Tonight, due to the aforementioned storm systems and precipitation, we're not seeing as much movement as we could. Storms break up what would be the even distribution of migration throughout this third of the state, so areas host to storm activity during peak migration time (somewhere between 11ish and 3ish) will probably not see as much influx tomorrow. Looking at the radar (NW IL, NE IL), birds definitely are still moving where they can in light to moderate concentrations (between 50 and 200 individual birds moving per cubic kilometer of the sky). They're nervous, but they're still moving. Looking ahead at the wind forecast, it appears that tonight's favorable conditions will be short-

This one's going to be a little shorter because Central Illinois is basically in the same boat tonight as Northern Illinois. Precipitations is moving through Central IL tonight, but is much less concentrated. For that reason, migrants are still a little nervous, but influxes should be more evenly distributed around the region tomorrow morning. Looking at the radar, migration is light to moderate tonight, and is certainly a bit heavier than the average migration in Northern Illinois. As in Northern Illinois, however, tonight's favorable conditions will be short-lived. Expect westerly and then northerly winds developing tomorrow thanks to the passage of a cold front from the North. So like in Northern Illinois, bird it up tomorrow!
This third of the state is experiencing the best conditions right now, with more powerful, uninterrupted southerly flow. This means that migrants are a-flyin', and the radar (SW IL, South-central IL, SE IL) doesn't lie. I'm tempted to call the movement there almost heavy, but it's on the upper end of moderate. With that, migration appears to be evenly distributed with the lack of precipitation, so tomorrow influxes of warblers, thrushes, vireos, sparrows, waterbirds, etc. should be readily visible throughout the
