Dec. 28--Strong northerly winds are expected to pick up in the mountains and foothills of Ventura and Los Angeles counties on Monday night into Tuesday, with gusts blowing up to 40 mph, weather officials said.
The winds will hit Interstate 5 through the Grapevine but will probably not make it into the valleys, said David Sweet, a National Weather Service meteorologist based in Oxnard.
There will also be a 20% chance of rain Monday afternoon, Sweet said. Daytime temperatures will reach about 60 degrees through Tuesday, with nighttime lows in the upper 30s and 40s.
Farther north, weather officials said commuters to Lake Tahoe should expect traffic delays Monday morning because of snow.
"We're expecting another system to move into the region starting this afternoon through tomorrow morning," according to Scott McGuire, a NWS meteorologist based in Reno, Nev. "It's not a big storm or anything, particularity compared to what we saw in the last couple of weeks."
Up to 6 inches of snow is expected higher up in the Sierras. No significant winds are expected with this storm system. "It'll be a quick, cold moving kind of snow event," he said.
The Lake Tahoe region is expected to be clear by New Year's Eve, with a high about 30 degrees and a low about 16 degrees.
"It'll still be cold, but sunny," McGuire said. "Travel-wise, people coming in for New Year's won't be dealing with travel delays from snow."

In Monterey and the Bay Area, a cold front this weekend helped break record-low temperatures. Oakland Airport recorded a low of 30 degrees Sunday, which broke the 1956 record of 31 degrees.
"Usually this time of year, we have temperatures in the mid-40s to upper-40s," NWS meteorologist Larry Smith said in Monterey. "So it's pretty darn cold for us."
Weather officials said there is cold air moving across much of Northern California. In the Sacramento Valley, a weak weather system is expected to move in Sunday night and could generate about 2 to 4 inches of snow for the northern Sierra and some "minor amounts of dusting in the foothills," said Karl Swanberg from the NWS station based in Sacramento.
About an inch of snow could also reach the Shasta Lake area, Swanberg said.
