(Minneapolis, MN)  --  Seahawks fans traveling to Minneapolis for this Sunday's wild-card playoff game with the Vikings are being urged to bundle up.  The current Weather Underground forecast for gameday calls for partly cloudy skies, with the temperature at kickoff predicted to be three degrees Fahrenheit.  Forecasters say the temperature could fall to minus 14 as the game progresses, making for one of the coldest contests in NFL history.  The coldest game on record was the "Ice Bowl" in Green Bay between the Packers and Cowboys for the 1967 NFL Championship, when gametime temperatures fell to 15 below zero.
