This will be a combined forecast for tomorrow (Tuesday, Sept 29) through Thursday (Oct 1) mornings since I have choir tomorrow and Wednesday evenings.
Tonight, Illinois is experiencing widespread MODERATE migration as evidenced by fairly uniform blue radar noise across the state on the current national composite radar (http://tempest.aos.wisc.edu/radar/us3comp.gif). Please note that the much more scattered and green and yellow markings are rain showers as part of the weather systems that are currently sweeping across the midwest. So, tomorrow morning should be a good morning to get out...if it is not raining in your part of the state, that is.
Northerly winds with less rain both tomorrow and Wednesday nights should mean that some nice turnover, arrivals, and influxes should be evident Wednesday and Thursday mornings. Pretty soon I bet those Hermits will start replacing Swainson's Thrush in northern Illinois - get ready!
To predict exactly which species you are likely to find and when, please consult:

In summary, birding should be fairly productive across the state tomorrow (Tuesday) morning, but even more so on Wednesday and Thursday mornings!
Good birding,
Henry (Oak Park, Cook County)
