Southern Californians get some weather they can touch, and hear
Rain everywhere, snow in the mountains, thunderstorms at the beach and hail here and there. Welcome, at long last, to the wettish season in Southern California.
The big weather change predicted for this week arrived Wednesday, Nov. 20, following Sunday’s record warm temperatures.
Heavy snow was falling at higher elevations throughout the region, requiring chains in some areas such as San Bernardino County mountain highways, and concern over lightning strikes shut down the piers in Seal Beach and Santa Monica for a brief time.
While Wrightwood received 4 inches of snow and Lake Arrowhead 3 inches, areas at 3,500-4,000 elevation such as the Cajon Pass in San Bernardino County and Frazier Park in Kern County received enough snow to make driving treacherous but not enough to close the 15 and 5 freeways.
For the 24-hour period ending Wednesday afternoon, Huntington Beach received 0.28 inches of rain, Santiago Peak 0.47 inches, Temecula 0.83 inches, March Air Reserve Base 0.27 inches, Lytle Creek Canyon 0.83 inches, Cal State San Bernardino 0.47 inches, Los Angeles International Airport 0.35 inches, Long Beach Airport 0.38 inches, Burbank 0.33 inches and Woodland Hills 0.01 inches.
“Definitely some light, beneficial rain, helping to suppress the fire season there,” said Adam Roser, a National Weather Service meteorologist based in San Diego.
A flash-flood watch for the Inland Empire and eastern Orange County was due to expire at 1 a.m. Thursday. A 30% chance of rain was forecast for Thursday, with the storm moving out late in the day, Roser said. In Los Angeles County, a high-surf advisory for swells of 4 to 7 feet was in effect for west-facing beaches through noon Thursday. A 20% chance of rain was forecast.
“Some of the models are hinting at maybe more precipitation before Thanksgiving,” Roser added.
The storm intensified as a cold low-pressure system from the Gulf of Alaska that triggered rain and snow when its edge moved into the area late Tuesday, weather service meteorologist Casey Oswant said.
Six Flags Magic Mountain in Valencia closed early Wednesday because of the rain. The park said Wednesday tickets will be honored any other day this year.
Temperatures in Southern California were 10 to 30 degrees lower than the day before, according to the weather service.

Chains were required on vehicles starting at Highway 18 and Highway 330 near their junction in Running Springs, and Highway 38 at Angelus Oaks, the California Highway Patrol said.
Oswant said there had been reports of snowfall in Idyllwild in the San Jacinto Mountains in Riverside County, but not in measurable amounts Wednesday morning. But there was enough rain there to damage Highway 243, the bedeviled route from Banning to Idyllwild. It was closed for a few hours on Wednesday because of a washout on the roadway. It reopened at about 5 p.m.
Caltrans said the road was closed from about 6-1/2 miles south of Banning, at Twin Pines Ranch Road, to San Gorgonio Avenue in Banning.
Highway 243 only fully reopened Nov. 1 after months of repairs between Banning and Idyllwild to repair severe storm damage the cratered roadway that was sustained during a Feb. 14 rainstorm that also damaged Highway 74, which connects Idyllwild to Hemet.
Seal Beach officials briefly closed that city’s pier and coastline due to the lightning strikes around 9 a.m., but the areas were reopened when the storm cell moved on. Santa Monica officials took similar action around the same time due to lightning.
In Orange County, a voluntary evacuation order was issued for residents near the 2018 Holy fire burn area, with sheriff’s officials citing the potential for flooding or debris flows. About 100 homes in the Trabuco Creek area were affected by the order, which was lifted at 4 p.m.
Overnight, the storm caused shutdowns due to roadway flooding in the desert areas, including Indio, Vidal Junction, and Bermuda Dunes in Riverside County and Baker and Nipton in San Bernardino County.
