The next few days will feature a roller coaster ride in temperatures as well as many opportunities for snow.
After a low of -27.4°C at Winnipeg airport this morning, temperatures are expected to skyrocket this morning, reaching or even exceeding the freezing mark by afternoon. Right now I don't have any stats on the biggest single-day jumps in temperature, but I may try to gather some for the January summary. Surprisingly, we may even come close to a record high today. Old record is just 2.2°C in 1973.
Snow will begin this morning and continue until this afternoon. 4-8 cm is expected with this initial wave of snow. Winds will strengthen to south 40 km/h this morning, giving blowing snow and trecherous driving conditions on highways. A brief period of ice pellets or freezing rain is possible this afternoon as the warmer air moves in.
More snow is expected this evening and tonight, but more on and off in nature, with an additional 1-3 cm possible. Winds from the north-northwest at 50 gusting to 70 km/h will create awful conditions on highways. In addition, plummeting temperatures tomorrow morning will make highways extremely slick. Avoid unnecessary travel tomorrow morning. Winds will weaken slightly tomorrow afternoon and become light tomorrow night. After a high near or above zero today, temperatures tomorrow night will plummet into the -20's.
We go back up the roller coaster on Friday as another clipper system moves in. Snow is expected to begin in the afternoon and continue in the evening. 2-5 cm is possible. This system does not look as intense as today's. Highs in the mid to high minus single digits are expected.
At this point, another clipper system is possible for Sunday, but it is unclear right now what impact that will have on Winnipeg.
