NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland 
844 PM PDT Friday Apr 17 2015 


Synopsis...warm days and pleasant nights will continue for the next 
few days as high pressure dominates the Pacific northwest. Remnants 
of a weak cold front will slide south of the area tonight leaving 
some low clouds over the coast and locally inland through early 
Saturday. This will be followed by more high pressure and an even 
warmer air mass...potentially bringing the warmest days so far this 
year Sunday and Monday as inland temperatures exceed 80 degrees. The 
earliest chance of rain appears to be Tuesday as high pressure 
weakens and a cooler upper trough moves in for the middle of next 
week. 


&& 


Update...quiet night across the district with only weak remnants of 
the front leaving a bit of stratus affecting the central coast. Will 
probably see some radiation fog/stratus develop over the coastal 
valleys tonight and last through the early morning. Temperatures 
today overachieved the forecast by a few degrees nearly across the 
board. As such...have taken the currently forecasted day to day 
temperature trends and applied them to todays observed values. Have 
confidence in this method given flow turns slightly offshore through 
the weekend. The result is an expectation of temperatures around 80 
a day earlier on Sunday instead of on Monday. Monday may reach in to 
the lower 80s but still am not sure about the movement timing of the 
expected thermal trough over the area. If it slides over the 
Cascades by Monday afternoon then expect a minor marine push to keep 
mondays highs staying close to Sunday except along the coast. If it 
moves slower then models indicate...commonly seen...then Monday 
could be the warmest day with widespread inland temperatures in the lower 
80s. Decided on a blend between the two scenarios as a hedge for 
now. Will be shipping the updated package shortly. /Jbonk 


&& 


Aviation...widespread VFR conditions will continue through Sat. Low 
end MVFR ceilings along parts of the coast Friday evening will become less 
likely to continue overnight. Expect about a 20 percent chance of 
low MVFR ceilings to reform overnight...but as winds turn offshore early 
Sat morning any threat of MVFR ceilings comes to end after 14z. 


Kpdx and approaches...VFR conditions will persist over the next 24 
hours. A few clouds between 2k and 3k feet may form between 11z and 
16z...but the chances for a ceiling to form are less than 10 percent. 
&& 


Marine...gusty north winds are expected to continue through the weekend 
and into Monday as high pressure remains offshore with a trough of low pressure 
along the S Oregon coast. The winds will be strongest during the 
late afternoon and evening hours...slackening somewhat late at night 
and during the morning hours each day. 


A northwest swell around 14 seconds tonight is expected to subside a bit 
later tonight and Sat...bringing the total wave height below 10 feet. 
Seas are then expected to remain in the 6 to 9 feet range through Monday. 
&& 


Previous disc... /issued 243 PM PDT Friday Apr 17 2015/ 


Short term...tonight through Monday...satellite imagery barely shows 
an upper level trough moving across Washington this afternoon. Middle to 
high level clouds are racing out well ahead of the surface front... 
which lags behind and is falling apart just off the Pacific northwest coast. 
High pressure is already strengthening over the NE Pacific...with 
onshore flow increasing due to the high offshore and thermal low 
pressure over the Columbia Basin. 


Some stratus can be seen on visible satellite in the remnants of the 
surface front...along and just off the Washington/north or coast. Low clouds are 
expected to fill in along the coast tonight...potentially pushing up 
the Columbia into the pdx metropolitan Sat morning. Depending on how 
prolific the low clouds get...they could push through some of the 
coastal valleys as well. However 500 mb heights are forecast to start 
rising already by Sat morning...and the resulting subsidence may 
limit the depth and extent of low cloudiness. 


Flow will turn more northerly Saturday as high pressure strengthens 
across Washington and thermal low pressure begins to extend northward 
from California. The result should be a quick burnoff of low clouds 
Sat morning...with a mostly sunny and warm afternoon. 850 mb temperatures 
will already be on the increase by midday Saturday...reaching +10 to 
+12 degree c by afternoon per the 18z NAM. As a result temperatures Saturday 
should once again climb into the lower to middle 70s inland...with 60s 
along the coast. 


Strong high pressure aloft will persist Sunday and Monday...causing 
the air mass to continue to warm over the Pacific northwest. 850 mb temperatures tick 
up 1-2 degree c each day Sunday and Monday...supporting high temperatures a 
couple degrees warmer each afternoon. 18z NAM/12z European model (ecmwf) show 850 mb 
temperatures up to +14 degree c by Monday...which with full sunshine may be 
able to support our first 80 degree day of the year inland. Thermal 
low pressure pushes east across the Cascades Monday...potentially 
bringing enough onshore flow to cool off the coast...but any marine 
push will likely hold off until Monday night/Tuesday morning for inland 
areas.Weagle 


Long term...Monday night through Friday...clouds expected to 
increase Monday night as westerly flow will push marine stratus 
inland. Cloudy conditions with maybe a couple showers expected 
Tuesday ahead of the front forecast to move through Tuesday night or 
early Wednesday. The European model (ecmwf) brings the front in earlier than the GFS. 
A better chance for showers and possibly even thunderstorms will be 
Tuesday night into Wednesday as the front moves through. GFS model 
soundings indicate some instability...but confidence is not high 
enough for ME to put a chance of thunder in the forecast quite yet. 
Cooler...more seasonal temperatures expected to stick around through 
late next week...with unsettled northwesterly flow bringing 
shortwaves through the area with associated rain. -McCoy
