Checking the weather radar tonight I see that migration is pretty heavy in Texas, Oklahoma and Louisiana even with a line of storms just to the north of Oklahoma. Here's what the image looks like:
A comparison of this image to the current wind patterns shown on a national wind map might explain why so much more movement in Texas than in Florida, Georgia, etc. Check this out:
Notice the strong winds moving up through Texas but also how very calm it is in the southeastern U.S.. This is a really good illustration of how favorable winds help move birds along on their long journey. When trying to predict where the heavy movement will occur, looking at the wind map may be another way to anticipate hot spots. The animated wind map can be found at: hint.fm/wind/
