SAN BERNARDINO • A winter weather advisory has been issued through Thursday night, with low temperatures, high winds and the possibility of snow in the Cajon Pass on Thursday, according to the National Weather Service.
“There will be a drastic change to the weather after a nice day Wednesday,” explained NWS meteorologist Alex Tardy. “Snow levels are going to abruptly fall.”
The snow level will drop to 3,000 feet by Thursday afternoon and 2,500 feet by Thursday night, according to AccuWeather.com.
The Cajon Pass is likely to get an inch of snow Thursday morning followed by snow showers into the evening, Tardy said.
Most High Desert cities will see precipitation with the possibility of a dusting of snow, according to Tardy. The foothills of the San Bernardino mountains could get an accumulation of one to two inches of snow, according to the NWS.
Strong winds with gusts up to 60 mph are expected throughout the Victor Valley into the weekend with a high wind warning in effect until 10 p.m. Thursday, according to a AccuWeather statement.
Motorists are advised to be prepared for slippery roads and limited visibility from blowing dust, sand and snow, especially along Interstate 15. Authorities also warn that this weather could be deadly for unprepared campers or hikers.
“The coldest air of the season will settle over much of California Friday and Saturday,” according to Expert Senior Meteorologist Ken Clark of AccuWeather.
Temperatures are expected to be the lowest yet this winter, with projected lows in the mid to low 20s and upper teens, according to a AccuWeather forecast.
Another cold front is expected to come in Sunday night, bringing the possibility of more snow to the Cajon Pass, Tardy said.
Decisions are made about closing highways based on safely and the number of collisions in inclement weather rather than a specific quantity of snow or ice, according to CHP spokesperson Matt Hunt. For current information on highway conditions, call Caltrans at (800) 427-7623.
