The cold front is located at the warm edge of the advancing cold air in a cyclone. As the front passes through Madison, therefore, the temperature will decrease. Since the flow around the cyclone in Madison is counterclockwise (since Madison is in the Northern Hemisphere), winds from the southwest tend to characterize the "warm sector" (the area between the cold and warm fronts) with northwesterly winds howling in the cold air to the west of the cold front. Thus, the correct answer here is (c).
