Polar vortex it is not, but a storm system moving down the coast was expected to bring some rain and possible thunderstorms to parts of Southern California on Monday.
A cold front (read: highs around 60) was expected to move into Ventura and Los Angeles counties overnight, bringing scattered showers and the possibility of a tenth to quarter of an inch of rain in coastal areas, according to the National Weather Service in Oxnard.
Mountain areas above 5,000 feet could see one to three inches of snow, forecasters said. There is a slight chance of thunderstorms that could bring an additional half inch of rain, according to the weather service.
A winter weather advisory was issued through 8 a.m. Monday, warning of snowfall and scattered showers affecting driving conditions on the Angeles Crest Highway and Interstate 5.
Skies were expected to clear by Monday afternoon, but temperatures were to remain a few degrees below normal through Wednesday.
