The Western United States continues to bake in unrelenting heat. Record low temperatures have been broken, but not the cool record lows. The record lows broken are for the warmest low temperatures for areas like Phoenix and Las Vegas. In fact, Las Vegas has not cooled below 90 degrees - even at night - for three days. Las Vegas warmed to 117 degrees, which is the hottest temperature on record in the city.
The Associated Press says heat has been more deadly in recent times than other weather extremes. The abnormally warm overnight temperatures are not allowing people's bodies to recover from the intense heating of the day, making conditions even more dangerous.
Heat is normal in the Southwest during the summer. This hot period is abnormally hot even for the Southwest. The eastern U.S., on the other hand, has actually been cool and breaking record LOW temperatures.
