Alberta faces rare summer snow and another soaking as temperatures drop

Unseasonably cold weather will bring mountain snow, heavy rain and icy conditions to parts of the province.

A powerful shift in Alberta’s summer weather is underway, with a developing trough bringing plunging temperatures, heavy rain and even mid-summer snowfall to some areas.

While the workweek begins wet for many in the Prairies, conditions will cool sharply by Tuesday, with temperatures expected to fall 10 to 15 degrees below seasonal in central and southern Alberta.

Summer snow sneaks into Alberta’s mountains

That cooldown will be sufficient to start accumulating snow in the Rockies, particularly in elevations above 2,000 metres. 

The Jasper region and Icefields Parkway are likely targets, with snow forecast just 60 km west of Calgary in the higher elevations near Banff.

Travellers and outdoor workers in these areas should prepare for locally slippery conditions, with a reminder that summer snow in Alberta’s mountains, while uncommon, is not unheard of.

Further south, steady precipitation is expected to drench Alberta’s lower elevations.
