Many parts of the Northwest Territories will see overnight lows drop below -30C later this week, Environment and Climate Change Canada forecasts suggest.
In Yellowknife, temperatures are forecast to dip to around -30C on each of Thursday, Friday, and Saturday nights, with daytime highs only reaching -25C.
That cold weather is expected to last throughout the weekend.
Fort Simpson is likely to be one of the territory's cold spots in the coming days. The Dehcho community is expected to dip to -33C overnight on Saturday into Sunday, with similarly cold nights on Thursday and Friday.
Fort Smith is also expected to hit -30C on Saturday night, though Hay River is forecast to be a few degrees warmer.
Norman Wells' Saturday night forecast is for -32C. Colder temperatures are expected to reach the Sahtu a little earlier than most other places, with the community facing -30C by Wednesday evening.
At the moment, the federal forecast – as issued at 11am on Tuesday – suggests many parts of the NWT could enjoy a little relief come Monday next week, when daytime highs could reach above -20C.
Inuvik, where temperatures are already comparatively cold, is expected to remain in the mid -20C range throughout the week – though again, Saturday could be a little colder overnight, at an expected -28C.
