It may seem nice out there with the sunshine right now, but it could be a different story this evening. In addition, winds will be quite strong this afternoon with gusts to 70 km/h.
It will be mild with highs approaching 0°C, especially this evening. A low pressure moving into central Manitoba, which will be giving central and northern Manitoba another blast of snowfall (10 to 20 cm), will also bring southern Manitoba some messy conditions this evening. Freezing rain is possible in all of southern Manitoba, therefore freezing rain warnings have been issued by Environment Canada for all of southern Manitoba except the Melita and Virden regions. Some areas may see a mm or two, while some may get just a couple sprinkles. It is hard to say right now since the area of precipitation hasn't formed yet. In addition, it is possible that the precipitation may fall as ice pellets instead.
Nonotheless, it will likely be a messy evening.
Cold weather will dominate the rest of the week into the weekend.
UPDATE: Here's a good article about the snowfall in northern Manitoba early this week. Up to 90 cm of snow fell in the Norway House-Island Lakes region in 24 hours, possibly making it the heaviest 24 hour snowfall on record in Manitoba. It's hard to confirm this due to the fact that the snowfall amounts are not official.
