The snow caused widespread havoc at the airport, sharply limiting flights, while snarling traffic on clogged roadways and shutting schools, the Hartford (Conn.) Courant reported Thursday.
"It was impressive," said meteorologist Joe Furey. "Two to 4 inches of snow an hour. Lightning and thunder."
The storm was part of a system that dropped heavy snow in the northeast, stranding fliers and drivers. By the time the snow stopped at Bradley, it received 25 inches.
Boston's airport was jammed early Thursday with travelers whose flights were canceled after a blizzard dumped more than 2 feet of snow across New England.
They will soon join an estimated 85,000 other passengers hoping to fly out of Logan International Airport, Massachusetts Port Authority spokesman Phil Orlandella told The Boston Herald.
"We expect this won't clear up until Friday," Orlandella said.
Logan reopened all its runways and airlines said they were recovering but expected to operate with delays and cancellations Thursday, they said.
About 15,000 New England households were without power Thursday, down from a high of more than 100,000 Wednesday, as trees weighed down by the wet snow tumbled onto power lines.
In Connecticut, the Department of Transportation had 820 trucks on the road by 5:30 p.m. Wednesday working to clear the roads before Thursday's commute, said spokesman Kevin Nursick.
"It is an absolute rarity," said Glastonbury Supt. Alan Bookman. "Of course, we don't have storms like this every winter. I think the biggest challenge is where do we put all this snow? Just putting it somewhere will be a major accomplishment. Crews cleaning it now say it's as bad as they've ever seen it."
Much of the six-state region, hit by the same storm that dumped 9 inches on New York, was paralyzed as cleanup efforts were hampered by high winds, especially along the New England coast, officials said.
Amtrak said it planned to operate a normal schedule in New England after repairing storm damage north of New Haven, Conn.
