Area Forecast Discussion...Corrected
National Weather Service Pendleton OR
300 AM PDT Thu Jul 5 2018

Corrected time of issuance to 300 AM PDT

.SHORT TERM...Today through Saturday...Upper low off the Oregon
coast will swing inland across Washington Friday evening. For
today...deep layer southerly flow ahead of the low will result in a
hot afternoon with high temperatures well into the 90s in the lower
elevations and mostly 80s in the mountains. Friday will be a day of
primarily fire weather concerns. As the trough approaches a cold
front will move across the area. Winds will be at least breezy from
the south across portions of central Oregon ahead of the front and
breezy to windy west winds are expected behind the front from the
Columbia Basin Westward during the late afternoon and early evening.
Relative humidities will also be in the teens during peak heating.
Friday evening mainly after 00Z there is still a question of whether
or not there will be any thunderstorm development across northern
Oregon and southern Washington. There remains some elevated
instability in the models particularly in the GFS so have maintained
a slight chance of thunderstorms from 00Z-09Z Friday evening mainly
across the Columbia Basin. After 09Z any thunderstorm activity will
move off to the northeast of the area and the rest of the forecast
looks dry through Saturday. Afternoon highs on Saturday will be
pleasantly cooler with 80s in the lower elevations and 70s
mountains. 78

.LONG TERM...Saturday night through Wednesday...Low amplitude ridge
will yield dry conditions Saturday night through Sunday night. The
ridge then breaks down and gives way to an upper level trough
approaching the coast Sunday night, which pushes a dry cold front
across the forecast area Monday. The front will bring breezy winds to
the region Monday afternoon/evening. The main marine push with the
front occurs in the evening after relative humidity bottoms out and
has begun increasing. Otherwise, dry westerly flow aloft takes hold
Tuesday and wednesday.  Polan

&&

.AVIATION...VFR conditions will persist at all TAF sites for the
next 24 hours. Winds will be 5-10kt.  Polan
