Eagles-Packers weather report: How cold is Lambeau going to be?

The Philadelphia Eagles and Green Bay Packers won't just be battling each other when they face off at 4:25 PM EST on Sunday. Both teams will also be fighting against the bitter Wisconsin cold. For the Eagles, it'll be the chilliest game they've had to play in so far this season.

While it's certainly cold enough for snow, the forecast doesn't project much precipitation. It's just going to be cold with temperatures in the 20's and wind chills in the teens.

According to Tim McManus of Birds 24/7, Philadelphia's players are well-prepared to handle the conditions. Some Eagles players will be wearing wet suits when they take the field on Sunday afternoon.

Zach Ertz looked as if he was coming from the beach rather than the practice field as he stood at his locker yesterday. He and some of his teammates plan on wearing a wet suit vest under their jerseys to combat the Lambeau cold Sunday, and the tight end had just finished taking it out for a test drive.

Does it help?

"Yeah. Everyone was saying it was so cold but I didn't notice it at all with that thing on," said Ertz. "I think it helped a lot."

Is this more Chip Kelly sports science at work? Actually, no. Malcolm Jenkins gets the credit for this one. Apparently, many of the Saints players wore wet suits underneath their uniforms for the playoff game in Philly last January. He recommended it to his Eagles teammates, and the idea became pretty popular in the locker room.

(That Malcolm Jenkins signing just continues to look better and better, huh?)

Anyway, it'll be interesting to see if the cold temperature has any impact on the game. It's not as if the Eagles play in a warm weather city so they should be able to handle the temperatures. The performance of rookie kicker Cody Parkey, a Jupiter, Florida native, however, might bear watching.

Here's a look at Lambeau Field, home of the frozen tundra, just hours before kickoff. As you can see, it snowed in Green Bay on Saturday evening.
