Monday marked the first day of a heat wave expected to make its way through the Valley.
An excessive heat watch was issued for Monday through Wednesday. Highs could range from 114 to 118 degrees.
Overnight lows Monday could be 90 or 91 degrees, the National Weather Service said.
But the heat was not expected to hang around for long.
“At least through Wednesday, heat’s going to be the big thing,” Bianca Hernandez with the National Weather Service told KTAR News 92.3 FM.
“As we go into the end of the week, we actually start to see an increase in monsoonal moisture.”
