NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
932 am PDT Friday Aug 22 2014 


Synopsis...upper level low pressure center continues to slide east 
of the area today. There will be enough instability on the west side 
of this low to bring a slight threat for thunderstorms for the South 
Washington Cascades and extreme north Oregon Cascades this afternoon. 
Northerly flow aloft continues over the weekend maintaining onshore 
low-level flow and near to slightly above normal high temperatures. 
High pressure strengthens just offshore bringing a warm up for the 
first half of next week. 


&& 


Update...remnants of an old front has resulted in a variety of 
clouds across northwest Oregon this morning...and some spotty drizzle. Radar 
imagery shows light drizzle moving through the Willamette 
Valley...currently between Hillsboro and Salem. This drizzle looks to 
be moving south around 8 miles per hour. There has not been any known 
accumulation...but a trace of precipitation was measured at 
Hillsboro. 


High pressure is building over the area and visible satellite imagery 
shows northerly flow clearing skies from north to south. Have 
adjusted todays sky forecast to increase sunshine in most areas. 
There is still a slight threat for thunderstorms this afternoon for 
the Washington and extreme northern Oregon Cascades... mainly around 
Mount Adams...but the threat looks really low. Have limited showers 
to scattered for the Cascades and Cascade foothills for this 
afternoon and evening. Tj 


Previous short term...tonight through Sunday...low pressure will 
continue to develop across the interior pacnw today resulting in a 
challenging forecast for the next 24 hours. A closed low center is 
beginning to wind up under cyclogenesis. The complex dynamics with 
the developing low were able to wring out some drizzle along the 
coast with both Astoria and Newport recording at least an hour of 
precipitation. North answer east of the developing low center...a 
significant amount of nocturnal convection thus far has generated 
moisture which will get wrapped around to moisten up the western 
fringes of the low. Expect the northeastern 1/3rd of the County Warning Area will be 
impacted by this moisture in varying forms. 


The most significant threat will be for thunderstorms. Still feel 
most activity will remain confined to areas northeast of the 
Portland metropolitan and closer to Montana Adams. Both the NAM and GFS agree 
there will be sufficient surface heating and moisture to create deep 
convection and thunderstorms. Further south and west the models have 
limited agreement. The big issue will be surface dew points. The NAM 
as of the last few years has commonly produce too much surface 
moisture and thus dew points too high by a few degrees. 
Conversely...the GFS tends to run a few degrees to dry. 


The 00z model runs are holding true to expectations at least through 
the 09z hour with reality lying somewhere in between but a slight bit 
closer to the GFS. Determining what reality will bring is where the 
specific challenge lies. Skin temperatures from both model forecast 
soundings are also appearing to be too cool as is often the case. 
Based on the raw model sounding data...the GFS does not show 
convection very far away from the Cascades while the NAM brings a 
threat to the metropolitan and as far west as about Kelso/Longview. 
Ultimately landed on about a 60/40 blend of surface dew points 
favoring the GFS. This combined with manual temperature adjustments 
to the sounding surface conditions produced a first estimate of 
thunderstorms with confidence and isolated coverage across the bulk 
of Skamania County...lower confidence slight chance coverage to the 
eastern 1/4 of Cowlitz County stretching south to include The Gorge 
and areas east of Sandy around Montana Hood...and then a threat of showers 
only mainly north of the Columbia River. Obviously we are walking a 
very fine line today between nothing happening across our northern 
tier and a decent coverage of thunderstorms so felt using probability 
in the truest sense was the most prudent course of action today 
noting that a 20 percent chance really means 80 percent of the time 
it will not happen. Did feel reasonably confident that temperatures 
need to get close to their forecasted highs today to trigger 
convection in any form. Thus would not expect to see much rain 
forming until after 2 PM. Also would not expect it to last very long 
into the evening but did not have as much confidence to shut off the 
threat by 8 PM so left it in place for the entire evening. 


The upper low will slowly move east overnight while an upper ridge 
builds offshore. This will maintain a typically drier northwesterly 
to northerly flow and bring uneventful weather for the rest of the 
weekend aside from clouds at the coast and perhaps some brief 
morning clouds inland. Temperatures near or slightly above 
normal will gradually warm further. /Jbonk 


Long term...Sunday through Thursday...no changes. Previous 
discussion follows. Upper level ridging will move onshore allowing 
temperatures to increase slightly above seasonal norms for the 
beginning part of next week. As the ridge begins to breakdown 
and become more zonal we will see an increase in low and middle level 
moisture. This will provide for an increase in cloud cover for the 
latter part of next week. Do not expect any precipitation in the 
near future. /64 


&& 


Aviation...coastal stratus producing IFR conditions along the 
coast should give way to VFR conditions this afternoon. Continued 
onshore flow should produce another round of IFR conditions along 
the coast tonight and into Saturday morning. Further 
inland...north to northeasterly winds should be strong enough to 
keep conditions VFR through 18z Saturday. 


Kpdx and approaches...high pressure and increasing northeasterly 
flow should produce VFR conditions through 18z Saturday. /Neuman 


&& 


Marine...high pressure will continue over the northeast Pacific 
into the foreseeable future. However...thermal low pressure over 
California will shift more squarely over the coast Saturday and 
again early next week...in a pattern that has been relatively rare 
this Summer. This should produce widespread northerly winds of 25 
to 30kt especially across the central Oregon waters. With a 
westerly swell remaining 4 feet or less during this time...seas may 
also become wind dominated...I.E. Especially steep and hazardous 
across the central waters so a small craft for hazardous seas will 
be possible Saturday and again early next week. /Neuman
