NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
245 am PDT Thursday Jul 2 2015 


Synopsis...strong high pressure aloft will persist over the forecast 
area for the next several days. The warmest day of this recent hot 
period appears to be Sunday. Slight cooling looks to occur early next 
week...but daytime temperatures will remain several degrees above 
normal. 


&& 
Short term...like the song says...the heat GOES on. Strong high 
pressure aloft will maintain its hold over the forecast area through 
the short term. Water vapor imagery shows a short-wave moving across 
southern Vancouver Island as of 09z...putting a slight Dent in the upper 
ridge. Normally...the passage of such a short-wave would enhance the 
onshore low-level flow. This does not look to be the case this time. 
The Jul 2 00z ksle sounding yielded an 850 mb temperature of 23... 
little higher than the 24-hour forecast. Latest GFS indicates 22c for 
00z Friday. Overall...little change in maximum temperatures compared to Wednesday. Thin 
ribbon of marine stratus along the S Oregon coast slowly working its 
way north...up to near Cascade Head at 09z. Hi-res arw model seems to 
be handling this reasonably well. Model shows stratus reaching kast 
and the S Washington coast around 12z...but little inland penetration. 


Models suggest a little more onshore flow Thursday night and Friday for 
slight cooling. GFS shows 850 mb temperatures around 21c for ksle and 
kpdx...down about a degree from Thursday. SW Washington may get the best 
relief...albeit minor...Friday with lower 500 mb heights. Sat appears to 
be similar to Friday. May need to extend the heat advisory through 
Saturday...but will let the day shift make the call. All in all... 
looking at a good possibility of another 3 90 degree or higher days 
for many areas. That would be 13 90 degree days for kpdx...well above 
the seasonal norm. Weishaar 


Long term...the strong ridge extending northwest to southeast across the region 
at the end of the weekend is expected to gradually erode as the high 
consolidates over the NE Pacific off the British Columbia coast. However...the mex 
guidance shows sun being the warmest day of the long-duration hot 
spell. The GFS and European model (ecmwf) show much of the forecast area in a 500 mb 
col area sun and within a broad thermally-induced surface trough. 
European model (ecmwf) shows some moisture trying to work northward from northern cal but do not 
think it will reach the southern part of the central Cascades. However... 
this will be something that will need to be monitored. After another 
hot day or two sun and Monday...the developing troughiness aloft will 
lower heights and encourage a stronger onshore flow. This is likely 
to result in cooler temperatures Tuesday and Wednesday and more marine clouds pushing 
inland. The region will also become more susceptible a southerly 
flow aloft at times spreading moisture and instability aloft up from 
the S. Weishaar 
&& 


Aviation...VFR will persist inland next 24 hours with dry/stable 
westerly flow surface and aloft. Coast is a different story with 
widespread IFR/LIFR Lincoln City southward...likely to linger 
through at least midday. Patchy IFR is also developing further 
north with kast reporting bkn008 in the past hour. Suspect this 
will become a little more widespread by 12z but not quite as solid 
as the stratus along the central coast. 


Kpdx and approaches...VFR with dry onshore flow next 24 hours. Light 
west-northwest winds pick up to 10-15 knots between 21z-04z. Weagle 


&& 


Marine...classic summertime pattern with strong high pressure 
over the NE Pacific and thermal low pressure inland...resulting in 
gusty afternoon and evening north-northwest winds along the coast. Decided to 
show more of a diurnal trend in the winds along the coast...with 
winds slackening some during the night and morning hours while 
they remain more steady offshore. Expect steep short-period seas 
from the gusty afternoon/evening winds...and more persistent steep 
seas in the outer waters. Square seas of 8 feet/8 second already being 
reported at buoy 46089...so we issued an Small Craft Advisory for seas outer waters 
through Friday. Strong northwest winds off Vancouver Island the next couple 
days will also generate some short period swell which will affect 
the S Washington/north or waters as well. The combination of the locally 
generated wind wave and the fresh swell could push seas up towards 
10-11 feet by Sat morning...so the Small Craft Advisory for seas may need to be 
extended/expanded eventually. 


Thermal low pressure is expected to drift offshore later this 
weekend...shoving the strongest pressure gradient offshore and 
allowing winds to ease for the coastal waters. Seas should come 
down as well...subsiding to background swell and light wind wave 
early-middle next week. Weagle 


&& 


Pqr watches/warnings/advisories... 
or...heat advisory until 9 PM PDT Friday for northwest Oregon interior 
lowlands...Cascade foothills...and central Oregon Coast Range. 


Washington...heat advisory until 9 PM PDT Friday for lower Columbia and 
SW Washington interior lowlands. 


Pz...Small Craft Advisory for winds from 11 am this morning to 3 am 
PDT Friday for waters from Cape Shoalwater to Florence from 
10 to 60 nm offshore. 


Small Craft Advisory for hazardous seas until 6 PM PDT Friday 
for waters from Cape Shoalwater to Florence from 10 to 60 nm 
offshore. 


Small Craft Advisory for winds from 11 am this morning to 11 PM 
PDT this evening for coastal waters from Cape Shoalwater to
