Memorial Day weekend will be cool, windy and foggy in Southern California, with sunnier weather expected to return by Monday, forecasters say.
According to meteorologist Mike Wofford of the National Weather Service in Oxnard, a sharp increase in onshore winds from Friday will trigger the cooling trend for most of Southland, while other areas inland and in the valleys will remain warm.
A low-pressure system moving across British Columbia in Canada is responsible for lower temperatures in southern California, Wofford said. Scattered fog is expected to linger along the coast and nearby towns well into the afternoon, with temperatures ranging in the mid-60s to low 70s.
A similar forecast is expected across the region on Saturday and Sunday. Further south, the National Weather Service warns drivers of dense fog at higher elevations where the marine layer causes poor visibility.
Overnight lows will dip into the mid-50s on Friday evening, and a gradual warming trend will arrive in coastal communities on Sunday, according to the weather service. Travelers heading east for the holiday weekend will find warmer temperatures.
In Palmdale, Lancaster and other inland areas, temperatures will be 10 to 15 degrees warmer with strong winds blowing at 15 to 20 mph and up to 40 mph in the mountains, desert foothills and under the passes on Saturday and Sunday, according to forecasters.
The strongest winds will blow on Sunday and create high fire danger mostly over deserts, according to meteorologist James Brotherton of the National Weather Service in San Diego.
“It will keep the fire danger high for sure,” Brotherton said.
Those strong winds will eventually subside by Monday as temperatures begin to warm again, according to the weather service. Temperatures are expected to reach the low 80s by Tuesday.
