Well it looks like the first big movement of migrants is starting. The picture of Nexrad radar taken about 10:20 pm shows lots of classic green donuts concentrated mostly in the southern U.S. east of central Texas and south of the Ohio River Valley. Big flocks of Red-winged Blackbirds and waterfowl perhaps???
There is a bit of storm activity near the Gulf Coast that probably masks any movement in that area. With strong winds from the south predicted for the midwest tomorrow (at least they are here in Minnesota) we should see more movement tomorrow night.
It's only going to get better from here!
