Record Long Snow-Free Streak in Lincoln, NE

Record Longest Streak of Snow-Free Days in Lincoln, NE!

Photo (December 11, 2012)  looking out from Hardin Hall, East Campus, UNL toward
the city center and City Campus of UNL.  Note the green lawns as we approach
mid-December with no measurable snowfall yet this Autumn.

 The "snow-free streak" is defined as the length of time between the last measurable snowfall in the Winter/Spring until the first measurable snowfall in the following Autumn/Winter.

The previous record of 295 days was set in 2004 with the snow-free season extending from February 6 to November 28, 2004.

The last measurable snowfall in Lincoln this year was on February 13, 2012, with 1.1 inches. The period of snow-free days this year reached 295 days as of December 4, 2012, tying the record.   Lincoln remained snow-free as of December 5 setting a new record of 296 snow-free days.  This record has continued  to increase. As of December 11, 2012 the snow-free streak has been extended to 302 days. 

We are not alone with this weather anomaly since Omaha and Norfolk are also experiencing their longest observed streak of snow-free days
