A very interesting radar tonight (11 pm). It shows a concentration developing along a cold front (shown on the regular weather map) through southern Ohio and central Indiana where the wind shifts from a southerly direction to a northerly one. I think this site shows the current conditions when you access it. http://lnk.nu/rap.ucar.edu/eja.php To get conditions for any time tonight go to http://www.rap.ucar.edu/weather/radar/ and enter 0300 (for the time I have right now - 11 pm) or later, to see what is happening then. You can see the effect by clicking on "Contiguous US" but it is striking if you check "Regional reflectivity" at the left and ILN in Ohio. You can set the time in motion be setting the loop duration to the number of hours you want. If this front happens to push back north, it should have lots of birds behind it. however, the prediction is not until Tuesday. I don't know what the bird psychology is at this time in May, but perhaps they might gradually push onward.
