I waited around Devils Lake most of the late afternoon until finally some agitated Cu popped to my SW.  One Cb materialized from this and began tracking NE.  It quickly developed inflow bands that fed into a nice RFB that became circular with time.  Per the RUC, instability and shear values up here were quite supportive for tornadoes (e.g. STP of 3), but this LP supercell didn't last much longer than 90min total as it never made a solid turn to the east along the outflow boundary.  As a result of its continued NE motion, it crossed the outflow axis, hit the shallow stable bubble and began dying a typical LP death (see sfc analysis below).  New convection had already popped further east by this time, but it too couldn't make a turn to save itself.

I did see a pair of probable supercells erupt further north in Manitoba before sunset, but they weren't worth making a border crossing to chase so late in the day.  Overall, the LP supercell did present some nice photo ops as shown below.  Also, this is the farthest north I've ever chased to date...I stopped just 8mi south of the Manitoba border, eh!
