NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
253 PM PDT sun Aug 2 2015 


Synopsis...as a strong positively tilted upper level ridge continues 
to move east today as an upper level low off the California coast 
continues to steer moisture and instability northward over western 
Oregon and into southwest Washington. This moisture and instability 
will continue tonight into Monday morning for a threat of some 
showers or thunderstorms. An upper level trough along the b.C. Coast 
will begin moving south toward the Pacific northwest later tonight 
and on Monday...and have an increasing impact over southwest 
Washington and northwest Oregon during the middle week period for cooler 
temperatures and more night and morning clouds. 
&& 


Short term...convective clouds have continued to increase from the 
south and southeast today as a steady stream of middle and higher level 
moisture spreads north from the sierras and from Nevada...being 
steered by an upper low located well off the California coast. The 
clouds have been thick enough to produce a few showers across the 
forecast area...and were thickest over the Coast Range this 
afternoon. Satellite imagery shows plenty of clouds upstream in 
northern California...the sierras...and northern Nevada that will 
continue to spread north overnight into Monday morning. This cloud 
cover is associated with an elongated area of vorticity that is 
forecast to move through our forecast area tonight and early Monday. 
The models show a decent jet segment associated with this feature as 
it moves through...giving support to the idea of elevated nocturnal 
convection continuing tonight into Monday morning. This is how the 
forecast has been trended over the last 24 to 36 hours. 


The short wave or vorticity lobe and moisture area will still be over 
the forecast area early Monday before moving east in the afternoon. 


Despite a rather warm air mass remaining over our area...the clouds 
have suppressed temperatures though the humidity has risen quite a 
bit when compared to the past couple of days. Unless more sunbreaks 
develop than are now expected...it looks as if we will have trouble 
reaching 90 degrees today...and so will end the heat advisory. 


By Monday an upper trough along the b.C. Coast will be sagging south 
along the coast toward the Pacific northwest. This will help turn the 
upper flow Monday afternoon to more southwesterly...and limit the 
thunderstorm potential later Monday to our southern Cascade areas and 
to especially near the crest. The upper trough will continue to sag 
south with more energy in Washington by Tuesday... with more westerly 
flow aloft over southwest Washington and northwest Oregon. 
Again...the main threat of thunder for our area will be near 
Willamette Pass later Tuesday...and even that is not certain. 


The marine layer was again shallow and confined to near the coast 
this morning. The marine layer will likely thicken some from the 
south along the coast tonight as the short wave lifts through... 
possibly trying to push into the coastal gaps by Monday morning... 
but inland coverage will be spotty. Expect better inland coverage of 
low clouds Tuesday morning and again Wednesday morning...especially 
north...with the increased westerly flow aloft and the proximity of 
the upper trough to our north. 


We will probably see more sunshine on Monday afternoon than this 
afternoon...but with a gradual cooling of the air mass. Temperatures will 
tend to be in the middle 80s to lower 90s...coolest north. Temperatures will be 
closer to normal Tuesday and Wednesday under the northwest onshore 
flow. Tolleson 


Long term...models continue to show a weak/flat upper level ridge 
moving through the region for the latter half of the workweek. With 
decreasing onshore flow we should see temperatures climb back into 
the middle 80s by Friday. Another upper level trough looks to approach 
from the northwest over the weekend. However...models continue to 
differ with regards to its timing and strength. Upper level flow 
should begin to turn to the southwest late Friday ahead of the 
trough...so will keep a slight chance of thunderstorms for the Oregon 
Cascades. As the base of the trough pushes inland we will see an 
increase in shower activity across the region. Based on some 
lingering instability and southwesterly flow aloft have added a 
slight chance of thunderstorms to the Cascades. Temperatures over the 
weekend look to fall back towards seasonal normals. /64 
&& 


Aviation...broad area of instability moving across the region from 
south to north. Mostly middle level showers at this point although there 
is thunderstorm action from about krbg to the south and well offshore 
at this hour. Expect the general threat for thunder to move north 
today through this evening and potentially overnight as a short wave 
moving north acts as a lifting trigger. In general...am expecting 
isolated coverage with little confidence in where those single storms 
will specifically develop and thus low confidence for taf inclusion 
at this time. Will continue to monitor and amend as conditions 
evolve. Regardless...could get some outflow gusts around 25 kts with 
an outside chance of 35 kts from the storms that do form. Do not 
expect much low cloud from these showers or storms and not any visibility 
reductions either. 


Will continue to see stratus impacts at the coast today and a bit 
longer than the past couple days. It has burned off at kast and south 
through ktmk but still appears to be in the vcty of konp where 
reductions recently occurred. Continuing to have a hard time 
following stratus movement via satellite as the advancing middle level 
clouds are obscuring. Have no reason to doubt low clouds will return 
tonight. /Jbonk 


Kpdx and approaches...VFR conditions. However...plenty of middle level 
clouds with the potential for a thunderstorm. Best timing will be 
from 23z through about 04z. /Jbonk 
&& 


Marine...little change to the overall surface pattern for the week 
ahead with north winds over the waters. Have cut back the coverage of the 
Small Craft Advisory for winds to cover just the northern outer 
waters. Models have picked up on current cloud cover over SW Oregon 
and northern California may inhibiting the strength of the land heating 
and thus the lighter winds overall. Still could see thunderstorms 
over the waters through the evening and possibly overnight hours as 
well. Dont feel like there will be a significant amount of 
thunderstorm coverage but could see some outflow gusts 25 to 30 knots 
under the strongest cells. 


Meanwhile...the persistent northerly winds are generating a steep 
fresh swell 5 to 6 feet at 7 to 9 seconds. Still am seeing occasional 
square seas out at buoy 89 when combined with the long period SW 
swell. They continue to be isolated and sporadic with focus toward 
the western boundary of our borders. As such...dropped the advisory 
for seas earlier today. Still fairly steep nonetheless. /Jbonk 


Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...Small Craft Advisory for winds until midnight PDT tonight for 
waters from Cape Shoalwater Washington to Cascade Head or from 10 
to 60 nm.
