CI Low but Severe CI High?

Today's CI products seemed to pinpoint the initial convection for the day the best so far this week across SE Wyoming. However, CI was highlighting convection potential at 30-40% but Severe CI was highlighting areas 80-90% off convective clouds off Snowy Range and Laramie Mountains. Why would it only be a low chance of convective initiation but a higher chance of severe convection?

Update #1: Severe Warnings were issued for these storms around 2030Z
Update #2: No severe reports across WY were in as of 0045Z
