What year was the big snow storm in Edmonton?

Answer 1

1989, if you're referring to that one. Here is an excerpt from Environment Canada:

January 29-31, 1989: Alberta was experiencing a mild period during the latter part of January up until a particularly vicious cold front from the Yukon dropped temperatures from plus 2 C to -12 in the span of an hour, as it charged through Edmonton during morning rushhour on the 30th. Rain rapidly changed to heavy snow and the mercury fell to the -25 range and was still falling at noon. By that time the front had surged through Calgary, and by late afternoon the entire province was in the grips of a blizzard. The Edmonton area received the most snow, around 35 cm, an all-time January record. Portions of the province south and east of Red Deer were spared the snow, but still had to endure the bitterly cold winds. The effects of the storm lingered for days. Temperatures were in the minus 30's. In the Edmonton area alone, seven deaths were directly attributed to the storm's fury.

On the next day, some of my friends were not able to get out their doors. Some even had to jump out of the window into the snow and dug their doorway out. There was no bus service available and the University of Alberta was closed for the day. The interesting thing was that the elementary schools remained open. That made a lot of parents calling the radio station to complain.
