.DISCUSSION...A weather system currently bearing down on the
Pacific Northwest will bring shower and thunderstorm chances
primarily to the Washington Cascades during the day tomorrow.
There is a very slight chance that a stray cell forms off the
Oregon Cascades and impacts the site, but confidence in this
occurring is very low. Outside of storm chances, expect generally
light northwest to north winds during the day and gradually
cooling conditions, leading to improving RH recoveries over the
coming days.
