I thought it was a large firework at 1st. Was driving Southbound down the Interstate in the middle of well lit city. Meteor was very bright. Notable light green color with some other colors as it ended with a somewhat white flash. Had a notable short illuminated tail as it fell. Seemed to come from overhead and head SW, but reports I saw say it was over southern WI heading east of North. Hard to explain its trajectory. I was facing SSW and saw it about 45 Deg up and about 20 deg to my right. So basically high in the SW sky. Seemed to be falling to the SW but was done at maybe 25 deg elevation.
