NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Pendleton or 
717 PM PDT Thursday Jul 30 2015 


Update...a few cumulus that developed today over the County Warning Area are 
dissipating with the loss of maximum daytime heating. There are 
thunderstorms developing southwest of the forecast area in mfr's County Warning Area 
otherwise there are some cumulus buildups south of the County Warning Area in mfr's 
and boi's forecast areas. Expect a clear night with mild overnight 
temperatures. Today's highs reached at least 100 in most areas with 
90s in the mountains. Expect a repeat of today on Friday and 
Saturday. However some monsoon moisture will work its way northward 
into the southern portion of the County Warning Area on Saturday which will bring a 
slight chance of showers and/or thunderstorms. It will remain hot 
through the weekend...though not as hot on Sunday. A heat advisory 
is in effect for the lower Columbia Basin...the northern Blue 
Mountain foothills...the Yakima Valley and the eastern Columbia 
River gorge through Saturday evening. There are also some fire 
weather watches/red flag warnings in effect. Please read the fire 
weather discussion below for details. Otherwise forecast is on 
track. 88 


&& 


Aviation...06z tafs...VFR conditions with light winds are expected 
through the next 24 hours. 88 


&& 


Fire weather...high pressure over the area will continue to make 
conditions hot and dry through the weekend. Min rh's will likely be 
below 20 percent across all fire weather zones...with several lower 
elevations falling below 10 percent. Winds tomorrow afternoon are 
forecast to be just strong enough across or/wa639 to create critical 
fire weather conditions. 


In addition the Haines threat will be moderate to high over the next 
few days. Models currently support a high Haines index through 
Saturday over or640 and or642. Due to the West Fork fire mop up that 
continues have decided to issue a red flag warning from today 
through Saturday evening for these zones. 


Models also hint at a high Haines for the Washington 640 and 643 zone over 
the Blue Creek fire as well for tomorrow and Saturday. Confidence is 
not high enough yet for these areas...so will stick with a watch. 


Looks like thunderstorm chances and coverage will be at there best 
from Sunday on into the middle of next week. There is still a slight 
possibility Saturday over central Oregon...but the storms should be 
isolated. Weber

Previous discussion... /issued 445 PM PDT Thursday Jul 30 2015/ 


Short term...tonight through Sunday evening. High pressure will 
dominate the areas weather with dry conditions and well above normal 
temperatures into the weekend. The highest afternoon temperatures are expected 
to range between 100 to 105 degrees mainly over the Columbia Basin 
and the northern Blue Mountain foothills. Hot temperatures will 
persist into Sunday. A heat advisory is now in effect for the lower 
Columbia Basin of both Oregon and Washington...the northern Blue 
Mountain foothills of Oregon and Washington...the eastern Columbia 
River gorge and the Yakima Valley through at least Saturday evening. 


Some moisture may move along the east slopes of the central Oregon 
Cascades Friday and Saturday and an isolated thunderstorms and rain is possible. This 
area of isolated thunderstorms and rain is expected to expand east into the John Day 
Highlands and also into the blue/wallowas Sunday afternoon and evening. 


Long term...Sunday night through Thursday. The weather will become 
more active over the Oregon portion of the forecast area starting 
Sunday night and continue through the week as a trough of low 
pressure sets up over the Pacific northwest. There continues to be 
some disagreement in the models on position of the trough and the 
smaller short waves moving through the trough but it appears there 
will be some chance of showers and thunderstorms from central Oregon 
northeast through southeast Washington each day. The highest 
chance of precipitation and thunderstorms will be on Tuesday from 
the Ochoco Mountains northeast through the blue and Wallowa 
Mountains. Temperatures will be remain well above normal Monday and 
then cool to more seasonal reading through the rest of the week. Ml
