 National Weather Service meteorologist Mark Chouinard says the blistering heat won't end anytime soon for California and Oregon. The heat in the west in particular looks to persist through the week. And if you look at the extended outlooks, the overall pattern favors above normal temperatures even going out a couple of weeks from now. Chouinard says temperatures will be dangerously hot for some celebrating the 4th of July across the U.S.
