NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
241 am PST sun Nov 23 2014 


Synopsis...after a brief lull in showers early this morning...the 
next front will bring rain and mountain snow to southwest Washington 
midday today...moving south through this afternoon. Snow levels will 
remain near the Cascade passes...but accumulations are expected to be 
minor for the northern Oregon passes. A flat upper ridge will build 
into California and Oregon Monday and Tuesday...but should remain 
weak enough for systems to clip our northern zones with occasional 
wet weather. Valley inversions will likely build in the central and 
south Willamette Valley...with fog possibly becoming more persistent 
by the middle of next week. Another organized frontal system may 
bring more rain to the region for Thanksgiving weekend. 


&& 


Short term...today through Wednesday...light scattered showers 
continue to push across the region this morning. Surface observations 
are showing between 0.01-0.05 inches of precipitation in the past 3 
hours across the Coast Range and inland valleys...with higher amounts 
over the Cascades. The precipitation associated with the next frontal band 
is already popping up on katx and klgx radars in Washington...with 
embedded lightning as the cold front approaches the coastal waters. 


The 06z GFS and NAM are showing decent cape values for over the 
coastal waters...and given the convective nature of the showers as 
seen on radar so far this morning...cannot rule out the possibility 
of an isolated thunderstorm or two over our SW Washington/northwest Oregon 
coastal waters. 


There has also been enough clearing this morning to maintain some 
localized patchy fog over the inland valleys. Expect any lingering 
fog to dissipate later this morning with the increasing rain as the 
cold front approaches the region. Much of the energy will be focused 
further north of our forecast area...with the exception of areas 
north of the Columbia River and in particular the SW Washington 
Cascades. 06z NAM and GFS show a bullseye of abundant precipitation 
over the SW Washington Cascades this morning and afternoon...before 
models have the front sag further southeast. With snow levels still 
around 4000 feet...still expecting about 6-9 inches of accumulating 
snow in a 12 hour period. Models are in good agreement advisory level 
snow accumulations will impact the SW Washington Cascades... while 
1-3 inches of snow could still fall over the northwest Oregon Cascades as 
the cold front sags south later today. Areas further south will see 
much less. 


Elsewhere...expect cool and rainy conditions through this evening. 
Total precipitation amounts look rather marginal...with most locations 
topping out around 0.15 inches of rain in a 24 hour period. Lower 
precipitation amounts are expected the further south you go. 


High pressure begins to build over the eastern Pacific late tonight 
into Monday...which should keep the region fairly dry but cloudy. But 
the threat for valley fog increases...especially for the central and 
south Willamette Valley as well as the central coast. Models have 
been consistent in showing a few disturbances riding over the ridge 
and bringing some precipitation mainly to the far northern forecast zones by 
Monday evening. Expect this pattern of northern showers with southern 
valley and coastal fog to continue through Wednesday. /27 


Long term...Wednesday night through Sunday...overall models are 
attempting to flatten the upper level ridge late Wednesday. But once 
we get to Thanksgiving morning...model solutions vary concerning the 
next Pacific frontal system approaching the region Thanksgiving day. 
The 06z GFS shows a rather well-organized frontal band reaching the 
SW Washington/northwest Oregon coast in the morning...with rain spreading 
inland by the afternoon...right in time for Thanksgiving dinner. Will 
have to see what the 12z European model (ecmwf) does with this system...and whether or 
not it maintains its lighter rain/ridgy solution. A much 
stronger and wetter system looks to move in over the weekend which 
could pose a threat to travelers returning after the Thanksgiving 
Holiday. Details at this point are still unknown and will be refined 
with future updates. The good news is that temperatures in the 
extended will be at or above seasonal normals. /64/27 


&& 


Aviation...a Post frontal showery air mass will lead to VFR 
conditions at most taf sites across northwest Oregon and southwest 
Washington early this morning. However...occasionally enough 
clearing will occur for scattered taf sites to deteriorate into 
MVFR and IFR conditions. Conditions should then subsequently 
improve as the next shower moves overhead. 


A front off the Washington coast is producing lightning and a 
narrow band of heavy rain. This front will weaken as it pushes 
into northwest Oregon...but it may allow for a period of MVFR 
conditions at kast and the kpdx metropolitan taf sites towards midday. 
There is a chance MVFR conditions may persist towards 12z Monday 
for the Portland metropolitan taf sites. Farther south where clearing 
this evening will be more likely to occur...IFR conditions may 
develop at keug...ksle and even khio towards 12z Monday. 


Kpdx and approaches...a Post frontal showery air mass will lead 
to predominantly VFR conditions today. A band of rain associated 
with a dying front may temporarily reduce ceilings into MVFR. There is 
a chance these conditions could persist well into Sunday 
night...or perhaps deteriorate into high end IFR conditions...but 
confidence in these details is low at this point. /Neuman 


&& 


Marine...a front off the Washington coast is producing a narrow 
band of thunderstorms that will push towards the South Washington 
coastal waters early this morning. Given the unstable airmass in 
place...there is some concern a burst of low end gale force wind 
gusts of 35 knots may surface across the northern waters this morning 
as this band of thunderstorms pushes through. Continued the Small 
Craft Advisory for now...but will monitor trends upstream to see 
if a short fused Gale Warning is necessary. Otherwise...expect 
gusty winds to taper off this afternoon...and seas to peak in the 
middle teens before decreasing tonight into Monday. 


A weak front will push into the waters late Monday...but aside 
from some Small Craft Advisory level wind gusts of 25 knots...not 
expecting much impact. Winds may stay a bit gustier across the 
northern waters early to middle week before a slow moving low pressure 
system impacts the waters middle to late next week. Low end gale force 
wind gusts might be squeezed out of this system at some point...but 
the scenario does not look all that promising for a solid gale 
force or higher wind event for the waters. /Neuman 


&& 


Pqr watches/warnings/advisories... 
or...none. 
Washington...Winter Weather Advisory from 7 am this morning to 10 PM PST 
this evening for South Washington Cascades. 


Pz...Small Craft Advisory for winds until 3 PM PST this afternoon 
for coastal waters from Cape Shoalwater Washington to Cascade Head or 
out 60 nm. 


Small Craft Advisory for hazardous seas until 9 am PST Monday 
for coastal waters from Cape Shoalwater Washington to Florence or out 
60 nm. 


Small Craft Advisory for rough Columbia River bar until 9 am 
PST Monday.
