Chicagoans flirt with record cold later this week

The Chicago Tribune reports:

Columbus Day will be cooler than this past weekend, but nothing like the cold expected later this week. Today's slightly below-normal highs will probably be the warmest readings Chicagoans will experience until perhaps the middle of next week. The upper-air pattern is forecast to change drastically in the next 36 hours.

Presently, winds at 30,000 feet over Chicago are southwest around 40 m.p.h. with the 100 m.p.h.-plus core of the jet stream situated along the U.S./Canada border. By Wednesday, the jet stream flow will shift north-south with a core of 150 m.p.h.-plus winds just to the west through the Dakotas and western Iowa. An Arctic-source high pressure air mass will be steered directly south through Canada into the western Great Lakes and Midwest. By Thursday, there's a good chance snow will blanket northern Wisconsin and upper Michigan, while the Chicago area is hit with record cold (highs in the 30s Thursday) and snow flurries.

No word yet from Al Gore on this one.I guess the belief in global warming is a religion to some.
