Appears to be -12C to -23C over this weekend, so quite a change from the +6C yesterday ?

Might have been a fluke or a dodgy website, so went to the canadian government one

https://weather.gc.ca/city/pages/nu-10_metric_e.html which seem to be similar.

No idea how cold it should be, but some of the russian cities in the deep frozen wastes seem to get much colder with -50C being common, suspect the water underneath the arctic shields it a tad ?
