MOST ACCURATE FORECAST: Slight chance of monsoon storms in the Valley

While the threat of thunderstorms looks low in the Valley, we aren't completely in the clear.

There's a slight chance of showers and thunderstorms overnight and another slight chance Saturday afternoon and evening.

Air quality is also a concern. The Valley is under an Ozone Health Watch Saturday and an Ozone High Pollution Advisory on Sunday. So, if you have any kind of respiratory condition, you may want to limit your time outside or you could have difficulty breathing.  

By Sunday, Valley storm chances clear out completely and temperatures start to get much hotter.    

Valley highs will be topping out between 110 and 116 degrees early next week. 

An Excessive Heat Warning is now in effect Monday, Tuesday and Wednesday for the entire Phoenix metro. This heat alert stretches across most of southern and western Arizona, too. 

With records sitting near 115 degrees early next week, we could tie or break a few. So, Monday, Tuesday and Wednesday will be ABC15 Weather Action Days. 

Take action to protect yourself from heat related illnesses. Stay inside as much as possible and stay hydrated.
