That was the message from Pete Petoniak, a meteorologist with Green Bay's Fox television affiliate, WLUK-TV Channel 11.
"If you're heading to the Packers game, get ready for even colder and windier conditions than last week. Bring the thermal-lined cheesehead," Petoniak wrote in his daily forecast that's printed in The Green Bay News-Chronicle.
Sunday's high is supposed to top out at 9.
Star Jacksonville receiver Jimmy Smith was looking forward to Green Bay's famed frigid weather. That was Wednesday morning, however, when he was told predicted highs were the mid-20s.
"A game is a game and the cold weather isn't going to bother me," Smith said. "Cold is cold, hot is hot. I have just as much trouble with the heat as I do with the cold. It'll be fine. I've always dreamed about playing in Lambeau Field and the cold. It's just the way it is up there."
Jaguars quarterback Byron Leftwich knows a little something about playing in the cold since he starred collegiately at Marshall, which is located in West Virginia. Playing on the frozen tundra will be a dream come true, he says.
"It's one of those things when you're growing up as a kid, you always wish you can play in this league and have an opportunity to play in a stadium like that," Leftwich said. "And every time you ever dream about playing in Green Bay, it's never been warm."
Leftwich, of course, will be matched by the kind of cold weather. By beating Detroit with a flaming-hot second half last week, Packers quarterback Brett Favre upped his career record to 38-1 in home games played in temperatures of 35 or below.
"I think both of our arms are weatherproof," Leftwich said during a teleconference with Wisconsin media. "I think both of us have enough arm strength to be able to throw through the bad weather."
Jaguars coach Jack Del Rio was thrilled with Mother Nature's timing in sending record cold to Florida. The weather, however, won't mean a thing once the game starts, he says.
"You get your equipment right, and then you get your mind right and go out and compete," Del Rio said. "That's what we're going to do Sunday. Good football teams play good football late in the year, and it happens to get cold this time of year."
