The second Super Bowl to be played in Minnesota is scheduled for February 4, 2018. While the temperature will be controlled inside the stadium, the weather outside can vary greatly. Looking at statistics for Twin Cities over the past 140 or so years on February 4th, the temperature has ranged from a maximum of 51 degrees in 2005 to a minimum of -28 in 1886.
The 1981-2010 normal temperatures for February 4th at the Twin Cities International Airport are 26 degrees for the high and nine degrees for the low. February is not typically a very snowy month. The most snow on February 4th in the Twin Cities is 4.4 inches in 1971.
In reality, the weather for the first week of February can vary greatly. At times, it can be the coldest part of the winter and "sporting" some of the deepest snow depths. The chances of seeing no snow cover occurs in about 1 in 10 years. Having a snow depth of about six inches happens about half the time and having at least a foot of snow on the ground is about 15% of the time. It is also the time of year that the length of day light becomes noticeably longer. By February 4, there is about one hour and fifteen minutes of extra daylight since December 21. On February 4, 2018 the sun will rise at 7:29 am and set at 5:25pm, Central Standard Time in the Twin Cities.
The last time there was a Super Bowl in Minnesota was on January 26, 1992 at the Hubert H. Humphrey Metrodome. The high temperature that day at the Twin Cities International Airport was 26 degrees and the low temperature was seven. The day was dry, but 1.3 inches of snow fell the day before. The snow depth was ten inches on January 26, giving the outdoor scenery a decidedly wintry look and feel.
