San Diego County will have “unprecedented mid-March heat” through Tuesday and likely much longer, resulting in record temperatures across the region, according to the National Weather Service.
Records were set locally Thursday — something that’s also expected to happen on Friday as well as Monday and Tuesday.
Chula Vista on Thursday hit 91, one degree higher than the record for March 12, set in 2007. Ramona reached 90, tying the date for the record also set in 2007. Alpine got to 92, three degrees above the 2007 record. And El Cajon reached 94, tying the record set in 2007.
Forecasters say San Diego’s daytime high will hit 86 on Friday, 81 on Saturday, 79 on Sunday, 82 on Monday and 83 on Tuesday. The seasonal high is 67.
“There will be a little cooling on Sunday, but overall temperatures will be above normal everywhere through Tuesday and maybe into next weekend,” according to Kyle Wheeler, a weather service forecaster.
A massive high-pressure system is limiting cool, onshore winds from reaching the coast.
