NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
242 am PST Thursday Jan 29 2015 




Synopsis...a very weak storm system will bring some passing clouds 
today and perhaps a sprinkle or two. Patchy valley fog and low clouds 
should give way to clearing skies this afternoon for most locations. 
Building high pressure and offshore flow should produce relatively 
mild temperatures...areas of valley fog and east winds near the mouth 
of the Columbia River gorge through Saturday night. A weakening storm 
system will likely bring a shot of rain to the area late Sunday and 
Monday before high pressure likely brings another bout of dry weather 
midweek next week. 




&& 




Short term...infrared satellite imagery early this morning reveals a 
mess of middle and high level clouds streaming northeastward ahead of a 
weak upper level trough sliding across the region. Underneath these 
clouds...enough radiational cooling has developed to allow patchy fog 
and low stratus to form in the Willamette Valley. In 
addition...Doppler radar indicates a few virga showers are moving 
northeastward across the area and models suggest this will continue 
through the morning hours. In the off chance a few of these showers 
materialize...added a mention of brief sprinkles to the forecast 
through this morning even though most locations should remain dry. 


Shortwave ridging will begin to shift over the region tonight...which 
should bring mostly clear skies and continued mild temperatures. 
However...the Willamette Valley...lower Columbia River valley and the 
Hood River Valley will see areas of fog and low clouds return 
Thursday and Friday nights. 


An easterly cross Cascade pressure gradient is already hovering 
around 6mb between Troutdale and The Dalles...and resulting in 30 to 
40 miles per hour gusts near Troutdale and 50 to 60 miles per hour gusts in the windiest 
spots in the western Columbia River gorge. Pressure gradients may 
strengthen a bit more...but should generally hold steady through 
Saturday and produce similar wind speeds through that time. East 
winds may strengthen a bit and become a little more widespread 
across the Portland metropolitan area Saturday night as the cold pool east 
of the Cascades deepens slightly and the inversion strengthens 
temporarily. 


A weakening front still looks on track to enter the forecast area on 
Sunday...or perhaps more likely Sunday night. Given the weakening 
nature of the front and the ridging that will be in place 
beforehand...probability of precipitation were trended towards the idea that a slower system 
is more likely. /Neuman 




Long term...Sunday night through Thursday...as we enter a more zonal 
flow pattern...models continue to disagree on precipitation 
distribution and timing Sunday night and Monday a warm front spreads 
into the region. Continued the idea that rain is likely during this 
period...but details still remain fairly uncertain. Despite these 
differences...both the GFS and ec agree shortwave ridging will push 
back into the region early to middle next week. Probability of precipitation were trended 
downward during this period...but did not go completely dry just yet 
given uncertainty. Another front may push into the region late in 
the week so probability of precipitation were trended back upwards towards day 7. /Neuman 




&& 




Aviation...offshore winds along the coast have weakened over 
kast...which has allowed fog to develop at the taf site dropping 
visible to IFR/LIFR. Winds don't look to increase at this site until 
later this morning so have added fog to the taf through middle- 
morning. Konp has offshore winds still...which will keep this site 
VFR through tonight. Shortwave trough moving across the area is 
keeping the inversion from setting up over the inland sites. This 
is keeping widespread dense fog from developing. Expect kttd to 
remain VFR as east winds continue out of The Gorge through 
tomorrow night. Patchy fog is being observed over the rest of the 
north Willamette Valley...as khio is occasionally dropping to 
IFR/LIFR. This could spread to pdx later this morning as the 
shortwave moves off to the east...but thinking more that kpdx will 
stay VFR through today. Further south...fog has developed around 
keug...bringing ceilings and visible down to LIFR. This should continue 
until it starts to lift early this afternoon. Ksle has been under 
a stratus deck around fl010...which has lifted a bit over the last 
couple hours and started to break up around fl015. Clearing will 
allow for fog to spread northward from keug... bringing ksle down 
to IFR/LIFR by around 15z this morning. This should burn off by 
late this morning. All sites should improve to VFR by this 
afternoon. 


Kpdx and approaches...VFR conditions are expected through 
today...with a chance of patchy fog around 14-17z bringing ceilings 
and visible down to IFR. If IFR conditions do develop...ceilings and visible 
should improve back to VFR by 17-18z and stay VFR through this 
afternoon. East winds out of The Gorge are expected to reach kpdx 
by 18z and persist through tonight...which should keep conditions 
VFR through tonight. -McCoy 




&& 




Marine...high pressure remains over the waters today and Friday. 
The next frontal system looks to move through Saturday night 
through Sunday morning. Models have increased winds a bit in this 
system as it moves through the waters...now forecasting marginal 
Small Craft Advisory winds. Will continue to monitor this as it 
gets closer. With increased winds...seas still only get up to 
around 9 feet...but any more increase in winds could bring seas up 
over 10 feet. As of now...seas are not forecast to reach over 10 feet 
through the weekend. A more active weather pattern appears 
possible to set up for next week...starting with this system late 
Saturday/early Sunday. Confidence in the details is low at this 
time. -McCoy
