Snow fertile.
Snow is the poor man’s fertilizer, and good crops will follow a winter of heavy snowfall.
Snow trees.
If the first snow sticks to the trees, it foretells a bountiful harvest.
Snowball.
Cut a snowball in halves: if it is wet inside, the snow will pass off with rain; if it is dry inside, the snow will be melted by the sun.
Snow-flakes.
If the snow-flakes increase in size, a thaw will follow.
Snow-moon.
If a snow-storm begins when the moon is young, the rising of the moon will clear away the snow.
