June 22, 2007 |  Brief Rotating Storm and Funnel near Black Hills

There was much weaker forcing today along the periphery of an upper ridge, but there would be just enough upslope flow that around 1300 MDT convection did manage to fire along the Black Hills.  All the storms were rather high based with marginal structure.  The first storm never really exhibited any rotation visually, although one farther north did culminate with a two minute funnel.  Given limited bulk shear along the upper ridge, endurance was not in the cards for any of these cells.  I aborted this area in favor of storms in southwest ND near Dickinson along a stalling cold front, but naturally these died as I arrived in Bowman.  Since I was not that far from home and considering I'd likely be chasing in Canada the following day, I headed home for the night.  On the way I couldn't resist stopping for some quick photos at the scenic Theodore Roosevelt National Park, but needed to keep moving as I was still three hours from home.  I would have made it back before midnight, but two annoying construction zones at dark with 20 mph pilot cars delayed me a solid hour!
