The annual course of 60-day temperature persistence for Minneapolis-St. Paul, Minnesota is examined at five -clay intervals for the last 110 years. Results show maximum persistence for the 60-day periods February 20 to April 20 and June 25 to August 23. Minimum persistence is observed for sequences whose midpoints correspond to late April, late September and mid-November. This suggests the presence of a single favored regime-breaking period for the winter to summer transition and two such periods for summer to winter.
