The Old Farmer's Almanac, that indispensable US bible for everything from full moons to the optimum planting date for a carrot, forecast last autumn that a gigantic storm would strike New York at the approximate point of, well, now.
As it transpired, the polar vortex - or "Snow-pocalypse", to use Weather Channel-speak - materialised early to leave Manhattan in its numbing Siberian grip. The city's maiden Super Bowl can forge ahead this weekend without the need for sled-pulling huskies, even if the night-time temperatures are enough to make the polar bear atop the Glacier Mint blanch.
Each journalist at the 48th Super Bowl is being issued with gloves and the none-too-subtle suggestion that, come Sunday, the MetLife Stadium will be reimagined as a multi-storey igloo. We seem certain to surpass the game's record low of 4F (-15.5C), registered in New Orleans in 1972 - not as cold, admittedly, as the "Ice Bowl" of 1967, when Green Bay and Dallas staged a conference play-off in a blizzard so bitter that the marching bands' instruments froze, but sufficiently frigid to ask why the National Football League would bring sport's gaudiest showpiece to a region hardly renowned for its balmy Januarys.
Quarterback Joe Flacco, who propelled the Baltimore Ravens to a second Super Bowl 12 months ago, describes the idea as "stupid". Terry Bradshaw, formerly of the Pittsburgh Steelers and one of only two men to have won four, argues: "I don't think you should be putting Super Bowls in northern cities in wintertime."
Harsh conditions supposedly confer an unreasonable advantage upon teams with a strong running game, although it is refreshing to discover that the protagonists themselves harbour few such petty qualms. As Seattle Seahawks safety Earl Thomas puts it, ahead of the collision with Peyton Manning's Denver Broncos: "Little kids love to play in the mud and the snow. That's just how I am. I don't care."
