This is certainly the fun part that comes along with having the archived historical daily weather data for Oshkosh! The data archive goes back to 1894. This winter has claimed a spot the history books!

Recognizing the significance of this winters behaviors in categories of mean temperature and the amount of days with maximum temperatures above freezing is crucial. Adding snowfall total and days with measurable snowfall to the comparison the 2011-12 winter becomes one for the ages.

Note: Many seasons have missing snow or precipitation data. For an example, no snow was recorded in the seasons of 1900-1901, 1981-1982, and 1982-1983. Because of this I have added the amount of observations for precipitation and snowfall each season to the rankings.

After analyzing the data it seems this type of "lacking snowfall" we have experienced in 2011-12 actually occurs about a third of the time in a span of the last 30 years. The stat took me by surprise a little bit. The daily measurable snowfall category seems legit as it is in the top 3rd. We here at OSNW3 are very dedicated to our daily observations and when it snows we strive to get a measurement as often as possible. We all know it's been mild and where this winter ranks in the temperature category is expected. Very near the top for warmth.
