Warmer Days & Nights Through Saturday Before a Weekend Cooldown

Temperatures continue climbing through Saturday, with highs running about 3–4 degrees above normal through the end of the week.

Overnight lows will also warm into the upper 70s and lower 80s, so there won’t be as much relief overnight. That means Moderate HeatRisk will continue across the lower desert late this week.

A little extra moisture Thursday could spark an isolated shower or thunderstorm over the Riverside County mountains—right now, only about a 10% chance—but the valley should remain dry.

Mostly we'll just see a small bump up in humidity.

A trough moving into California will bring more clouds and a noticeable cooldown Sunday and Monday, potentially dropping our highs by 6–8 degrees from today’s peak.
