LOS ANGELES (CBSLA) — Following a week of summer-like heat, the Southland underwent a dramatic cool-down Tuesday, with rain, hail and snow falling in some areas.
National Weather Service forecasters said the changing conditions were thanks to a cold low-pressure system that moved into the region from Northern California.
"Scattered showers are expected through tonight across Los Angeles County with low snow levels. Gusty winds will continue in many areas through tonight as well," according to the NWS. "A warming trend will develop across the region for the latter half of the workweek as high pressure aloft builds in the west of the state."
CBSLA Meteorologist Amber Lee said thunder and lighting were expected near the foothills and mountains.
By Tuesday afternoon, heavy rain with lightning and small hail fell in Pasadena, West Los Angeles, Anaheim, Simi Valley, Camarillo, Burbank and Glendale.
According to the NWS, the weather will impact Alhambra, Temple City, Altadena, and Sierra Madre through 5 p.m. Commuters along Hwy 215 were told to use headlights and use caution.
Lightning caused the closure of all Los Angeles County beaches. Swimmers and surfers were being cleared from the water, and people were being advised to leave beaches and seek shelter until the storm passes.
By 6:30 p.m. the beaches had reopened.
By mid-afternoon, light snow was already being reported along the Grapevine, dramatically slowing traffic in the northern reaches of the county.
By late Tuesday afternoon, the snow level dropped to about 2600 feet in the Antelope Valley. There was also a half-foot of snow in Pear Blossom at 3500 feet.
A wind advisory will be in effect until 10 p.m. in the Antelope Valley, where gusts of up to 45 mph are possible, and until 9 p.m. in the coastal area, with 35 mph gusts in the forecast.
A winter weather advisory will be in effect until 10 p.m. for the Los Angeles County Mountains, excluding the Santa Monica range.
The low-pressure system is expected to leave the area by Wednesday, bringing warmer and drier conditions.
