Of moderate interest is a system coming through Thursday night/Friday. Some differences of opinion about this one again. However, I don't have much disagreement with map below at this point. I do think Environment Canada is too warm again for their forcast from Friday on:
Friday: Showers. Low minus 1. High plus 5.
Saturday: A mix of sun and cloud. Low minus 8. High minus 2.
Sunday: A mix of sun and cloud. Low minus 11. High minus 3.
Look for these forecast temperatures to come down over the next few days.
