MINNEAPOLIS, Minn. — Winter 2026 could deliver a classic northern deep freeze as a developing La Niña pattern strengthens across the Pacific Ocean. Forecasters say this setup will steer the polar jet stream directly over Minnesota and Wisconsin, sending Arctic air plunging south and triggering frequent snow events.

Cold Air and Snow to Dominate the Season

According to the National Weather Service Twin Cities, a persistent polar jet will dip southward for much of the season, locking the Upper Midwest into a colder, snowier pattern. Residents should prepare for frequent Arctic surges, with wind chills well below zero expected at times.

As reported by Country Herald, the cold air will also enhance lake-effect snow along the Lake Superior shoreline, where bands could deliver heavy bursts and near-whiteout visibility on routes like U.S. 2 and I-94.

Transportation officials are already anticipating an active salting and plowing season lasting through at least mid-February.

Frequent Snows but Fewer Blizzards

While the 2026 La Niña may not bring record-breaking blizzards, meteorologists say it’s likely to produce more frequent, moderate snow events, keeping total accumulation slightly above average across much of Minnesota and northern Wisconsin.

The frequent smaller systems could make travel conditions slippery on a regular basis — posing hazards even without major snowstorms.

Residents Urged to Prepare Early

Emergency managers are advising residents to inspect furnaces and heating systems before temperatures plunge. Drivers are also urged to keep emergency kits, blankets, and chargers in vehicles for potential whiteout conditions.

“This year’s La Niña will bring more of a traditional northern winter — cold, snowy, and relentless,” one Twin Cities forecaster said. “It won’t necessarily break records, but it will keep people on their toes week after week.”

Looking Ahead

La Niña winters typically linger through early March before transitioning toward neutral conditions. For Minnesota and Wisconsin, that means an extended stretch of cold, with little chance of early spring warmth.

If predictions hold, this could be the snowiest and most consistently cold winter the region has experienced in several years.
