January 30, 2019 - Cold!
Coldest day in Winnipeg in almost 12 years. February 5, 2007 we hit -41.7C. This morning we got down to -39.9C (or -40.0C) depending on the weather station at the airport. My sensor saw -37.6C. The 'warm spells' are the heat from the HRV unit - which is exhausting warm air from the house about 3m away from the temperature sensor.
