NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
249 PM PDT Thursday Jul 24 2014 


Synopsis...the upper level low that brought abundant rain to 
southwest Washington and northwest Oregon the past two days has moved 
well east of the area this afternoon with continued onshore flow but 
decreasing showers. A weak upper ridge will begin moving into the 
area through tonight and Friday in its wake...with more afternoon 
sunshine and gradual warming on Friday. The upper ridge will amplify 
over the Pacific northwest Saturday and Sunday for more sunshine and 
significantly warming temperatures...and with less low clouds. An 
upper level ridge will remain inland over the northwest U.S. Through 
the middle of next week with southwest flow aloft but high 500 mb 
heights...for some marine influence mainly near the coast...and a few 
thunderstorms possibly brushing the Oregon Cascade crest at 
times...and continued warm weather inland. 
&& 


Short term...the low that had plagued southwest Washington and 
northwest Oregon the past two days with copious rainfall has moved 
east of the Cascades in Washington this afternoon. Significant 
onshore flow continues in its wake in the light westerly flow aloft. 
There are a few showers remaining mainly Tillamook to Vancouver 
northward...but these should decrease early this evening. There are a 
lot of clouds over southwest Washington and northwest Oregon this 
afternoon...and plenty upstream over the northeast Pacific that will 
advect in overnight tonight. I think the best chance for much 
clearing this evening will be south Lane County...but some clouds may 
filter in overnight down there as well. 


The models really do not show much if any upper ridging tonight... 
with the upper flow even slightly cyclonic at 12z Friday. Thus expect 
fairly decent low cloud coverage through tonight and into Friday 
morning across our forecast area. There is a weak disturbance around 
50n/130w this afternoon that may be the feature developing some 
patchy quantitative precipitation forecast along the north coast forecast zones early Friday...and is 
also probably part of why the low clouds will be rather solid tonight 
into Friday. So will leave the chance of sprinkles and drizzle in for 
later tonight and Friday morning near the north coast and coastal 
mountains. 


500 mb heights do begin to build a bit Friday so we should see more 
sunshine develop Friday afternoon than we have seen in several days. 
Temperatures inland should push into the upper 70s to near 80. Clouds on the 
north coast may again tend to hang on for a while in the afternoon 
due to the weak disturbance that causes the patchy light morning 
precipitation. 


The upper ridge amplifies in earnest Friday night and especially 
Saturday...with 500 mb heights into the lower to middle 580s by Saturday 
afternoon. After some brief morning low clouds inland along the 
Columbia River...look for plenty of sunshine and inland temperatures into 
the middle 80s on Saturday. There is not much change on Sunday... except 
temperatures inland may get closer to 90. The models show a weak disturbance 
lifting up into central Oregon from the southwest on Sunday that 
might brush our Oregon Cascade crest area with an isolated 
thunderstorm or two Sunday afternoon and evening. Tolleson 


Long term....a large upper-level ridge is forecast to be positioned 
over the Rocky Mountains...putting our region under southwesterly 
flow aloft next week. Several weak shortwaves are forecast up the 
ridge near our region.Most of these look like they will miss our 
area...but a chance for some scattered thunderstorms are possible 
along the Cascade crest Wednesday and Thursday. The southwesterly 
flow and sunny afternoons will keep our temperatures above normal. 
-McCoy 
&& 


Aviation...mostly VFR conditions now in control this afternoon... 
except for some MVFR ceilings along the S Washington and north or coast which should 
lift over the next couple of hours. Middle level clouds over the region on 
the latest Sat imagery should scatter somewhat this afternoon and 
this evening. But with northwest onshore flow now in place across the 
region...expect ceilings to lower back down to MVFR over the north coast 
overnight...and try to push up the lower Columbia into the North Valley. 
A high MVFR deck may also try to form along the Cascade foothills and 
back build into kttd and kpdx after 12z Friday. Some low stratus or 
patchy fog is a possibility along the central or coast 
overnight...where light offshore drift may develop. Conditions should 
return to widespread VFR by 17z to 19z Friday. 


Kpdx and approaches...mostly VFR conditions today. The only exception 
may be a brief period of MVFR ceilings through 18z in a passing shower. 
Clouds breaking up significantly late this afternoon and this 
evening. Pyle 
&& 


Marine...low pressure has moved inland and northwest flow less than 15 knots is 
now in control over the coastal waters. Seas remain a bit on the 
choppy side with periods of 8 to 9 second...but wave heights have 
subsided a little today and currently sit in the 6 to 8 feet range. 
Expect seas to continue gradually diminishing...reaching 4 to 5 feet by 
late evening. 


High pressure will begin to build over NE Pacific tonight and Friday...with 
thermal low pressure building over northwest calif. This will bring a more 
typical summertime pattern of gusty northerly winds...and potentially 
steep seas...especially S of Newport. Winds will start to increase 
Friday afternoon and evening...possibly reaching low end Small Craft 
Advisory speeds over the central or waters. The surface pressure gradient 
will then strengthen over the weekend into early next week...with 
solid Small Craft Advisory winds expected by sun and continuing 
through much of next week. 


A strong Ebb will bring choppy conditions on the Columbia River bar 
during the Ebb around 430 am Friday morning. Pyle 
&& 


Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...Small Craft Advisory for rough Columbia River bar from 
3 am to 6 am PDT Friday.
