Assignment: Predict the snow depth at the end of the day (inches) for Minneapolis-St Paul, MN (KMSP)
The Minnesota Twins have a home game scheduled at Target Field (open air stadium) for Friday night against the Tigers. But since there are 6 inches of snow already on the ground on Thursday morning, a current Winter Storm Warning and more snow expected Friday, it's difficult to imagine a game being played on Friday. So let's forecast the snow on the ground at the end of the day Friday and see what happens.
