Environment Canada predicts cold, sunny week, highs of -20
But just as skies cleared in the afternoon, temperatures were set to plunge from -11 to -23 overnight, -30 with the windchill. Environment Canada says temperatures are expected to hover around the -20 mark all day Monday, with the windchill around -33.
The long-range forecast calls for clear skies with daily highs around -20 until Friday, when it's expected to climb to -13. But the warmer temperatures will be accompanied by more snow.
