Early Migration

I was just checking radar to see if the predicted snow for Minnesota tomorrow was anywhere nearby when I saw some early migration movement in the southern U.S.

The fun thing to see is how the line of weather along a cold front  moving through Missouri, Illinois and Indiana has shut down any migration to the north. Each of the fuzzy circles with the dark centers are migrant birds. No circles above the front line. I guess we'll have to wait a bit longer for our Red-winged Blackbirds.
