Another snowstorm threatened the Monday commute in the Mid-Atlantic, with several inches of snow expected from St. Louis to Philadelphia, forecasters said.
Rain late Sunday from the south will meet cold air from the Great Lakes and turn to snow and sleet in St. Louis, Louisville and Cincinnati, according to Accuweather.com. Virginia and Maryland should get a few inches, with up to a half-foot in the mountains, Accuweather says.
Driving conditions on slick streets are expected to be poor in Charleston, W.Va., Washington, D.C., and Baltimore. A few flakes could reach the St. Patrick's Day Parade in New York City.
"It's the typical roller-coaster ride of March," AccuWeather.com senior meteorologist Dave Dombek said, after warmer weekend weather. "March is notorious for huge temperature swings."
By 1 p.m. ET Sunday, the flight-tracking service FlightAware.com found only 162 domestic cancellations.
The storm comes just days before spring officially arrives on Thursday, and adds insult to injury at Northampton Community College in Bethlehem, Pa. The school, which has about 10,000 students, canceled spring break, which was supposed to start Monday, after missing about a week's worth of classes earlier in the school year because of storms, said spokeswoman Heidi Butler.
"As a small consolation," Butler said, college President Mark Erickson arranged to have umbrellas served in cafeteria drinks so students "can pretend they're on spring break."
