Winter Outlook – More Snow

October 19, 2017 0 Comments

The National Oceanic and Atmospheric Administration (NOAA) has released its winter outlook for 2017-2018 and it includes more snow than normal for central Illinois.  La Nina, which is a periodical cooling of the Pacific, is the culprit.  Her brother, El Nino, which is a periodical warming of the Pacific, brings mild winters with below normal snowfall like we’ve seen the past 2 seasons.  Areas will see above normal snowfall are the Great Lakes and Northwest.  La Nina winters may bring more frequent snows but most of the time they’re snows that won’t bury us.

Regarding temperatures, the Midwest is in the “Equal Chances” category, meaning there’s not enough evidence of a bitterly cold winter or a mild winter.  Usually our temperatures are up and down and some La Nina winters have produced milder winters.

But La Nina is hard to pin down because unlike her brother El Nino, she doesn’t come around as often.

Here are more detailed characteristics of an La Nina winter in Illinois.

So, based on research and consultation with some of the nation’s leading long range forecasters, here’s what I think about snow this winter.  Weigh in with your own thoughts!
