Low pressure off the West Coast continues to pump tropical moisture northward into Southern California from the remnants of once tropical storm Mario. This will bring widespread showers and thunderstorms to the entire area today. Deeper moisture will move this morning with showers increasing in coverage and intensity from south to north. Expect mostly cloudy skies today with showers and thunderstorms likely, cooler with highs in the 60s. Some storms may become strong to severe and produce torrential rainfall, strong damaging winds, frequent lightning, and hail, with localized flooding possible, travel with care. Showers & storms will taper off a bit Thursday evening in Friday as this plume of moisture lifts north of the area. We'll likely transition into more of a monsoon-type pattern with diurnally driven convection over the mountains and deserts. Daytime highs will remain in the 60s through Friday with overnight lows in the 40s. The snow level will mostly stick above 12,000 feet, but could dip low enough Thursday night with any lingering moisture for a dusting up on San G. Otherwise, expect slightly warmer temperatures over the weekend with a chance of afternoon thundershowers continuing. Temperatures will top out in the lower 70s by Sunday as overnight lows remain in the 40s. Our forecast looks dry next week as we officially head into fall, but there is another tropical system off the coast of Mexico that bears watching. At this time, it looks like it's headed out to sea, bringing minimal impacts, if at all.
