Is the weather office on crack?

Is it just me or has Environment Canada weather forecasts been WAY off the mark lately?  They say snow - we get sunshine, they say sunshine - we get rain, yadda, yadda...

How do they forecast the weather anyway?  Perhaps the official Environment Canada Weather Dartboard?

Or do they use the amazingly accurate "Wheel 'O Weather"?

Maybe I'm being too hard on the good folks at the weather office.  Maybe in this age of global warming and climate change the weather has become too unpredictable to give us an accurate forecast.  Or maybe they're all on Paula Abdul-like medication.  Thoughts?
