LAS VEGAS—The Southwest United States continued to bake Saturday, and weather forecasters kept warnings in effect for excessive heat in Arizona, Nevada, and desert areas, at least through the weekend.
High temperature marks didn’t fall Saturday, but Phoenix reached a sweltering high of 115 degrees F (46 degrees C) for the day and Las Vegas hit 111 degrees F (44 degrees C). Both were three degrees shy of records for the date, forecasters said.
