Southern California mountains have a dusting of new snow following the passage of a weak weather system over the weekend.
Cold air arriving in the wake of the system has dropped temperatures into the 30s in many areas early Monday, and forecasters say the day's highs will remain below normal.
Small craft advisories are posted for hazardous seas and gusty winds along much of the coast.
A warm-up is expected to begin Tuesday as a ridge of high pressure brings offshore flow. The uptick in temperature will last into the weekend, the National Weather Service's Andrew Rorke told KPCC.
On Tuesday, Southern California will see an eight to 12 degree spike, and up to another six degrees on Wednesday. Thursday will be the hottest day of the week, with temperatures reaching anywhere from eight to 16 degrees above normal.
“It’s not record-high, we often do get very warm periods in March, but it is much warmer than a typical March week would be,” he said.
Sunday's front left a trace of rain in downtown Los Angeles, which has collected 18½ inches since the start of the water year on Oct. 1. That's 7 inches more than average by this time.
