Snow this weekend for Calgary

AFTERNOON UPDATE: Welp, here we go... getting ourselves toward ten or even 15 centimetres of snow is now a distinct possibility by Sunday as we ride these waves rolling free of the foothills. The majority of models show that east Calgary and west Calgary will be quite different, as snowfall totals go. There's a very good chance we wake up to a fresh coat of the white stuff on the ground tomorrow.

MORNING EDITION: Now that we’re less than 24 hours out, the forecast models – for the most part – are starting to reach a consensus. The answer is two to five centimetres. The timeline has moved up for the Calgary region, with snow beginning to fall late this evening – with a slight shot at flakes near the dinner-hour.

It then extends out to Sunday, with a moderate chance for flurries dying off near noon.

Saturday's snow will have a heavier impact in the foothills; snowfall warnings are in place in a band through Okotoks, K-Country and Canmore, and Crowsnest Pass/Pincher Creek, where 10 to 20 centimetres is more likely.

There remains a chance that Calgary sees up to 10 centimetres, but we're more than likely clinging to the periphery of the event; still, a commute Saturday afternoon from the east to the west end of Calgary could show stark contrasts in snow development.

A final major footnote for this snowfall; the temperature trend through Friday's low out to Sunday's high is in a range that produces watery snow; heavy, fat flakes are in order, and with them, we should expect a fair portion to melt as soon as they hit the ground.

Getting to 8 C today is certainly not spectacular compared to the rest of the month, but that’s still plenty warm enough to add a decent thermal layer to the road that inhibits snow growth (to a marginal degree).

Beyond, next week starts with a slight pop-up in temperatures… but don't hold your breath for those temps in the 20s.
