As predicted, tonight has brought powerful southerly winds over Illinois. Perhaps even more significant, precipitation has entered the Prairie State in a variety of places. A combination of these factors has allowed only light to moderate concentrations overhead, with nothing moving where it's raining. As storms systems pass over Illinois tonight, they will block any migration they encounter. Luckily, most of the storm systems on the radar right now are limited in size, so some influxes should be apparent tomorrow regardless of where you are.

As migration continues to wind down in the next few days, let's look at how the winds will affect them. Tomorrow night, winds are forecast to remain favorably southerly, so migration should again be visible Tuesday morning. On Tuesday, a front from the north is set to enter Northern Illinois, bringing unfavorably northerlies with it. By Wednesday night, these winds are forecast to block off the northern half of the state, restricting any migratory remnants to Southern Illinois. But fear not! Winds are then forecast to become southerly again by Thursday night.

Good stuff, Illinois. Predict which migrants are still out there using this eBird Page for an Illinois focus, or the latest BirdCast National Migration Forecast for a regional focus .

As always, thanks for the read, and good birding!
