It snows here sometimes;
Sometimes we have snowstorms;
And we also have blizzards, but rarely.
If we have ice storms, followed by snowstorms,
And the sun comes out and melts all of the snow in one part of the school district,
But fails to melt some of it in another where ice remains on a few bus routes...
Then conceivably:

School's out with no snow! (At least as far as my eye can see in my school's neighborhood.)

Crrraaaaaaaazy!
