Fans at Wrigley Field on Monday night saw something that is rarely seen in Chicago and no, sorry, it’s still not a World Series game. During the Cubs 4-2 victory over the Dodgers, one that pushed their mini winning streak to three games and put them eight games above .500, the crowd was also treated to an incredible sight in the sky.

Check out these insane clouds that hovered over the historic ballpark during a portion of the game. According to AccuWeather, they’re mammatus clouds:
