Snow was repelling off your face as the Impervious Charm was working since its original cast. The wind was simply making it hard for you to move forward, forcing itself against you and blowing snow about. As for the path you were making, it was steadily filling in with snow. But the wind here, contrary to what you may think, is not meant to be an inconvenience. It is meant to provide you with a clue should certain characteristics be observed and interpreted.

A stream of bubbles were conjured from the tip of you wand and were instantly carried with the wind, heading southward. Your heightened senses can see the multi-coloured spheres freezing and then dropping into the snow with soft thuds.

Perhaps a different tactic should be used. One that involved a little attention to detail. The wind coming from the north was still present. Is it possible you could predict something based on its sudden change in direction? You also need to make a decision: go against the wind or go with it?
