An Extreme Heat Watch is in effect for the Phoenix Valley from Monday through Wednesday, with high temperatures expected to reach approximately 111 degrees, according to Arizona's Family meteorologist April Warnecke. The National Weather Service watch will likely be upgraded to a warning as the week approaches, Warnecke reported Friday morning.
The heat arrives after a brief reprieve. Friday's afternoon high of 101 degrees is four degrees below the seasonal average for Phoenix, with morning temperatures in the 70s and 80s. Monsoon moisture is giving way to drier air statewide, and storm chances are dropping sharply, particularly across the Valley. A slim chance of isolated, weak storms remains Friday, with better odds in Western Arizona and the higher elevations of Northern and Eastern Arizona.
The weekend will be dry and progressively hotter: 105 degrees expected Saturday, 109 degrees Sunday.
Monsoon moisture is forecast to increase again by the end of next week, with storm chances possible the following weekend. Warnecke noted that timeline remains uncertain and subject to change.
