Rain, hail and even some snow fell in the Los Angeles Basin on Monday as a cold, unstable front moved rapidly into Southern California off the ocean to remind everyone that winter's lease has not quite expired.
Snow briefly whitened the San Gabriel Mountains and parts of Glendale, Sunland, La Crescenta, La Canada Flintridge and Pasadena as well as the Antelope Valley.
Except in the foothills, the snow was mostly slush and melted away quickly.
The California Highway Patrol warned motorists of slush and snow on the Antelope Valley Freeway at Escondido Summit between Newhall and Palmdale.
Despite earlier forecasts that the rain would not come along until Monday evening, showers began during the morning and--after a deceptive interlude of sunshine--were followed by an upper-level low-pressure area from the Pacific that, in the early afternoon, brought more rain, along with lightning, thunder, hail and snow.
