Memories of the schizophrenic 2013/2014 last winter season still linger. While most of the country suffered through the deepest freeze in two decades, folks west of the Rockies suffered through record-setting heat and drought.

As winter approaches once again, you’re probably wondering if Mother Nature will deliver more of the same.

The short answer: no and yes.
