NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
916 PM PDT Monday Aug 3 2015 


Synopsis...the upper level disturbance which grazed the Lane County 
Cascades with a couple thunderstorms is now moving into central 
Oregon...and will continue northeast overnight. Meanwhile a dry cold 
front is pushing down the Washington coast. This front will move 
across the forecast area tonight and Tuesday...ushering in stronger 
onshore flow for more night and morning low clouds and cooler 
temperatures...while keeping convection east of the area. After a brief 
warmup late in the week...another upper trough is forecast to develop 
along the coast next weekend into early the following week. 


&& 


Short term...a slow moving upper level disturbance coupled with some 
residual instability to produce some strong thunderstorms over 
south-central Oregon this afternoon...grazing Willamette Pass as they 
built northward along the Cascade crest. Lightning detection suggests 
only a few strikes actually occurred in our County Warning Area...with the bulk of 
the activity to the south and east of Willamette Pass. The main upper 
disturbance associated with this activity is now moving into central 
Oregon...and will continue northeast overnight...ending the threat 
for our district. 


The next feature to keep an eye on is actually difficult to discern 
on earlier visible and now infrared satellite imagery...but is more 
apparent on water vapor imagery. A dry cold front is pushing south 
along the Washington coast this evening...and should reach the mouth of the 
Columbia by midnight. The associated upper trough will settle into 
the Pacific northwest Tuesday/Wednesday for greater onshore flow and cooler temperatures as 500 
mb heights fall into the upper 570s. Stronger onshore flow may push 
more low cloudiness up the Columbia and into the pdx metropolitan tonight/ 
Tuesday morning...but there is some uncertainty as significant mixing and 
clearing of the marine layer has developed behind the front. Will 
stick with the current forecast of low clouds re-forming along the 
coast later tonight and spreading inland Tuesday morning as the boundary 
layer cools...especially considering how insistent model guidance is 
in bringing the stratus back. 


The upper trough to our north will linger through Wednesday with more 
northwest onshore flow and more morning low clouds especially 
north...possibly even working their way more southward in the 
Willamette Valley than on Tuesday. The models show a weak piece of 
energy rotating around the base of the upper trough and through 
western Washington late Tuesday night and Wednesday. The models 
support our current forecast of some drizzle on the north coast. 
There is a small possibility of some light precipitation reaching the 
north interior zones Wednesday either due to morning drizzle or 
isolated afternoon showers as the marine layer mixes into a 
stratocumulus deck. Temperatures inland in the north Wednesday will likely 
be 75 to 80 with 80 to 85 near Eugene. This will be the coolest day 
of the work week. 


The upper trough to our north moves east Wednesday night and 
Thursday. This will allow Thursday to be a warmer day with more 
sunshine than the previous two days...with the morning low clouds 
mainly north and clearing earlier than on Tuesday or Wednesday. 
Weagle/Tolleson 


Long term...broad upper-level trough and continued onshore flow 
should keep temperatures out of the 90s late this week into the 
weekend...but weakening onshore flow and winds becoming more 
southerly on Friday will allow temperatures to be a bit warmer on 
Friday than earlier in the week. Southerly flow also introduces a 
chance for thunderstorms in the Oregon Cascades...mainly along the 
crest. The shift to more southerly winds occurs ahead of a upper 
level low digging down out of Alaska over the weekend... bringing a 
chance for showers Saturday and Sunday. There is some disagreement 
between the models on timing and amount of rain with of this 
system...creating uncertainty which should become resolved as we 
approach this weekend. Have kept temperatures a bit closer to 
climatology on Saturday and Sunday...but if system plays out as 
forecast right now temperatures will likely be a bit cooler than 
currently forecast. -McCoy 


&& 


Aviation...a stable low level northwesterly flow pattern will 
bring MVFR to high end IFR conditions to the coast overnight and 
Tuesday morning with mainly VFR conditions inland. Given current 
stratus coverage offshore is modest at best...confidence is not 
all that high it will be able to make it into the Portland metropolitan 
tafs. Kpdx and kttd will be susceptible to MVFR conditions 
primarily between 13z and 17z Tuesday. Khio...ksle and keug seem 
more than likely to remain VFR through 06z Wednesday. 


MVFR stratus remains along the north coast...with VFR ceilings over 
the central coast. Ceilings over the north coast look to scatter out 
briefly this afternoon...but expect widespread MVFR ceilings to 
return this evening. IFR ceilings and visibility possible after 06z over the 
central coast. A brief period of VFR ceilings possible Tuesday afternoon. 


Kpdx and approaches...a stable northwesterly flow pattern will 
bring primarily VFR conditions through 06z Wednesday. There is a 
chance a brief period of MVFR ceilings will develop over the terminal 
Tuesday morning...most likely between 13z and 17z Tuesday. 
Given the minimal amount of stratus offshore...confidence has 
lowered that it will be able to push inland to pdx. /Neuman 


&& 


Marine...high pressure will continue over the northeast Pacific 
and continue our typical summertime pattern of northerly winds 
along the coast with occasional steeper wind driven seas from time 
to time this week. Winds and seas will generally be strongest 
across the central Oregon waters for the next several days. 


The first round of winds and higher seas should arrive Tuesday 
afternoon and evening. Although steep and hazardous seas will be 
marginal...opted to issue an advisory for this threat for the 
central Oregon waters given model guidance and bias. 


The next major uptick in winds and seas will likely arrive 
Thursday afternoon and evening as thermal low pressure temporarily 
strengthens over California and we will likely need another round 
of small craft advisories for the central Oregon waters. 


An upper level trough should settle into the Pacific northwest 
over the weekend...and a weak front may briefly turn winds 
southerly...but winds look to remain relatively benign. 
Otherwise...we may see northerly winds strengthen as thermal low 
pressure over California returns late in the weekend into early 
next week. /Neuman
