At Minneapolis it is usually Jan 19 to 25, with a normal low of 8°F. At the other reference stations: Rochester Jan 20 to 26 (6°F), Duluth Jan 19 to 25 (2°F) and International Falls Jan 21 to 27 (−7°F). These are NOAA's 1991 to 2020 daily normals.
The normal low at Minneapolis reaches 32°F around Nov 7 and 20°F around Dec 3. The first actual freeze came around Oct 24 in the median of the last 10 winters, weeks ahead of the normal, because one clear calm night can run far below the average.

At Minneapolis a typical recent winter brings 152 nights at 32°F or colder, 72 at 20°F or colder and 19 at zero or colder, the median of the last 10 seasons.
Each night's forecast low is compared with the NOAA normal low for that date at the nearest reference station. A night 20 or more degrees below normal is an arctic blast, and so is a night below zero where the normal low is 10°F or warmer. A night 10 to 19 below is a cold snap. A night 5 or more below, or a week that runs 3 or more below on average, is colder than normal, and a week 5 or more above is mild.
The normal lows and coldest weeks are NOAA's 1991 to 2020 daily climate normals for Minneapolis St. Paul Airport (USW00014922), Rochester International Airport (USW00014925), Duluth (USW00014913) and Falls International Airport (USW00014918). The recent winters, first dates and records come from the same stations' daily lows in NOAA's GHCN-Daily archive, the winters of 2016 to 2017 through 2025 to 2026. The 7 night forecast is the National Weather Service's and the outlook is the Climate Prediction Center's.
