Don't put away those winter boots just yet. Winter storm Niko made good on that Groundhog's Day promise for more winter, dumping record-setting levels of snow, and even some cases of thundersnow, across the northeast Thursday.

The explosive storm, which rolled in and out in a hurry, left at least one person dead in New York, left more than 57,000 without power in Massachusetts and left thousands stranded as more than 3,700 flights were cancelled across the U.S., with nearly 1,800 of those flights cancelled at New York's three main local airports. Hundreds of schools were closed Thursday in Boston, Pennsylvania, New Jersey and New York.

According to the Weather Channel, some areas saw record-breaking snowfall, with extreme rates per hour. Islip, New York, which picked up 13.7 inches total Thursday, and broke a daily snowfall record for Feb. 9. The original record was 11.1 inches, set in 2013. 

The New York Times reported that New England was hit the hardest. With winds exceeding 35mph and visibility down to less than a quarter of a mile, the storm was upgraded to a full-blown blizzard in Massachusetts. Despite the weather, Boston's transit system, which has undergone heavy weatherization upgrades, maintained service without a hitch. The acting general manager of Boston's transit authority, Brian Shortsleeve, said that despite the weather, the transit system was "running smoothly across the board," according to the Times.
