March 19, 2011 — Sunday marks the vernal equinox -- the official start of spring -- but with 10 to 20 cm of snow expected for parts of the Prairies, it's going to look and feel more like winter.

A low pressure system developing in the lee of the Rockies will start to produce snow over southern Alberta by Saturday afternoon.

Calgary, Lethbridge and Medicine Hat could all see 10 to 20 cm of snow by the end of the day Sunday.

Temperatures will be on the cool side in the wake of the storm, slowing the melting trend that has put officials in at least one southern Alberta community on high flood alert.

A strong easterly flow means the system will affect a long swath of the southern Prairies throughout the day on Sunday, says Dayna Vettese, a meteorologist at The Weather Network.

“Most of the snow will be through southern Alberta and Saskatchewan, but we could see some mixing in eastern Saskatchewan.”

Warmer temperatures mean the system will bring mostly rain to southern Manitoba, including Winnipeg.

The precipitation should clear out by Sunday night.
