Taking a look at the Duluth and Minneapolis NEXRADS from the past couple of hours, I'm noticing a huge exodus and departure, moving from the SE and heading NW, especially over Duluth.
I'd been keeping an eye on things the past couple of nights and nocturnal migration had been quite sluggish, possibly slowed due to wind directions, temperatures, and rain. But, tonight I think the bottle-neck finally cleared and the birds are really flowing. Here's a couple of great links on watching migration via RADAR: http://virtual.clemson.edu/groups/birdrad/index.htm http://my.execpc.com/CE/5F/idzikoj/nexrad/nexweb/nexrad.htm Also, here's my favorite source for NEXRAD: http://www.rap.ucar.edu/weather/radar/ Just a clue. 01:00 UTC is 7:00 PM CST, so you can work backwards from there. Tonight though, as RADAR becomes available every 15 minutes, you can set the End Time to be "Most Recent" and then choose a block of hourse as the "Loop Duration" for "Today" and it'll give you tonight's RADAR when you click on the station.
