NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
916 am PDT sun Aug 2 2015 


Synopsis...as a strong positively tilted upper level ridge slowly 
moves east today...an upper level low off the California coast will 
continue steering more moisture and instability northward over 
western Oregon and into southwest Washington today into Monday... for 
a threat of some showers or thunderstorms. An upper level trough 
along the b.C. Coast will begin moving south toward the Pacific 
northwest later tonight and Monday...and have an increasing impact 
over southwest Washington and northwest Oregon during the middle week 
period for cooler temperatures and more night and morning clouds. 
&& 


Short term...as suspected Saturday...a considerable amount of 
convective cloudiness and debris have already spread over northwest 
Oregon and southwest Washington overnight and this morning...and even 
over the coastal waters. Lightning late Saturday was mainly near 
Willamette Pass...then shifted to over the coastal waters overnight 
and this morning. 


The area of moisture over the coastal waters and over the north 
coastal mountains into the South Washington Cascades with some 
showers. Have not seen any lightning with this area in a while. This 
area of moisture will move north into west central and northwest 
Washington during the middle day period and slowly out of our forecast 
area. The models this morning showed a weak upper jet segment with 
this moisture that moves north out of our area later today. 


Another area of moisture is moving north from southwest Oregon into 
Lane County this morning...and did produce some lightning an hour or 
two ago as it was crossing into Lane County from Douglas County. This 
moisture will continue moving north through northwest Oregon and 
eventually into southwest Washington through the afternoon and 
tonight. The models show another jet segment associated with a short 
wave pivoting through our forecast area from the south tonight into 
Monday morning. This takes some of the moisture back to the coast and 
into the coastal waters again. Expect a few showers to move across 
the area as this moisture continues to feed north. Cannot really rule 
out thunder anywhere as well. There will be some chance of thunder in 
the south part of our area this morning spreading north in the 
afternoon and evening. 


The short wave and moisture area will still be over the forecast area 
early Monday before moving east in the afternoon. 


By Monday an upper trough along the b.C. Coast will be sagging south 
along the coast toward the Pacific northwest. This will help turn the 
upper flow Monday afternoon to more southwesterly...and limit the 
thunderstorm potential later Monday to our southern Cascade areas and 
especially near the crest. The upper trough will continue to sag 
south with more energy in Washington by Tuesday...with more westerly 
flow aloft over southwest Washington and northwest Oregon. 
Again...the main threat of thunder for our area will be near 
Willamette Pass later Tuesday. 


The marine layer is again shallow and near the coast this morning. 
Will continue the heat advisory for the inland valleys today... 
though the clouds may affect how warm we get today. Humidities will 
be slowly rising today as well. The marine layer will begin pushing 
into the coastal gaps tonight and Monday morning...but inland 
coverage will be spotty. Inland temperatures will be lower Monday due to the 
gradual cooling of the air mass aloft. Expect better inland coverage 
of low clouds Tuesday morning...especially north. Temperatures Tuesday will 
be closer to normal especially north. Tolleson 


Long term...no changes. Previous discussion follows... 
the general trend in the extended period will be towards cooler 
weather. Models continue to show an upper level trough brushing by 
the region late Tuesday...but keeps most of the energy to our north. 
Will keep a slight chance of thunderstorms over the Lane County 
Cascades for late Tuesday due to some lingering instability. 
Temperatures return towards seasonal normals by Wednesday...but will 
increase slightly for the latter half of the week as a weak upper 
level ridge builds into the Pacific northwest. Models diverge 
significantly as we go into next weekend. As such...have used a broad 
brush approach for next weekend and introduced a slight chance of 
showers over the South Washington Cascades and a slight chance of 
thunderstorms for the Oregon Cascades. /64 
&& 


Aviation...previous discussion...VFR inland this morning but with 
some middle/high clouds from convection over SW Oregon will drift over 
the region. Slight chance of seeing rain/thunder over the southern 
half of the forecast area 10z-17z but chance appears small enough to 
preclude mention in any particular taf. At the coast...shallow IFR 
stratus will continue along the central coast and likely develops 
along the north coast by 11z. This stratus will retreat offshore 
around 18z for VFR conditions along the coast. Expect developing 
cumulus Sun afternoon/evening with the possibility of thunderstorms 
expanding over much of the area east of the Coast Range 03z-10z 
Tuesday...but again insufficient confidence to include in any particular 
taf at this time. 


Kpdx and approaches...VFR conditions tonight and Sunday. Some 
residual middle/high clouds from convection over SW Oregon will drift 
overhead this morning. Likely see cumulus development this afternoon 
with the potential for a thunderstorm. Chances best S and east of 
terminal and in Cascades...but cannot rule out one impacting the 
terminal during 04z-10z. Cullen 
&& 


Marine...previous discussion...a few thunderstorms offshore are 
drifting from S to north into the outer central Oregon coastal waters 
early this morning. Potential threats are lightning and gusty outflow 
winds...with the threat area expanding to cover much of the coastal 
waters this morning and again in the evening hours. 


Otherwise...little change to the overall pattern for Sunday with north 
winds over the waters. An overnight ascat pass revealed winds still 
around 20 knots over the outer waters...so will allow the advisory for 
winds to continue through 10 am as areas of marginally advisory 
strength winds may still exist. Another Small Craft Advisory for winds in effect for 
this afternoon/evening as more widespread gusts to 25 knots expected to 
redevelop. 


Meanwhile...the persistent northerly winds are maintaining steep seas 
over the waters of 6 to 7 feet at 6 to 8 seconds. Therefore...with 
conditions fluctuating above or very near our criteria for hazardous 
seas...the advisory for hazardous seas looks on track for today.
