Southern California will have a respite from hot, dry weather this weekend as colder temperatures sweep in — bringing with them the possibility of scattered rain showers and snow in the mountains.
But the Southland is not out of the woods yet when it comes to fire weather. Warmer temperatures and Santa Ana winds are expected to return Tuesday, according to the National Weather Service.
Light scattered rain showers are forecast for much of the region from Friday night through Saturday morning, according to the weather service. Cooler temperatures are expected in Los Angeles, with overnight lows in the 40s and highs in the 60s on Saturday.
Mountains in San Bernardino and Riverside counties are expected to see a dusting of snow Friday night, with accumulation of up to two inches for communities above 5,000 feet of elevation. A winter weather advisory is in effect in these areas until 10 p.m. Friday, according to the weather service.
The November snow bodes well for the early ski season. Big Bear’s Snow Summit Ski Resort is scheduled to open on Nov. 23.
Mammoth Mountain opened for the season on Friday. Already, there are 12 inches of snow at the main lodge and 26 inches at the summit, with 3 to 5 inches expected to fall throughout Friday afternoon and evening, according to the mountain report.
In Los Angeles and Ventura counties, a wind advisory was in effect from noon to 8 p.m. Friday with gusts of up to 45 mph sweeping through the region, according to the weather service.
Winds are expected to ease during the weekend and then pick back up again next week with the return of the Santa Anas Tuesday through Thursday.
“The gusty Santa Ana winds will likely bring low humidities in the 5% to 15% range during this period … with temperatures rising into the 70s and 80s,” the weather service wrote in its Friday forecast. “As a result, there is still the potential for critical fire weather conditions across portions of Los Angeles and Ventura counties sometime between Tuesday and Thursday.”
These gusts are not expected to be as strong as the mighty winds that fueled the rapid spread of the Mountain fire earlier this month. Those high winds and low humidity rates prompted the weather service to issue a rare “particularly dangerous situation” red flag alert on Nov. 7, warning of “widespread, extreme fire weather conditions.”
Weather service meteorologist Kristan Lund said the decision of whether to issue red flag warnings will likely be made Sunday or Monday, but the danger will be considerably lower than it was two weeks ago.
“We could still have some fires, but the fires won’t grow as strong as they did with the Mountain fire,” she said. “We won’t have as strong of winds to push the fires as quickly.”
