Thursday brought slightly warmer temperatures, and that warming will continue through the next few days. Even with the warming, highs mostly stayed cooler than normal.

Labor Day weekend will bring temperatures into the mid-70s to low 80s at the coast, low to mid-90s inland, mid-80s in the mountains and between 105 to 110° in the deserts.

The heat peaks Sunday though Saturday and Monday will be nearly as hot. There is moderate heat risk for areas east of the coast this weekend.

The monsoon starts to pump in higher humidity and high clouds starting Sunday when we'll see a very slight chance for a pop-up shower or thunderstorms; a better chance for monsoon storms early next week mainly over the mountains and deserts.

Friday's Highs:
Coast: 73-78°
Inland: 78-88°
Mountains: 78-93°
Deserts: 100-106°
