What's with the weather

It has been freezing here forever, it is the middle of May and we are still using the heat. Last weekend we got snow, yes the white frozen stuff what's with that. I can't get over it, usually by this time in the spring the trees are turning green and we have blooms everywhere but this year there isn't any sign of buds anywhere. I can even remember that I had mowed the lawn at least 3 times by the long weekend last year and this year, not even close. Will spring let alone summer ever come this year?
