Oct 20 - 24, 2015
This is a report covering tonight all the way to this Saturday, the 24th. Tonight, Illinois is experiencing absolutely no migration - as evidenced by the complete lack of radar noise over the state on the current national composite radar, seen here: http://tempest.aos.wisc.edu/radar/us3comp.gif
After consulting the Weather Channel for wind forecasts, here is what this week should look like in terms of arrivals and influxes into the state:
Tonight: Almost no movement
Tomorrow (Tuesday) night: No movement expected in northern part of state, possible light concentrations in southern Illinois
Wednesday night: Moderate to heavy concentrations in northern part of state, negligible to light movement in the south
Thursday night: Moderate to heavy concentrations in northern part of state, negligible to light movement in the south
Friday night: Due to statewide rain, very little migration should be expected, if any at all.
Hawk Watching Forecast: Note, this is for northeast Illinois because Greene Valley, Fort Sheridan, and IBSP Hawk Watches are located there.
Tuesday: Light to moderate movement possible, partly cloudy skies
Wednesday: Light to moderate movement possible, partly cloudy skies
Thursday: Light movement possible, partly cloudy skies
Friday: Negligible movement, mostly cloudy skies.
Saturday: Light to moderate movement possible in the afternoon with mostly cloudy skies.
To predict exactly which species you are likely to find and when, please consult:
BirdCast's regional migration forecast for this week: http://birdcast.info/forecast/regional-migration-forecast-16-23-october-2015/#MidwestNortheast
In summary, the best days to look for newly arrived species this week should be Thursday & Friday and although hawk watching isn't forecast to be overly remarkable in northeast Illinois this week, your best chances at seeing some raptor movement would be tomorrow (Tuesday), Wednesday, or Saturday afternoon.
