I’m just not seeing anything that screams “major” ice storm. There is retreating HP, the timing will have to be perfect with the transient HP to have any frozen, the antecedent cold air is marginal, and this all relies on the system staying relatively weak and not routing the cold air before a wedge can get established. Long story short, this looks like in-situ CAD and some ice but I really doubt this is a major ice storm, at least from the setup I’m seeing
