Following a week of summer-like heat, the Southland underwent a dramatic cool-down Tuesday, with some light rain even falling in select 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.
“Colder temperatures, strong northerly winds and a chance of rain and mountain snow showers are possible through (Tuesday night),” according to the NWS. “A warming trend will develop across the region for the latter half of the work week as high pressure aloft builds in west of the state.”
Forecasters noted that while some “sprinkles and light showers” occurred across the area, there was “little if any measurable rain.”
“There is some decent cold air with this low, so an isolated thunderstorm can’t be ruled out across L.A. County later this afternoon and evening, but mainly it will be just scattered light showers with some brief bursts of moderate to locally heavy rain,” according to the NWS.
The snow level is expected to drop to about 4,000 feet by late Tuesday afternoon, meaning there will be a slight chance of some light snow accumulating on the Grapevine, and “a few inches of snow” in the mountains.
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 will move out of the area by Wednesday, with warmer and drier conditions on tap for Thursday, according to the NWS.
