EDGEWATER — The rainy summer season and first full week of fall collided on Lake Michigan on Wednesday morning in the form of a waterspout, visible everywhere from the South Loop to Edgewater.
YouTube user Randall Stieghorst posted a video online showing the weather phenomenon as seen from the Far North Side around 8:30 a.m. Wednesday.
On Twitter, user Ima Bedhog posted a video of the same spout, but near the Adler Planentarium.

The National Weather Service said on social media weather conditions made it so waterspouts were "likely to form" throughout the day and night, particularly around the southern end of Lake Michigan near Indiana and Chicago — even warning at one point the spouts could move on land.
Multiple other spouts were reported, according to the weather agency.
Generally, waterspouts form when cold and warm winds from different areas converge begin a low-velocity spin that eventually becomes unstable, forming "lake effect" rain storms.
As that force moves, it can stretch upward, creating waterspouts. The National Weather Service said they often form in "families" of multiple spouts.
