La Nina to blame for snow



Looking out the window, I can't help wondering when we moved to the North Pole? Not that I need to tell you about the weather ... it's brutal, lots of shoveling, everything is closed, etc.

What's interesting is that today's storm actually started a few thousand miles away in the Pacific Ocean along the equator. Known as La Nina (the opposite of El Nino) The water there is unseasonably cold, and that sets in motion a weather pattern that, historically, means a wet winter for us.

It also sets the stage for violent weather, like today's tragic tornadoes in the South (and the January tornadoes in Kenosha County).

(Here's a story I wrote with more background on La Nina, plus the Wikipedia page with more info.)
