NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland 
817 PM PDT Sat may 23 2015 


Synopsis...cloudy skies will persist through Sunday morning...with 
partial clearing in the afternoon. An upper level low will move over 
central and eastern Washington Monday. The main result will be 
continued moderate to strong onshore flow and plenty of clouds over 
the area...as well as local drizzle or light showers mainly in the 
late night and mornings. The central Washington low from Monday will 
move east enough around the middle week period to see more sunshine in 
the afternoon and evening hours with warming temperatures. 
&& 


Update...onshore flow and cloudy skies persist this evening and will 
continue through Sunday morning. Rain has ended over the Portland 
forecast area...but have kept a slight chance of rain for SW 
Washington Cascades where thunderstorms have been looming near by. 
The thunderstorms have remained east of the Cascades and are not 
expected to impact areas west of the Cascades tonight. 


Models show a better chance for some clearing Sunday afternoon with 
weak upper level ridging over the area and more northerly flow. Think 
strato cumulus may linger around..but there will be more pockets of 
sunshine. Another upper level low will move over the Pacific northwest 
Monday and Tuesday for more clouds and increased chances for showers tj 


Previous short term...water vapor satellite imagery clearly shows the 
system that was dropping south along the coast last night is already 
well south into northern California this afternoon. This system did 
reinforced the onshore flow...which is moderate to strong and thus 
the low clouds continue to appear on satellite as though they will 
have trouble breaking up at all today. As this system has moved so 
far south...the showers from last night and early today have waned 
considerably. Could still be some development in the higher Cascades 
later today...but even that is a bit doubtful. Current temperature trends 
suggest highs will top out most lower elevations areas west of the 
Cascades between 60 and 65...except 55 to 60 at the coast. 


There is another low centered along the central b.C. Coast that is 
forecast to drop south into southern b.C. Late tonight and Sunday and 
into central and eastern Washington Monday. This feature will also 
maintain/reinforce the onshore flow...as well as finally turn the 
winds aloft to a more west to northwesterly direction. There is still 
a risk of some patchy drizzle around early Sunday...but we may see a 
few thin spots in the clouds in the middle to late afternoon. On Monday 
there is a better chance of some drizzle or sprinkles around 
especially along the coast on in the northern inland areas including 
Portland. The position of the low inland over Washington on Monday 
suggests that clearing of the marine clouds west of the Cascades on 
Monday may be difficult again. However the increased westerly flow 
aloft both Sunday and Monday suggest that there should not be any 
thunderstorms over the area either. 


On Tuesday the upper low in central and eastern Washington drifts to 
near the Idaho border. Onshore flow continues to be strong...but it 
is possible that we get some late day sun breaks that could lead to 
some higher elevation showers in the Cascades while allowing temperatures to 
climb back to more seasonal values. Tolleson 


Long term...Tuesday night through Saturday...continued onshore flow 
behind the Monday system will keep cool cloudy weather through 
Wednesday. Most precipitation should stay up in the higher elevations 
of the Cascades. Brought temperatures back down some through the end of the 
week as models are now showing the region staying under weak onshore 
flow. Temperatures do warm some Thursday-Sat as shortwave ridging moves 
over the region. A thermal low to our south will set up a good 
pattern for dry weather for the Willamette Valley...with clearer 
skies in the afternoon...and afternoon showers and possibly 
thunderstorms in the Cascades. -McCoy 
&& 


Aviation...a mixture of MVFR to VFR with ceilings generally between 
2000-3500 feet will persist through tonight. Conditions inland will 
deteriorate towards prevailing MVFR this evening and continue 
through at least 15z-17z Sunday. Expect a mixture of IFR/MVFR 
ceilings along the coast through Sunday...with an increasing chance 
for IFR ceilings and visibility between 08z-16z Sunday. 


Kpdx and approaches...MVFR ceilings around 2000 feet will continue through 
at least 17z-19z Sunday. Should see brief VFR ceilings Sunday 
afternoon before MVFR ceilings return late Sunday. /27 


&& 


Marine...high pressure remains offshore with low pressure over the inland 
Pacific northwest for the next several days. This will continue to bring 
benign conditions to the waters with northwest winds generally below 
advisory criteria. There is a chance for some advisory gusts above 
21 knots Sun afternoon/evening south of Newport...but confidence is 
not high that it will come to fruition. Stronger winds off of the 
b.C. Coast are producing a fresh swell out of the northwest and will 
continue to bring choppy seas through at least Tuesday. /64
