PORTLAND, Ore. -- Eclipse watchers shouldn't be too concerned with the clouds they might be seeing Sunday evening, KGW's Brian Brennan said.
"These high clouds are associated with a weak system passing by to our north," he said Sunday afternoon. "The main area to be concerned about low clouds getting in the way of eclipse viewing is the coast. Clouds are consolidating offshore and will be moving in tonight."
He said a shallow marine cloud layer could move in north of Pacific City along the coast Monday morning.
"Pressure gradients suggest the clouds will be less thick and may even start to clear along the central coast," Brennan said. "That being said, though, views on the beach may be spotty."
Clouds will also try to make their way along the Columbia River, with morning clouds very possible around Kelso and possibly in the Portland metro area. But they should be pretty scattered and won't effect views of the eclipse too much.
"South towards the path of totality in the Willamette Valley there should be fewer clouds and good views of the eclipse," Brennan added. "The best place to be to get away from clouds will be east of the Cascades. Smoke may be a slight issue, but probably won't be thick enough to effect viewing conditions."
