NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
215 PM PST Thursday Mar 5 2015 


Synopsis...an upper level ridge of high pressure will remain through 
the weekend maintaining a dry and generally mild weather pattern. 
The upper ridge will weaken early next week and a front may bring 
rain to the region by Tuesday. 
&& 


Short term...tonight through Sunday. Visible satellite imagery 
depicts another generally clear day across much of the area with some 
thin cirrus continuing to stream overhead. We are well on track to 
another day with temperatures continuing to push well into the 50s 
across the region at this hour. Expect temperatures tonight to remain 
cool...though likely a few degrees warmer than last night for many 
locations. Thin cirrus likely will remain over the region overnight 
but nonetheless...some patchy fog may develop in parts of the 
interior tonight especially in the more fog prone locations. 
Meanwhile...forecast models remain in decent agreement that a wind 
reversal along the coast will occur...but enough offshore component 
will remain to prevent a strong push of moisture into the coastal 
areas and into the interior on Friday. Still think the bulk of the 
clouds will remain offshore...but it is possible that increased 
clouds will also make their way along the immediate coastline. 


Little change will occur into the weekend with high pressure 
continuing to drive our weather. A return to more offshore low-level 
winds and a drier northerly flow aloft will decrease clouds once 
again and drive any coastal cloudiness more offshore. High 
temperatures will remain well above normals for the weekend...while 
gradual warming in overnight lows will bring them closer to normals 
and well above freezing for most locations. 
&& 


Long term...Sunday night through Thursday...the upper ridge will 
gradually break down early next week after starting with the axis 
over the coast. As the upper ridge expands eastward Monday...models 
are showing a somewhat aggressive trough swing south from Alaska and 
east across British Columbia. This appears to open the door for a 
warm core cut off low centered near 150w to drift toward the pacnw. 
The northern shortwave may bring very light rain to the far northern 
reaches of the County Warning Area. The filling upper low gets close enough to the 
coast to spread rain well inland by Tuesday night. Models have 
consistently shown some loose version of this scenario for a few days 


Now so bumped probability of precipitation up to low end likely from Tuesday night Onward. 
The various medium range models do continue to struggle with the 
track of the upper low so confidence in actual precipitation amounts 
remains very low but find it difficult to expect any area getting 
more than an inch during the Tuesday through Thursday time frame. 
Temperatures will be modestly warm with snow levels fairly high so 
expect no significant addition to the Cascade snow pack. /Jbonk 
gradually break down early next week after starting with the axis 
over the coast. As the upper ridge expands eastward Monday. 
&& 


Aviation...VFR through Friday. There may be some patchy fog 08z- 
18z Friday...primarily along the S Washington and north Oregon coast near the 
bays...the Nehalem River Valley and possibly at and in the 
vicinity of keug. 


Kpdx and approaches...VFR through Friday morning with thin cirrus at 
times. Weishaar 
&& 


Marine...quiet weather pattern over the waters for the next 
several days. 1923z ascat pass showed general north-NE wind at 10 knots 
or less...except east near the shoreline. What is left of the weak 
thermally induced trough is likely located over the interior 
valleys. Latest NAM model still suggesting a wind reversal over 
the waters tonight. North wind returns for the weekend with 15 to 
20 knots gusts over the far southern waters Sat night and sun. Longer 
range models starting to show a little more agreement. Closed 
upper low over the central Pacific Monday drifts closer to the California 
and S Oregon coast Tuesday and Wednesday. GFS has gone away from its cool 
and wet northwesterly upper flow pattern to the more mild and somewhat 
drier southwesterly pattern of the European model (ecmwf) and Gem. 


Seas holding in the 3 to 5 foot range for for the next few days. 
Spectral analysis suggests there will be multiple 2 or 3 foot 
components through at least Friday...primarily from the west-northwest and south-southwest. 
Enp guidance shows 12 to 14 feet wave heights next Wednesday night and 
Thursday. Believe this to be overdone as the closed surface low is not 
all that strong in the models. The models also do not show any 
significant fetch region to develop waves that high. Brought seas 
up to 10 feet for now. Weishaar

Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...none.
