LAKE ELSINORE, CA —After record high temperatures were recorded in the Inland Empire this week, the heatwave was predicted to break, according to the National Weather Service. Temperatures across the board were expected to drop by at least 10 degrees in some areas, bringing welcome relief to mountain communities where many residents do not have air conditioning.
