Seasonal temperatures will be in place for Winnipeg & the Red River Valley for the start of the week as a continued weak southerly flow keeps the Arctic air locked up to our north.
Temperatures will sit near -10°C today through Winnipeg & the RRV, perhaps climbing up to -9 or -8°C briefly. We’ll see light snow through much of the morning with a chance for it to redevelop this evening for a few hours. Accumulations will sit around 2-4cm from this very light, fluffy snow, but it will likely have significant impact on roadways. Combined with the warmer temperatures, fog, and patchy freezing drizzle, some roads in Winnipeg and some provincial highways are already quite icy. As this light, fluffy snow is driven on, it tends to compact to a thin layer of ice; this will likely make it so that some highways, including the Perimeter Highway, side-streets and intersections are quite slippery by the evening commute. Be sure to leave yourself some extra time if you need to drive this evening.
Temperatures will remain fairly steady tonight or even climb a degree or two and another push of warmer air moves in. Once again we’ll likely see dense fog patches and patchy freezing drizzle redevelop tonight as this warm air advances towards the RRV.
Tomorrow, temperatures will climb to about -5°C with scattered flurries through the RRV. Winds will remain light, so it will be another great day to get outside. Some light snow will move through Winnipeg & the RRV tomorrow evening/night as a weak disturbance passes to our south. We’ll get another 1-2cm of snow as temperatures drop back towards -10°C.
Wednesday looks to be almost a carbon copy of today, with some light snow and highs around -9°C. The rest of the week is a little more uncertain; models all hint that the upper-level flow pattern will begin to break down, but how quickly that will happen is uncertain still. While the next few days will almost certainly be cloudy, we’ll probably see the sun start to make an appearance later in the week, if not having the clouds completely clear out. We’ll have more details on the second half of the week on Wednesday.
