Winter not over in upper Midwest, New England New England mountains should see up to 14 inches of precipitation A tornado hits a Tennessee county on Monday afternoon (CNN) -- The official start of spring is just a day away. But, along parts of the upper Midwest and Canada, winter plans to stretch its last hurrah until the waning minutes. Fourteen inches of snow are forecast for the mountains of New England on Tuesday, prompting school closures from Massachusetts to Maine. With all the snow this winter, the Worchester, Massachusetts, school system has already burned through the five snow days built into the schedule and will have to make up two more at the end of the year. In Boston, the forecast was much more reasonable, but still troublesome with 3 to 6 inches of snow and sleet forecast before rain begins to fall Tuesday night. Boston's mayor called on city commuters to use public transportation when possible to leave the roads clear for public works crews to do their job. The story will be much the same in Worchester, about 40 miles to the west, where the city is on pace to have the fifth snowiest season on record, CNN affiliate WHDH-TV reported. All it needs is just another 4 inches of snow on Tuesday. "It's kind of becoming old hat because it seems every week we're getting clobbered," resident Bonnie Narcisi told the station. Air traffic snarled On Monday, low visibility caused delays of more than an hour at Newark International, John F. Kennedy International and LaGuardia airports in the New York area. And while fewer than 300 flights were canceled Monday, delays are expected Tuesday at airports from Ohio to New York. Roads unsafe In some areas of Minnesota, Wisconsin and Michigan, up to 5 inches of snow were forecast. Thunderstorms and tornadoes In the South, the precipitation was liquid, but just as blustery. Heavy rains associated with the system provided welcome relief for firefighters, helping to douse a 260-acre wildfire, near the east Tennessee mountain resort town of Pigeon Forge. Only five acres were burning late Monday, Tennessee Emergency Management Agency Director James Bassham told CNN affiliate WATE. The wildfire destroyed more than 60 cabins, WATE reported.
