NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland 
926 am PDT Thursday may 28 2015 


Synopsis...high pressure aloft will be over the forecast area 
through Saturday. A closed upper low over the northern rockies will 
continue to drift southeast today. Expect a little more warming 
today...and then inland daytime temperature should peak Friday. The 
upper ridge starts to flatten Saturday. The higher Cascades will 
continue to have a slim threat of late-day thunderstorms the next 
couple of days. The next upper low swings closer to the Oregon coast 
Sunday...resulting in a little more cooling but a better chance of 
Cascade thunderstorms. A much deeper marine layer is expected over 
the area early next week. 


&& 


Morning update... 
the visible satellite loop shows plenty of marine stratus at the 
coast this morning. A weak inland push brought a thin stratus layer 
into the coastal gaps and up the lower Columbia. Clouds filled in the 
I-5 corridor in SW wash and reached the Portland/Vancouver metropolitan 
area. The rest of the Willamette Valley stayed cloud free. Expect the 
inland stratus to burn off fairly quickly today...likely by around 
18z. Then another warm day is on tap for the region. 850 mb temperatures are 
forecast to reach 14 to 15 c which should support widespread highs into 
the low 80s for the interior lowlands. The coast will stay much 
cooler with clouds hanging on for much of the day and a northwest breeze off 
of the ocean. 


..previous short term discussion issued 149 am Thursday may 28... 
Short term...today through Saturday... 
water vapor loop shows an upper low over central Idaho...and a second 
low near 55n 131w. A 500 mb ridge axis extends between 125w and 130w. 
Water vapor also shows a dry slot sliding south over Vancouver Island 
and the Washington coast. On the smaller scale...stratus has already reached 
kkls at 08z. The 975 mb relative humidity forecast from the NAM valid 09z was a 
little behind...showing the 90 percent or greater values a little further 
west. Main forecast problem for today and Friday will be the 
potential for thunderstorms for the higher Cascades. The upper low 
that was centered near the Oregon...Washington...Idaho triple-point 
00z Thursday will continue to shift southeast today. This will allow 
northwest flow aloft over the forecast area. However...model 
soundings for a point near Santiam Pass...especially the 
NAM...maintain some degree of instability from late-afternoon through 
the evening today and Friday. Believe the models may be slightly 
over-doing the low-level dew points...thus generating 
higher cape values. Actually think the best chance for convection... 
albeit slim...will be over the higher S Washington Cascades. 


Expect a thinner marine layer today. The 06z NAM does not show marine 
stratus reaching kpdx...although the hi-res arc does indicate stratus 
getting to near Multnomah Falls by 15z. Hi-res model also suggesting 
the beaches will remain cloudy. May be a short period of scattered 
sky conditions late in the day from about konp northward. Model 850 
mb temperatures forecast to be around 15c today in the Willamette Valley... 
up about 1 degree from Wednesday. This should put the inland valleys in the 
lower 80s. Warmest day looks to be Friday with a slightly warmer start. 
The upper ridge starts to flatten a bit late Friday as an upper low over 
northern British Columbia slowly drifts south. 


Little change Sat with 500 mb high pressure remaining over the area. A 
slight amplification in the ridge Sat afternoon due to a developing 
low models show near 34n 138w Sat afternoon. This also induces 
slightly more unstable southwesterly flow aloft into the region. Will leave 
the slight threat of thunderstorms for the Lane County Cascades Sat 
afternoon. Weishaar 


Long term...Saturday night through Wednesday...weak shortwave 
ridging moves through the area early Sat night with an approaching 
upper level low pressure system nearing 130w by early sun. As this 
low pressure tracks inland...increasing clouds and much cooler 
temperatures move into the region. Showers will begin by late Sun 
afternoon or evening as the surface boundary slides onshore and 
across the region...with a chance for thunderstorms in the Cascades 
south of around Montana Hood. As this upper low continues to track along 
a generally southwest to east-northeast path across the region and 
then east of the Cascades...expect continued rain chances and cooler 
weather to continue through around midweek. While some modest 
differences in pattern evolution between model solutions suggest a 
bit of uncertainty in location and timing of rainfall amounts...the 
model guidance remains in remarkably decent agreement with respect 
to the showery pattern along with temperatures at or a few degrees 
below seasonal normals. 
&& 


Aviation...mostly VFR inland with IFR stratus along the Columbia 
River. Expect this stratus to thin and lift through 18z. Dry 
northerly flow aloft will keep conditions inland VFR...with a 
slight chance of thunderstorms over the Cascades between 20-04z. 
Marine layer along the coast will continue to bring a mixture of 
IFR/MVFR ceilings today and tonight. 


Kpdx and approaches...IFR stratus around 600 feet will continue to 
burn off through 17z. VFR conditions continue through Friday. /64 


&& 


Marine...not much change overall. High pressure remains locked over 
the NE Pacific...with weak pressure gradients. Seas continue as a mix of west 
and SW swell trains...but overall seas continue around 5 to 6 feet 
through the coming weekend. 


&& 


Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...none.
