PHOENIX — The heat cools down a bit this week as our chances for monsoon storms ramp up.

High pressure is east of the state, taking the edge off of our heat. It's also opened up a surge of monsoon moisture from the south, ramping up storm chances across Arizona.

Flood Watches are now in effect through Tuesday for the Valley along with central, western and southern Arizona.

Gusty winds, lightning and heavy downpours will be the main threats with any storms that move through. There's also an increased risk for flash flooding near our wildfire burn scars.

With these scattered to widespread thunderstorms some spots could see between a half of an inch and an inch of rain over those 3 days.

For the high country expect anywhere from one to two inches of rain over the next few days.

As storm chances increase, temperatures will drop dramatically. Expect Valley highs in the upper 90s by Monday and Tuesday.
