We're looking at some nice fall-like weather to round out the week, with slightly below-normal temperatures and breezy afternoons as a trough of low pressure off the West Coast maintains the onshore flow. The flow around this trough will also draw tropical moisture northward into the region this weekend from Hurricane Marie. There should be enough moisture and instability around for scattered showers and isolated thunderstorms, mainly Saturday afternoon through Sunday, but some moisture could linger into next week. Expect under mostly sunny today with highs in the lower 70s, west winds continuing 10-15 mph gusting to 20 mph during the afternoon. Clouds will increase on Saturday with a chance of showers developing during the afternoon. As deeper moisture arrives Saturday night into Sunday, we could experience scattered showers and isolated thunderstorms anywhere in Southern California. Highs will cool to the upper 60s and lower 70s over the weekend, with overnight lows generally in the 50s. Rainfall amounts of around a tenth to a quarter inch are possible, with isolated higher amounts near one half to one inch near thunderstorms. Scattered showers may linger into Labor Day, with drier conditions returning by the middle of next week.
