The Effects of a Storm Front

Here's a really interesting radar map from Tuesday night at 11:30 pm CST. Look at the heavy movement of birds to the east and south of the storm front moving east out of the Mississippi River Valley. The flight appears to be pretty significant ahead of the front and nothing is moving behind the front.

Here in Minnesota we've had a day of pretty intense snow and wind especially in the western part of the state. The temperatures are plummeting and we'll be very cold the next couple of days. South of here the front was a line of strong rain storms but it looks like the migrants are trying to move ahead of the storms.

You don't get a better map to compare areas of movement with areas where everything is staying where they are.

Is there a similar mapping system that shows the western half of the country?
