Monsoon storm chances increasing this weekend

PHOENIX - We're back in monsoon mode this weekend as our storm chances ramp up again. 

Valley storm chances will be at 30 percent over the weekend, meaning we could see scattered showers and thunderstorms both Saturday and Sunday. 

Any storms that develop could produce heavy rain and flooding, so remember to stay away from flooded washes and roads. 

There's also the risk of high winds, blowing dust and dangerous lightning, too. 

As monsoon moisture pumps in, humidity will be much higher over the weekend but our actual temperatures will drop.

Highs will only reach the upper 90s Saturday and Sunday with early morning lows across the Valley in the upper 70s to low 80s. 

We'll be back to just a 20 percent chance of spotty storms early next week as the triple digits return.
