Well, since I'm originally from Winnipeg, my advice to anyone wanting to experience wind chill would be to stand at the corner of Portage and Main.
... wearing a Hawaiian shirt, shorts, and flip-flops. Underwear optional.

Yep, good ol' Winterpeg has a reputation, even among Canadians. Seems like a perfect location for extreme adventure tourism. It's all in the marketing.
Back to the OP: there may well be a better way of communicating the effects of wind chill to the general public. Up here, when there is extreme wind chill, the news forecasters often add the tag "... that means exposed flesh will freeze in less than one minute." Kinda drives home the point.
