The growing season officially came to an end in most of Winnipeg today with frost as temperatures dipped below zero. The airport dropped to -2.2°C, while temperatures dipped to -1.5°C at my place in south St Vital. Only the downtown area managed to escape frost, with a low of 1.1°C at The Forks and 1.0°C at the University of Winnipeg station.
This first frost however, is later than normal. 1981-2010 normal first frost at the airport is September 24. The temperature actually dipped below zero already yesterday evening, making it the latest first frost of the season since 2005 when we didn't get our first frost until October 6. In case your wondering, this only ties as 12th latest first frost since 1872.
Many parts of the city also saw their first snowflakes of the season yesterday afternoon as lake-effect precipitation moved in. The airport did not record any snow however.
The cold and windy conditions will continue until at least Wednesday. Showers and flurries will be possible each day, but significant accumulations are not expected.
I do have some good news. There are hints of warming up for the Thanksgiving weekend. That may come with some more chances for some rain however.
