The calendar shows it’s almost Memorial Day — typically beach weather in Southern California — but gray skies are signaling that unusually chilly temperatures and rain will stick around a bit longer during a month that has already broken precipitation records. The forecast this month has been a doozy in California with rain, hail and snow falling across much of the Golden State two months after the end of winter. Large swaths of the state, including parts of Los Angeles, have seen two to five times more precipitation than is normal for this point in May, according to the National Weather Service.
