DALLAS (CBSDFW.COM) – There is just over a week until Super Bowl XLV at Cowboys Stadium in Arlington. But there could be a chilly problem. Wintry weather — including snow – is expected to arrive in North Texas on Tuesday, and it could have a major impact on the high-profile events that are planned throughout the week leading up to the big game.

Snow and ice are certainly not the ideal forecast for event planners, who had scheduled numerous parties and festivities around North Texas. The fear is that we could have a replay of last year’s NBA All-Star Game in North Texas, where icy conditions made it difficult to get around town and left a slushy impression on the out-of-state visitors.

Despite the ominous forecast, preparations are still underway for the game itself at Cowboys Stadium and a number of pre-game events around the Metroplex. The stadium field was transformed on Thursday into a home for game rivals – the Green Bay Packers and the Pittsburgh Steelers. And at the Dallas Convention Center, the NFL Experience kicked off with a record-setting crowd.

But as celebrities begin flying into town this week, Old Man Winter could arrive as well, to put the big plans on ice. The snow and ice are expected to become a problem starting on Tuesday night, and temperatures could remain in the 20s for two straight days. (Click here for the latest weather forecast.)

The threat of winter weather has always presented a concern for the host committee. There is certainly a game plan ready to go, or being developed, to defend the city and the scheduled events from this ill-timed cold snap. But if conditions become too treacherous, the weather could put a serious freeze on the fun.
