The lack of snow set a new record this morning, but enjoy it while it lasts: Parts of the Midwest could see heavy snow on Thursday, and Chicago is unlikely to be spared.
A snowless Sunday means 2012 will set a new record for the latest date of first measurable snowfall in Chicago.
The previous record year was 1965 when it took until Dec. 16 for O'Hare International Airport to record at least one-tenth of an inch of snow, the National Weather Service's threshold for measurable snowfall.
This year's snowless streak is likely to end Thursday, when a low-pressure system currently over the eastern Pacific Ocean will reach the Midwest, said Mark Ratzer, a senior meteorologist with the National Weather Service in Romeoville.
Parts of the Midwest could see six to 12 inches of snow, and it remains unclear precisely what path the storm will take, Ratzer said.
Current models suggest the heaviest snowfall will land to the west of Chicago, from northern Missouri through eastern Iowa and up into Wisconsin, Ratzer said.
Depending on the storm's path, Chicago could get several inches or less than an inch, but it appears the city will get at least the tenth of an inch needed to record the season's first measurable snowfall, Ratzer said.
