An easterly wave tracking westward across Arizona will slowly move into our area later Sunday into Monday, possibly bringing more widespread showers and thunderstorms across much of Southern California. An abundance of cloud cover could limit afternoon convection, but with an upper-level low in play, storms could fire off at any time, just about anywhere. Mostly cloudy skies. Mostly cloudy skies overnight with a few showers or sprinkles possible, light winds with lows in the 50's. Partly to mostly cloudy skies on Sunday with scattered showers and thunderstorms possible, cooler with highs in the 70's. We'll have our best shot and showers and storms Sunday night into Monday as this disturbance passes through the region. Any thunderstorms that do fire up will be capable of heavy rain, gusty winds, frequent lightning, and small hail. This wave will pass west of us by Tuesday bringing a return to the more traditional diurnally driven thundershowers. Isolated afternoon thunderstorms will remain possible all week as temperatures remain near average. Another surge of moisture could bring an increasing chance for showers and storms by next weekend.
