19z. A few locations with MVFR or IFR ceilings 
possible this morning. The warm front will lift north after 19z 
and spread rain into northwest or. Expect conditions to remain mainly VFR 
with occasional periods of MVFR ceilings. Rain decreasing after 08z as 
the warm front moves into Washington. 


Kpdx and approaches...mainly VFR conditions through tomorrow 
morning. A few light showers are possible this morning before 
more general rain develops...mainly after 19z as the warm front 
lifts into northwest or. /64 


&& 


Marine...mild conditions expected today with light east winds this 
afternoon. A deepening low pressure system is expected to approach 
from the SW and move through the coastal waters on Sat and inland 
late Sat. The track and strength of the low is still uncertain at 
the moment as models have the low becoming more elongated...but 
still expecting southerly gales with this system. The gales will 
bring steep seas with wave heights approaching 20 feet possible 
through Sat night. 


As the low moves inland winds will become west and decrease with seas 
lowering to around 8 to 10 feet as high pressure builds into the Pacific northwest. 
Another shortwave expected to approach the region early next week.
