NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Pendleton or 
1020 PM PDT Monday Apr 20 2015 


Short term...strong upper ridge remains over the region tonight 
into Tuesday morning with mainly clear skies. An upper trough will 
be approaching the coast during the day. Southwest flow will be 
developing during the afternoon with some weak instability. Expect 
to have some cumulus over the mountains by middle afternoon. Models 
still imply scattered showers and isolated thunderstorms may develop 
over central and northeast Oregon in the evening and continue 
overnight. Temperatures will be on the warm side Tuesday with highs in the 
70s to lower 80s. Westerly winds will increase during the day in 
response to the approaching trough. Much cooler Wednesday as the 
trough moves through the forecast area. 94 


Aviation...06z tafs. Mainly clear skies tonight. Increasing cirrus 
Tuesday. Scattered cumulus over the mountains in the afternoon and 
evening. Slight chance of showers or thunderstorms rdm bdn after 
00z. Light winds tonight then westerly winds increasing Tuesday to 
10-25kt.

Previous disc... /issued 438 PM PDT Monday Apr 20 2015/ 


Short term...tonight through Thursday...an upper level high 
pressure ridge will continue over the Pacific northwest through 
tonight. This ridge will shift east Tuesday due to the approach of 
an upper trough. Conditions tonight through Tuesday morning will be 
fair and dry with mainly light winds. Overnight lows will be a bit 
warmer than this morning due to a warmer day today. Increasing 
southerly flow aloft ahead of the approaching Pacific trough will 
push moisture and instability north from California Tuesday 
afternoon and evening. As such isolated to scattered showers will 
develop over south central Oregon Tuesday afternoon and then work 
their way north into central and east central Oregon later Tuesday 
afternoon and Tuesday evening. There will be enough instability for 
a few thunderstorms over central and east central Oregon late 
afternoon into the evening as well. A few showers may be possible 
over the Washington Cascade east slopes though increasing west winds 
should be a limiting factor. The area of showers in central and east 
central Oregon will move north-northeast overnight into Wednesday. 
Thus these showers are expected to affect the Blue Mountains and 
their adjacent foothills, the Grande Ronde Valley and Wallowa County 
at various times Wednesday. Winds will increase across the Columbia 
Basin, the Columbia Gorge and the Kittitas Valley Tuesday night. 
These winds will persist into Wednesday. Winds in the Kittitas 
Valley are expected to reach 30 to 35 miles per hour sustained with higher 
gusts, and will issue a Wind Advisory for this area. Most of the 
showers will end Wednesday night. May see a few showers near the 
Cascade crest Thursday, and possibly a few over eastern Wallowa 
County. Otherwise Thursday should be dry with seasonal temperatures. 90 


Long term...Thursday night through Monday night...the long term 
period will be quite active with several systems moving through the 
area. The first and weaker trough will be over the forecast area 
Thursday night into Friday. This system looks fairly moisture 
starved and therefore just added a slight chance to chance for 
showers into the forecast during this time. Westerly winds could 
turn a bit breezy late Thursday night into Friday night over parts 
of the area. This weather system then exits the area with a brief 
break for Friday night into Saturday morning. By later Saturday and 
into Sunday a very diffluent upper level flow pattern develops over 
the Pacific northwest with a large plume of moisture being pushed 
into the area in response to the cyclonic flow around a large upper 
level low located in the southern Gulf of Alaska. This pattern will 
bring a good chance for rain and high elevation snow Saturday night 
through Sunday night...snow levels will be quite high...generally 
above 6000 feet. There will likely be a short break in between 
systems early Monday...with the next wave approaching the region 
Monday night and continuing beyond the extended period. With the 
series of systems over the County Warning Area look for breezy or even windy 
conditions for many locations Sunday and Monday...at this time 
southwest winds of 15-25 miles per hour with higher gusts are looking possible 
both Sunday and Monday afternoon. This will be something to continue 
to watch as we draw closer and guidance is able to better hone in on 
the details. Overall expect both high and low temperatures to remain 
very close to the seasonal average throughout the extended period 
for most locations. 77
