More specifically, La Niña conditions now exist in the tropical Pacific Ocean. That means sea surface temperatures in the equatorial Pacific are running cooler than average across a large region. 

The National Oceanic and Atmospheric Administration has issued a La Niña advisory. 

 about the statistical significance of La Niña winters in Minnesota. Climatologically, La Niña winters skew colder and snowier than average. 

Right now, NOAA’s three-month temperature outlook for meteorological winter (December-February) favors equal chances for warmer and colder than average temperatures this winter across Minnesota. 

NOAA’s precipitation outlook favors above-average precipitation from December through February.

Minnesota winters have warmed about 5 degrees on average since 1970 due to climate change. Keep in mind that even though our winters are considerably milder on average, it’s still below freezing and cold enough for snow most of the winter. 

If this winter brings a typical La Niña pattern, we could see more than our fair share of snowfall this winter. 

Here’s a look at average annual snowfall across Minnesota between 1981 and 2010. It ranges from around 30 inches in western Minnesota, to over 90 inches on the ridges above the North Shore.

The 30-year annual snowfall average in the Twin Cities is 54.4 inches.
