Scattered showers, with a chance of thunderstorms and hail, were still in the offing Tuesday across Los Angeles, along with possible heavy snow in the Antelope Valley and local mountains, forecasters said.
There is a 40 percent chance of rain across the Southland this evening, with a slight chance of thunderstorms after midnight.
A very cold low-pressure system was moving slowly south off the California coast today and was expected to bring heavy snow to the Antelope Valley and county mountains, according to the National Weather Service. Snow levels are forecast to drop to 2,000 feet, which should result in an accumulation of snow down to the valley floor.
Snow is expected to begin later tonight and continue through Wednesday morning, with an accumulation of between six and 12 inches predicted. That's more good news for the ski slopes, which just got their first covering of the white stuff between Sunday night and Monday.
The NWS has also issued a winter storm watch for Los Angeles County, which is expected to remain in effect from late tonight to Wednesday evening. A winter storm watch means there is a potential for a combination of significant snow, strong winds and dense fog that may impact travel plans.
The Weather Service is predicting that highs will only hit the mid-50s this afternoon, with lows ranging in the 40s and even the 30s Tuesday night.
Monday's heavy rains broke some local records across the Southland. Long Beach had 1.38 inches. Its previous record on this date was six-tenths of an inch in 1988. Los Angeles International Airport had 1.89 inches, with a previous high of 1.04 inches in 1957. Burbank had 1.44 inches, with a previous high of 1.37 inches in 1957.
