Oct 13 - 15, 2015
This week is turning out to be very busy for me, so the only other days I will be posting reports will be Thursday and Friday nights. This report, therefore, covers tomorrow (Tuesday), Wednesday, and Thursday.
Tonight, Illinois is experiencing moderate to locally heavy concentrations of migration, especially in the western part of the state, as seen by the blue and green radar noise on the current national composite radar (http://tempest.aos.wisc.edu/radar/us3comp.gif).
Tomorrow night, favorable winds should bring moderate to heavy concentrations of migrants again, and Wednesday night should be fairly productive again in the southern half of the state but much less so in the northern half.
Hawk Watching Forecast: Tomorrow (Tuesday) and Wednesday look extremely favorable for hawk watching conditions with respectively northwest and west winds on both days in northeast Illinois. It would be very worthwhile to get out to Fort Sheridan, IBSP, or other hawk watching locations tomorrow and/or Wednesday to see the raptor spectacle!
In summary, here is what to expect over the next few days:
Tuesday: Favorable for overall turnover as well as hawk watching.
Wednesday: Favorable for overall turnover only in southern half of state, but favorable for hawk watching in the northern half.
Thursday: Favorable for overall turnover in the southern half of the state but unfavorable in the northern half due to rain.
