Dramatic weather changes are underway, among them a precipitous temperature drop, likely to produce the Chicago area’s first lake-effect rain showers Friday. The downturn, which is to effectively slash readings from mid-July to early November levels, comes on the heels of the second warmest October since official records began here in 1871.
The month’s opening five days have posted a nearly unprecedented 15.8° temperature surplus. Only October 1-5, 1922 was warmer, averaging 75.6° compared to this year’s 73.4°.
Tropical Storm Tammy’s formation off north Florida Wednesday leaves only two names on the formal 2005 hurricane list: Vince and Wilma. Greek alphabet letters (i.e. “Alpha”, “Beta”, etc.) will be employed to identify any additional storms. Before landfall, Tammy swamped St. Simon’s Island, Ga. with 10.52” of rain.
WGN-TV Chief Meteorologist Tom Skilling and the WGN Weather Center staff provide daily coverage of weather in the Chicago area.
