Chance of Isolated Thunderstorms Today

HIGH DESERT, CA. (Pain In The Pass) >> Saturday will feature a blend of sun and clouds, with a few pop-up thunderstorms in the afternoon. It will be hot and humidity will be up, with highs in the 100s to mid-110s.

Southern California Weather Force is predicting isolated to scattered showers and thunderstorms to sweep across Southern California Saturday, July 13. The main threats are dry lightning, and gusty winds, according to SCWF.

It looks like the best chances will be mainly in the early to late afternoon hours today. Today’s strom chances are right around 30% and tomorrow’s chances are at 10%.

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.
