A look at Super Bowl weather history and some interesting tornado statistics for it

The biggest sporting event of the year is of course the Super Bowl and no doubt this year’s matchup between the Pittsburgh Steelers and the Arizona Cardinals is sure to be no different.  Super Bowl XLIII will be held in Tampa Bay, Florida and the weather forecast is looking to be just about perfect – see our game day forecast below.

What about Super Bowl’s in the past?  Was there ever any notable weather during the big game?  You bet there was.  Here are some fun facts (courtesy wx-man.com):

  • 17 of 42 Super Bowls played indoors
  • 16 of 42 Super Bowls had a trace or more of rain nearby
  • 2 Super Bowls had snow on game day (1982,2006)
  • 1 Super Bowl played during an ice storm (2000)
  • Warmest high temperature of 82° (1973,2003)
  • Coldest high temp for dome game 16° (1982)
  • Coldest high temp for non-dome game 49° (1985)
  • Wettest Super Bowl .92 inches (2007)
  • Outside games with high wind gust (1980, 1984, 1989,2007)

You will notice there isn’t really any mention of severe weather in those statistics. The NFL has been pretty fortunate on that front with nothing particularly notable – rain always seems to be the biggest threat.

December 28 to January 3 - This week in Denver weather history.

This week in Denver weather history is very interesting for a couple of reasons.  First is the two year anniversary of the holiday snow storms of 2006 as it was from December 27th to the 28th that the second major storm in a week buried the city even further in a blanket of snow.  Second, we see many occurrences of high winds, some damaging, which reminds us that the winds we have been experiencing and will continued to experience this week aren’t all that unusual.
