NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
305 am PST Monday Dec 22 2014 


Synopsis...the frontal boundary that has been the focus of 
persistent rain this weekend was in the southern part of our forecast 
area this morning but was weakening...and the remaining rain will 
continue to decrease today with the threat of any additional flooding 
ending as an upper level ridge builds in the northeast Pacific and up 
into the Gulf of Alaska...squeezing off the supply of moisture. The 
remaining frontal boundary will lift north tonight as a weak front 
and may produce some areas of light rain. The next cold front will 
move into western Washington on Tuesday and begin to affect the far 
north part of our forecast area...slowly sag farther south into our 
area Tuesday night...then sweep through southwest Washington and 
northwest Oregon with a good shot of rain and lowering snow levels on 
Wednesday and early Wednesday night. Another disturbance will bring 
some showers to the area Thursday night and Friday. Then another 
decent system is likely by the weekend. Snow levels will be lowering 
during the second half of the week...possibly affecting the Cascade 
foothills and the Coast Range. 
&& 


Short term...the frontal boundary that was the focus of heavy rain 
over the weekend remained over northwest Oregon overnight and 
continued to produce some decent rainfall amounts our central and 
southern Cascade zones...slowing the recession of rivers in that 
area. Rainfall rates appear to be finally easing early this 
morning...and National Weather Service Doppler radar confirms this 
trend. Have thus ended the remaining portion of the Flood Watch. The 
models show 850 mb winds of around 30 to 35 knots across the southern 
part of our area overnight will decrease to 20 knots or less this 
morning...confirming this idea. 


Though this boundary weakens...it is forecast to slowly lift north 
later today and tonight as a weak warm front ahead of the next 
system. The models have been persistent and coming into better 
agreement with the details of some areas of light rain spreading 
north through the area tonight into early Tuesday. Amounts will be 
quite light. 


The cold front with the next system will move into western Washington 
on Tuesday...brushing our far northern zones...especially north of 
Portland. This front sags very slow southward on Tuesday night...not 
making much southward progress. Then a trailing short wave on the 
tail of the front develops into a new low along the front that then 
sweeps through southwest Washington and northwest Oregon Wednesday 
and early Wednesday night for a good shot of rain. Rainfall amounts 
of a half inch or more are likely...with some areas around an inch. 
Snow levels will finally be falling to more seasonal values on 
Wednesday and Wednesday night...likely affecting the Cascade 
foothills and the coastal mountains. Snow amounts could reach Snow 
Advisory thresholds with this system in the Cascades. Tolleson 
&& 


Long term...some showers will linger on Christmas day behind the 
rather vigorous Wednesday system. The models are now all showing a 
short wave dropping in from the northwest later Thursday night and 
Friday for more showers. Snow levels will remain near or a bit below 
seasonal values...with snow into the Cascade foothills and coastal 
mountains. The models are coming into better agreement for another 
cool system by early in the weekend for more rain and Cascade 
snow...with snow levels remaining more seasonal. The models are now 
showing more drying early next week with some east winds possible. 
For now have lowered probability of precipitation for early next week. Tolleson 
&& 


Hydrology...rivers are mostly receding this morning...and the Flood 
Watch has been cancelled. The only rivers remaining above flood stage 
are the Marys River near Philomath and the Luckiamute near Suver. 
These are receding very slowly at best and will remain above flood 
stage for a while today. Tolleson 
&& 


Aviation...not much change this am. Mix of low VFR and MVFR across 
much of the region this am. Even pockets of IFR ceilings along the coast 
and peppered further inland. Will slowly trend towards VFR conditions 
between 19z and 23z. As a warm front lifts north across region later 
tonight...will see low VFR ceilings with areas of MVFR ceilings reform. With 
light winds...threat of fog and IFR stratus will increase 
tonight...especially for valleys to S of ksle. 


Kpdx and approaches...generally VFR today and this evening. Expect 
occasional MVFR ceilings near 2000 feet with drizzle through 16z. Will be 
dry this evening...but will have patchy fog and possibly IFR stratus 
late tonight into early Tuesday. Rockey. 
&& 


Marine...benign pattern with winds 15 knots or less. Warm front will 
lift north across the coastal waters late tonight into Tuesday am...then a 
cold front will push across the coastal waters Tuesday evening. Will see 
S to SW winds increase Tuesday afternoon...with gusts to 25 knots on the north 
waters at that time. Seas holding around 10 to 12 feet for next few 
days. 


Increasing potential for stronger winds again on the coastal waters 
Sat. Models indicate decent low pressure rolling across the NE Pacific into 
the Pacific northwest. Will have to monitor this week as this low could bring 
gales. Seas will be on the increase by next weekend...as fetch of 20 
feet swell from North Pacific arrives. 
&& 


Pqr watches/warnings/advisories... 
or...coastal Flood Advisory from 10 am to 4 PM today for 
the north and central Oregon coast. 


Washington...coastal Flood Advisory from 10 am to 4 PM today for the 
South Washington coast. 


Pz...Small Craft Advisory for hazardous seas today through 
Tuesday on all coastal waters. 
Small Craft Advisory for rough Columbia bar conditions 
for today through Tuesday.
