Tonight, the northern two thirds are receiving almost no migration while the southern third of Illinois has increasing migration levels up to some moderate movement over the far southern tip. This can all be seen on the national composite radar: http://tempest.aos.wisc.edu/radar/us3comp.gif
Hawk Watching Forecast: Tomorrow should bring southerly headwinds to the entire state, meaning negligible raptor movements. Also, tomorrow night will have very little movement due to southerly winds forecast to remain in the state.
To predict exactly which species you are likely to encounter and when, please consult:

In summary, tomorrow (Sunday) and Monday mornings look like they will play host to very little, if any, avian turnover in most of the state.
Good birding,
