Ah yes, the April Fool's blizzard. Never fails.

When I lived in Massachusetts, every year right around April 1st (give or take a few days) there'd be a big old yucky snow/sleet/slush storm to really put the kabosh on things.

It usually happened after everyone has taken off their snow tires, and broke out their shorts and other springtime apparel.

It's nature's way of saying "neener".
