To understand when the polar vortex impacted Michigan, it's important to consider two possibilities:
1. Major Disruptions:
The most dramatic events are major disruptions where the polar vortex weakens significantly, allowing cold air to escape southward and cause extreme cold snaps. Michigan has experienced notable events of this type in:
- January 2019: One of the most severe disruptions led to record-breaking low temperatures and wind chills in Michigan, lasting through late January and early February.
- February 2021: Another significant event brought freezing temperatures and heavy snowfall to Michigan, although not as severe as 2019.
2. Smaller Fluctuations:
The polar vortex is constantly expanding and contracting throughout winter, leading to smaller fluctuations in temperature and wind patterns. These shifts don't often make national news but can still cause colder periods in Michigan.
Therefore, pinpointing a specific "when" for the polar vortex in Michigan depends on your definition of the event. If you're looking for those major disruptions, January 2019 and February 2021 stand out. However, smaller fluctuations occur throughout winter, even in years without major disruptions.
