Minnesota, Wisconsin and Michigan Face South-Shifting Snow Systems as New ECMWF Model Shows Developing Snow Hole in the Upper Midwest
UPPER MIDWEST — Newly updated Wednesday afternoon model guidance shows that two upcoming clipper systems—one Thursday night and another on Saturday—may shift south of Minnesota, Wisconsin and Michigan, creating a developing snow hole across the region. The latest ECMWF snowfall map highlights very limited accumulation over these states, surrounded by heavier totals to the north and west.
ECMWF Model Shows Both Clippers Tracking South of the Region
The ECMWF snowfall projection displays widespread low snow totals across Minnesota, Wisconsin and Michigan, with far higher accumulations appearing in surrounding areas:
- Heavy snow bands positioned north of Minnesota
- Moderate to heavy snowfall stretching west into the Plains
- Light to minimal totals across the central portions of the three states
Forecasters note that the ECMWF has consistently shown this southward trend, reducing the likelihood that either system will bring meaningful snow to the Upper Midwest.
Model Disagreement Remains Until System Enters the U.S.
Despite the ECMWF trend, the HRRR model does not fully support this southern shift, maintaining a more northern track.
Because the core disturbance is still outside the United States, meteorologists caution that confidence remains low until the shortwave energy moves inland and can be sampled directly.
This means snow chances may still shift in either direction over the next 24–36 hours.
A Warm-Up Is Expected After a Brutally Cold Weekend
Regardless of snowfall outcomes, temperature guidance remains more certain:
- A sharp, bitter cold outbreak will affect the Upper Midwest this weekend.
- Shortly after, models show a noticeable warm-up, easing conditions heading into Christmas week.
This warming trend may further limit snow potential in Minnesota, Wisconsin and Michigan in the immediate future.
