State High School Boys Basketball Tournament Snowstorm
There's been a long-standing myth of the "Tournament Snowstorm." The myth goes that the Twin Cities will get a big snowstorm during tournament time. In particular, during the State High School Boys Basketball Tournament. This myth has been around for many years. In 1975, Bruce Watson notes in his book: WCCO Weather Almanac 1975 that "The State Basketball Tournament Storm" is no myth. We simply get a lot of storms around the equinox, the general time of the tournament." Indeed, in the 25 years before 1975 there were several large snowstorms that occurred around the basketball tournament. Some of the most memorable were: 13.7 inches on March 22, 1952 and 11.4 inches were on March 23, 1966. It was storms like these that perpetuated the myth. The last time 4 inches or more of snow has accumulated in the Twin Cities during the Boy's Basketball Tournament was in 2005.
How often does it snow 4 inches or more during the State High School Boy's Basketball Tournament? The tournament began in 1913 and in those days was 3 days long. Later the tournament expanded to cover 5 days by the 1990's. Snow events were looked at for each day of the tournament. The number of times 4 inches or more fell during the tournament were noted over the past 92 years. Meteorologist Ron Trenda provided the initial research through 1987 and the State Climatology Office continued the check through the year 2005. Here are the results:
In addition, the chances of having a balmy day of at least 50 was looked at. Here are the results:
38 years out of 93 had at least one temperature of 50 or greater during "tourney time." This means that there is a 41% chance of seeing a 50 degree or warmer temperature during the tournament. We've been four times as likely to see 50 degrees rather than 4 inches or more of snow during the tournament!
