NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
900 PM PST Friday Feb 12 2016 


Synopsis...cooler air spilling in behind a cold front will 
eventually allow snow levels to lower below Cascade passes tonight 
and Saturday. A strong warm front will then spread steady rain into 
northwest Oregon and southwest Washington Saturday afternoon and 
evening with a period of heavy snow for the Cascades. However...snow 
levels will rise to well above the Cascade passes as periods of 
lighter rain fall on Sunday. Additional unsettled weather will 
produce more valley rain and mountain snow next week. 


&& 


Short term...by late evening cold front had pushed east across the 
Cascades. Still some showers showing up on radar...mainly 
orographically driven on the Cascades...the north Coast Range and 
Willapa Hills. The main shortwave wave trough axis was still jus off 
the Washington and north Oregon coast...adding some dynamic lift tonight as it 
moves across mainly the north part of the forecast area...so will need 
to keep some mention of showers overnight in the north interior in 
addition to coast and mountain locations. 


Remainder of short term discussion unchanged...a strong warm front 
will spread into the region late Saturday afternoon and produce an 
extended period of wet weather Saturday night and Sunday. Rainfall 
amounts of at least 1 to 3 inches appear likely in the Coast Range 
and Cascades with a quarter to one inch of rain in the lower 
Columbia River and Willamette valleys. The highest rainfall amounts 
should be focused over our more northern zones. Snow levels will 
likely start off around 4000 feet Saturday afternoon and 
evening...particularly across the South Washington Cascades and near 
Mount Hood before rising abruptly to 7000 feet or more for Sunday. 
Nonetheless...4 to 8 inches of snow appear likely...and perhaps even 
more in the South Washington Cascades...before the snow turns to 
rain. 


This weekends rain should come in two distinct surges. The first will 
arrive late Saturday afternoon/early evening and will likely be the 
strongest as 50 knots westerly 850mb winds enhance ivt values to 
something we typically see about once a year to once every other year 
in February. This surge of rain should result in many of our faster 
responding rivers to rise rapidly...particularly the Grays 
River...but main Stem river flooding is not anticipated. A secondary 
surge of rain should arrive Sunday morning as a weaker warm front 
pushes northeastward across the region. As isentropic lift weakens 
and westerly 850mb strengthens midday Sunday...expect precipitation 
to lighten...if not stop...in the Willamette Valley as a Coast Range 
rain shadow develops. 


Shortwave ridging should then slowly push into the region Sunday 
night and Monday so expect a general drying trend from southwest to 
northeast during this period with mild temperatures...ie high 
temperatures flirting with 60f...returning Monday. /Neuman 


Long term...no changes. Previous discussion follows. Monday night 
through Friday...shortwave ridging early in the week will once again 
give way to a more active weather pattern during the middle to 
latter half of next week. The remnants of an atmospheric river event 
may dip far enough south to bring some light rain to the region 
Tuesday...but confidence is low. Models have been in much better 
agreement that a shortwave trough will swing into the western United 
States and bring wet and cooler weather Wednesday into Thursday. An 
additional storm system appears possible towards the end of next 
week. Temperatures for the most part should remain near to above 
normal with any bouts of precipitation looking to remain light 
enough that we do not foresee any major hydrologic issues in the 
next week. Ab/neuman 


&& 


Aviation...upper level low pressure moving onshore will bring a round 
of showers overnight into Sat am...mainly for the coast and 
higher terrain. Expect a mix of VFR and MVFR ceilings at the coast. Rain 
shadowing may keep the valley mostly dry with VFR conditions for 
much of the night. Then expect some MVFR ceilings to develop early Sat 
am...between 12z and 15z. Expect conditions to improve to VFR for 
the late morning and afternoon inland from roughly ksle southward. 
Elsewhere...MVFR may linger through the day. Expect conditions to 
deteriorate further with increasing rain from northwest to southeast Sat 
afternoon and evening as a warm front approaches. 


Kpdx and approaches...mostly VFR with the potential for a passing 
shower overnight. Expect MVFR ceilings to develop by around 12z to 15z 
Sat...with MVFR potentially lingering through the day. Ceilings lower 
further and rain increases Sat afternoon and evening. Pyle 


&& 


Marine...a long period northwest swell will maintain 11 to 13 feet seas 
through Saturday night. The seas will subside to around 10 feet on 
Sunday. A surface trough moving through the waters will increase 
winds a bit overnight. The models suggest that gusts could reach 
25 knots beyond 10 nm...mainly north of Cascade Head. Have decided to 
issue a short Small Craft Advisory for winds for the northern 
outer waters. 


Winds will come up further with the next system with at least 
small craft winds Saturday afternoon through late Saturday night. 
Gale force gusts are possible...and a gale watch is in effect for 
this time period. There is greater forecast confidence for gales 
north of Cascade Head. Tj/pyle 


&& 


Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...gale watch from Saturday afternoon through Saturday evening for 
coastal waters from Cape Shoalwater Washington to Florence or out 60 nm. 


Small Craft Advisory for winds until 4 am PST Saturday for 
waters from Cape Shoalwater Washington to Cascade Head or from 10 
to 60 nm. 


Small Craft Advisory for hazardous seas until 2 PM PST Saturday 
for coastal waters from Cape Shoalwater Washington to Florence or out 60 nm. 


Small Craft Advisory for rough Columbia River bar until 10 PM PST Saturday.
