Atlanta weather | Chilly morning with warm-up to come

Some metro Atlantans awoke to frost, but forecasters predict a significant warming trend through the weekend.

Channel 2 Action News meteorologist Karen Minton said temperatures around the region dipped into the 30s early Thursday morning.

But expect a change, she said.

“We’ll have a big warm-up,” Minton said. “Seventies are back.”

The mercury will climb to the low-60s by Thursday afternoon, she said, but an unseasonably high 77 degrees is expected by Saturday afternoon.

Elsewhere, the superstorm that was Hurricane Sandy has churned its way north of the U.S. border, forecasters say. And more flights to the hard-hit New York City region are expected to leave Hartsfield-Jackson Atlanta International Airport on Thursday, airline officials said.

Atlanta-based Delta Air Lines resumed roughly half of its flights to John F. Kennedy International Airport in New York on Wednesday, and anticipates restarting flights to New York’s LaGuardia International Airport, operating more than 50 percent of its usual schedule, Delta officials said.
