Cool and breezy conditions are expected to give way to another rainstorm later this week, but forecasters say it should be mostly clear and brisk by New Year’s Day and the all-important Tournament of Roses Parade in Pasadena.

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.

A winter weather advisory was issued for Thursday until 10 a.m., with blistery snow showers expected on north facing mountain slopes in Los Angeles and Ventura counties.

Snow levels had also dropped to around 3,000 feet, according to the National Weather Service, which also warned of icy road conditions on the Golden State (5) Freeway near the Grapevine.

As the weekend approaches, another low-pressure system may bring more unsettled weather, including a 40% chance of rain for the Glendale-Pasadena region on Saturday, according to the National Weather Service.

It’s supposed to clear out somewhat on Sunday in time for the Rose Parade on Tuesday, with lingering clouds and breezy conditions keeping daytime temperatures in the upper 50s.

And for those planning to camp out overnight along the parade route, bundle up. The overnight lows on New Year’s Eve are expected to be in the low-40s.
