NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
932 am PDT Wednesday Apr 16 2014 


Synopsis...a warm front will be draped across SW Washington and most 
of northwest Oregon this morning...then slowly drift north this afternoon 
and tonight. The associated cold front is expected to move inland 
Thursday afternoon...followed by the upper level trough Thursday 
night. A gradual drying trend occurs Friday...but the next weather 
system impacts the region Saturday. The unsettled pattern looks to 
continue Sunday through early next week. 


&& 


Morning update...scaled back probability of precipitation some this morning into the 
afternoon...especially for the valley and the south with weak surface 
ridging in place. Expect another round of weak isentropic lift this 
afternoon to mainly affect the northern tier.That said it will be 
a mostly cloudy day with occasional dribs and drabs possible...and 
more sunbreaks south than north. Weak ridging keeps things at Bay 
this evening and then the upper trough/cold front make better 
progress toward the area for Thursday. 


Precipitable water values are about 2 Standard deviations above normal for April...so 
a bit of a wet day tomorrow but nothing too extreme...with a burst of 
more moderate to heavier rain with the front later afternoon/early 
evening with coupled forcing from the upper trough and cold front 
which will briefly steepen middle level lapse rates to near 7 deg/km. 
Snow levels do not get down to the passes until the tail end of the 
cold front Thursday night. /Kmd 


&& 


Short term...today through Friday...water vapor imagery shows a warm 
conveyer belt over the central and NE Pacific early this morning. 
Warm-advective over-running pattern will be the theme today. National Weather Service krtx 
dual-pol Doppler radar showing increasing radar returns over SW Washington 
and most of northwest Oregon as of 09z. Some isolated 45-50 dbz echoes 
moving across the north Oregon Coast Range. 


NAM...GFS and European model (ecmwf) in decent agreement regarding today and tonight. 
Expect categorical probability of precipitation across about the northern two-thirds of the 
forecast area this morning. Fairly decent isentropic lift on the 290k 
level 12z-18z as shown by the GFS. Blended total precipitable water 
at 0635z indicated a narrow swath of around 1 to 1.2 inches along 45n 
and 125-140w directed at northwest Oregon. Models indicate some 
amplification of the upper level ridge centered along the coast this 
afternoon...but 500 mb heights only get into the low to middle 560s. GFS 
hangs on to some light precipitation west of a kpdx-konp line and all of SW 
Washington this afternoon. European model (ecmwf) is fairly similar while the NAM is a bit 
more south with the quantitative precipitation forecast. All in all...a classic dirty ridge pattern. 
The 500 mb ridge axis shifts east of the Cascades tonight as a cold 
front pivots into a more north to S orientation. This cold front appears 
to be enhanced by a vigorous short-wave dropping into the mean trough 
position out around 135w. There are some model timing differences... 
with the European model (ecmwf) about 6 hours faster than the GFS. Believe the slower 
timing may be better as the upper flow becomes more parallel to the 
front. Categorical probability of precipitation in line for the northern two-thirds of the 
forecast are Thursday morning...then spreading to the remainder Thursday 
afternoon. Sharp upper trough moves across the area Thursday night...with 
snow levels dropping to near the Cascade passes by 12z Friday. Modest 
850 mb orographic flow Thursday night on the order of 15 to 25 knots per the 
GFS...but a little less on the European model (ecmwf). Kept a threat of showers going 
for the Cascades Friday morning. 


Zonal flow Friday afternoon with surface high pressure firmly established 
over the forecast area. GFS keeps the air mass somewhat cool Friday 
afternoon with 850 mb temperatures near 0c over SW Washington to about 6c over the 
central Oregon Cascades. This is about 2-3c cooler than the European model (ecmwf). 
Still expect Friday high temperatures to get near or just above seasonal norms 
with the high sun angle. Weishaar 


Long term...the dry period looks to hold Friday night and Sat morning. 
However...model differences evident with regard to the next system. 
GFS keeps things dry through 18z Sat. The European model (ecmwf) and Gem bring the 
leading edge of the next front to the coast by 18z. May need to 
boost probability of precipitation even more...but will let day shift make any needed 
adjustments after the 12z guidance arrives. Some question Marks about 
sun as the GFS...European model (ecmwf) and Gem all keep a threat of precipitation over SW Washington 
and extreme northwest Oregon. The rest of the forecast area should remain 
dry. As has been the case recently...models begin to diverge after 
day 5 leading to a lack of confidence in the models for days 6 and 7. 
The flow appears to remain progressive...so it seems prudent to 
follow something close to climatology for early next week. Weishaar 
&& 


Aviation...mostly VFR conditions today with a few areas of MVFR 
ceilings and light rain showers. Expect some mountain obscurations in 
Cascades with MVFR ceilings. Light rain will continue today...mainly 
from ksle northward. 


Kpdx and approaches...mostly VFR conditions today. Light rain 
persists next 24 hours. Cold front moves into area late Thursday morning 
bringing MVFR conditions. 


&& 


Marine...a warm front will continue to push across the region 
today. Pressure gradient not very impressive...so wind gusts will top 
around 20 knots. Seas are expected to run 7 to 8 feet through tonight. 
A stronger front arrives on Thursday. This front appears to bring 
better potential for winds gusting 25 knots...and will likely require 
a Small Craft Advisory as we get closer. Seas should come up a bit 
more with this system...likely 8 to 10 feet Thursday through Friday. Tw 


&& 


Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...Small Craft Advisory for rough Columbia River bar from 5 am to 9 
am PDT 
Thursday.
