NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
848 am PDT sun Apr 20 2014 


Synopsis...high pressure will bring mainly dry and a little warmer 
weather today. The next Pacific cold front will approach the region 
Monday and move through Monday night bringing a cooler showery air mass. A 
warm front approaching the coast will keep a threat for showers 
going Wednesday...then another cool showery trough is expected late in the 
week. 
&& 


Morning update...quiet conditions on an spegg-tacular Sunday across 
the northwest. Cool temperatures with scattered clouds and patchy 
fog about. Expect filtered sunshine today with passing high clouds 
and readings into the middle 60s should be easily attainable with a dry 
warm frontal boundary lifting northward. Minimal cosmetic changes to 
grids this morning for sky cover/temperature trends. 


Largest impact today is the high surf still working its way through 
the waters with long period seas of 18-20 feet . Expect hazardous 
conditions in the surf zone to continue today...then begin to ease 
late in the day. Exercise caution if headed to the beaches today. Kmd 


&& 


Short term...early this morning it looked like the last of the 
showers associated with the departing trough were coming to an end 
over the north part of the forecast area. A transient surface high is 
expected to move across the Pacific northwest today for dry and warmer 
weather. The warm front lifting up to the Washington coast appears to 
lack moist isentropic lift this morning so will drop the chance for 
showers on the S Washington coast. 


Next Pacific system expected to approach Monday. Models continue to 
show the trough digging as it approaches the coast...so initially 
the front is expected to be slow to reach the coast with much of the 
best dynamics headed S. Flow however backs to the south-southwest aloft Monday 
bringing middle and upper level moisture up into the region. Will 
continue to carry an increasing threat for showers Monday and Monday 
night...but hold off on likely or higher probability of precipitation until Monday night when 
the front band finally pushes inland and the upper trough axis 
finally reaches the coast. As the cool upper trough moves inland 
showery conditions will persist into Tuesday. This will also usher in 
below normal temperatures Wednesday as 800 mb temperatures go below zero c. 


Long term...no changes. Previous discussion follows...Tuesday night 
through Saturday... the extended portion of the forecast is looking 
increasingly wet with below normal temperatures. We start out fairly 
quiet Tuesday night and early Wednesday...with a few showers around on the 
backside of an upper level trough that is departing to the east. The 
next frontal system is expected to bring steady rain beginning Wednesday or 
early Thursday. Confidence in the timing of this system is not high at 
this point. The 12z European model (ecmwf) run came in much more progressive than past 
runs...bringing rain onshore Wednesday afternoon. The 12z GFS and the 
majority of its ensembles hold the rain off until overnight Wednesday into 
Thursday. At any rate...precipitable water values with this system are 
looking fairly high so we will likely get a pretty good dose of rain 
through Thursday night. A broad and cold upper level trough will build 
into the NE Pacific for Friday into next weekend...bring more rain chances. 
Pyle 
&& 


Aviation...generally VFR conditions across the region today. A 
scattered-broken layer between 3000-4000 feet developed north of kpdx-ktmk 
line will probably persist through early afternoon. Otherwise 
just patchy fog across the area. Keug the only taf site with LIFR 
conditions that should improve to VFR 17z- 18z. 


Kpdx and approaches...VFR prevailing for the next 24 hours. 


&& 


Marine...large westerly swell train continues across the waters 
this morning. Model forecast is running about 1 to 2 feet above 
observations so have made slight adjustments to forecast for 
today and added a few more hours to the high surf advisory. 
Seas will slowly subside today...diminishing to around 15 feet 
tonight...and to 10 feet Tuesday morning. The small craft for hazardous 
seas continue through early Tuesday. 


A relatively quiet period in terms of wind over the waters 
through the first half of this week. A weak system will approach 
the waters this afternoon and could bring a few occasional gusts 
to 20-25 knots over the far northern outer waters. Otherwise...the 
next significant system arrives late Wednesday or Thursday...likely bringing 
small craft winds. Cullen 


&& 


Pqr watches/warnings/advisories... 
or...high surf advisory until 1 PM PDT this afternoon for central 
Oregon coast-north Oregon coast. 


Washington...high surf advisory until 1 PM PDT this afternoon for South 
Washington coast. 


Pz...Small Craft Advisory for hazardous seas until 5 am PDT 
Tuesday for coastal waters from Cape Shoalwater Washington 
to Florence or out 60 nm. 


Small Craft Advisory for rough Columbia River bar until 
3 am PDT Monday.
