Heaviest rain to skirt city to the south

A year ago as the city was emerging from a prolonged drought Chicagoans would be lamenting about missing out on another rain event, but this year after a soggy late summer and autumn it is a welcome relief. With the center of low pressure forecast to pass south through the Ohio Valley, the city expects only light rain while heavier amounts up to two inches soak downstate.
Wednesday morning’s frosty 27º low at O’Hare was the coldest of Autumn 2006 to date, and the coldest temperature to occur this early in the season in 10 years. In 2005, a reading that low did not occur until Nov. 16 when the mercury dipped to 21º. A seasonably cool weekend should follow in the wake of the storm, but it is beginning to look like the city is in store for an early Halloween treat on Monday as readings are expected to surge into the middle 60s, the warmest weather here in three weeks since a 66º on Oct. 9.
