First, if they don't extend southward from a cyclone center, they probably don't represent a cold front. Second, it's difficult to locate the position of the surface cold front from the position of the band of high clouds. As a general rule, the cold front is near the leading edge of the cloud band to the south, and near the trailing edge of the cloud band near the low center. Take a close look at the infrared satellite image of the Great Lakes region. A broad band of high clouds spirals out from the province of Ontario and across the eastern Great Lakes.
Lower clouds are also visible in the image.
By the above rule, it ought to be somewhere in Michigan, perhaps passing near Sault Ste. But the exact position is impossible to determine from this image. Here's the surface map for the same time. The front turns out to be easily located by the wind shift and the falling temperatures behind the front. The front is roughly parallel to the clouds, but not really, and you can see that you wouldn't want to use a cold frontal cloud band to locate the front if you really needed to know exactly where it was.
