NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
910 am PDT Sat Oct 25 2014 


Synopsis...a low pressure system will move north up the Oregon coast today 
then move inland over SW Washington towards Puget Sound sound this evening 
bringing windy conditions to the region this afternoon and evening. 
A cold front will follow the low turning the flow onshore tonight 
and sun as an upper level trough moves across. Weak high pressure will 
move across the region Sun night...then another frontal system will 
move in Monday and Tuesday as a low pressure system moves into British Columbia. 


&& 


Morning update...the main change this morning was to expand High 
Wind Warning coverage into the central Oregon Coast Range...Willapa 
Hills and the entire Willamette Valley...and move up the starting 
time of existing high wind warnings along the Oregon coast. 


A low pressure somewhere in the upper 980s mb range is sliding north 
northeastward off the central Oregon coast where it is approximately 
75 to 100 miles offshore. Winds have been blasting along the southern 
Oregon coast and higher locations across interior southwest Oregon. A 
number of stations in this general region have reported gusts between 
60 and 100 miles per hour so far. While some of the global models suggest the 
low pressure will slowly fill for the remainder of today...the rap 
actually holds the strength of the low pressure steady for the next 
6 to 8 hours...even deepening it slightly to 987mb before it makes 
landfall somewhere around Pacific or Grays Harbor counties in 
Washington this afternoon. The rap also peaks the kpdx to keug 
pressure gradient around 10 mb and is just over 20 mb between kast 
and kbok this afternoon. The rap also suggests a 3 hour pressure 
rise of greater than 9 mb pushing north-northeastward into the 
Willamette Valley late this afternoon and evening. Coupled with an 
increasingly unstable atmosphere across northwest Oregon 
today...high winds aloft should have an easier time mixing down to 
the surface. 


Wind gusts to 60 miles per hour for central Oregon coastal communities and 75 to 
80 miles per hour gusts along beaches and headlands should begin shortly as the 
low pressure moves northwestward of these locations. Winds will be 
slower to start along the north Oregon coast...but should begin 
around midday. Further inland across the Willamette Valley...wind 
gusts of 40 to 55 miles per hour appear likely this afternoon with gusts to 60 
miles per hour certainly possible. The highest winds appear most likely to 
impact the Willamette Valley between 1 PM and 5 PM. It will certainly 
remain breezy after this time frame...but that is the time of 
highest concern right now. Given foliage...the ground is relatively 
saturated...and the aforementioned meteorological factors...opted to 
issue a High Wind Warning for all the Willamette Valley where power 
outages and down tree potential appears higher than we have seen in 
quite some time despite some uncertainty in exact wind speeds. 


Given the exact track of the low remains uncertain...will keep the 
Special Weather Statement going for the South Washington coast...and 
the Wind Advisory for the lower Columbia Interstate 5 corridor zones. 
However...high wind potential certainly exists for these zones this 
afternoon so we will continue to monitor trends and model data in 
case warnings appear necessary for these locations. 


The mention of thunder was also expanded into interior locations for 
this afternoon and evening. Will monitor radar closely for any 
convective elements that warrant short fused warnings. /Neuman 




Previous discussion below... 


Short term...surface low was seen in satellite imagery near 40n 
129w at 08z moving NE. Buoy 46002 showed a pressure of 990 mb north of the 
low...suggesting a central pressure at least a few mb below 990. Overall 
prefer the European model (ecmwf) for placement and pressure...although models have come 
around to a much more cohesive picture of low. A southerly jet along 
the east side of the upper trough suggests a turn to the north for the low 
today...which models now uniformly bring up just off the Oregon 
coast today while beginning to fill. There is a little spread in 
where the models bring the low inland...but consensus seems to 
suggest the low making landfall on the S Washington coast between 21z and 00z 
today before heading towards the S Puget Sound sound area. With surface 
pressure gradients generally depicted around 14 to 16 mb down the Oregon 
coast as the low moves inland...will Post high wind warnings for the 
central and north Oregon coast and the north Oregon Coast Range. S Washington coast 
is a little iffy based on the uncertainty of the exact track of the 
low. With the best guess for the low moving inland over Pacific 
County will hold off on any warnings for the S Washington coast and Willapa 
Hills...although it may ultimately require a warning later today. A 
the track of the low expected across the S sound suggests windy 
conditions extending into the Willamette Valley and I-5 corridor 
late today and this evening. Models indicating about a 6 mb pressure 
gradient between keug and kpdx as the low passes by to the 
north..probably not enough for a High Wind Warning but gusts to 50 miles per hour 
nonetheless. Overall the peak winds today and this evening expected 
to be relatively quick to pass as the low moves through quickly and 
cold front follows quickly. 


Lighting indicated on lightning detection networks to the north of the 
low early this morning offshore. Will add a mention of thunder to 
the coastal waters today as the low lifts north...and include a slight 
chance in SW Washington late today. With the warm front already north and the 
low passing by to the north...rainfall is not a complete gimmie 
today...especially points further inland. Better probability of precipitation will come tonight in 
the westerly onshore flow following the cold front as the colder air 
aloft with the upper trough destabilizes the atmosphere and 
orographics add lift to the windward mountains. The cooler air 
following the front expected to drop snow levels down to around 4500 
feet by Sun morning...in time to expect at least a few inches of snow 
for the passes in the orographic showers. 


A weak ridge Sun night will bring a slow end to the showers as well 
as some cooler temperatures. The next system though...this one tracking east 
across the North Pacific towards British Columbia...will bring the next threat of rain 
to the north part of the forecast area Monday in an area of moist warm air 
advection. 


Long term...no changes. Previous discussion follows. The long term 
starts out wet with the next system moving into the forecast area 
Monday night. This system contains the remnants of Hurricane Ana...that 
skirted Hawaii last week. Models may be under doing the potential 
with this one. A strong jet stream will remain directed at Washington and 
northern Oregon through Tuesday night. Models show large variations beginning 
Wednesday...but expect the active pattern to continue. The European model (ecmwf) and GFS 
show a trend toward drier conditions late next week as a deep low in 
the Gulf of Alaska amplifies the downstream ridge over the 
intermountain west. Weishaar 


&& 


Aviation...low pressure off the Oregon coast will push NE today and 
then inland over western Washington later this afternoon. Strong S 
to SW winds aloft today...with gusty S to SW winds down to ground 
through 03z. Strongest winds 20z to 01z. Mostly VFR...but will 
have pockets of MVFR under showers. Expect isolated thunderstorms...mainly 
from Coast Range and westward. Conditions relax after 03z...with 
considerable low VFR and MVFR ceilings through the night. 


Kpdx and approaches...clouds and showers will increase this am... 
and continue into this evening. Mostly VFR...but will have 
occasional MVFR ceilings at times. Winds will turn southerly and gusty 
after 17z...with strongest winds between 21z and 02z when gusts 
may reach 40 knots at times. Rockey. 
&& 


Marine...a 985 mb low is now about 200 miles west of North 
Bend and is moving the northeast. Low is expected to move onshore 
just north of Willapa Bay later this afternoon. Solid southerly 
gales on the waters today. Strongest winds in 2 to 5 PM period at 
which time may have brief coastal jet development. Winds will turn 
west to southwest and ease this evening. 


Seas generally 10 to 12 feet this morning...but should build quickly 
later this morning into the afternoon. Buoy off Port Orford now at 
27 feet...so give more confidence in boosting wave heights on Oregon 
coastal waters for today. Will see peak out near 20 feet from about 
Tillamook southward...and 15 to 18 feet further to the north. Seas will 
subside this evening as winds drop. Rockey.
