NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
237 PM PDT Friday Jul 3 2015 


Synopsis...little change in the overall weather pattern is expected 
through the Holiday weekend and into early next week. A strong upper 
level ridge will remain over the region to keep inland temperatures well 
above normal with continued dry conditions. Early next week an upper 
level low cutting off near the central California coast may spin 
some moisture up toward the Lane County Cascades for a chance of 
thunderstorms. Some cooling looks possible late in the week as the 
upper level ridge gives way to a weak low pressure center aloft. 
&& 


Short term...a ridge of high pressure aloft Friday afternoon extended from 
the SW U.S. To off the coast of the Pacific northwest. The ridge...running 
across SW Oregon...will remain in place through Monday. Models continue 
to show the ridge weakening some over the next few days resulting 
the development of a col over western Oregon this weekend. Under the 
ridge northwest onshore pressure gradients have strengthened some...which 
coupled with decreasing heights aloft will take a little of the edge 
off daytime temperatures for Sat by cutting them down a few degrees. Models 
show not a whole lot of change to the air mass again sun...except 800 mb 
temperatures creep back up to around 22 degree c which should put high temperatures 
back close to Thursday highs. With the onshore flow marine clouds should 
fill back in along the coast with a limited push of marine clouds up 
the lower Columbia. A wind flow reversal along the coast indicated 
by both the NAM and GFS should help some clouds push into the Oregon 
Coast Range Sun night and early Monday...but overall air mass expected 
to change little so will still see inland temperatures topping out in the 
90s. Will leave a slight chance for some thunder in the Lane County 
Cascades Monday afternoon as GFS and NAM show some instability coming 
up from the S out of the low off the California coast. 


Long term...GFS and European model (ecmwf) show the upper col remaining over Oregon 
Tuesday and Wednesday for continued hot weather. This also leaves the S 
Cascades open instability and moisture aloft sneaking up from the 
S...so will keep a slight chance for diurnal thunderstorms over the 
Lane County Cascades both Tuesday and Wednesday. Models at this point are 
suggesting some relief to the extended heat wave coming around Thursday 
as the upper low cutoff off the California coast moves inland over California giving 
potentially bringing a SW push of marine air inland. Models indicate 
the troughiness over the western states is then reinforced Friday as 
another trough moves in off the North Pacific for even cooler air. Will 
trend temperatures downward a little more for Thursday and Friday given decent 
agreement in models with this type of solution...but still hold some 
reservations in buying completely into the change as models tend to 
struggle with cutoff lows especially this far into the extended period. 


&& 


Aviation...little change in the overall weather pattern with 
stable westerly flow aloft. Visible satellite shows that marine 
stratus along the coast has mostly burned off at this point...and 
expect VFR for the rest of the afternoon and early evening. 
However...expect the IFR stratus to reform along the coast later 
this evening...then push into the coastal gaps and up the Columbia 
River as far as Kelso overnight. Inland taf sites should remain 
VFR through Sat. Northwesterly winds will be breezy at times this 
afternoon and early evening. 


Kpdx and approaches...VFR will persist through Sat. Northwesterly 
winds will be breezy at times this afternoon and evening. Pyle 


&& 


Marine...high pressure over the NE Pacific and thermal low pressure inland 
will continue to produce breezy northerly winds over the coastal 
waters into Sat. The best winds are further offshore...where a 
Small Craft Advisory remains in effect through tonight. Winds are 
lighter near shore...with gusts around 20 knots. The thermal low 
pressure will move westward this weekend...weakening the pressure gradient 
over the waters. This should allow winds across all waters to drop 
below 20 knots late in the weekend and into next week. The forecast 
models are indicating that a southerly wind reversal will occur 
sometime sun. 


Expect periods of steep and choppy seas over the outer waters to 
continue overnight with combined seas of 7 to 8 feet and a dominant period 
around 8 seconds. Seas should gradually subside later this weekend 
as winds slacken...reaching around 4 to 5 feet by early next week.
