"As colder air wraps into this system the rain will change to wet snow tonight and continue to snow through the day on Friday," the alert states.

"Generally, 10 to 20 cm of snow can be expected, however with temperatures near the freezing mark, there will be some melting of the falling snow."

Visibility may be suddenly reduced at times in heavy snow, Environment Canada said, adding that freezing rain is possible in the Churchill area Thursday night and into Friday morning.
