A heavy snowstorm and dangerously cold conditions gripped the northeastern United States on Friday, delaying flights, paralyzing road travel and closing schools and government offices across the region. Boston was hardest-hit by the first major winter storm of 2014, getting nearly 14 inches (35 cm) of snow, while some towns north of New England's largest city saw close to two feet (60 cm) of accumulation.

It appears Southern Ontario's weekend reprieve from harsh winter weather will be shorter than first expected.

Environment Canada issued a special weather statement late Friday afternoon that heavy snow is expected for the region on Sunday night, which will be followed by bitter cold and strong winds when kids go back to school Monday morning.

This is more bad news for residents in Toronto and surrounding areas who are still recovering from a Christmas Eve ice storm and bitterly cold temperatures over the past week.

Toronto, Montreal and Quebec suffered temperatures between -21 C and -28 C overnight Friday, with wind chills approaching -40 C. By Friday morning, London, Kitchener, Hamilton and Oshawa all approached record low temperatures — according to Environment Canada, weather stations in Oshawa recorded a temperature of -25.8 C, just a fraction warmer than the city's record low of -26.0 set in 1981.

Quebec set some amazing new record lows during the cold snap. Val d'Or set a new record at -41.6 C on Jan. 2, while Chibougamau dropped all the way to -43.7 C. Rouyn, Murdochville, and Sept-Iles all felt colder than -50 C with the wind chill.

Weekend temperatures from Sarnia up to Ottawa should reach as high as -1 C, which will feel downright balmy. But just as things start to melt, another storm is expected to charge into the region Sunday night, bringing more snow, high winds and cold temperatures.

Environment Canada expects snowfalls of 15 to 20 centimetres in some areas Sunday night, with winds picking up Monday morning. Temperatures are expected to fall to -18 C overnight Monday and reach a high of only -16 C on Tuesday before starting to warm up again Wednesday.

However, things could be worse. Winnipeg isn't expected to warm up over the weekend, and is expecting a daytime high of -29 C on Sunday and lows of -33 C into next week.
