SoCal Braces For 'Dramatic' Cooldown After Historic Heat Wave

LOS ANGELES, CA — The Southland will trade out unseasonably hot weather for "drastically" cooling temperatures, the National Weather Service said on Monday.

A winter storm was expected to arrive on Tuesday, which will bring showers and winds, especially in the mountains above 3,500 feet.

A dramatic temperature change has already occurred in Southern California, with many parts of the coast feeling temperatures 15 to 25 degrees lower than Sunday.

"Our dear friend the marine layer is keeping things especially chilly along the central coast," weather service officials said.

A heat advisory, set in many areas of Southern California through the weekend, expired on Sunday evening.

The return of onshore flow Monday brought some cooling of highs in the 70 and lower 80s, with more dramatic cooling expected to occur on Tuesday.

California weathered a heat wave with eight locations in the region posting record temperatures in the upper 80s and low 90s earlier this week. The heat wave broke records across Southern California and at Super Bowl LVI, hosted by the Los Angeles Rams in Inglewood.

The temperature two hours before kickoff was 85 degrees, making 2022 the hottest Super Bowl ever, topping the record of 84 set on Jan. 14, 1973, at the Los Angeles Memorial Coliseum.

Los Angeles International Airport recorded a new high of 89 degrees on Saturday and Camarillo also tied its record at 87 degrees.

The coolest day of this week was predicted to be Tuesday, when high temperatures could be 5 to 10 degrees below average.

Dry conditions with a gradual warming trend were predicted for Wednesday through the end of the week.

At San Diego County beaches, a short-period wind swell was expected to produce periods of elevated surf late Tuesday through Wednesday, mainly on west-facing beaches. Increased risks for rip currents were likely to accompany the surf.

Here are some of the areas that saw record highs over the weekend:

Santa Ana - 91 degrees (tied with 91 degrees in 2015)

San Diego - 91 degrees (86 degrees in 2015)

Vista - 90 degrees (87 degrees in 2015)

Chula Vista - 93 degrees (87 degrees in 2015)

Riverside - 88 degrees (tied with 99 in 2016)

Escondido - 90 degrees (89 in 1971)

El Cajon - (tied with 89 in 1971)

Idyllwild - (tied with 73 in 1957)

Camarillo - 89 degrees (87 degrees in 1971)

UCLA - 89 degrees (88 degrees in 1971)

LAX - 89 degrees (79 in 1917)

Paso Robles - 84 degrees (79 degrees in 1971)
