NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
840 PM PDT sun Oct 19 2014 


Synopsis...a long wave trough is anchored in the eastern Pacific 
and will send a series of systems across the Pacific northwest 
through the week. The first front was moving onshore this evening 
and will move through southwest Washington and northwest Oregon the 
remainder of tonight and Monday morning. The associated upper trough 
will lift northeast as it weakens Monday night into Tuesday. The 
next rather strong and quite wet front will approach the coast late 
Tuesday and move through the forecast area Tuesday night into 
Wednesday...lingering into Thursday. Another front is expected by 
the weekend. Expect blustery conditions at times near the coast. 
Snow levels will remain fairly high in the Cascades. 
&& 


Short term...a long wave trough has become anchored in the eastern 
Pacific and will continue there through the week...continuing the 
Fall like weather over southwest Washington and northwest Oregon. The 
first fairly strong front was north south oriented along the coast 
and just beginning to move onshore this evening. The front will 
slowly move inland and through the remainder of the forecast area 
overnight tonight and Monday morning for a good dose of rain. 


The associated trailing upper trough is forecast to lift out to the 
northeast Monday night and early Tuesday...with the main energy 
moving to the south and onshore into California. Expect some showers 
especially near the coast and over the higher terrain...but the main 
cold pool aloft and instability look to be moving to our south. Will 
keep some thunder over the waters and near the coast...but inland is 
looking less likely at this point. 


The next front is approaching the north coast later Tuesday and 
moving slowly south through the forecast area Tuesday night and 
Wednesday with another bout of fairly heavy rain. This front looks 
even more moist than the current one...with model precipitable water 
values up near 1.3 inches and strong 850 mb inflow winds. 
Fortunately...at this point the front does not seem to stall and 
generally pushes through our area somewhat steadily though still 
slowly. This system does need to be carefully watched as there could 
be sharp rises on some rivers...including some of our flashier 
rivers such as the Grays River in southwest Washington. 


The models vary some on the strength of the passing low pressure 
center Tuesday night and Wednesday...with the GFS the strongest and 
the European model (ecmwf) the weakest. If the GFS is closer to verifying...then we 
could see our first Headland coastal high wind event of the fall. In 
any event gales look pretty certain over the coastal waters. Tolleson 


Long term...Wednesday night through Sunday. Shortwaves continue to 
be generated off persistent longwave troughing over the northern 
Pacific...continuing to generate these frontal systems that move 
through approximately every other day.This keeps rain in the 
forecast...because as one moves off to the east...another system 
approaches right behind it. This pattern appears as if it will 
persist through Sunday...though model solutions diverge in timing 
and evolution of these systems. Model agreement is fairly poor after 
Thursday...so confidence is fairly low through the extended. Both 
the European model (ecmwf) and GFS...though...hint at a slight increase in 
temperatures over the weekend...as broad thermal ridging builds over 
the Pacific northwest. -McCoy 
&& 


Aviation...VFR across much of the area tonight ahead of a frontal 
system moving into the region. Front has slowed considerably this 
evening and is presently near the coast...where gusty S winds to 25 
knots and VFR ceilings around 4000 feet along with a scattered deck around 
3000 feet have developed along with rain starting to reach the coastal 
terminals. As front continues move into the interior...rain and MVFR 
conditions will spread inland after 06z with rain moderate at times 
with potential for local IFR visibilities for most of the night. Showery 
conditions and MVFR with patchy IFR ceilings developing 12z through at 
least 18z Monday. Possibility of thunderstorms developing along the 
coastal areas late tonight and tomorrow. 


Kpdx and approaches...expect increasing clouds tonight with ceilings 
developing around 4000 feet by 07z. Periods of moderate rain continue 
overnight with ceilings lowering to around 2000 feet along with decreasing 
visibilities possible from 12z through 18z. Ceilings should lift back to VFR 
around midday Monday with potential for brief MVFR reductions with 
showers continuing. Cullen 
&& 


Marine...little change in the big picture for the next several days 
as broad low pressure stays entrenched over the Gulf of Alaska. 
Expect multiple fronts and smaller scale low pressure systems to cross 
the waters this week. 


The first cold front has traversed the waters and is presently 
located just onshore. While wind gusts to 41 knots at buoy 46029 and 44 
knots at Garibaldi were recorded this evening...winds have eased as the 
front pushed onshore and with observations last hour considerably 
lower...feel comfortable to end the Gale Warning as of 8 PM. Gusts 
25-30 knots may continue for a few more hours...so have hoisted a Small 
Craft Advisory for winds for all waters through tonight. Winds will 
ease Monday morning and afternoon...but may see some gusts near 25 knots 
Monday evening and early Tuesday. Winds will again increase significantly 
late Tuesday into Wednesday...with another round of at least gale force winds 
likely...though details in the evolution of the track and intensity 
of this next front remains a low confidence forecast given 
considerable model uncertainty. 


Seas peaked around 14 feet this evening and will likely remain in the 
12-14 feet range through Monday night...and have issued a Small Craft 
Advisory for hazardous seas. Seas gradually ease a little late Monday or 
early Tuesday...but should again build a bit higher with the low pressure 
system and front arriving Tue/Wed. Thus...expect that seas likely 
remain at or above 10 feet through most if not all of this week.
