Update: Kickoff still 1 p.m. ET at Metrodome

As of Saturday evening, the NFL was still planning to maintain its original 1 p.m. ET kickoff for Sunday's game between the Minnesota Vikings and New York Giants. But via Twitter, league spokesman Greg Aiello said a final scheduling decision had not been made.

As you know, a blizzard has dropped more than a foot of snow on the Twin Cities and forced a rare closing of Minneapolis-St. Paul Airport. The Giants were diverted to Kansas City and are spending the night there with plans for a 7 a.m. ET wakeup call Sunday. Their charter flight is scheduled to depart at 9 a.m. ET. If all goes well, the Giants would arrive in Minnesota about three hours before game time.

That's a pretty tight schedule, especially considering that Hennepin County (Minn.) pulled its snowplows from the roads earlier Saturday because of impassable conditions. The Minnesota Department of Transportation is advising against any sort of travel Saturday night in what are expected to be whiteout conditions.

The National Weather Service has extended its winter storm warning through 7 a.m. ET Sunday morning. I realize that changing an NFL game time is a big deal and requires huge logistical shifts. But if you're planning to attend Sunday's game, make sure you check and recheck the news before you leave. The kickoff time remains a very fluid situation.
