PHOENIX — Our monsoon storm chances start dwindling beginning today.

After a stormy Saturday and Sunday night the monsoon storm threat looks lower for the Phoenix area today, but we're not in the clear.

Scattered storms may develop along the Mogollon Rim and in southeast Arizona this afternoon. Then there's a slight chance that storms could move back into the Valley this evening.

Storms could produce strong winds and areas of blowing dust, along with dangerous lightning and heavy downpours. The risk for flash flooding near our burn scars will continue to be the biggest threat across the high country.

As high pressure remains near the Four Corners, temperatures will stay sizzling hot!

The Phoenix Metro Area today has hit 110 degrees or more for ten straight days and the streak may continue today.

It's important that you keep heat safety top of mind as Valley temperatures will still top out near 110 degrees all week. Drink more water than usual and try to limit your time outdoors.

Excessive Heat Warnings remain in place through Wednesday for parts of northwest Arizona including Marble Canyon, Glen Canyon and the lower elevations of the Grand Canyon.

Storm chances will continue across the high country each day in the week ahead. For the Valley, we'll see a break from that storm threat on Tuesday before storm chances return Tuesday and each day through the weekend.

Then we could see a bigger temperature drop next weekend as storm chances ramp up even further. Stay tuned for updates as we get closer.
