NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
856 PM PDT Friday Oct 24 2014 


Synopsis...a deepening low pressure area well off the northern 
California waters this afternoon will move north to northeast tonight 
and Saturday. Expect a brief period of strong wind behind the low 
pressure area late Saturday afternoon through middle-evening 
..primarily along the central Oregon coast and in the interior 
valleys. An upper level trough over the region Sunday will continue 
shower activity. There will be a short drying period Monday... 
followed by another system Tuesday. The Tuesday system could bring 
another round of significant rainfall to the forecast area. 


&& 


Short term...a warm front is quickly lifting northward this evening 
and the main rain band is now mostly north of the Columbia River. I 
say mostly...because the front is beginning to tilt from SW to NE as 
the surface cold front approaches from the SW...causing the rain to 
persist over the north coast...north of Cannon Beach. The warm front 
should be completely north of the Portland forecast area around 
midnight tonight...but rain from the cold front will already be 
pushing onshore. 


Satellite imagery shows the upper trough offshore streching vertically 
suggesting that the trough may split as the previous NAM models were 
showing. There was fair uncertainty with the winds of this forecast 
before as the NAM was the outlier...but now it appears that the NAM 
may be the GFS and European model (ecmwf). Have updated the winds to 
trend towards the 00z NAM which has increased the winds a tad from 
the previous forecast. 


The winds along the coast will flirting with warning criteria 
Saturday afternoon...and the valley winds will be near advisory 
criteria. Would like to see the 00z GFS before issuing any headlines 
now...since there is such a large discrepancy in the position of the 
surface low between the 00 NAM and the 18z GFS. If the GFS comes more 
in line with the NAM than forecast confidence will strengthen...and 
there may be the need for some wind products with the morning 
forecast package. 


Back to rain...the rain with a cold front will move onshore around 
midnight tonight. Depending on how the trough splits there may be 
some areas along the coast that will be slower to see the rain than 
others. Leaned towards the NAM which shows the central Oregon coast 
seeing the rain first. Rain should be over the entire forecast area 
by Saturday afternoon. The front will move over the Cascades Saturday 
evening with abundant showers filling in behind it...over the coast 
to the Willamette Valley. Generally expect around an inch of rain 
along the coast...Coast Range and the SW Washington Cascades from 
Saturday morning through Saturday evening...with around 0.4 inch for 
the Willamette Valley and around 0.6 inch for the Oregon Cascades and 
Cascade foothills. 


An upper trough will swing through behind the front and maintain 
showers...as snow levels lower to just above the Cascade passes. 
This trough is fairly cool with modeled upper level temperatures 
around -25c. Modeled lapse rates around 7c/km...and negative lifted indices 
indicate that thunderstorms may develop Sunday afternoon. NAM shows 
the main instability near the coast but westerly flow may carry any 
storms that form westward. Have added a slight chance of 
thunderstorms for all areas west of the Cascades Sunday afternoon and 
evening. Expect local 2 to 4 inches of snow above 4500 feet. 


The trough pushes east Sunday night and there may be a brief break in 
rain Monday before the next moist front arrives Monday night. Tj 


Long term...the long term starts out wet with the next system moving 
into the forecast area Monday night. This system contains the remnants 
of Hurricane Ana...that skirted Hawaii last week. Models may be 
under doing the potential with this one. A strong jet 
stream will remain directed at Washington and northern Oregon through Tuesday night. 
Models show large variations beginning Wednesday...but expect the active 
pattern to continue. The European model (ecmwf) and GFS show a trend toward drier 
conditions late next week as a deep low in the Gulf of Alaska 
amplifies the downstream ridge over the intermountain west. Weishaar 


&& 


Aviation...rain has moved north faster than model solutions have 
shown for this evening...with some lingering showers with the warm 
front over the SW Washington and far northwest Oregon coast. Expect 
mostly VFR conditions to prevail tonight before the associated 
cold front approaches the region midday Sat. IFR/LIFR fog or low 
stratus will impact the central and southern Willamette Valley 
through at least 06-08z Sat...and locally in the north Willamette 
Valley. Rain returns to the coast between 12-14z Sat...and inland 
between 14-16z Sat. Gusty south winds will also impact the area 
after 14z Sat...strongest gusts in the afternoon and evening. 


Kpdx and approaches...VFR next 24 hours...except for a chance for 
brief MVFR fog or low stratus from 08-12z Sat. Rain and gusty 
south winds with gusts 25-30 knots possible are expected after 14-16z 
Sat...with strongest wind gusts in the afternoon and evening. /27 


&& 


Marine...a deepening low pressure system will approach from the SW 
late tonight and move through the coastal waters on Sat before 
moving inland late Sat night. Strong gale force winds are 
expected to start late tonight in the central or waters and last 
through Sat evening. In the northern or and souther Washington 
waters...expect gale conditions to begin early Sat morning and 
continue through Sat night. Steep seas are expected with the gales 
with wave heights peaking at around 15 feet Sat evening. 


As the low moves inland...winds will become west and decrease with 
seas lowering to around 7 to 9 feet as high pressure builds into the Pacific 
northwest. Another shortwave expected to approach the region early next 
week with seas of 10 to 12 feet possible. /64

Pqr watches/warnings/advisories...

waters from Cape Shoalwater Washington to Cascade Head or out 60 nm.
