NWS Forecaster Discussion




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


Synopsis...an upper level trough off the coast this morning will 
slowly move inland tonight and Sat while 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 late sun and Monday is expected to 
bring a return to wet weather for the first half of the new week. 
&& 


Short term...water vapor loop showed the upper trough along 130w 
has made very slow eastward progress today while also digging S off 
the California coast. Enahnced tops to the showers associated with the low 
appeared also to be shifting S with the main low center. Models all 
suggesting that showers will drop off drastically this evening over 
northwest Oregon and SW Washington. Will back off on probability of precipitation further overnight... 
although will maintain a slight chance for thunder along the coastal 
water until the trough axis moves inland Tuesday morning. 


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. 


&& 


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...will see weak to moderate low level instability and 
light showers through daylight hours ending 02z but feel main 
threat will be reduced ceilings under the occasional moderate shower. 
Showers look to be rather capped and not terribly deep thus have 
lost most concern for hail. As convective clouds clear this 
evening...expect there will be areas of IFR visibilities and ceilings 
developing most likely affecting only the inland terminals. Early 
guidance...and experience...shows LIFR ceilings probable and a bit 
lesser chance for LIFR visibilities at keug and khio later overnight. 
Will lean on including the higher confidence ceilings to dictate 
flight category and let the visibilities shake out if they develop. 


Kpdx and approaches...expect VFR ceilings under showers for the rest 
of daylight hours then clearing skies through the better part of 
the night. Will continue to follow guidance showing MVFR dropping 
to IFR ceilings developing at or after 11z tonight. /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 is on the increase and above 10 feet at buoy 89. 
This is a couple hours behind timing from 12z ww3 guidance 
package. These seas will propagate toward shore with buoys 29 and 
50 guidance also bringing seas above 10 feet. As such...have 
expanded the Small Craft Advisory for seas to cover the inner 
waters earlier today. Looks like mainly a 12 hour or less event 
with swell dropping back down overnight. Columbia bar conditions 
have been less than local model forecasted with the daytime Ebb 
barely showing any rise above the general seas. Will leave the 
overnight rough bar advisory in place...however...as incoming 
swell around 10 feet will keep bar seas above the 10 feet criteria. Do 
feel breakers are very unlikely though. 


Next 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. /Jbonk

Washington...none. 
Pz...Small Craft Advisory for hazardous seas until 2 am PDT Sat 
for coastal waters from Cape Shoalwater Washington to Florence or 
out 60 nm. 


Small Craft Advisory for rough Columbia River bar from 10 PM 
this evening to 3 am PDT Saturday.
