It will be a cold night tonight as we drop to the high to mid minus teens. Tomorrow will be downright chilly for this time of year, being some 7 to 9 degrees below normal. Highs around -7°C to -9°C are expected. Another cold night tomorrow night with lows in the mid minus teens.
It could be worse however. Given how cold the airmass that is moving in is, if we had snow on the ground we would be talking about lows in the minus 20's. Thankfully we don't have a snow pack on the ground. The effect of a snow pack on the ground is significant. In Saskatoon, which seems to already be in full winter, saw a low around -22°C this morning, and is expected to be just as cold tomorrow. Highs in the mid minus teens are expected there today. Snow has been on the ground there for several days now.
Temperatures rebound on Tuesday back to more normal values, with a high around -1 to -2°C expected. Generally seasonal to above seasonal temperatures are expected through the remainder of the week. No major snowstorms expected this week.
Here's a collection of webcam images from the Prairie's biggest cities this morning, just to compare how winter has been progressing so far. As you can see, we've been fairly lucky in Winnipeg so far.
