A winter weather advisory is in effect Thursday morning for Southern California's mountains, where some residents are waking up to snow and chilly temperatures.
The region is on the southern edge of a low pressure system that's producing rain, wind and snow during the first week of November. Temperatures will again run below normal Thursday, when more snow is expected in the mountains.
The winter weather advisory will be in effect until 10 a.m.
Chain restrictions were in place for the San Bernardino Mountains, including routes 18, 38 and 330.

"You think this morning is cold, tomorrow is going to be even colder," said De Leon. "Take the time throughout the day to protect that vegetation that is sensitive to this big drop in temperatures. And, also, bring the pets inside."
Temperatures will warm into the weekend, when highs will be in the 70s for most of the region. Another cold snap and round of rain are in next week's forecast.
