Interesting report tonight. Thanks to a large high pressure system centered over Michigan, winds in Illinois are east-northeasterly. At most times of years, these winds would prohibit heavier concentrations of migration, but not tonight. While migration is not consistently heavy across the state, moderate to heavy movements are occurring over some of Southern Illinois, as well as a small patch in northeastern Illinois. Elsewhere, movements overhead are light to moderate and spotty. Overall, we will see some arrivals and influxes tomorrow. Their magnitude will depend merely on where you are.

Looking ahead at the wind forecast, southerly winds remain predicted for tomorrow (Thursday) night. As before, these winds are set to be very strong, so we'll see how heavy migration actually gets. From there, winds are forecast to remain southerly based at least through Sunday. From there, favorable conditions may deteriorate for a short while. I'll keep you posted.

Until then, what might you find out there tomorrow? Answer for yourself using this eBird Page or the latest BirdCast National Forecast.

Good stuff, folks. Best of luck to all those birding tomorrow.
