Frost advisory issued for much of the province, including Calgary

Flurries dusted parts of Calgary and blanketed the Rockies on Labour Day Monday in an overnight about-face from weekend highs that saw temperatures reach 29 C.

On Sept. 4, Environment Canada forecasted that Albertans could experience an abrupt transition to autumn over the holiday weekend because of a low pressure system moving through southeastern parts of the province on Saturday night.

On Labour Day, Environment Canada also issued frost advisories for much of the province, including Calgary. Frost advisories are expected when temperatures are expected to reach freezing during growing seasons.

Up to five centimetres of snow was forecasted for higher elevations in the Foothills and up to 10 centimetres on east-facing slopes.

On Monday morning, Sunshine Village Ski Resort shared photos of the grounds covered with snow and blanketed by fog.

Meanwhile, Calgarians shared videos and photos on social media of snow dusting front lawns and decks.

Environment Canada said there was a chance of seeing mixed precipitation in Calgary, though the forecasted snowfall was expected to remain in and near the mountain parks.

Morning lows in the city hovered around 2 C, while the average high for the September holiday in Calgary is 18 C. 

The highest snowfall on record for Labour Day in Calgary was 11.4 centimetres in 1962.
