Wait a minute, didn't spring start last week?
Folks in more than a dozen states, from Missouri to New Jersey and down to North Carolina and Tennessee, navigated dogged precipitation to get to work or school Monday morning.
As of 2 p.m. Monday, the National Weather Service had placed a dozen states under winter weather advisories, and most of those states were also subject to the more severe winter storm warnings.
Accumulations of up to 7 inches were expected in places such as St. Louis, Indianapolis and Pittsburgh. Forecasters predicted some areas would receive a foot of snow.
Mix in blustery winds, and it's a bit of a mess.
Time to break out the sleds
More than a foot of snow blanketed St. Louis on Sunday, making it the snowiest single March day ever in the Gateway City, and the second-snowiest day, no matter the month, dating back to 1892.
"I'm a little bummed out," St. Louis resident Mary Kelly said at the prospect of another snow day. "It's a little bit of a buzzkill."
Her son was excited though, getting a day off from school, with spring break scheduled to start Thursday.
"We'll break out the sleds again," she said. "We've got some pretty good sledding hills around here."
Still, the irony isn't lost on Kelly, who knows how changeable Midwestern weather can be.
"The good news is: It's St. Louis," she said. "Next weekend, it could be 80 degrees."
The snow prompted flight cancellations and delays across the Midwest and mid-Atlantic states.
Around 2 p.m. Monday, FlightAware.com said nearly 600 flights "within, into or out of the United States" had been canceled, after 415 cancellations were tallied nationwide Sunday.
The website said flights in and out of the three largest New York-New Jersey Port Authority airports -- Newark, John F. Kennedy and LaGuardia -- made up more than a quarter of those cancellations.
And even when flights weren't canceled, the storms wrought havoc on travel plans, with delays of at least an hour and a half at the Philadelphia, Newark and JFK-New York airports, and 30- to 45-minute delays at the three largest Washington, D.C., area airports.
In Indianapolis, Mayor Greg Ballard told nonessential city employees that they didn't have to come into work until 1 p.m. because of the storm, affiliate WISH-TV reported. Dozens of school districts called off classes for the day.
In several places, snow was accumulating in historic amounts.
Springfield, Illinois, witnessed an all-time single-day record of 17 inches Sunday, in a city where records go back to 1881.
In Pittsburgh, forecasters were talking about the rare, heavy spring snowfall. Up to 8 inches are expected.
"From a historical perspective, we've only had snow on the ground, this date or later, of 6 inches or more four times," Michael Fries with the National Weather Service told affiliate KDKA-TV.
The last time was in 1987, when 7.7 inches fell, setting the record for an early spring storm.
