The snow has begun over the city already this evening, and will continue after midnight before ending overnight. Not a lot of snow, perhaps 1 or 2 cm. Wind is fairly light, so blowing snow wont be a big problem. Temperatures will slowly rise tonight, and we should be waking up in the morning near -10 or -11 C. It will be a warmer day tomorrow with high near -7 or -8 C. Cloudy skies are expected though, and that is true Sunday as well.
Sunday will be much milder as a clipper system moves through. Some flurries are expected around the city during the day, perhaps a cm. Although, the bulk of the snow will fall in the Interlake with 5-10 cm possible there. Highs in the city should be near -3 C Sunday. A brisk south wind of 30/50 km/h will make it feel colder than that -3 C though.
Behind that system Sunday, frigid arctic air will wrap behind the system, and descend Monday. Next week will be frigid with the coldest air we've seen so far this winter. We will wake up Monday in the mid minus teens, although WNW winds of 30/50 km/h will make it feel much colder, similar to last Wednesday. Temperatures wont rise much at all Monday.
Beyond Monday, the rest of the next week looks frigid with highs barely over -20 C, as well as the possibility for our first -30 C readings since last February.
Even farther in the future, models have been trending towards a warmer end to January, although that could change...
Stay tuned for updates.. =)
