NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
914 am PDT Tuesday Jul 22 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 over the Cascades mainly late this 
afternoon and for this evening. Wednesday will likely be the coolest 
day of the week...however...thunder will be possible with any of the 
heavier showers as the upper low crosses overhead. Drier and more 
Summer-like temperatures are expected to arrive late in the work week 
and continue into the weekend. 


&& 


Update...where to start...water vapor satellite imagery shows an 
elongated longwave trough over the eastern Pacific with a number of 
features playing into our current and anticipated weather over the 
next 48 hours. First...a shortwave trough digging southward near 135w 
and 35n has allow a middle level baroclinic zone to shift northward 
overnight across the area. Frontogenesis along this boundary 
overnight helped produce between a quarter and a half inch of rain 
for the northeastern part of the Willamette Valley...and the South 
Washington Cascades. This area of precipitation will shift northeast 
of our forecast area in the next couple of hours. 


Visible satellite imagery this morning reveals plenty of middle level 
clouds once again streaming northeastward into southwest Oregon. 
Precipitation generally remains spotty and light in nature underneath 
this band with Grants Pass...Roseburg and Eugene all tracing in the 
last couple of hours. Anyway...this band of moisture is centered 
along another middle level baroclinic zone that is forecast to shift 
northward as today progresses. Hit or miss...more nuisance type 
showers are anticipated to spread northward across the forecast area 
today...but no large areas of organized precipitation are expected to 
develop underneath this band. 


As this area of clouds shifts northward...our southern Cascade zones 
will see increasing sunshine and begin to destabilize. With 40-45 kts 
of bulk shear and relatively fat cape...more organized 
supercellular type storms capable of producing large hail and 
damaging winds will be possible. However...and this is a big 
however...we are still concerned that this surface based convection 
will remain capped to the west of the crest this afternoon and 
thunderstorms will not get going until shifting east of the 
Cascades. Further a distinct vorticity maximum...apparent in water vapor 
imagery...currently lifting into the Bay area is forecast to begin 
lifting more northeastward than northward today. This would end up 
placing the best middle level support for thunderstorms just east of 
our forecast area late this afternoon and evening. Plus...the south-southwest 
to SW flow at 700mb will push any developing convection east of the 
crest quickly. Nonetheless...there is a decent chance towards the 
evening hours that convection developing in eastern Douglas and 
Klamath counties will become more elevated and clip eastern Lane and 
Linn counties when the middle level flow is most southerly. As a 
result...continued the scattered wording of thunder in this region 
with at least a mention of gusty winds and small hail in the grids. 


Finally...a larger and more organized shortwave trough currently due 
west of Oregon near 135 west will begin to elongate and shift 
northeastward across our northern zones Wednesday. Low to middle level 
frontogenesis ahead of this system should produce a north to south 
oriented band of steady rain that will shift eastward across the 
area Wednesday morning into early afternoon. A quarter to half inch 
of rain over a good portion of the forecast area is not out of the 
question...especially north of Salem. Clearing behind this feature 
should allow the atmosphere to destabilize in the middle to late 
afternoon and produce scattered showers with isolated very short 
lived thunderstorms...more reminiscent of Spring. 


Otherwise...the drying trend Wednesday night into Thursday looks on 
track. /Neuman 




Long term...no changes...previous discussion follows. 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...a band of rain continues to slide north across the 
region bringing a mix of MVFR and VFR conditions to the Portland 
metropolitan area terminals.Another line of rain is moving into the S 
Willamette Valley and Cascades and will slide north today. Temporary 
reductions to MVFR...or possibly high end IFR...possible at times 
in heavier rain. Otherwise...expect overcast skies with ceilings around 
4000 feet. Higher terrain and mountains obscured today. Another 
round of rain and lowering ceilings expected tonight after 06z at the 
coast...and around 10z-12z across the interior...with MVFR 
conditions likely at this time. 


Kpdx and approaches...line of rain should clear the terminal by 
17z with ceilings gradually lifting to around 4000-5000 feet by 18z. 
Expect VFR conditions to generally continue through 12z...though 
heavier rain at times may bring temporary reductions to MVFR. 
Cannot rule out some thunder development over eastern approaches this 
afternoon/evening but not expected at terminal at this time. Cullen 


&& 


Marine...relatively quiet conditions over the waters continue 
today as the surface gradient remains weak in between 
systems...keeping winds 15 knots or less. Seas remain 3-4 feet today 
with a continued small west-northwest swell. 


A low pressure system will pass through the waters late Tuesday into Wednesday. 
Models have trended to indicate the potential for marginal small 
craft winds on Wednesday with this...but confidence is low at this time 
due to uncertainty in the track and strength of the low. Later 
this week...high pressure redevelops over NE Pacific as thermal low pressure 
builds over north California. This will bring a return to gusty north 
winds and steep wind driven seas...particularly in the late 
afternoon and evening hours...Friday through the weekend. Cullen
