Another Chance of Isolated Thunderstorms Sunday Afternoon

HIGH DESERT, CA. (Pain In The Pass) >> The Southern California Weather Force Forecast calls for mostly sunny skies Sunday with a 20% chance of scattered afternoon and evening showers and thunderstorms. The high will be mid 100s to 110+ degrees. 

A promising weather pattern change begins Monday with temperatures will feel more normal across Southern California before another warming trend returns in the middle of the week.

Today thunderstorms will be high-based and can produce little to no precipitation at times, especially considering the faster movement of storm activity. Each thunderstorm cell will also be capable of producing gusty, erratic outflow winds, gusting upwards of 45 to 60+ mph in region.

The heaviest downpours can have the potential to bring a quick 1-2 inches of rain. The risk for localized flash flooding is low, but cannot be ruled out because the ground is dry and the burn scars areas.

“When Thunder Roars, Go Indoors”
