NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service Portland or 
256 PM PST sun Nov 23 2014 


Synopsis...a front is shifting south across northwest Oregon this 
evening...and should weaken over the area late tonight. Some 
thunderstorms will accompany this front through the early evening. 
Valley fog should develop early Monday morning. A warmer frontal 
system will bring additional rain to the area Monday afternoon 
through Thursday night. A dry day is expected Wednesday before 
another front moves through on Thanksgiving day. 


&& 


Short term...today through Wednesday...the cold front that stalled 
over SW Washington this morning has moved south into Oregon early this 
afternoon...generating plenty of lightning...thunder and heavy rain 
for northwest Oregon. The front...and thunderstorms will continue to move 
south late this afternoon as will the threat for thunderstorms. 
Thunderstorms may make it down to the Salem area around 4 PM and 
possibly even further south than that...down to Albany around 5 PM. 
However the front is expected to weaken around sunset...and think the 
threat for convection will weaken as well. 


The precipitation band will push south of the Washington Cascades 
this afternoon and have canceled the Winter Weather Advisory. The 
rain will decrease as it moves south this evening...and am not sure 
whether any rain will make it to Eugene. If so...it should be brief 
with light accumulations. Expect the rain to end by midnight tonight 
with clearing skies leading to fog in the interior valleys by Monday 
morning. 


The next frontal system will approach Monday. A warm front from the 
south will merge with a colder front to the north offshore before 
pushing onshore Monday afternoon. The warmer portion of the front 
will first move onshore Monday afternoon...before the colder front 
moves in Monday night and Tuesday. The snow levels should rise well 
above the Cascade passes by Monday afternoon. 


The front should move north Tuesday afternoon and evening as a an 
upper ridge builds over the area and a large upper low moves into the 
NE Pacific. The rain should mainly be confined to the northern Coast 
Range...coast...and northern Cascades by Tuesday evening. Besides a 
few morning showers over SW Washington early Wednesday morning...most 
of Wednesday will be dry. Should be a return of valley fog Wednesday 
morning. 


Long term...Wednesday night through Sunday...models continue to 
show a Pacific frontal system...associated with an upper level 
shortwave...moving across northwest Oregon and SW Washington on 
Thanksgiving day. There are still some discrepancies of when the 
rain will start. The European model (ecmwf) brings the front onshore during the early 
morning hours while the GFS holds off until daybreak. Expect chance 
probability of precipitation through Friday. The main upper level trough moves onshore over 
the weekend and will bring a much stronger and wetter system. Snow 
levels over the weekend could drop to the passes. As of now...it 
looks like we can expect to see hazardous travel conditions for 
those returning after the Thanksgiving Holiday. Temperatures in the 
extended continue to be at or above seasonal normals. Details of the 
impacts expected from next weekends system will continue to be 
refined with future updates. /64 
&& 


Aviation...a band of rain associated with a weakening frontal 
boundary is currently draped from just south of Tillamook through 
the northern and central Willamette Valley. This boundary will 
push slowly south and weaken further later this afternoon and this 
evening. Expect primarily VFR conditions during this time...with 
areas of MVFR from time to time underneath the heavier rain band. 
There is also still isolated thunder being detected along the 
frontal boundary...but this threat should end by early evening. 


Expect some clearing to develop later this evening and 
overnight and the atmosphere begins to stabilize. This should 
allow some patchy MVFR or IFR fog or low stratus to form 
overnight into early Monday morning. Another front will begin to 
spread light rain and possibly MVFR ceilings into the coast between 
21z and 00z Monday. 


Kpdx and approaches...a band of rain associated with a weakening 
front may temporarily reduce ceilings into MVFR through 00z. Some 
clearing tonight may allow patchy fog or low stratus to form 
overnight or early Monday morning. Pyle 
&& 


Marine...a weakening front has moved slowly from north to south 
through the waters today...and is now located just south of 
Tillamook. There is still isolated thunder being detected along 
the front...but expect this threat to end by late afternoon or 
early evening. Winds have dropped off this afternoon as the front 
has weakened...and are now westerly at around 10 to 15 knots. 
Thus...will allow the Small Craft Advisory for winds to drop off 
at 3 PM. Expect the lull in the winds to last into early Monday. Then 
the next front is expected to move into the waters tomorrow. The 
latest forecast models are indicating that low end gale force winds 
are a possibility tomorrow...mainly during the afternoon and early 
evening. Decided to issue a gale watch starting at 10 am. 


Winds may stay a bit gustier across the northern waters through middle 
week before a slow moving low pressure system begins to impact the 
waters middle to late next week. Low end gale force wind gusts might 
be squeezed out of this system at some point...but the scenario 
does not look all that promising for a solid gale force or higher 
wind event for the waters. 


Seas have come up just a bit today...and are now around 12 to 14 
feet. Expect them to remain fairly steady through this evening 
before gradually decreasing overnight and Monday. However...expect 
seas to remain above 10 feet into early Wednesday. Pyle

Pqr watches/warnings/advisories...

Washington Cascades. 


Pz...gale watch from Monday morning through Monday evening for 
coastal waters from Cape Shoalwater Washington to Florence or out 60 nm.
