Chicagoan here. When I rode my bike 40 years ago it was a perpetual west/southwest wind in the Spring. Warm air blowing in from the southwest. Aided many a home run out of Wrigley Field too, where 20 run games were almost common in April and May. Now it seems like a perpetual northeast wind blowing in off Lake Michigan until mid June. The other day we had a southeast wind! Air temp close to 60 degrees and going into the SE wind got you darn cold. Thats just weird.
