Snowstorm to Graze Chicago Sunday

While the worst of the snowstorm crossing the United States will bypass Chicago, the "Windy City" will not escape a snowy Palm Sunday.

The majority of the heavy snowfall will fall between I-70 and I-80, spanning only a few hundred miles across the Plains. With such a narrow band of heavy snow, areas just outside the band will see substantially lower snow amounts.

Chicago is one of the cities that lies just north of the heavy snow zone with 1 to 3 inches of snow expected to fall Sunday through Sunday night.

The city's southern suburbs have the greatest opportunity to see snow totals on the higher end of that range, while the northern suburbs may struggle to pick up an inch.

When asked about travel impacts in Chicago, AccuWeather.com Meteorologist Bill Deger said, "With temperatures expected to be right around the freezing mark, there certainly can be some impacts on roadways, especially secondary and untreated surfaces later in the day when the snow is expected to be steadier."

"The threat for icy spots will increase [Sunday] evening after sunset with temperatures likely to drop below freezing, even if the snow is tapering off," Deger added.

The combination of the snow and accompanying low-hanging clouds may also cause headaches for airline travelers on Sunday. The ripple effect of delays and cancellations at Chicago's O'Hare International Airport could lead to problems at other airports across the nation.

This winter started off very dismal for Chicago, with only 3.5 inches of snow from November through January. Winter picked up in February, however, when the city received 16 inches of snow, making it the snowiest month of the winter thus far.

So far in the month of March, the city has picked up just over 10 inches of snow. With more snow on the way, March might give February a run for its money as the snowiest month this winter.

It is not uncommon for a late-season snowfall for Chicago where more than 2 inches of snow falls. On average, a snow event for the city with more than 2 inches of snow occurs about every other year; however, the last time that this happened was back in 2008.
