No more -25 deg F or below temperatures at Minneapolis, MN
- The last time temperatures at Minneapolis hit -25 degrees F or below
was Feb. 3, 1996, a period of more than 11 years.
The longest period without a -25 F deg F or below daily minimum at
Minneapolis was just 9 years, from 1924 to 1933 (see figure).
The official period of record at Minneapolis is 1891-current. Pioneer
records at Ft. Snelling go back to 1820.
Both urban urban island (UHI) and climate change forcings are keeping
temperatures at Minneapolis warmer than they used to be. However, even
stations not affected by UHI in other part of the Upper Midwest are
exhibiting similar warming characteristics as at Minneapolis.
My prediction is that there will be no more -25 deg F or below air
temperature readings at Minneapolis mainly because of anthropogenic
greenhouse global warming as it worsens in the years ahead.
