Forecasters say temperatures will be below average beginning today, with light rain possible tonight, Thursday and through the weekend.

For now, at least, the forecast is clear for Saturday night’s Belmont Shore Christmas Parade along Second Street, which draws an estimated 50,000 spectators and more than 200 parade entries.

There’s a chance of light rain after 11 p.m. Saturday, with a high temperature of 65 degrees that day and a low of 50 degrees. The parade begins at 5:30 p.m. and concludes at 9 p.m.

The rest of the week, however, keep your umbrella handy.

The strongest chance of rain is Thursday night, at 80%, according to the National Weather Service.

Los Angeles County officials also issued a cold weather alert for parts of the Southern California region, effective through Thursday.

Some mountain areas could get 2 to 4 inches of rain this week, according to the NWS. Snow levels are expected to remain above 6,000 feet.
