Not everyone was able to enjoy a warm Thanksgiving meal Thursday. As Wednesday night’s snowstorm clobbered the Northeast, it left almost half a million homes without power. As of early Thursday morning, total numbers hit 30,000 in Massachusetts, 195,000 in New Hampshire, and 110,000 in Maine, which is bringing in crews from Canada to help with the recovery effort. More than 700 flights were canceled and almost 5,000 were delayed Wednesday as travelers tried to get to their holiday destinations.
