I’m still trying to figure out what 8s allowing that subtle lifting out to get this further north. All I can see is some larger subtle downstream troughing that allows heights behind to lift a little more.
Throw up the GFS 500mb North Atlantic view on Tropical Tidbits and you can see what I am referring to, our exiting storm takes its time, meanwhile our next storm comes in like a heat sealing missile, only to hit a brick wall.
This storm will only appear slow because it’s slamming into the system that’s exiting us now. I don’t see this as a maturing coastal as it hits our latitude. That’ll be further SW of us in the mid Atlantic. Doesn’t mean we can’t have a sizable storm, I just don’t see a WCB combined with a CCB to produce those prolific totals.
Nope. Shitstreak halts this bowling ball in its tracks and the main s/w than has to undercut it while the backside energy has no where to go but carve itself underneath the main s/w, which than elongates the entire system.
