Snowfall rates intensify and spreads from the foothills, and moves across the QE2 and regions farther east.

Impacts will be felt near Calgary, possibly in Red Deer, depending on how far north the storm lifts, and possibly south of Calgary, depending on if the track remains south.
There is a risk for 10-20+cm of snowfall along Alberta’s busiest commuting corridor.
The snowfall will last through Thursday, lifting by the evening.

Folks should brace for winter travel, with a very difficult and slow commute Thursday morning and onwards. Impacts include all highways in and near Red Deer, Calgary and south, including QE2 and the Trans-Canada.
However, there is plenty of uncertainty on where the heaviest amount of snow will fall at this time, depending on the location of the developing low and how far north it tracks.
