It's only the first week in May, but already Las Vegas and Phoenix have both reached record-breaking, triple-digit temperatures.
The National Weather Service said Las Vegas had its first 100-degree day of the season on Friday.
It's the earliest that Sin City has crossed over into triple-digit territory since 2004 and only the third time it's happened since 1947.
The Vegas area typically sees its first 100-degree day around Memorial Day, toward the end of the month.
Meanwhile, Phoenix had its first 100-degree day of the season on Wednesday. On Friday set a record with a high of 108 degrees.
The previous record for May 5 in Phoenix was 105 degrees set in 1989.
The city doesn't usually see temperatures that high until early June.
