The fog and low ceiling of clouds will probably cause flight delays at the San Francisco International Airport this morning that linger through the afternoon.
A ground delay that limits the number of planes that can land has been issued by the Federal Aviation Administration and will probably start holding up flights around 10 a.m., said airport Duty Manager John Ginty.
Flights in and out of Chicago will probably be the most affected, he said, but overall delays could take up to an hour.
The foggy mornings will probably stick around until Thursday, according to the National Weather Service.
They will probably burn off later this afternoon, but remain pretty consistent with a slight chance of showers Thursday night while temperatures stick to the 60s, said meteorologist Diane Henderson.
Then Friday through Monday expect more sunshine, but still some cooler temperatures, Henderson said.
It won’t be too windy, either, with gusts up to about 10 mph.
