The heatwave is already underway, with hotter temperatures for Thursday and Friday.

Dangerous heat is expected to continue impacting our mountains with a Heat Advisory already in effect until Friday night at 9pm. The advisory will expand into our inland communities at 10am Thursday, also in effect until 9pm Friday.

Monsoonal flow is also back, we haven't seen much today but the chance for widespread activity does look better for Thursday. The best chance will be in our mountains, and deserts. Inland communities could also see a passing shower or thunderstorm with a 20% on Thursday. The chance of storms on Friday will be more isolated in nature targeting our mountains and deserts.

Moisture retreats the area over the weekend, but the heat lingers. Hot and dry conditions are a concern with elevated fire danger expected into early next week.

Temperatures should begin trending down on Tuesday with mostly sunny skies.

Coast: 75-84°
