US Prepared For First Cold-Weather Super Bowl
The Denver Broncos and the Seattle Seahawks will face each other at the first Super Bowl to be played in an unprotected stadium in a cold weather state.
Super Bowl XLVIII, which is being held at the MetLife Stadium in New Jersey, kicks off at 11.30pm UK time.
Weather forecasts suggest the arctic deep freeze affecting much of the North East will have eased slightly by the time the game starts, but temperatures are still expected to hover around freezing.
Both the players and the 80,000 expected fans, who will have to sit in their seats for hours, are being instructed to wrap up warm.
NFL commentator Jeff Ellis said he doesn't expect the temperature to be a factor in the outcome, although the wind might have an effect.
He said: "We're here to watch football.
"I've been surprised this week at all the talk of the weather because we've got the two of best teams in the NFL playing each other.
"They have 13 wins, three losses, both teams with identical records.
"I can't think of the last time we've had the two best teams playing - an old team, a young team; this is really exciting."
The Broncos, led by veteran quarterback Peyton Manning, are currently slim favourites to win.
Such a high profile event on the outskirts of America's largest city presents a huge security challenge.
About 100 different local, state and federal agencies have spent three years planning the security.
Fans arriving at the stadium will be welcomed with airport style metal detectors, bag searches and pat downs.
There is limited parking, so many will arrive by public transport.
NYPD police chief Bill Bratton has insisted that there have been no specific or credible threats to the event, but hundreds of extra security personnel have been deployed across New York and New Jersey train and bus stations.
As his team conducted a high-visibility search of Manhattan's Penn Station, Federal Air Marshal Mike Pascarella told Sky News: "A lot of people are working really hard, in really cold weather, to make sure the game goes off well for everybody.
"We've planned for everything."
He admitted his intelligence teams were "aware" of the recent attacks on transit hubs in Russia in the run up to the Olympics but said: "We're going to focus on what's happening here in New York and in New Jersey for the next few days and protect the folks travelling in and out of the stadium itself."
More than 100 million people are expected to watch the Super Bowl at home.
The National Retail Federation said a recent survey suggested about 44 million Americans will attend a Super Bowl party.
That means a spike in trade for television shops.
Electronics shop Best Buy's TV sales supervisor Wesley Klein said: "People are buying TVs like crazy.
"People get excited, people want to buy large tv sets, people want to feel like they're in the game, but actually at their house.
"They want to host parties and get surround sound, they want the whole feeling of being at the game and at the same time being at the house ... where it's warm."
Viewing from the sofa means getting a good look at the adverts and half time show, which often attract as much attention as the game itself.
Advertisers are reportedly paying more than $4m (£2.4m) for a 30 second slot, and many have launched campaigns advertising the advert.
David Beckham is set to make a semi naked appearance in an ad for his H+M clothing line.
The half-time show is set to be headlined by Grammy Award winner Bruno Mars.
He'll be joined by the rock band The Red Hot Chili Peppers.
Soprano Renee Fleming will be the first ever opera singer to perform the national anthem at the event.
All will be keen to avoid pitfalls of performances past, like Janet Jackson's infamous "nipplegate" incident and Christina Aguilera fluffing the words to the national anthem.
