MINNEAPOLIS (WCCO) — The NOAA Climate Prediction Center put the U.S. under a La Niña Advisory Thursday, which could mean a wet — meaning snowy — and cold winter to Minnesota and Wisconsin.
WCCO meteorologist Mike Augustyniak says the forecast comes with a word of caution, because not all La Niñas are equal.
“This La Niña is forecast to be moderate in strength, as opposed to strong, and that makes us a little less confident in how the long-range winter forecast will play out,” he said.
Back-to-back moderate La Niña years during the winters of 2016-17 and 2017-18 produced the sixth warmest winter on record in Minnesota, and a significantly colder-than-average winter in Minnesota, respectively. Both winters did feature above-average precipitation, however.
La Niña is here, with a #LaNina Advisory now in effect. The observed La Niña conditions are likely to continue through the Northern Hemisphere winter (~75% chance). https://t.co/5zlzaYJ1Lp pic.twitter.com/jU6lzWOmHj

La Niña is not the only weather pattern that contributes to how our winter plays out.
