DETROIT -

Friday morning will be chilly, but sunshine will reign over Detroit and Southeast Michigan for students and commuters. People will be able to see their breath with temps starting in the low 40s and upper 30s.

Friday afternoon will be mostly sunny and cool with highs in the low 60s.  Motorists driving westward will need their sunglasses.

After the sun sets, skies thicken with clouds once more with the approach of another cold front. That front will bring rain for the first half of the weekend. Overnight lows will be in the upper 40s.

Saturday will be mostly cloudy and wet with rain moving in for the morning and afternoon. Michigan and Michigan State are at home for college football. The Wolverines take on the Indiana Hoosiers, and the Spartans play host to the Purdue Boilermakers. Fans will need extra gear to stay warm and dry. Afternoon temps will be in the low 50s.

Sunday will be just as chilly for the Detroit Free Press Marathon, the largest international running event in the world. Runners will be comfortable once they get a move-on with temps near 40 degrees. Spectators and volunteers will need to stay warm. Skies will be partly sunny, and daytime temps will be near 50 degrees.

More autumn-like conditions persist next week with sunshine Monday and rain returning later. Lows will eventually reach the 30s and highs stay in the 50s.
