I debugged this tonight and then finally fixed it. During the time I was playing with it, it stopped the Flurries where I live and I had to use a weather map and pick a different city. From what I can guess, Google only returns "flurries" and not "snowflurries" as in the table. I cannot prove this and it should be harmless to leave "snowflurries", so I just added a flurries entry.

Patch attached.
