The heatwave continues through the weekend with humidity increasing on Sunday.

An Excessive Heat Warning is in effect for the deserts until 9pm Sunday. Temperatures between 110 to 118 degrees. The overnight temperatures stay close to 90 degrees, with very little break during the duration of the warning. The dry heat will keep elevated fire danger in place until Saturday, then we shift gears to hot and humid starting on Sunday.

Near the coast temperatures will hover in the low 80s through the weekend, the water temperature is in the low 70s. The swell will range from 1 to 3 feet with low risk of rip currents, making it so much better for swimmers.

Monsoonal moisture is set to returns as high pressure shifts to the east, and brings back a southeasterly flow. Possible showers and isolated thunderstorms will be in the forecast from Monday until Thursday, due to the nature of monsoonal moisture heavy rain can't be ruled out. The best chance will be in the mountains and deserts.

Temperatures will drop slightly next week, but the humidity won't help to make a difference.

Near the coast, we will begin to see patchy low clouds and fog returning next week. The marine layer will have a better chance at settling near the coast, allowing temperatures to cool down and return to normal mid to late week.

Friday's Highs:
Coast: 77-85°
Inland: 88-103°
Mountains: 90-101°
Deserts: 111-117°
