Taking a look at the boundary highlighted…it is moving south with showers developing further to the southwest. Will the interaction cause the convection to blow up? The CI product is not helpful as there is a thick cirrus shield overhead. This boundary is south of the main warm front where all the supercells are currently ongoing. Update to follow…

2209z…it looks like the outflow boundary is too far west to interact with echoes developing in Custer county. We will be looking for outflow boundaries from the supercells further north and see if we can get further development.
