The average wind direction for Detroit for November from 1930-1996 was WSW at 11 knots according to the pdf attached. It surprised me as well. I even thought that it might be the direction the wind came from (as winds are often reported) but the pdf does seem to support it is the direction.
I may throw in some Canadian weather station reports, for greater accuracy, if I can dig them up.
