It’s here. After weeks of planning and fretting, today is eclipse day. Clark County isn’t in the path of totality for the first total solar eclipse to pass over the United States since Feb. 26, 1979, but will see about a 99-percent partial eclipse. The weather looks like it will cooperate. Today is expected to be sunny with a high of 87 degrees, David Bishop, meteorologist for the National Weather Service in Portland, said. “There might be a cloud or two up there, but nothing substantial to impede viewing the eclipse,” he said. Temperatures typically drop during an eclipse, but Bishop said there probably won’t be that extreme of a temperature change in the Clark County area. “Five degrees is not out of the question,” he said.
