NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
225 am PDT Sat Apr 19 2014 


Synopsis...a cold front off the coast early this morning will move 
inland today...crossing the Cascades by late today. Showers will 
decrease tonight as the parent upper trough moves east as well. Weak 
higher pressure will move in Sunday for generally dry weather on 
Easter...except some moisture may brush the far north coast zones. 
The next front will become north south oriented Sunday night and 
stall off the coast as energy digs toward California for more mostly 
dry weather...but then move onshore Monday and Tuesday for more rain 
or showers. The remainder of next week looks unsettled as more 
precipitation moves in at times. 
&& 


Short term...cold front was seen on satellite about 200 Michigan offshore 
early Sat morning...making steady progress eastward and on track to 
reach the coast late this morning. Clouds mainly middle and low level 
with the front...matching the model cross sections suggesting 
moisture generally below 700mb. While moisture is on the shallow 
side...the front itself appears moderately strong and is synched 
with a shortwave aloft providing well timed lift. Will keep probability of precipitation 
high today for the frontal passage although the duration may be on 
the short side. Satellite shows showers are active behind the 
front...and initially late today into this evening low level flow is 
onshore favoring showers especially for the orographically favored Cascades 
and Coast Range. 


As a surface high builds in late tonight and sun...and an initially 
flat upper ridge moves across will see dry weather return along with 
warmer temperatures again for sun. The pattern amplifies Sun night and Monday 
as the next trough in a progressive pattern digs offshore and the 
downstream ridge over the interior western states builds. As the 
flow over the Pacific northwest backs to the south-southwest middle and upper level 
moisture expected to increase. Model soundings suggest air mass at 
best marginally unstable...and with dynamics digging the trough S 
prefer to limit probability of precipitation out ahead of the front Monday to chance category 
inland...but higher along the coast as a front and shortwave 
approach late in the day. SW onshore flow coupled with falling 
heights aloft point towards cooler marine air pushing back in Monday. 


Long term...no changes. Previous discussion follows... 
Monday night through Thursday...flow continues to amplify Sunday 
night and this will Orient the cold front offshore more north to 
south...thus any precipitation will remain well offshore Sunday 
night. The cold front finally gets a shove as the upper jet noses 
into the area. Precipitation is mainly tied to the front...but with 
the marginally unstable SW flow...models show that there could be 
some showers in the afternoon mainly for the Cascades...as middle level 
lapse rates hover in the 6 to 7 degree/km range. Instability parameters 
are not that impressive...so thunder potential looks low at this 
time. 


Looks like Tuesday and Wednesday will be characterized by cool and damp 
conditions as the deep upper low migrates across the Pacific northwest and into 
the northern rockies. After the first large upper trough clears late 
Tuesday night and maybe a break in showers Wednesday...another deep 
upper low will spread several waves of shower activity through the 
area for the latter half of the week.. /kmd 
&& 


Aviation...VFR prevailing under clear skies across the region as 
of 09z. Expect increasing clouds early this morning ahead of cold 
front approaches. Expect MVFR ceilings around 2000 feet with rain to 
reach the coast by 14z...and pushing across the interior around 
18z. Conditions should trend towards VFR late afternoon and 
evening. 


Kpdx and approaches...VFR through early this morning. MVFR ceilings 
around 2000 feet likely around 18z with rain as cold front 
approaches. Then becoming VFR around 00z sun. Cullen 


&& 


Marine...a strong low pressure system moving into the Alaska 
Panhandle will push a cold front across the waters today which 
will bring Small Craft Advisory winds over all waters starting 
early this morning through the day. Some occasional gusts in the 
30-35 knots range possible near the front...which should push ashore 
around daybreak Sat. Winds will diminish late this afternoon 
across the central Oregon waters and today across the north. 


A large swell train will follow the front tonight into sun. Seas 
will rapidly increase to 17 to 20 feet at 16 seconds when the swell 
arrives around 11 PM tonight...and peaking through 5 am sun. Seas 
will then gradually subside through Sun afternoon...diminishing to 
around 15 feet Sun night...and to 10 feet early Tuesday. 


A high surf advisory continues for Sat night through Sun morning 
for the South Washington and north Oregon coasts. It appears the 
central coast will remain just shy of criteria...but all 
individuals along the beaches should exercise caution this weekend.
