Unwelcome news for people in Alberta: Parts of the province may be in for as much as 10 cm of snow on Monday. Here are four things to know. 

1. What’s causing the snow? 

Temperatures have been at or above seasonal for the past few days in Alberta but change is on the way.

The combination of a low pressure system tracking south, combined with a strong arctic air mass in behind will allow cool, below-seasonal temperatures to flood into southern parts of the Prairies and with this comes the threat for snow. 

2. Timing/duration of the system 


Showers will move into Edmonton and surrounding areas Sunday afternoon. As the system continues to push south, the probability for snow and mixing increases.

Monday Morning: 

“Monday morning, mixing looks to be staying tight along the foothills and northwest of Edmonton,” says Weather Network meteorologist Kelly Sonnengburg. “Edmonton and Calgary should only see showers.” 

Monday Afternoon: 

Throughout the day Monday, temperatures will drastically decrease to low single digits.

Temperatures will be the big deciding factor for when areas could see the transition to snow or mixing. 

“Ground temperatures will be warm from the previous day, so snow will have a difficult time sticking to warm pavement,” says Tyler Hamilton, another meteorologist at The Weather Network. “Accumulation of a few slushy centimetres on grassy areas is possible.”

Monday Evening: 

By Monday evening, most of the precipitation should be south of Edmonton. With cooler temperatures, there’s the chance for seeing more widespread mixing along the foothills, primarily west of the QE2

The evening commute will likely be impacted by this for Calgary and surrounding areas.

“The higher elevation coupled with a burst of heavy precipitation for an hour or two could put down accumulating snow on grassy surfaces, and possibly enough to create some slush on roads,” cautions Weather Network Chief Meteorologist Chris Scott. 

Overnight Monday into Tuesday: 

Temperatures will be riding right around the freezing mark, so any precipitation that occurs could be a mix of rain and snow. 

Tuesday Morning: 

Mixing is still possible along the foothills including Calgary since temperatures are still hovering near zero. 

With warmer ground temperatures, any snow that falls will likely melt on impact. Any accumulation that does form will be minimal and slushy. 

Most roadways will remain clear due to the warm ground temps, but grassy areas could see marginal accumulation.


Wednesday poses a similar threat with a rain/snow mix along the foothills including Calgary. 

3. Snowfall Forecast (Monday through Tuesday) 

Through the mountains and northern parts of the foothills up to 10 cm of snow is possible. Areas south and east of the foothills will only see less than 5 cm. 

It is important to stress that accumulations are dependent on ground surface
