Gusty northwest winds were expected for some areas through Thursday morning with most of the region experiencing fair weather Thursday and Friday, said experts with the National Weather Service in Oxnard.
Many areas will experience 15- to 25-mph winds, they said, and the Antelope Valley and the mountains should see west to northwest winds of up to 45 mph.
The high was expected to reach 60 degrees Wednesday in the Los Angeles region with a low of 40.
The combination of snow, showers, gusty winds and cold temperatures will produce hazardous winter conditions in the mountains through Wednesday afternoon.
Snow levels were still around 5,500 feet, but were expected to lower to about 4,500 feet.
Another low-pressure system may bring unsettled weather in the area for the weekend, forecasters said.
On Saturday, partly cloudy conditions could bring a 20% chance of rain for the Glendale-Pasadena region, according to the National Weather Service.
But it's supposed to clear out somewhat on Sunday in time for the Rose Parade, with lingering clouds and breezy conditions keeping daytime temperatures in the upper 50s.
