NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
946 PM PST sun Nov 23 2014 


Synopsis...a frontal zone has stalled between Salem and Eugene this 
evening...and continues to bring valley rain and Cascade snow more or 
less along the Highway 20 corridor. This front will weaken overnight 
with precipitation decreasing. Weak high pressure will likely keep 
much of the forecast area dry Monday morning...but a warm front is 
expected to bring more rain with rising snow levels to the district 
by Monday evening. Another disturbance will likely ride along this 
front Tuesday...bringing more rain to southwest Washington while the 
central and southern Willamette Valley dry out. After a mainly dry 
day Wednesday...the next frontal system is expected to arrive 
Thanksgiving day followed by more unsettled weather through the 
Holiday weekend. 


&& 


Short term...tonight through Wednesday...krtx radar imagery 
continues to show a stalled frontal zone producing a persistent band 
of valley rain and Cascade snow from roughly Newport to Santiam 
Pass...along or just north of the Highway 20 corridor. Precipitation 
along this frontal zone was fairly heavy earlier this evening... 
dropping a quick 4-7 inches of snow earlier today and warranting a 
quick Snow Advisory for areas near Mount Hood. Valley rain was heavy 
at times as well...with a quick half inch of rain coming in a 1-2 
hour period and resulting in some minor urban flooding issues 
earlier this evening. Precipitation rates within the frontal band are not 
as impressive as they were a couple hours ago. The odot webcam at 
Santiam Pass showed a decent amount of snow falling...but roads were 
generally wet this evening. Additional snowfall should be limited to 
a couple more inches and mainly above 4500-5000 feet within the 
frontal band. 


Dry weather prevails both to the north and to the south of the 
roughly 20-30 mile wide frontal band...with some patches of fog 
forming. We do not expect fog to become too dense and widespread 
tonight due to variable cloudiness passing by at the middle and high 
levels. The frontal zone may drift a bit back toward the north 
overnight as upper level ridging noses northward from the California 
coast. However the band of precipitation should lose its dynamic 
support somewhat as the main upper jet axis shifts north and east of 
the front. Therefore precipitation along the frontal zone should 
dwindle overnight. 


Models show decent agreement that the next surge of warm air aloft 
should push another warm front across the district Monday/Monday night. 
This may produce a bit of isentropic lift and overrunning 
precipitation late Monday. Another vortmax is expected to ride along 
this front Tuesday...and most 00z models are showing an impressive 
amount of quantitative precipitation forecast for SW Washington as it taps into a modest atmospheric 
river. For example the 00z GFS showing as much as 1-3 inches for the 
S Washington Cascades. Snow levels are likely to have risen above 6000 feet by 
that point. 


By then the upper ridge will likely be dominant Salem southward... 
with some fog forming Tuesday night/Wednesday morning in the valleys. Despite 
an unseasonably warm air mass aloft...with 850 mb temperatures upwards of 
+10 degree c Wednesday...the valleys will likely be stuck in a bit of an 
inversion thus limiting temperatures somewhat. Maximum temperature forecast for Wednesday 
afternoon will be tricky as a result. It does appear Wednesday will be dry 
for most of the district as upper ridging takes charge. Weagle 


Long term...Wednesday night through Sunday...models continue to 
show a Pacific frontal system...associated with an upper level 
shortwave...moving across northwest Oregon and SW Washington on 
Thanksgiving day. There are still some discrepancies of when the 
rain will start. The European model (ecmwf) brings the front onshore during the early 
morning hours while the GFS holds off until daybreak. Expect chance 
probability of precipitation through Friday. The main upper level trough moves onshore over 
the weekend and will bring a much stronger and wetter system. Snow 
levels over the weekend could drop to the passes. As of now...it 
looks like we can expect to see hazardous travel conditions for 
those returning after the Thanksgiving Holiday. Temperatures in the 
extended continue to be near seasonal normals. Details of the 
impacts expected from next weekends system will continue to be 
refined with future updates. /64 


&& 


Aviation...a band of rain associated with a weakening frontal 
boundary is currently draped from just north of Newport through 
the central and south Willamette Valley. This boundary will push 
slowly south and weaken further later into tonight. Expect 
primarily VFR conditions in the area of the rain band...with 
areas of MVFR from time to time underneath any heavier rain. 


Behind the rain band...skies are beginning to clear with low MVFR 
to IFR stratus forming rather quickly after clearing. Expect this 
trend to continue across the area from north to south and west to 
east. Could see visible as low as LIFR...particularly along the coast 
and early Monday morning in the South Valley. Shallow fog will 
burn off by 17z-18z but any terminal which sees significant clearing 
tonight and thus thicker fog in the morning may have trouble 
clearing much at all Monday ahead of the next front. Said front 
will begin to spread light rain and possibly MVFR ceilings first to 
the coast Monday afternoon then inland Monday evening. 


Kpdx and approaches...some clearing tonight will allow patchy fog 
and/or low stratus to form...likely burning off by 17z-18z. 
Bowen/pyle 


&& 


Marine...a weakening front has moved slowly from north to south 
through the waters today...and is now located just north of 
Newport. Winds have dropped off even as the front has continued to 
weaken...and are now westerly at generally less than 10 knots. 
Expect the lull in the winds to last into early Monday. Then the 
next front is expected to move into the waters tomorrow. The 
latest forecast models are showing weaker winds than the previous 
model run and thus have cancelled the gale watch and instead 
issued a Small Craft Advisory for winds and extended the Small 
Craft Advisory for seas. Expect seas to remain 12-15 feet through 
tonight...decreasing to 10-12 feet during the day Monday. Bowen 


Winds may stay a bit gustier across the northern waters through middle 
week before a slow moving low pressure system begins to impact 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. Pyle

Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...Small Craft Advisory for winds from 10 am to 10 PM PST Monday 
for coastal waters from Cape Shoalwater Washington to Florence or out 
60 nm. 


Small Craft Advisory for hazardous seas until 4 am PST Tuesday 
for coastal waters from Cape Shoalwater Washington to Florence or out 
60 nm. 


Small Craft Advisory for rough Columbia River bar until 4 am
