Snow could be piled high around the suburbs this winter, if early predictions of a snowy and wet season prove correct.
A snowier, wetter winter may be in the cards for the Chicago region, according to the latest seasonal outlook from the National Weather Service’s Climate Prediction Center.
The forecast shows that — along with a wide swath of the Midwest, including Indiana and much of Ohio — Illinois could see more precipitation than normal, while temperatures are predicted to remain near average levels.
One of the strongest indicators of a wet Chicago winter is the earth is in its third year of the naturally occurring weather phenomenon known as La Niña, which brings cooler-than-normal sea surface temperatures in the tropical Pacific Ocean.
Its counterpart, El Niño, refers to warmer tropical Pacific sea surface temperatures.
Meteorologist Matthew Rosencrans said current forecasts are “very reflective” of past La Niña winters, which typically have favored above average precipitation for the Great Lakes region.
“On a year-to-year basis, El Niño or La Niña controls about 38% of your variance, and we are in a La Niña, a decently strong one, and very likely to be in a La Niña through the winter,” he said.
However, don’t load up on salt or buy a heavy duty snowblower just yet. Because we’re still four months away from the icy season, the center’s best models for the Midwest have a hit rate of just about 20%,
