NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland 
300 am PDT Monday may 4 2015 


Synopsis...one more mild day today after morning low clouds. Then 
changes as cooler and more showery weather arrives tonight and lasts 
through Wednesday. Dry and milder weather with building high pressure is on tap 
for the end of the week...and possibly into mothers day weekend. 
&& 


Short term...light onshore flow this am will gradually increase 
today. Low clouds are hugging the coast into the Coast Range...and 
will continue moving inland this am. Best threat of these will be in 
the Cowlitz...and Columbia River valley...then curling into the north 
Willamette Valley after sunrise. Other areas of the interior will 
also see low clouds form this am...especially over central and south 
Willamette Valley. But will see clouds break up by late morning into 
the afternoon...with another mild day on tap. However... due to the 
onshore flow...highs today likely only in the middle to upper 60s for 
the interior. Coastal areas will have more clouds persisting with 
highs in the 50s to near 60. 


First threat of rain will arrive this evening and tonight as a front 
approaches from the west. However...this front is not holding 
together all that well...so rain will be spotty with best threat over 
the coastal areas into the Coast Range later this evening. 


The main upper low center will initially be located to our north... 
but enough energy will swing around the southern periphery of the low 
to sag the cold pool into our forecast area by Tuesday. Look for 
increasing showers to spread into the coast late tonight and inland 
Tuesday in the increasing onshore flow. Small hail...gusty 
winds...and heavy showers are possible Tuesday and Tuesday evening. 
Snow levels will lower to around pass elevations on Tuesday...but 
snow amounts will tend to be on the lighter side. Based on earlier 
shifts map analysis...and current model trends...will cut back on 
threat of thunder a bit more for Tuesday as instability seems to be 
slowing on its arrival. Coldest air aloft arrives late Tuesday night and 
Wednesday...so seems that will be our best threat for any thunderstorms. 
Still...just keeping at a slight chance for now across northern zones 
on Tuesday...then but further south and inland to Cascades on Wednesday. 


The upper low moves inland and east of the Cascades by Wednesday... 
with some energy digging south into California and Nevada. The flow 
aloft and at low levels becomes more northerly...but there is still 
ample energy dropping south on the back side of the low to keep a 
threat of showers going from the Coast Range westward. There looks to 
be some instability as well. The afternoon heating of the day will 
probably lead to an afternoon and evening peak in the shower and 
thunderstorm activity on Wednesday. However...the coast will see the 
threat of showers decrease on Wednesday as the main driving forces 
move inland. 


Long term...Wednesday night through Saturday. The upper low pressure 
will slowly continue sliding towards the Great Basin or perhaps into 
central California...with some significant divergence among model 
solutions. Meanwhile high pressure will begin to build over the 
eastern Pacific. Will dry out Thursday and Friday for most areas...but will 
hold on to a minor chance of showers on the Oregon Cascades for the 
afternoon/evenings. Otherwise...high pressure offshore will build and 
bring drier weather with a return to mild temperatures. Another 
weakening front will arrive next weekend. Likely to be dry...but not 
certain yet. Will keep a very minor threat of showers in forecast at 
this point. 
&& 


Aviation...low end MVFR ceilings have set in along the coast and are 
trying hard to push inland at this hour but are mostly filling the 
coastal valleys. Expect some retreating to perhaps just offshore 
but dont feel it will last significantly long enough for pilots 
not to carry extra fuel as sea breeze winds develop relatively 
early under clearer skies aloft. An approaching front will 
reinforce the lower deck allowing it to persist through 05/12z. 
A stray thunderstorm may appear after 05/06z but have far too low 
of confidence for taf inclusion at this point. 


For inland terminals...satellite fog product appears to be 
hinting at some stratus trying to develop in the central and 
southern Willamette Valley but am not seeing anything definitive 
just yet. Will continue to carry the hints of a low end MVFR deck 
for the northern inland tafs and a broken deck for ksle and keug. 
Expect peak coverage will develop around 13z near sunrise then 
scattering around 17z except perhaps closer to 19z for keug. 
Expect to see a low end VFR ceiling start pushing in from an 
approaching weak front around 00z then lowering to around 025 
closer to 06z with light showers becoming possible. 


Kpdx and approaches...VFR through 05/06z. Approaching front lowers 
ceilings to around 040 after 00z then down to around 025 after 06z 
with increasing shower activity. /Jbonk 
&& 


Marine...high pressure exits the area today. Approaching front 
continues to weaken per models with only an outside chance of 
gusts exceeding 21 knots Small Craft Advisory criteria over the next 
24 hours. May get sporadic gusts 25 to 30 knots under showers and 
possible thunderstorms Monday night through Tuesday. 
Otherwise...models 
keep winds somewhat below 20 knots until surface heat low develops 
along the SW Oregon coast Thursday and Friday. May get northerly 
20 to 25 knots gusts for the central waters then. 


Bigger concern will be a complicated set of swells crossing the 
waters for the next few days. Dynamic fetch under easing winds 
brings a west-northwest swell of 8 to 10 feet in Monday night and Tuesday. All 
the while... a pair of long period 2 and 3 feet swells...periods 17 
and 22 seconds respectively...cross from the south. Add in some 
wind wave and the confused seas will add up and exceed 10 feet for 
the better part of this evening through Tuesday evening. The long 
period southerlies will continue through Wednesday before easing 
back to the typical background values. Overall seas will then 
remain 6 feet or less but continue to show multiple distant 
sources in addition to locally induced wind waves. /Jbonk 
&& 


Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...Small Craft Advisory for hazardous seas from 8 PM this evening 
to 9 PM PDT Tuesday for waters from Cape Shoalwater Washington to 
Cascade Head or from 10 to 60 nm-waters from Cascade Head 
to Florence or from 10 to 60 nm. 


Small Craft Advisory for hazardous seas from 2 am to 8 PM PDT 
Tuesday for coastal waters from Cape Shoalwater Washington to 
Cascade Head or out 10 nm-coastal waters from Cascade Head 
to Florence or out 10 nm.
