THU 07 JUN 2018Two main targets at play today - southeast Wyoming close to the warm front / dry line intersection, or northeast Wyoming into southeast Montana where the warm front was likely to interact with a couple of outflow boundaries. Either way, shear was a little marginal for organised storms / supercells, perhaps slightly better in northeast Wyoming / southeast Montana.
