Tonight, Illinois is experiencing light to moderate concentrations of avian movement. The northern half of the state is experiencing movement more towards the moderate end of the spectrum, whereas the southern half is experiencing lighter concentrations. This can be seen on the current national composite radar, which is showing some rain cells that are most likely disrupting migration in southern Illinois: http://tempest.aos.wisc.edu/radar/us3comp.gif
Hawk watching forecast: If you are in northeast Illinois, GO HAWK WATCHING TOMORROW! Perfect conditions, 10-20 mph northwest winds will be in effect, spurring raptors to migrate and funneling them towards the lakefront sites such as IBSP, Fort Sheridan, and, to a lesser extent, Greene Valley.
