11:30am update from Valentine, NE | I'm pretty much committing myself to the northern target. I like the
look of the visible satellite with a lot of clearing in the
central/northern South Dakota area. 60s dewpoints will spread north
through the day. There is north-south baroclinic zone that will
develop, thanks to prolonged stratus farther west toward western South
Dakota. This will enhance local lifting due to frontogenesis... with
2500 to 3000 J/kg CAPE developing to the east over a large area.
Vertical shear is not spectacular this far north, but directional
shear will be adequate for nice storm organization and supercells.
