Environment Canada has issued a snowfall warning as 10 to 25 centimetres is expected to fall on Tuesday.
As part of the citys seven-day snow and ice control plan, crews start to plow, salt and sand so-called Priority 1 routes (roads with traffic volumes exceeding 20,000 a day) such as Crowchild Trail and Macleod Trail once the snow has stopped falling.
A southward-moving cold front is bringing snow to much of southern Alberta. Areas at higher elevations could see upwards of 25 cm by Tuesday evening, while areas east of the foothills, including Calgary, will see closer to 10 cm.
The warning states that snowfall amounts will be “highly variable” along the unstable cold front.
There are snowfall warnings along the foothills stretching from Jasper National Park in the north to Crowsnest Pass and Cardston in the south.
A little over a week ago, much of southwestern Alberta was slammed by a near-record snowstorm, with more than 30 cm falling on Calgary.
Environment Canada meteorologist Dan Kulak said Calgarians shouldn’t be surprised by the quickly changing weather at this time of year.
“This is actually a seasonal pattern for October where we get the wild swings from 16 C to -3 C,” he said.
Snow, at times heavy, is expected to continue throughout the day in Calgary before tapering off tonight, when temperatures will plunge to -8 C. North winds gusting to 50 km/h will create a wind chill of -14 C.
Crews would continue focusing on salting and plowing high-volume routes such as Crowchild Trail and Glenmore Trail throughout the day.
Wednesday will be mostly sunny and cool, with a high of -1 C. Then a warming trend begins under sunny skies, with a forecast high of 9 C by Saturday.

A snowfall warning is in effect for Calgary. You can check all Alberta weather alerts here. You can also check Canada-wide weather alerts here.
Calgary got another early taste of winter after overnight rain turned into light snow — which gradually built up on roadways and made for a slippery morning commute — courtesy of "an active cold front that raced through much of Alberta," according to Environment Canada.
Conditions were slippery on many of the major roadways, especially in the northern and western parts of the city. Major delays were reported on the hill at Shaganappi Trail at John Laurie Boulevard northwest.

The Environment Canada forecast said the temperature in Calgary would drop slowly through the day to about –6 C as the snowfall intensified. The cold front also brought northerly wind gusts up to 50 km/hr.
In its snowfall warning for Calgary, Environment Canada said the city could get about 10 centimetres by the time the snow tapers off Tuesday night.
"As of Tuesday morning the cold front is located over southern Alberta and moving eastward into Saskatchewan," Environment Canada said on its website.
The province said highways west of Calgary are partly covered with snow and that visibility is poor.
The snowfall warnings extend all through southwestern Alberta. The Foothills and the mountain parks could get up to 25 cm by the time the snow ends Tuesday evening.
"Prepare for quickly changing and deteriorating travel conditions," Environment Canada said.
"Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow."
Calgary Transit says several bus routes are behind schedule, and routes 7, 8, 30, and 69 are on detour until further notice because of the snowfall.
The Calgary International Airport said the weather could impact flights on Tuesday. "Please check with your airlines on flight times and leave extra time to get to the airport. Safe travels," the airport said on its website.
