Yep, it did get unusually cold in San Diego County overnight. Blame it on the low pressure system that produced Monday’s big wind storm.
The National Weather Service says that cold air from the system sank to the ground after the winds fully faded away on Tuesday.
At 7 a.m. on Wednesday, San Diego International Airport was only 52 degrees, 10 degrees below average for this time of year. Carlsbad Airport was 51, nine degrees below average. Oceanside Harbor was 45, also about nine degrees below average.
“Last night got about as cold as it gets here this time of year,” said Phil Gonsalves, a weather service forecaster.
Don’t worry; this is a fleeting thing. The region’s weather will begin to warm up on Wednesday and overnight averages will quickly return to normal.
