NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service Portland or 
915 PM PDT Monday Jul 21 2014 


Synopsis...a low pressure system will bring an increasing threat 
of showers to the area Tuesday and especially Wednesday. A few 
thunderstorms will be possible near the Cascade crest Tuesday 
evening. Even though Wednesday will likely be the coolest day of the 
week...thunder will be possible with any of the heavier showers. 
Drier and more summerlike temperatures are expected to arrive late in 
the work week and continue into the weekend. 


&& 
Update...did not make any changes with the evening update as the 
forecast is on track. Water vapor imagery shows a semi splitting 
upper trough over the NE Pacific with an upper low offshore the 
British Columbia coast and another one off of Southern California. 
There is also an upper shortwave between these two lows digging off 
of northen California. These sysems are steering a band of middle level 
moisture across Oregon. A weak front that was stalled south of Lane 
County this afternoon has shifted north this evening and is 
generating some light showers over Lane County. A band of convecdtion 
south of this front is approaching Lane County...but should remain 
south and east of Lane County. 


Previous discussion follows...tonight through Thursday...a loop of 
water vapor satellite shows a shortwave digging southward near 135w 
and 40n. Visible satellite imagery shows plenty of middle level clouds 
streaming northeastward into southwest Oregon along an old middle level 
baroclinic zone. While Doppler radar has looked rather ominous 
underneath this band...most of the precipitation has been falling in 
the form of virga. However...the lower atmosphere is beginning to 
moisten from the top down near Roseburg where a couple of RAWS 
stations have recently measured a hundredth. While models produce 
little quantitative precipitation forecast across our County Warning Area tonight...most models agree this band will 
hold together...if not strengthen slightly...as it becomes 
increasingly warm frontal and shifts ever so slowly northward 
tonight. As a result...slight chance probability of precipitation were introduced for tonight 
to the south and east of Portland due to this band of precipitation. 


As a more powerful shortwave trough currently digging southward near 
the Queen Charlotte islands...continues southward Tuesday...the middle 
level flow will buckle and turn more southerly across the area later 
Tuesday. With increasing middle to upper level support...the 
aforementioned band of middle level moisture will strengthen further and 
bring an increasing threat of precipitation to our northwestern zones 
Tuesday afternoon. Meanwhile...the Cascades will begin to 
destabilize as skies clear a bit. A cap may inhibit surface based 
convection from developing late Tuesday afternoon...but 
thunderstorms developing further south of the County Warning Area...may clip our 
Cascades as they move northeastward Tuesday evening...particularly 
across eastern Lane and Linn counties. 


The main vorticity maximum and cold pool associated with the aforementioned 
shortwave trough should pivot eastward...if not slightly 
northeastward...across the northern half of the forecast area 
Wednesday. Cloud cover may initially limit convection...but with 
daytime heating...sun breaks should allow showers and isolated 
thunderstorms to bubble up during the afternoon...particularly across 
the northern half of the County Warning Area. Many of the foothills and some valley 
locations should see wetting rains. Showers activity should decrease 
Wednesday night. A few showers may linger across our northern zones 
on Thursday...but in general most locations should see much drier and 
pleasant weather on Thursday. /Neuman 
&& 


Long term...an upper-level ridge is forecast to build back in over 
the Pacific northwest bringing high pressure over our area. 
Southwesterly winds and generally sunny skies will cause 
temperatures to increase by early this weekend. Temperatures are 
forecast to get back into the middle 80s by Friday and possibly reach 
the low 90s in some areas inland as early as Saturday. -McCoy 
&& 


Aviation...VFR conditions prevail this evening...with ceilings 
around 10k-25k feet. Band of rain is lifting north across the south 
Willamette Valley this evening...bringing light rain to the area 
and will gradually spread north towards ksle tonight. Expect some 
lowering clouds along the coastal areas late tonight/early 
Tuesday...with the potential for brief periods of local MVFR though 
confidence remains somewhat low that ceilings lower into MVFR. 


Kpdx and approaches...VFR conditions next 24 hours with 
increasing high clouds. Cullen/27 
&& 


Marine...relatively quiet conditions over the waters continue 
tonight as the surface gradient remains weak...keeping winds 
generally 10 knots or less. Seas remain near 5 feet through tonight 
before decreasing into the 3 to 5 feet range through Thursday. 


A weak low pressure systems will pass through the waters Tuesday into 
Wednesday...but with little impact as winds should remain 15-20 knots or 
less. Later this week...high pressure redevelops over the NE Pacific as 
thermal low pressure builds over north California...bringing a return to 
gusty north winds and steep wind driven seas Friday through the weekend.
