There is definitely a change coming, after Friday where the low dipped to -23.4°C in the morning, it looks like the temperature is going to slowly going to go up and up. It might not go down again till sometime on Sunday (maybe even Sunday evening).
And it's not just the short term that sees higher temperatures, with some forecasted highs of 6 in middle of next week.
After that, the medium range forecasts have it staying either at or a bit above average into mid-March. Thus I'll be bold and predict that today is going to be the coldest day we see until the fall.
