Huge crowds of spectators gathered along the lakefront for the Air and Water Show on Saturday.
The annual weekend show, which starts up again at 10 a.m. on Sunday, features the U.S. Navy Blue Angels, who perform aerial tricks in their F/A-18 Hornets.
A clear blue sky welcomed the show on Saturday, with the National Weather Service forecasting a high of 74 degrees.
But city officials warned that Sunday's showgoers might not be as lucky. The National Weather Service's Chicago office said there would be a 40 percent chance of rain on Sunday after 1 p.m.
The head city's Office of Emergency Management and Communications said Sunday's observers should be prepared for the possibility of rain.
"As millions of people gather along Chicago's lakefront to enjoy the festivities this weekend, it is important that they stay aware of their surroundings and prepare for any possible change in weather conditions," said OEMC Executive Director Gary W. Schenkel. "As it does for every large-scale event, our operations center will work closely monitor the festival to ensure the safety of the public."
A spokesman for the Chicago Police Department said no traffic accidents or other incidents related to the Air and Water Show had been reported Saturday morning.
The Chicago Transit Authority will increase service on various train lines during the two-day event.
Trains running on the Blue, Brown, Red and Orange lines will include more cars before and after the annual show and more buses will be deployed along the lakefront.
The CTA said it urges commuters to leave early and allow for extra travel time.
