Western US braces for dangerous heat wave with record highs

A dangerous heat wave is expected to bring record-breaking temperatures to the Western U.S. this weekend, prompting officials to urge people to stay indoors and heightening wildfire risks. The National Weather Service forecasts highs of 115°F in Las Vegas and 116°F in Phoenix, with parts of Montana also hitting records. Overnight lows in the upper 80s to low 90s offer little relief. A homeless shelter in Billings opened early to provide relief.
