That being said, my prediction for southern Manitoba is as follows:
|Snowfall totals from midnight tonight to Monday morning|
I expect about 2-5 cm in Winnipeg, although that is a ball-park estimate. We may get even more than that if more snow develops along the inverted trough than expected, which is what these troughs are notorious for. Perhaps less if the trough doesn't produce much, which is what I am leaning towards.
What I'm pretty certain is that much of the real system snow will stay to our south and east, in a narrow band grazing south eastern Manitoba. That is why areas just to our south east will likely see higher accumulations of 5-10 cm.
It's a tough forecast tomorrow though, as it could be a situation of 5 cm in one location, and not even a flake 50 km away. Then again, the inverted trough could produce more snow than expected. We're just going to have wait for tomorrow morning to see just how things really will play out.
