A nice push of low clouds up the Columbia River this morning, models did really well with showing them coming up a bit past Kelso/Longview. Interesting that they’ve been all north/east of the Columbia River (okay, maybe a mile or so over it in some cases). Such a thin marine layer will evaporate quickly into sunshine up there today. Tomorrow at the least we should see the clouds push down east of the West Hills all the way down into the lower elevations of Clackamas county. The cooling trend is definitely on.
A nice shortwave disturbance showing up on the image as well moving north through Eastern Oregon, setting off early morning thunderstorms over there.
