– Aaron Rodgers and the Green Bay Packers were rolling along with a big lead, looking as if they would take another step toward a playoff spot and the top of the NFC North.

Once it disappeared, they still found a way to pull out the victory.

Rodgers hit Jordy Nelson with a 60-yard pass to set up Mason Crosby's 32-yard field goal as time expired, lifting the Packers to a 30-27 victory over the Bears on Sunday in one of the coldest games ever played in Chicago.

Wide receiver-turned-running back Ty Montgomery ran for a career-high 162 yards and two touchdowns. Micah Hyde broke up a potential go-ahead touchdown pass, and the Packers (8-6) took their fourth consecutive victory despite blowing a 27-10 lead in the fourth quarter.

They also moved ahead of the Vikings for sole possession of second place in the NFC North and pulled within a game of division leader Detroit, with the Vikings getting pounded by Indianapolis and the Lions losing to the New York Giants.

"I think we have a lot of grit as a team," Rodgers said. "We stick together in adverse situations. There wasn't any finger pointing after 27-10 turned into 27-27 for either side. We just knew we had to go out and make something happen. It's fun to be standing here at 8-6. We all know what 4-6 felt like. It was tough."

For the Bears (3-11), it was more of the same.

They had tied it on a field goal by Connor Barth with 1:19 left. The Packers took over at their 27, and on third-and-11 at the 26, Rodgers unleashed a deep pass down the middle of the field to Nelson, who got behind Cre'Von LeBlanc.

With no timeouts, the Packers downed the ball before Crosby booted his winner.

"The team has a lot of character," Chicago defensive end Akiem Hicks said. "The team has a lot of players who are willing to fight to the end, put everything on the line. This is our life. This is what we do."

All that happened on a day when the game-time temperature was 11 degrees with a minus-4 windchill.

Chicago hosted the Packers in 3-degree temperature and a minus-15 windchill — the lowest ever for a Bears home game — on Dec. 18, 1983.

The Bears' coldest home game according to temperature was against Green Bay on Dec. 22, 2008, when it was 2 degrees with a minus-13 windchill.

Rodgers threw for 252 yards despite problems his left hamstring and right calf that kept him out of practice during the week.

Chicago's Matt Barkley threw for 362 yards and two touchdowns but was picked off three times.
