One of Chicago’s most famous summer traditions, the Chicago Air and Water Show, returns to the Lake Michigan shoreline this weekend, bringing some of the best-known U.S. military and civilian aerial performers to the city.
The show is scheduled for Saturday and Sunday, August 15 and 16, from 10:30 a.m. to 3 p.m., with North Avenue Beach serving as the main viewing area and the event extending along the lakefront from Fullerton Avenue to Oak Street.
This year, however, spectators may be watching the weather as closely as the aircraft. The forecast includes additional thunderstorms, heavy downpours and the possibility of strong wind gusts. FOX 32 expects mostly cloudy conditions with storms Saturday, with more storms possible Sunday. 
Thunderbirds and Golden Knights Headline the Show
The U.S. Air Force Thunderbirds and the U.S. Army Parachute Team Golden Knights are the headliners of this year’s Chicago Air and Water Show.
The military lineup also includes the U.S. Air Force C-17 Demo – 15th Airlift Squadron, the Illinois Air National Guard KC-135 – 126th Air Refueling Wing, a U.S. Coast Guard Search & Rescue demonstration, the F-22 Raptor Demonstration Team, the USMC F-35B Lightning II Demonstration Team, and four F-16s.
Civilian performers include Coleman Aerosports – Kevin Coleman, Super Stearman “Big Red” – Susan Dacy, Folds of Honor Biplane – Ed Hamill, and the Trojan Phlyers Flight Demonstration Team.
Chicago Police Department helicopters and the Chicago Fire Department Air / Sea Rescue team are also scheduled to participate.
One familiar team will be absent. The U.S. Navy Blue Angels are not performing in Chicago this year, with the team scheduled to appear at the Oregon International Air Show in McMinnville during the same weekend.
Saturday Morning Could Face the Biggest Weather Problems
The greatest weather uncertainty appears to be concentrated around Saturday morning and the opening hours of the show.
ABC7 reports that much of the Chicago area is under a Level 1 out of 5 severe-weather risk, with damaging wind gusts among the main concerns. The main line of storms is expected to reach western portions of the Chicago area between approximately 4 and 6 a.m. before moving quickly east.
Rain is expected to gradually end between noon and 2 p.m., although pockets of heavy rainfall could cause isolated flooding. A Flood Warning for Cook County rivers remains in effect until 1 p.m. Saturday.
FOX 32 also forecasts a mostly cloudy Saturday with storms and temperatures in the low 80s.
Because the show begins at 10:30 a.m., the forecast suggests that the opening portion of Saturday’s program could be the most vulnerable to delays, schedule changes or canceled individual performances.
Bad Weather Does Not Automatically Mean the Entire Show Is Canceled
There has been no announcement that the Chicago Air and Water Show itself is canceled.
According to the NBC Chicago report provided for this article, Chicago’s Office of Emergency Management and Communications plans to monitor weather and weekend events from its Operations Center and coordinate public-safety resources when necessary.
An air show, however, is far more weather-sensitive than a typical outdoor event. Cloud ceilings, visibility, wind conditions and nearby thunderstorms can determine whether an aircraft or parachute team is cleared to perform.
That means the event could remain open while individual performances are delayed, shortened, modified or canceled.
The Golden Knights’ parachute demonstrations are particularly dependent on suitable altitude and cloud conditions. Performances by the Thunderbirds, F-22 Raptor and other military aircraft also require minimum visibility and safety conditions.
Information included in the NBC Chicago report indicates that organizers have some scheduling flexibility, meaning the show could potentially continue beyond its originally planned end time if weather causes delays.
Sunday Offers Another Chance, but Storms Are Still Possible
Sunday could provide another opportunity for spectators if Saturday’s schedule is significantly disrupted, but the second day is not free from weather concerns.
FOX 32 expects partly sunny skies Sunday, but additional storms remain possible, with temperatures reaching the mid-80s.
ABC7 also reports a chance of storms Sunday.
The timing will therefore be critical. If thunderstorms develop outside the scheduled 10:30 a.m. to 3 p.m. window, much of the program could still proceed as planned. If storms develop over the lakefront during show hours, individual performances could again face delays or cancellations.
What Visitors Should Know Before Heading to the Lakefront
Anyone planning to attend should check the latest radar, weather alerts and city announcements immediately before heading to North Avenue Beach.
A morning forecast alone may not be enough. Air show schedules can change during the day, and individual performances may depend on weather conditions immediately before takeoff.
If the weather cooperates, spectators will see a packed lineup featuring the Thunderbirds, Golden Knights, F-22 Raptor, F-35B and numerous civilian aerobatic performers.
This weekend, the biggest question may not be who is scheduled to fly over Chicago, but how much of the show the weather will allow spectators to see.
