A hard freeze in extreme northern Los Angeles County
produced an overnight low of 24 degrees at Sandberg today — the coldest on
record — and temperatures early Thanksgiving Day are also expected to be in
record range.
The old record in Sandberg, which is in the mountains near the Kern
County line, was 27 degrees set in 1952, according to the National Weather
Service.
The overnight low in downtown Los Angeles is forecast to be 41 degrees,
five degrees shy of the record of 36 degrees, she said.
Lows around Orange County are forecast to range from 41-46 degrees.
Flurries could fall in the Santa Ana Mountains, where forecasters predict a
slight chance of precipitation.
In the Antelope Valley, a freeze warning will be in effect from 11
tonight to 9 a.m. Thursday, according to the NWS.
A freeze warning means temperatures below 28 degrees for at least two
hours are likely. These conditions can kill crops and other sensitive
vegetation. Precautions should be taken to protect outdoor plants and crops,
Bartling said. Vulnerable animals and pets should be kept sheltered or indoors.
No freeze warning was expected in Los Angeles, she said.
“The cold air is very dense, it stays close to the ground, so the
mountains will serve as a barrier of sorts,’ NWS meteorologist Curt Kaplan
said. “It will be down in the teens overnight in the Antelope Valley, but not
that cold on this side of the mountains.’
A cold and dry air mass beneath strong northerly flow is moving toward
Southern California behind a departing cold front, Kaplan said.
“It’s on its way, and we will see its effects tonight,’ Kaplan said.
Lows in the high desert are predicted to range from 16- 22 degrees.
Despite the cold overnight temperatures, Thanksgiving Day should be
sunny and warm in the metro area, with highs in the mid 60s. Winds will be out
of the northeast at 15-30 mph, with stronger gusts possible below canyons and
passes.
