Chicago has had the longest streak of above-normal daily temperatures in any November since records have been kept:
The last day of November will see Chicago's 27th record-setting consecutive day with above-normal temperatures. Warmer readings are likely Tuesday as southwesterly winds and abundant sunshine allow afternoon high temperatures to approach and even exceed 50 degrees at many observation points around the metro area. A cold front should pass through Chicago early Wednesday, followed by a sudden turn to colder weather with falling temperatures.
In practice, this means that November felt like October, which, because of the 20 days of below-normal temperatures that month, felt like November. The forecast calls for a normal December, and who-knows-what in 2010.
Tomorrow we look forward to the correction: after the day's high of 11°C at midnight, a slow slide to -2°C before the snow pushes in on Wednesday. Yummy.
