Four Letter Word

Forecast for tonight, slight chance.

Saturday, a combination of TWO four-letter words. One not so bad and can be said in mixed company. The other, not so much.

Saturday night, an eighty percent chance of the most vile, despicable word ever created by man. SO vile, coming in piles, you even have to shovel it.

No, not that word. The other four-letter word starting with an 'S'.

SNOW.
