MLB’s central weather monitoring team first issued a pre-game delay alert approximately 80 minutes before the scheduled 7:10 p.m. first pitch, after radar data showed heavy rain, wind gusts up to 62 miles per hour, and frequent cloud-to-ground lightning strikes heading directly toward the Lakeview neighborhood where Wrigley Field is located. Wrigley Field staff immediately began implementing league-mandated rain delay protocols, directing fans already in the stadium to move to covered concourses and lower-level seating areas to avoid exposure to the elements. Concession stands and official team merchandise stores remained fully operational during the delay, with stadium staff also distributing free bottled water and disposable rain ponchos to fans waiting out the storm. In a statement posted to the Cubs’ official X (formerly Twitter) account, team representatives noted that they would provide public updates every 30 minutes regarding the potential adjusted start time, adding that no decision to postpone the game entirely would be made until at least 9:15 p.m. to give meteorologists time to assess the full path of the fast-moving storm system. Many fans who had traveled to the stadium from across the Midwest shared real-time updates of the storm on social media, with some posting photos of lightning strikes visible directly behind the iconic Wrigley Field scoreboard. For season ticket holders, this delay marks the third weather-related disruption to a Cubs home game during the 2024 regular season, following two partial rain delays in April and early May. MLB rules state that games delayed by weather must be resumed if at least five innings have been completed, or rescheduled for a doubleheader on a subsequent date if the delay stretches beyond three hours and no clearing window is visible in the local forecast. As of 7:50 p.m. local time, meteorologists tracking the system reported that the worst of the thunderstorms was expected to pass the Wrigley Field area by 8:30 p.m., with clear, cool conditions forecast for the remainder of the evening. Cubs officials added that fans who are unable to attend the game once it starts would be eligible for partial ticket refunds or credit towards any future home game during the 2024 or 2025 regular seasons.
