As expected, a snowfall warning first issued in central Alberta on Tuesday was further expanded to include all of southern Alberta by Thursday morning due to the synoptic setup.
A low pressure system situated over southern British Columbia and southern Alberta has stalled out and is dumping heavy, wet snow in a long-duration snowfall event.
(Snowfall warnings (white) issued by Environment and Climate Change Canada, cover all over southern Alberta on Thursday, Mar. 21, 2024. A long-duration snowfall event is expected to produce 10 to 30 centimetres of snow to the region.)
The counter-clockwise circulation around the low is creating isentropic lift – or upsloping – on the leeward side of the Rocky Mountains. A steady source of Pacific moisture continues to feed into the system producing a large region of dendritic growth (snow growth) in the atmosphere.
