Minnesota Thaws: January Warm-Up Breaks Records
15 Jan
Summary
- Minnesota's January thaw means above-freezing temperatures for days.
- A January thaw is defined as two consecutive days above 32 degrees.
- Climate change contributes to Minnesota's January warming trend.
Minnesota is currently experiencing its annual January thaw, a period marked by high temperatures climbing above freezing for multiple consecutive days. This warming trend has become a reliable feature of the state's winter climate, with the Twin Cities recording above-freezing temperatures for at least two days every January for the past 15 years. Some recent thaws have been notably prolonged, with one record-setting stretch extending through mid-February.
This recurring phenomenon is driven by an active jet stream, which facilitates the movement of warm weather systems into the region. Climatologists also highlight that climate change is exacerbating this trend, making January the fastest-warming month in Minnesota. The absence of snow cover due to warmer temperatures can further contribute to rising winter temperatures, creating a snowball effect.
Despite these warmer spells, meteorologists assure that substantial winter weather is still ahead. The January thaw offers a temporary respite, allowing for necessary outdoor maintenance like clearing driveways and sidewalks before subsequent snowstorms arrive. This pattern underscores the dynamic nature of Minnesota's winter weather, influenced by both natural variability and long-term climate shifts.
