Pattern Change Ahead

Patterned altocumulus clouds near Los Angeles

Computer models and other tools continue to forecast a shift to an “El Nino like” upper flow pattern next week that could result in an extended period of wet weather in Southern California. I’ll be updating Southern California Weather Notes on Wednesday with additional info.

The photograph of patterned altocumulus clouds is from this afternoon’s trail run along the northern boundary of Ahmanson Ranch, near Los Angeles.
