Showers and thunderstorms will be possible, with areas of heavy rain. Palomar Mountain picked up 1.77 inches of rain.

Monsoon moisture is back and the chance for heavy rain with isolated thunderstorms will continue tonight, and again Wednesday afternoon and evening. Showers could last into early tomorrow morning, potentially reaching some coastal communities.

A Flash Flood Watch will be in effect for the mountains, now extended to our deserts until 8pm Wednesday. Heavy rain, strong winds, small hail, and lightning will be possible with any thunderstorm.

The chance for storms subsides Thursday and Friday, the air will be slightly drier. A storm or two could develop but it won't be as widespread. Another surge of moisture and instability will bring a better chance once again over Saturday through Monday.

In addition to the humidity, it will also be hot with temperatures mostly in the 90s inland and 80s for the warmer coastal areas.

Low clouds and patchy fog will impact coastal communities and some inland areas each morning, with monsoon clouds each afternoon.

Wednesday's Highs:
Coast: 75-80°
Inland: 83-93°
Mountains: 85-96°
Deserts: 101-106°
