.DISCUSSION...Showers are moving into the region as of this
afternoon with the passage of a frontal boundary. There remains
high confidence in wetting rains from the Columbia Basin through
Blue and Wallowa Mountains (90%). Winds increase tomorrow,
becoming breezy from a westerly direction. A wind advisory has
been issued for the lower Columbia Basin of Oregon due to winds
gusting around 45-50 mph with moderate to high confidence
(60-70%). As the main portion of the low then moves into the
region, instability will rise and a chance of showers and possibly
thunderstorms is expected, with low confidence (10-30%). Storms
are not expected to be strong, and should mostly contain a chance
of lightning and locally breezy winds. Finally, lowering snow
levels will promote a chance of mountain snow as temperatures drop
tomorrow, though amounts will remain light and quickly melt off
as temperatures recovering by the next day.
***Thunderstorms imply strong gusty winds***
***Winds are 20 foot 10 minute averages***
***CWR-chance of wetting rain 0.10 or greater***
