Last week we saw a Colorado low push through southern Manitoba, bringing with it some significant amounts of rain, snow, ice pellets and freezing rain. This week we need to keep an eye on an Alberta clipper forecast to develop on Wednesday and push through southern regions on Thursday and Friday.

The models have been fairly consistent forecasting this Alberta clipper system. Over the last couple of days most models have been leaning toward a fairly strong system. Just like last week’s storm, the question is, how much warm air will work into the system and thus how much snow or rain will we see? It is going to be a close call once again, but with colder air in place ahead of the system, it looks like we will see more snow than rain. Overall we could see snowfall amounts in the five-to 15-cm range with an outside chance of seeing upward of 25 cm.

Once this system pushes by, we will see a strong northerly flow behind it, which will usher in some winter-like temperatures. Fortunately these colder temperatures don’t look like they will stick around long, as a strong low is expected to track across the far north. This low will be too far north to affect us directly, but southerly winds ahead of this system will help boost our temperatures back toward the 0C mark by early next week.

Once this northern low pushes by, the models hint at an outbreak of arctic air, which could usher in the coldest air of the season by the second half of next week.

Usual temperature range for this period: Highs: -8 to 5C. Lows: -17 to -4C.

Probability of precipitation falling as snow: 90 per cent.
