Sure, but by definition a KU is an extreme event. Put all storms on a bell curve and we “define” KUs as those storms well above that +2SD threshold. Everything has to come together to reach those upper limits.
Edited my post more. I’ve said it before…I think of the systems and their “energy” as bodies in spacetime…the more potent or massive they are the more they bend the spacetime. Small bodies have less pull on massive bodies but can still affect their trajectory if they’re close enough.
Happens in a lot of systems
I mean it’s just different shortwave interactions…some tend to fuji/rotate around each other, sometimes it’s a kicker, sometimes it’s a phase which initially usually starts as fujiwara.
Ukie has the biggest shitstreak…it’s the most south. GFS clear it east and gets that more potent trailing s/w to dive enough south to fuji kick the system north a bit too. So my take is keep improving SE Canada and try to give it all more of a boot north. But the odds aren’t very good of anything substantial up here.
Idk..I think without a trailing s/w to boot this north there’s enough of a rotting block remaining to limit the northward extent of this before it’s mostly LBSW. It’s just curling up at too far south of a latitude otherwise.
Sometimes there’s model wide failures in depicting features. There’s still time for that given the mess out west. But yeah, every 6hrs of near status quo won’t get us there.
Goofus has a potent little s/w dive in late to help give the system another bump north toward SNE. The euro doesn’t have much of a trailing s/w and it just scoots E-ENE.
