stormdoctor > This amazingly low wall cloud repeatedly generated tornado warnings.  Here it is seen just north of Bison, KS, on May 24, 2008.  While some chasers were able to confirm that the wall cloud caused dust whirls (and thus became tornadic), this was not something I personally could confirm.  Nevertheless, it was easily the closest I've seen a wall cloud graze the ground.  Interestingly, the RFD on this cell generated what appeared to be a gustnado along its outflow.  Many reported this as a tornado.

stormdoctor > This was an example of an outflow-dominant storm (far background and right) enhancing lift of an updraft (foreground, left).  This eventually caused the updraft to intensify before the storm collapsed and became outflow dominant for good.
stormdoctor > You'll have to look at this photo carefully.  At the bottom left and the bottom right are two features associated with this gust front called gustnadoes.  They are often mistaken as tornadoes, and these were as well prompting tornado sirens to sound in Akron which is just to the left (outside the frame).  They are in fact not at all tornadoes, and in fact form on the outflow of storms.  Brief rotation under the rapidly expanding shelf cloud results in these "dust whirls".  The real danger actually lies just behind the gustnadoes where straight line winds >70mph were clocked.  I liked the dirt tracks leading off into the storm.
