A year ago, Chicago was in the midst of an unseasonably cool four-day late-season stretch of daytime 60s. This year couldn’t be more different. For the 22nd time this year (versus last year’s 13), Chicago’s official temperature is to top out well above 80° Tuesday on a second consecutive day with 100% of its possible sunshine. That means 2007 is maintaining a pace of 80°+ high temperature production 62% ahead of a year ago. It’s a trend which has historically segued into summers which have averaged 31 days at or above 90° instead of the 21 considered normal.
June 2007’s 68.1° temp is running more than 2° above the long term (137 year) average and 3.0° warmer than a year ago. Only immediate lakeshore areas are unlikely to hit or exceed 80° Tuesday thanks to easterly winds off chilly lake waters.
