EF0 Snownado, Gustnado, or Rotating Virga? 4/8/09

It's either a very weak snownado, gustnado, or a spinning chunk of virga. Look for it at 170500.

It seems to start on top of the snow covered mountain (Snownado?), so this rules out thermal evolution (could be terrain induced upslope updraft) and then move my way. It also appears to be attached to a minor front, so that's the gustnado guess. Finally, when it overhead, I was getting "whipping winds" from several directions, but no sign of severe weather when I looked outside (in the wrong direction at the time).

It was only after I compiled the stills into the timelapse, did I see this. And due to the winds, as witnessed by the moving vegitation, it obviously had ground contact, although no visible funnel was reaching the ground at that time.

So what do you think it is? Post comments please.

P.S. Weather data is from KCPR which is 5 miles away.

Best Watched in HQ folks. Clock is too fine of detail for Low-Res.
