:?: Very interesting pix. Its hard to say. It definatly has the classic shape of a cone funnel but does not appear to have a wall cloud. It may very well be a wall cloud. It will be interesting to see what others have to say.
Again its hard to say since this is a still image, however, another image of the same storm and suspect area is posted for 2 minutes later. The latter one shows a pronounced RFD slot cutting in from the left of the feature (funnel?) compared to the first. This is significant rotation at least at the mesocyclone level. The funnel in question can simply be a tag of scud along the RFD gust front if it is not rotating.
