If the New Orleans Saints want to win their seventh game in a row Sunday, they'll have to beat the Buffalo Bills -- and the cold weather.

Temperatures in the Buffalo area this week will stay in the 40s, and snow is in Friday's forecast with a low of 22 degrees, according to the National Weather Service. Saturday's temperatures will be in the 20s and 30s.

Sunday doesn't look quite as cold with a forecast high of 43 degrees. It's still a little too soon to know what the wind will be like at Ralph Wilson Stadium.

The last time New Orleans played in Buffalo, the Saints blew out the Bills, 27-7. Temperatures were in the 60s.

Critics have poked at New Orleans and QB Drew Brees in the past for their struggles in cold-weather games. Before the Saints downed the Philadephia Eagles in a January 2014 playoff game with temperatures in the 20s at kickoff, ESPN research showed Brees was 2-3 in games played at 32 degrees or lower in his career, completing 61 percent of his passes and throwing for 260.8 yards per game, 10 touchdowns and six interceptions.

Regardless of the weather, the Bills (5-3) are on a roll at home, having won their first four games of the season as they sit second in the AFC East division standings behind the New England Patriots.
