The WunderBlog post for yesterday has a story about the incredibly early snow melt that occurred this year in Barrow, Alaska.  This is usually one of the last places in the US to lose its snow cover.  But this year, due to unrelenting heat, the snow cover disappeared on May 10, a full ten days earlier than the previous record from 2002 (records have been kept there for 73 years).  You can read more about it at https://www.wunderground.com/news/arctic-circle-earliest-snowmelt-ever#prclt-3jeE1T2P.
