The high in Minneapolis, MN is going to be 24F on Sat, 27F on Sun and 21F on Monday! I cannot even IMAGINE how cold that will be, especially if you factor in the wind chill factor. I hope my clothes are warm enough - I just didn't want to go buy some winter clothes for 2 days in the cold.
On the up side, I think it will be fun to see some snow (only for a couple days though - Houston doesn't have the greatest weather but I like the mild winters!).
