Low pressure off the West Coast continues to pump tropical moisture northward into Southern California from the remnants of once tropical storm Mario. A large swath of moisture moved through overnight and this morning, dropping around a quarter to half inch of rain across the region, mainly San Diego County north through our inland areas, with lesser amounts to the west. Expect mostly cloudy skies today with showers and thunderstorms possible across all of SoCal, cooler locally with highs in the 60s. Some storms may become strong to severe and produce heavy rainfall, strong winds, frequent lightning, and hail, with localized flooding possible, travel with care. Showers and storms will taper off a bit this evening as the deeper tropical moisture shifts north of the area. We'll likely transition to more of a monsoon-type pattern with diurnally driven convection over the mountains and deserts Friday through the weekend. Daytime highs will remain in the 60s on Friday, warming back into the 70s over the weekend with overnight lows generally in the 40s. Conditions look to dry out early next week as this whole system finally exits the region with nice fall weather expected throughout next week.
