The U.S. in July set a new record for overnight warmth
Talk about hot nights, America got some for the history books last month.
The continental United States in July set a record for overnight warmth, providing little relief from the day's sizzling heat for people, animals, plants and the electric grid, meteorologists said.
The average low temperature for the lower 48 states in July was 63.6 degrees (17.6 Celsius), which beat the previous record set in 2011 by a few hundredths of a degree. The mark is not only the hottest nightly average for July, but for any month in 128 years of record keeping, said National Oceanic and Atmospheric Administration climatologist Karin Gleason. July's nighttime low was more than 3 degrees (1.7 Celsius) warmer than the 20th century average.
