Largest Snowflake World Record As A Google Logo

This is a bit weird for a Google logo but weird does not surprise me for Google.

Today's Google logo celebrates the day of the sighting of the largest snowflake every spotted. Google says it is the world record for the largest observed snowflake.

Here is the Google snowflake logo - how huge?

Here is a video of it:

Wikipedia has the largest snowflake as 38 centimeters (15 in) in diameter observed in Fort Keogh, Montana on January 28, 1887.

Why would Google have a logo for a snowflake?

Hard to say, Google did tweet:

We couldn't flake on this one... twitter.com/GoogleDoodles/…
