There's a perfect example of why you should wipe snow and ice off your
airplane sitting up at KSTE. So much ice and snow had accumulated on the
tail of a 172 there that the nose gear is completely off the ground and the
tail is laying on the ground frozen in a drift.

Think about what happens when the snow partially melts and then refreezes
INSIDE the airplane. Not everything melts and simply drains away.
