NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland 
856 PM PDT Sat Mar 28 2015 


Synopsis...mild and mostly dry weather through Monday as flat upper 
level ridging remains over the Pacific northwest. Cold front will push across 
region late Monday...ushering in a much cooler and more seasonable 
air mass...along with showers and lower snow levels. 
&& 


Short term...tonight through Tuesday... 
a few lingering showers over the Cascades this evening...otherwise 
will maintain light onshore flow with variable middle and high clouds 
over the region tonight and Sun. Afternoon high temperatures should climb 
back into the middle to upper 60s over the interior lowlands. 


An upper level trough will dive down from the Gulf of Alaska on 
Monday...finally driving the stalled frontal boundary onshore as a cold 
front. Expect rain to push onto the coast Monday evening...then inland 
overnight. The upper level trough will move through on Tuesday...ushering 
in a significantly cooler air mass. The forecast models are indicating 
that there will be plenty of postfrontal showers across the region on 
Tuesday. The forecast model soundings are also looking decently unstable...so 
may need to look at adding thunder chances to the forecast in the next 
day or two. At the very least...it will probably be one of those days 
with periodic heavy showers...some likely containing small hail. The 
colder air should also drop snow levels down to Cascade passes where 
several inches of accumulating snow may fall. /Rockpyle 


Long term...Tuesday night through Friday...a progressive pattern is 
expected for the extended forecast period. Behind the upper level trough 
on Tuesday...forecast confidence is fairly high that another shortwave will 
move onshore Wednesday...bringing continued showers and mountain snow into 
Thursday morning. There is then a shortwave upper level ridge that is 
modeled to move into the region on Thursday. This may end up providing a 
brief break from the shower activity later Thursday into Friday before a 
deep upper trough moves toward the coast on Friday into next weekend. 
Forecast confidence becomes lower toward the end of the week. Friday could 
end up being mostly dry...but the forecast models seem to be trending 
toward speeding up the arrival of the deep trough...which would 
bring more rain onshore Friday. Pyle 


&& 


Aviation...VFR conditions expected through 06z Monday. A drier air 
mass...less onshore flow along with overriding middle and high clouds 
should keep radiational clouds or fog from developing. 


Kpdx and approaches...VFR conditions expected through 06z Monday. 
/26 


&& 


Marine...surface pressure gradient continues to increase a bit in 
between building high pressure over the waters and a low pressure 
system in the Gulf of Alaska. Not much to compare with models 
which are indicating low end Small Craft Advisory winds over the 
northern outer waters. There was an ascat pass around noon today 
that was comparable to model forecast. Winds should ease 
overnight. 


Seas will hold around 8 feet tonight...before increasing 8 to 10 feet 
Sun morning into Monday. Buoy 46005 trends this evening compares 
favorably with enp guidance so will adjust seas up a foot or two 
on sun. Have enough confidence at this time to issue a Small Craft 
Advisory for the outer waters for sun. Ten foot seas may 
occasionally reach the nearshore waters on sun but confidence not 
high enough at this time. 


Further on...winds become southerly and increase Sunday night and 
Monday ahead of an approaching frontal system that will cross the 
waters Monday night. A Small Craft Advisory for winds likely 
needed for this time...as well as an advisory for hazardous seas 
on Monday night into Tuesday with seas building into the 10 to 12 
feet range. Cullen /26 


&& 


Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...Small Craft Advisory for winds until 5 am PDT Sunday for waters 
from Cape Shoalwater Washington to Cascade Head or from 10 to 60 nm. 


Small Craft Advisory for hazardous seas from 5 am to 5 PM PDT 
Sunday for waters from Cape Shoalwater Washington to Cascade Head 
or from 10 to 60 nm-waters from Cascade Head to Florence or 
from 10 to 60 nm. 


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


Small Craft Advisory for rough Columbia River bar from
