Temperatures surge back to 90° briefly Wednesday afternoon. But, there are few signs Chicago is in for extended heat in the foreseeable future—the kind that takes up residence for days at a time. That’s no guarantee hot weather will continue a no-show here as Summer 2006 matures. Chicagoans who like their weather truly hot and laced with humidity may be comforted to learn that in 20 years with a 90° count by June 20 comparable to this year’s four at Midway Airport, an average of 26 readings in the 90s ended up occurring in 13 (or 65%) of those years. It’s a number which exceeds the 30-year average of 21.
Delightful weather dominates Tuesday. A “bubble” of high pressure is in control prompting east winds off the lake. June’s average temperature to date has been 68.0°—3.4° cooler than a a year ago. In 135 years of official weather records dating back to 1871, 50 June 1-20 periods have been warmer and 85 cooler.
