NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
921 PM PDT Friday Oct 31 2014 


Synopsis...a splitting upper level trough just off the coast will 
slowly move inland tonight and Sat with the bulk of the energy 
digging S towards California. Sat night and Sun morning a weak area of high 
pressure will move across the region...then a warm front coming in later 
sun and Monday is expected to bring a return to wet weather for the 
first half of next week. 
&& 


Short term...tonight through Monday...plenty of showers were 
observed across southwest Washington and northwest Oregon today 
behind a departing cold front which moved east of the Cascades this 
morning. The showers have mostly dissipated at this point as the 
surface temperatures are cooling and decreasing the low level 
instability. A look at the latest water vapor satellite imagery shows 
an elongated and splitting upper level trough just off the Pacific northwest 
coast this evening. Offshore shower activity is also apparent on 
satellite with the trough...so expect there to be some lingering 
showers overnight as the trough axis pushes onshore. The bulk of the 
precipitation associated with the trough will be down into California 
as the upper level energy is diving south. The best shower chances 
for US will be along the coast...where relatively warmer ocean 
temperatures will keep instabiltiy higher. There is also the 
potential for a few thundershowers along the coast. 


A much cooler air mass is now settling into the Pacific northwest behind the 
earlier frontal passage. As a result...expect our streak of 
significantly above normal overnight lows to end tonight. Low temperatures 
should drop well down into the 40s over the lowland valleys. Although 
this will probably feel chilly compared to our recent nights...the 
forecast lows are actually right about at seasonal averages. Some patchy 
fog is expected to develop over the valleys...although it may be 
mitigated somewhat by high clouds drifting into the region from the 
south. 


Instability associated with the upper trough moves further inland 
Sat through Sun morning...but a moist low level onshore flow 
develops in its wake. While probability of precipitation should be low through this time 
frame...am reluctant to drop probability of precipitation completely as model quantitative precipitation forecast fields 
suggest some threat for showers to persist through Sun morning. 
Finally on sun some warm air advection picks up in a weak westerly 
flow. A look at some isentropic fields in the GFS and ecwmf showed a 
deep layer of moisture with weak isentropic lift developing sun into 
sun evening along the 290k and 300k isentropes. This will initiate a 
period of rain that is likely to last past Monday as the westerly flow 
persists with isentropic lifting. GFS has tended to show the deep 
moisture and lift extending further S than the European model (ecmwf)...so will go 
with high probability of precipitation late sun through Monday...but indicate a little lower 
confidence across the southern zones. Pyle 


&& 


Long term...Monday night through Friday...the models are in good 
agreement and continue to show a strong frontal system moving across 
the region on late Monday...with rain likely continuing into early 
Wednesday. We could see a good amount of precipitation with this 
system...particularly in the northern portions of the County Warning Area and along 
the coast. We may need to keep an eye on the coastal and northern 
rivers as a result. The coast will likely see windy conditions with 
this front but valley winds should not be an issue. Upper level 
ridging looks to build in briefly allowing most of the region to dry 
out on Wednesday. The next frontal system looks to move through on 
Thursday. However...there remains some slight timing differences 
between the models with the European model (ecmwf) show a much more progressive 
solution. Due to the slight differences only minor changes were made 
to the extended forecast. /64 
&& 


Aviation...as convective clouds clear this evening...expect 
there will be areas of IFR visibilities and ceilings developing most likely 
affecting only the inland terminals. Guidance and 
experience show LIFR ceilings probable and a bit lesser chance for 
LIFR visibilities at keug and khio later overnight. Guidance also showing 
IFR ceilings in pdx area which seems likely early morning. Winds 
mostly calm across the board. Chance of more showers mainly 
Saturday afternoon with possible MVFR ceilings and visibility at affected 
terminals. 


Kpdx and approaches...clearing skies through the better part of 
tonight. IFR stratus developing around 13z through 18z then chance 
for brief MVFR ceiling with afternoon showers. Bowen/jbonk 


&& 


Marine...weak surface gradients and relatively light winds over 
the waters for the next 24 hours will result in mainly swell 
driven seas. Swell has increased to around 10 feet across the 
waters. Looks like swell even will be short-lived...dropping back 
below 10 feet a bit after midnight. Timing of current Small Craft Advisory looks 
good. 


Last Columbia bar observation this evening reported 8 to 10 feet 
seas so pushed rough bar up to 03z with suspected 10 feet seas 
occurring. Also extended rough bar to 11z based on expected Ebb 
influence. 


Next general marine impact looks to be Sunday through Tuesday 
morning with a combination of westerly swell and potential gale 
winds pushing seas into the teens to start the week. A stronger 
system is shown by both the GFS and European model (ecmwf) around the Wednesday 
night/Thursday time frame. Bowen/jbonk 


&& 


Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...Small Craft Advisory for hazardous seas until 2 am PDT Saturday 
for coastal waters from Cape Shoalwater Washington to Florence or out 60 
nm. 


Small Craft Advisory for rough Columbia River bar until 4 am PDT 
Saturday.
