NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
205 am PST Wednesday Mar 4 2015 


Synopsis...high pressure will dominate this week and maintain a dry 
weather pattern. Daytime temperatures will gradually warm each day 
this week with Valley High temperatures climbing into the 60s 
this weekend. The upper ridge will weaken early next week and a front 
may bring rain to the region next Tuesday or Wednesday. 
&& 


Short term...today through Friday night...clear skies and relatively 
calm winds overnight has resulted in most inland temperatures to drop 
below freezing early this morning. Some coastal locations have also 
dropped to near or at freezing like Astoria and Tillamook. 


Water vapor imagery shows an upper ridge of high pressure over the 
Pacific northwest with the ridge axis just offshore. This has resulted in 
dry air across the region with dew point temperatures in the middle to 
upper 20s. Surface observations at some locations are showing the 
temperature/dewpoint spread becoming smaller and there may be local 
spots with shallow fog by sunrise, but most locations will remain 
clear. Temperatures this afternoon will be slightly warmer than they 
were on Tuesday. 


There will be little change in the weather tonight and Thursday as 
high pressure holds over the area. An upper level trough will move 
over western Canada Thursday evening and flatten the upper ridge. 
There may be an increase of high clouds with the trough...but these 
will have little impact to the weather. 


A weak surface low offshore of southern Oregon will result in a wind 
reversal for the coast Friday. Southerly winds are expected near 
Florence and New Port early Friday morning...reaching Tillamook 
around noon. The southerly winds will increase surface moisture and 
likely bring stratus/fog to the immediate coast. The temperatures for 
the coast will not likely be warmer Friday...in fact they may be a 
few degrees cooler. 


Weak onshore winds Friday night may bring the moister and cooler 
coastal air further inland. However...a subsidence inversion from the 
upper ridge should limit how far inland the stratus will go, but 
expect the increase of inland low level moisture to result in more 
widespread fog inland. Any fog should be shallow and burn off quickly 
Saturday. Tj 


Long term...Saturday through Tuesday...the upper ridge will 
gradually shift from being centered near 130w late this week to then 
expand eastward across the western Continental U.S. Through early next week. 
Main change was to bump temperatures up another couple degrees for 
the weekend bringing most valley locations into the middle 60s and the 
coastal areas to the upper 50s to lower 60s. Not much surface 
pressure gradient to speak of or else we could have easily hit the 
magical 70 degree mark if we had offshore flow. As the upper ridge 
expands eastward Monday...models are showing a somewhat aggressive 
trough swing south from Alaska and drag a cutoff low out toward 150w 
toward the pacnw coast. Have delayed any mention of rain until 
Tuesday as medium range models are in modest agreement in bringing 
the filling upper low close enough to the coast to spread rain well 
inland Tuesday night. Am somewhat skeptical this will fully come to 
fruition as the models indicate as we have seen this time and again 
this winter at that time range. This one is a little different, 
however, as the eastern half of the Continental U.S. Appears to be losing its 
semi-persistent trough which could open the door as advertised. 
Another factor is the timing of the Alaska trough. If it's much 
faster or slower at swinging across the north then the timing will 
be off and it may not gather the cutoff low and leave it well 
offshore. /Jbonk 
&& 


Aviation...great day for flying. Dry northerly stable flow 
aloft will maintain mostly clear skies with light winds. Similar 
to Monday am...will again have patchy fog again this am until 17z 
just about anywhere. 


Kpdx and approaches...VFR continues under dry stable air mass. 
Will have patchy fog to west and north of the field...but not likely to 
affect Ops area. Rockey. 
&& 


Marine...little change. High pressure firmly in control this week. 
Surface pressure gradient remains fairly weak which will keep 
light northerly winds at or below 15 knots for the next several days. 
May have gusts near 20 knots over the central Oregon waters as a 
weak thermal trough builds up the south Oregon coast. Seas remain 
3 to 5 feet. 
&& 


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