Winter storm snarls thousands of flights in the Northeast and Great Lakes. Maps show the latest forecast.

More than 2,000 flights were canceled or delayed across the Northeast and Great Lakes regions on Saturday after a winter storm packing ice and snow slammed the area during the busy travel period between Christmas and New Year’s.

As of Saturday morning, New York City had received just under three inches of snow — roughly half of what some forecasts had predicted.

Least 2,700 flights have been canceled across the U.S. since Friday, and thousands more were delayed, according to the flight-tracking website FlightAware. 

Newark Liberty International Airport, John F. Kennedy International Airport and LaGuardia Airport posted snow warnings on the social media platform X on Friday, cautioning that weather conditions could cause flight disruptions.

Ahead of the storm, New York Gov. Kathy Hochul declared a state of emergency for more than half of the state. She told CBS News New York in a phone interview Friday afternoon that people in the region should delay their travel plans.

“If you can stay off the roads for just a few more hours, delay your travel plans, and allow our plows to get out there and do what they do,” Hochul said. “If people are staying home, it’s just a volume of snow, we’ll be able to get through it. New Yorkers are tough, we’ve been through this before.” 

The National Weather Service warned of hazardous travel conditions from the Great Lakes through the northern mid-Atlantic and southern New England, with the potential for tree damage and power outages. Forecasters said the storm was expected to weaken by Saturday morning.

Snow will continue into the northern and central Rockies and nearby High Plains this weekend; however, a fast-moving system will limit snowfall amounts overall.

In the Northern Plains, arctic air will surge south on Saturday behind a strong cold front. CBS Philadelphia meteorologist Andrew Kozak said it will be some of the coldest air yet this season. Temperatures will drop below zero in parts of Montana by Sunday morning and wind chills will fall below minus 30 degrees with gusty winds.
