We are planning a backyard wedding either September 22, October 13 or October 20th and am looking to find out the weather for these dates to see which would be best. Any help? :) Thank you!


I am trying to get a feel for this winter for family functions/engagement pictures. I know snow in Illinois hasn’t been as much as previous years recently. Can we expect a decent amount of snow December -January this season?
