NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
953 am PST Monday Jan 26 2015 


Synopsis...a strong upper ridge will flatten and move away to the 
east today and tonight...gradually weakening the low level inversion. 
A very weak frontal system will approach the coast late 
tonight...begin to spread inland in the north Tuesday...then linger 
over northwest Oregon and southwest Washington through Wednesday. 
Another upper ridge is expected to develop over the Pacific northwest 
later in the week and continue into the weekend. The next chance for 
rain is probably not until later next weekend or early next week. 
&& 


Short term...the fog is holding tough in most inland areas except 
near Troutdale...so will continue the dense fog advisory this 
morning. The fog and low stratus will again be slow to clear 
anywhere...and probably persist in most inland areas except near the 
Columbia River again today as light surface pressure gradients are 
again the rule. The upper ridge that has been over the Pacific 
northwest the last couple of days is moving east and weakening or 
flattening which will weaken the temperature inversions aloft but not 
enough to mix the fog vertically. Expect more to thicken and 
redevelop tonight. 


There is a frontal zone out near 130w that the models continue to 
show will move into the coastal waters and close to the coast 
tonight. This system will weaken a lot as it approaches. It will turn 
the low level flow onshore near the coast...as evidenced by the bank 
of low clouds just off the coast. Expect some light rain or drizzle 
to reach especially the north coast tonight and early Tuesday. The 
frontal band will slowly ease inland along the Columbia River 
Tuesday...then hang up over the northern part of our forecast 
area...say from about Salem northward...Tuesday night and Wednesday 
before slowly drying out. Amounts will be light...but expect some 
drizzly periods with some light rain Tuesday night into Wednesday. 
Some drizzle should also reach the central Oregon coast...but expect 
it to probably stay dry in the south Willamette Valley. Tolleson 


Long term...no changes. Previous discussion follows... 
Wednesday night through Sunday...a passing shortwave late Wednesday night 
may provide enough lift for a few showers...mostly along the north 
coast and Coast Range and into SW Washington. Models remain in good 
agreement that a ridge of high pressure aloft rebuilds on Thursday and 
persists through the end of the week. This will maintain dry 
conditions but bring daily fog and low clouds to Interior Valley 
locations. The ridge will likely break down and shift inland some 
time next weekend...but still some uncertainty as to if this will be 
Sat or sun. The 12z GFS is a bit more aggressive in bringing a moist 
frontal system to the region by late Sat night...while the European model (ecmwf) 
would keep things dry until Sun night. Increased probability of precipitation a bit for next 
weekend...particularly for the northwest portion of the forecast 
area...though restricted to lower end chance for Sat night through 
sun given the support for the later timing from the European model (ecmwf) and 
numerous gefs members. Cullen 
&& 


Aviation...high pressure and a strong inversion continue to maintain 
LIFR/IFR fog across the interior taf sites this morning. Expect 
little change at keug...ksle...and perhaps khio...through next 24 
hours. If a few hours of clearing do develop after 21z today...expect 
it to be short lived with a return to fog shortly after 01z Tuesday. East 
winds pouring out of the Columbia River gorge are helping to keep 
kttd mostly clear...and may aid in mixing at kpdx. The east winds 
should subside later today...and IFR or lower conditions return to 
kpdx tonight...but perhaps later and higher at kttd. Conditions 
remain VFR and generally clear along the coast. A southerly wind 
reversal will work its way up the coast bringing IFR onshore later 
today or tonight...though confidence in timing this remains low given 
large model uncertainty. 


Kpdx and approaches...LIFR fog continues at the terminal this 
morning. Light east winds through the Columbia River gorge continue 
may aid in mixing a bit later this morning or early afternoon. Still 
considerable uncertainty as to timing of improvement of fog/low 
stratus...but suspect this may occur around 20-21z. A return to LIFR 
fog appears likely again after 01z Tuesday. Cullen 
&& 


Marine...a southerly surge has begun across the southern and central 
Oregon coast and will continue to push north over the waters and 
coastline. Expect a brief period of gusts around 20 knots with a few 
occasional gusts close to 25 knots possible through early this 
afternoon. However...do not expect these to be frequent or widespread 
enough for an advisory. Seas will hold around 8 or 9 feet today...but 
may touch 10 feet at times especially where the wind wave component 
increases with any stronger gusts later this morning. 


A weak front will slide southeast across the waters for Tuesday bringing a wind 
shift but no significant increase in speed. High pressure then 
rebuilds by Wednesday or Thursday and will persist into at least the start of 
the weekend. Seas will gradually subside slowly through the second 
half of the week...remaining well below 10 feet. A more active pattern 
may develop late in the weekend...with increasing seas and 
winds...though some uncertainty remains in the timing and strength of 
these systems. Cullen 
&&

Willamette Valley-greater Portland metropolitan area-lower 
Columbia-south Willamette Valley.
