After a weekend of record-breaking heat, Southern California can expect light to moderate rain and even some snow in the mountains starting Tuesday.
A cold low-pressure event has the potential to bring .25 to .75 inch of rain in Los Angeles County and .1 to .5 inch of precipitation to Ventura County in the first rainfall of the season, the National Weather Service said.
In the Inland Empire, "heavy rainfall" can bring up to 1 to 2 inches of rain Tuesday afternoon through Wednesday morning, with showers lingering into Thursday.
It will be cold enough for snow in areas at elevation 5,500 feet or higher, the Weather Service said.
Are you prepared for 1 to 2 inches of rainfall? Yes there is the potential for heavy rainfall developing Tuesday afternoon through Wednesday morning - showers into Thursday, heaviest across Inland Empire and San Diego County, and cold enough for snowfall down to 6000 feet #CAWx

This can result in slick roadways, flooding and a slower commute, the agency warned.
The cold and damp forecast follows record heat in portions of Southern California over the weekend.
Temperatures in downtown L.A. reached 92 degrees Fahrenheit on Sunday, beating the daily high record set in 2008 by 1 degree, according to NWS. Long Beach had a high of 91 degrees, exceeding the 2008 record by 4 degrees.
Meanwhile, Camarillo's 94-degree high on Sunday beat the 92-degree record set in 1932. Temperatures at Los Angeles International Airport reached 93 degrees, surpassing the record in 1949 by 2 degrees.
Burbank, Lancaster and Santa Barbara didn't break heat records, but nearly did, forecasters said.
Fire weather conditions that threatened the region during the weekend are expected to persist Monday, when temperatures can hit the 80s to the low 90s. Humidities can drop as low as 8 to 15% amid 15 to 30 mph wind gusts blowing from the northeast-east, according to NWS.

Unfortunately you can keep your umbrellas☂️ at home this week in the #BayArea. Aside a very, very minor chance of light showers midweek, dry conditions are expected. You'll have to go to SoCal or Phoenix to see measurable rain🌧️. Here's a loop of total forecast precip. #CAWx pic.twitter.com/sj5RQUScJg
