NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
233 PM PDT sun Sep 21 2014 


Synopsis...weak onshore flow has returned today...dropping 
temperatures a few degrees today versus Saturday. This trend will 
continue into Monday as the marine layer deepens along the coast and 
thermal low pressure shifts east of the Cascades. There will 
probably be more extensive morning low clouds Monday...burning off 
inland by early afternoon. A dying front may hold together enough to 
bring a few showers to the coast Monday night...then further inland 
Tuesday. A more organized system will bring more widespread rain 
midweek...with cool and showery weather afterwards. After a long hot 
Summer...autumn weather may be arriving right on time. 


&& 


Short term...tonight through Wednesday...temperatures are generally 
down a couple degrees versus this time Saturday...as light onshore 
flow has replaced the offshore flow of yesterday. The most dramatic 
temperature drops have been along the coast...where onshore flow and 
low clouds are resulting in temperatures 10-15 degrees f cooler than this 
time yesterday. 


The marine layer is in the process of deepening...and will likely 
make a substantial inland push overnight tonight. By sunrise Monday 
it is likely much of the forecast area will be under a blanket of 
stratus. The low clouds will take a little while to retreat to the 
coast...probably sometime around midday or shortly thereafter. The 
increased cloud cover combined with 850 mb temperatures 3-5 degree c cooler 
than today should lead to maximum temperatures in the middle to upper 70s Monday 
and even that may be a little optimistic. 


This will be the beginning of a trend away from the persistent very 
warm and dry weather this Summer has brought. After 21 days of temperatures 
90 degrees or warmer at pdx...and a record 36 days at or above 90 
degrees in Eugene...it may be somewhat safe to say we have seen the 
last such heat of the season. As we near the end of September...the 
days are getting shorter...and the sun is getting lower in the sky. 
It becomes rapidly more difficult climatologically to achieve 90 
degrees as we move toward October. 


And this transition is happening right on cue...as the autumnal 
equinox is fast approaching - 723 PM PDT on Monday Sep 22. Monday 
evening a large upper low and trough will be approaching the Pacific northwest 
coast...likely to bring a significant amount of rain to our district 
as its associated frontal system slowly moves slowly onshore Tue-Wed. 
18z NAM continues to show some potential for a decent coastal jet 
setup along the coast Tuesday evening...perhaps bringing some south wind 
gusts 40-50 miles per hour to the beaches and headlands. This would be the first 
such event of the season. Current forecast does not reflect this just 
yet...as there is some potential for energy to be splitting as the 
front moves onshore. Lower pressure to the north and lower pressure 
to the south would cut down on the potential of south to north 
gradients to drive such wind gusts. 


Would not be surprised to see some locations see 1-3 inches of rain 
out of this event Tuesday through Wednesday...particularly coast and Coast 
Range. Inland areas could see upwards of 0.50-1.00 inch depending on 
how waves track along the frontal zone as it lumbers onshore. If rain 
gets heavy...it could be a concern for debris flows in some of our 
harder hit fire areas these past few weeks. Will continue to monitor 
this possibility and of course pass along more information as we 
learn the severity of these burn scars. Weagle 


Long term...after our slow-moving front clears the region Wednesday 
evening...models show decent agreement that an upper level trough 
will settle over the Pacific northwest. This will mean cool and 
unsettled weather with plenty of showers around for the rest of the 
week. It may take until next weekend for temperatures to rebound back to 
normal...though beyond Friday models have all sorts of different 
ideas of how to handle our pattern. Best guess is that some flat 
ridging will attempt to return by the weekend...followed by some 
frontal systems attempting to clip the Pacific northwest by early next week. 
This based more on pattern recognition than anything else...so 
confidence in any particular solution is rather low starting next 
weekend. Weagle 


&& 


Aviation...VFR conditions continue across the interior through 
this evening under generally clear skies...with the exception of 
some smoke from nearby wildland fires forming a scattered layer 
around 5000 feet. A deepening marine layer will push MVFR stratus 
into much of the valley by around 12z Monday. At the coast...IFR ceilings 
have scattered out for this afternoon...but likely push back 
onshore after 06z. With deepening marine layer and approaching 
upper trough...expect ceilings to remain higher IFR to lower MVFR 
overnight through at least middle morning Monday. Winds may remain gusty 
around 25 knots along the coastal areas through this evening. 


Kpdx and approaches...VFR conditions through 10z Monday then 
increasing chances for MVFR ceilings around 1500 feet as marine layer 
deepens and pushes inland. MVFR ceilings likely by 13z Monday...lasting 
through 17z Monday with improvement to VFR conditions thereafter. 


&& 


Marine...southerly winds continue across the waters through early 
this week. Will allow Small Craft Advisory for northern zones to 
expire at 3 PM as planned...though a few occasional gusts to 20-25 
knots possible this afternoon before easing this evening. 


A weakening front moves across the waters Monday afternoon and may 
bring another round of Small Craft Advisory winds...before a 
fairly strong low pressure system moves towards the waters on Tuesday 
night or early Wednesday. This second system will likely bring solid 
advisory level winds across the waters. 


Seas remain 5 to 7 feet through early this week...before building 
on Wednesday into the 10-15 feet range with strong low pressure system. Seas 
may linger around 10 feet through Friday...but model differences after 
Thursday increase uncertainty for the second half of the week. Cullen
