A dangerous heat wave swept across parts of the Western United States, bringing record-breaking temperatures and heightening wildfire risks. A strong ridge of high pressure, identified by meteorologists as a heat dome, settled over a region stretching from Arizona to Montana. The National Weather Service reported extreme temperature forecasts across multiple states. Las Vegas reached a forecasted high of 115 degrees Fahrenheit, marking the hottest temperature of the year and sitting 10 degrees above normal. Phoenix faced expected temperatures of 116 degrees Fahrenheit, while El Centro, California, was projected to hit a record 118 degrees Fahrenheit. In Montana, Great Falls anticipated a record-shattering high of 104 degrees Fahrenheit. Meteorologists warned that overnight lows remaining in the upper 80s and low 90s would significantly increase health risks by preventing physical recovery from the extreme daytime heat. Officials urged residents across the affected areas to stay indoors and maintain hydration. The prolonged heat and dry conditions also escalated red flag warnings and wildfire threats in drought-affected landscapes across California, Nevada, and surrounding states.
