Snow is totally interesting to watch in its various stages. My NT wife is into this as well. This is a shared interest we have.
She particularly loves all the patterns ( fractals? ) like rounded triangles, in ice. The kind you find in shoe- prints in frozen mud where the snow melts and refreezes overnight.
Snowdrifts are amazing.
Granulated refrozen snow is interesting.
I saw the last patch of melting snow on someone's back garden today.
