Climbing the coast doesn’t create negative tilt, we just need the energy to dig a bit more and consolidate, which gives us a better chance at a negatively tilted storm. Right now it’s weak and strung out. It’s shooting out to sea at the moment because it has no room to lift north because of the 50/50 low blocking it near Nova Scotia. The trend during 12z is to scoot that 50/50 low further east, letting the storm have more room to climb and high pressure feeding cold air down the spine of the apps. All positive steps but a slightly more amplified storm would help a bit.
