PHOENIX – Incoming thunderstorms are expected to drop the temperatures by double digits in metro Phoenix and also drop up to an inch of rain in some parts starting early next week, forecasters said Friday.

On the heels of a two-day excessive heat warning and Friday high predicted at 112 degrees, the National Weather Service said temperatures could fall to 98 degrees Monday and Tuesday.

The average high in the Valley for July is 106 degrees.

“We can’t rule out seeing upper 90s,” James Sawtell, a meteorologist with the Phoenix weather bureau told KTAR News 92.3 FM, “[but] we’re only looking at a high of 101 by Sunday and the rest of the week is going to range from 100 to 103 degrees.”

Those lower temperatures will be brought on by cloud cover and rain.

The chance of rain in the Valley was 60% on Sunday night into Monday morning, followed by 40% by Tuesday and 30% Wednesday and Thursday.

“Phoenix could see three-quarters of an inch to a little over an inch … from very late Sunday to about early Wednesday,” Sawtell said.

“Rainfall should be fairly significant for several locations,” he added.

“Some places will certainly get more than others because of the spotty nature of locally heavy thunderstorms in the monsoon season.”
