Every year in the mid-west it snows and temperatures drop a lot. I am from Missouri and temperatures usually drop to -10 alteast once and there usually are many days where it would be below zero. This year it has been a lot different atleast in the mid-west, its more than often sunny and it isn't that cold.<p>I don't see any articles on why this "anomaly", any one has any thoughts on this or any articles that explain why?
