Posted
and last updated

Activity in terms of precipitation will stay relatively quiet through Tuesday before another surge of moisture increases thunderstorm chances Wednesday.

Tonight, marine layer clouds are slowly building across our coastal communities giving the beaches and inland valleys a cloudy and cool start Tuesday. By the afternoon, clouds will mix out leading to quick warming. Daytime highs across the county, except for the beaches, will be up to 5 degrees warmer. Temperatures will hover near average west of the mountains and anywhere from 5-10 degrees above average in the mountains and deserts. We'll also feel a little relief Tuesday as far as humidity levels go.

Another surge of monsoon moisture moves on Wednesday, increasing thunderstorm chances for our mountains and deserts. Storm activity peaks Wednesday afternoon, with pop-up thunderstorms likely continuing to linger into Thursday and Friday. Flash flooding, lightning and hail will be the main threats associated with this activity.

By the weekend, we're looking at cooler and drier conditions, providing slight relief from muggy conditions.

Tuesday's Highs:
Coast: 72-78°
Inland: 82-89°
Mountains: 83-96°
Deserts: 105-110°
