The coldest air is moving away, and temperatures will rebound dramatically over the next few days.
This is good timing, with the weekend just ahead!
Polar vortex recap
The Minnesota State Climatology Office has compiled a recap of our latest polar vortex episode.
Some details of their summary:
The -56 degrees F air temperature at Cotton 3S on January 28, 2019 was the coldest ambient air temperature in Minnesota since the -60 degrees F reading near Tower on February 2, 1996.
The -28 degrees F air temperature in the Twin Cities on January 30, 2019 was the coldest ambient air temperate in the Twin Cities since -32 degrees F on February 2, 1996.
The -13 degrees F maximum temperature on January 30, 2019 was the coldest maximum temperate since -17 degrees F on February 2, 1996.
Neither the minimum or maximum temperature in the Twin Cities on January 30 set a record for the date. However, the -56 at Cotton on January 27 did set the daily statewide record minimum temperature for the date. The old record was -54 at Pokegama Dam in 1904. Cotton 3S also saw -56 degrees F on January 31, breaking the daily statewide record minimum temperature for the date as well. The old record was -55 degrees F at Embarrass in 1996.
Some record cold maximum temperature records were set across the state as the mercury stayed in the teens below zero on January 30. Some of these records include: -14 degrees F at Duluth, -19 degrees F at Rochester and International Falls and -17 degrees F at St. Cloud.
Their recap also has a detailed discussion about the wind chills over the past few days.
