MILWAUKEE — An unusually mild winter finally gave way to the Midwest’s first big snowstorm of the season Thursday, blanketing a region unfazed by a white Thanksgiving in a layer of powder and pack that forced all-too-happy snowplow drivers off their couches and into the streets.
The storm dumped several inches of snow on western parts of Wisconsin and Iowa before moving eastward into Milwaukee, St. Louis and Chicago, where up to eight inches were expected to fall by Friday morning.
In a typical year, such a storm would hardly register in the upper Midwest. But the atmospheric patterns, including the Pacific pattern known as La Nina, that have conspired to make this an unusually icy winter in Alaska have kept it abnormally warm in parts of the lower 48 states used to more snow.
The storm dumped 2 to 6 inches of snow on eastern Iowa by Thursday evening, and was expected to drop 3 to 8 inches total on southern Wisconsin and northern Illinois as it moves further into the Northeast on Friday, according to Richard Castro, a National Weather Service meteorologist.
While the dry weather has been an unexpected boon to many cash-strapped communities, which have saved big by not having to pay for plowing, salting and sanding their streets, it has hurt the seasonable businesses that bank on the snow.
The storm was an annoyance for most commuters, and authorities said it caused hundreds of traffic accidents and at least three road deaths — two in Iowa and one in Missouri. And while some lucky grade-schoolers cheered an unexpected day of sledding, hundreds of would-be air travelers had to scramble to come up with a Plan B.
More than 400 flights were canceled at O’Hare International Airport on Thursday and flights that did depart were delayed 20 minutes, on average, because of deicing, the Chicago Department of Aviation said. Across town at Midway International Airport, more than 100 flights were canceled, although Southwest Airlines said it planned to resume its flights Thursday evening.
In New York state, the storm dumped up to 8 inches of snow on the southern Adirondacks and forced scores of schools to cancel or delay the start of classes. The weather service said until Thursday’s storm, Albany had received only 6.5 inches of snow this winter, which is about 10 inches less than it normally gets.
