Note the steady increase in wind speed and the unchanging wind direction. Meanwhile, Thredbo AWS (not far away and exposed) has been registering very light breezes (0-10km/h) over the same period.

What's going on here? Is the Cabramurra AWS situated on the side of a large hill above a valley? i.e. could there be (katabatic) winds running downslope as a temperature inversion sets up?

I was at Cabra once when it went from nothing to over a foot settled overnight. Uni cross country club. We made a 'snowman'

in the footy pitch.
But conditions were matched in Selwin which was not far away.
