Winter storm and snowfall warnings cover all of southern Manitoba as a major winter storm approaches. Light snowfall has already begun in southwestern and western Manitoba. However, the real heavy snowfall is expected to move in later this evening and especially overnight. This snow is expected to last through much of Saturday. Upsloping winds will also offer enhanced snowfall amounts for the western RRV and especially into the Duck and Riding Mountains.
Snowfall is expected to continue into Saturday night with lingering periods of snow expected Sunday. Lingering fluries are still possible Sunday night, but beyond that things look to improve.
Totals for this system are expected to be in the 20 to 30 cm range for many areas, with localized amounts between 30 and 45 cm possible over the upsloping regions I mentioned above. A few 30+ cm amounts are still possible elsewhere however.
The precipitation is expected to mix in with rain, freezing rain or ice pellets for the southern RRV and southeastern Manitoba as the warm part of the system just grazes us. Great uncertainty still lies on how far west this warm sector will go, therefore at this point it is hard to say if Winnipeg will be getting some of this mixed precipitation.
Winds are expected to be strong unfortunately, but thankfully not to an exceptional level; sustained between 30 and 40 km/h with gusts of 50 km/h. Blowing snow will be an issue as a result.
As far as records are concerned, it will be difficult for Winnipeg to break the daily snowfall record tomorrow, considering it lies at 31 cm back in 1919.
