Heavy snow impacted road and air travel late Friday and early Saturday. Roughly 115 million people are under some form of a winter storm warning or advisory across the United States. Nearly 2,000 flights involving domestic airports having been canceled, according to the flight-tracking site FlightAware.com. Forecasters expect a substantial amount of precipitation Saturday evening through Sunday up and down the East Coast. The latest model forecast indicates snow starting Saturday evening in Boston and New York, which will then turn into a wintry mix and freezing rain overnight into Sunday.
The National Weather Service in New York is forecasting 3 to 6 inches of sleet and snow plus possible ice. Boston could get more than 6 inches of snow. Winter storm watches are already posted for upstate and inland New England. The Interstate 95 corridor through New England seems to be where the bulk of the ice will form. Connecticut, Rhode Island and Massachusetts will be affected. The extreme cold follows the storm and moves into the rest of the Eastern United States on Monday. Arctic air will spill out across the country later next week.
