After temperatures across Southern California hit the mid-90s on Wednesday, cooldown and possible showers are expected in parts of the region this weekend.
It was a hot Wednesday, with temperatures up to 94 degrees at Los Angeles International Airport, but the mercury could drop as low as 30 degrees in some areas.
“We’re in our fall season, so expect big swings in the weather,” said Ryan Kitell, meteorologist with the National Weather Service in Oxnard.
After an offshore current helped make Wednesday the hottest day of the week, Kitell said there were already signs of cooling on Thursday.
At LAX, the day was sunny and warm, with temperatures in the mid-80s and a high of 86 degrees before a partly cloudy evening.
Sunny skies are expected to give way to a rapid drop in temperature, with patchy fog expected Friday morning, overcast skies throughout the day and perhaps some drizzle late Friday evening, according to the National Weather Service.
Through Friday, most areas in Southern California can expect the day to linger in the mid-70s and 80s, Kitell said.
An onshore river is expected to lower temperatures across the region, especially along the coasts.
By Saturday, the high at LAX will peak at 69 degrees and there is a 10% to 20% chance of rain during the day and night.
In Anaheim, the maximum temperature on Thursday was 93 degrees. Temperatures are expected to drop to 81 by Friday and 70 by Saturday, with a 30% chance of rain overnight.
A deep layer of ocean is expected to lie over southern California, Kitell said, bringing breezy onshore winds and some drizzle. The low-pressure system will bring cool temperatures and some rain from Ventura County to San Diego County, he said, but full showers could be seen in some locations over the weekend.
In Riverside, the temperature is expected to drop to 72 degrees by Saturday, with a 40% chance of showers.
People should expect warmer conditions through Monday, Kitell said. Moderate Santa Ana winds are expected to return after the weekend, bringing temperatures into the 70s and lower 80s.
