Almost 0cm of Snow (2018 Edition)

As of April 21st the International Airport has dropped to "Trace" amounts of snow on the ground:

The whole melt took two weeks, starting on April 8th at 31cm, and falling to almost-0 on the 21st.

Blatchford appears in this chart in green, and it hit 0cm on April 20th.

Last winter we marked this event exactly one month earlier, with the Airport hitting trace amounts on March 21st. That is show by the red, dashed line. Last winter there were some spring snowstorms though, which bumped things up again in April.

So the airport hasn't officially hit 0cm yet, but assuming that happens today then it will be pretty late, but not really late. We're still about a week ahead of when the snow first hit 0cm in 2013, 2011 and 2002. But in the last three years 2015, 2016 and 2017 were all really early winters, and we're several weeks behind those.
