The heat is here to stay for a little bit longer, and monsoonal moisture will increase the threat for thunderstorms starting on Sunday.

Low clouds and patchy fog will return tonight near the coast, with some clouds traveling into western valleys. Sunday will be mostly sunny, but as you look east will begin to see towering clouds as thunderstorms begin to develop. Monsoon thunderstorms will bring the risk of heavy rain and flash flooding, so stay vigilant to the changing conditions.

The chance for storms will last from Sunday through Wednesday. Peak activity will be over the mountains and deserts, but a few storms could move west into the valleys and potentially all the way to the coast. The best chance for storms to travel outside of the mountains westward will be on Monday.

Next week will start out hot and humid, but temperatures will drop below average on Wednesday, with drier conditions for the second half of the week.

Sunday's Highs
Coast: 75-80°
Inland: 84-97°
Mountains: 89-96°
Deserts: 104-109°
