Temperatures surged above 80 degrees a fourth consecutive day Tuesday, and
Wednesday's predicted 80-degree high may extend the streak to five. The late-season
warm spell is occurring despite the seasonal challenges of shorter days and weaker
sunlight. The warmth caps a month of volatile temperature swings that have produced
an average September 2008 temperature of 66.7 degrees -- equal the 137 year
long-term average, yet 2.5-degrees cooler than a year ago. Not only did the mercury hit
90 degrees on this date last year, Chicagoans enjoyed 10 additional 80-degree or
warmer days before the chill of fall and winter took hold.
Chicago isn't alone in enjoying the warmth. LaCrosse, Wis., recorded its eighth
consecutive 80-degree day Tuesdayaa -- the longest late-season string in 100 years
there.
SPRAWLING ATLANTIC STORM COULD INCLUDE TROPICAL STORM KYLE
With tropical forecasters fearful forma- tion of 2008's 11th tropical storm could occur
at any time, it's worth remembering two tropical storms (Jerry and Melissa) and two
hurricanes (Karen and Lorenzo) developed this week a year ago. Powerful winds and
10-12 foot waves pounded the area from Florida to New England Tuesday.
