Can a willing met explain the basic physics principles behind secondary LP development? And what that might mean for this situation, what with the H5 track so far west? Eager minds want to know
does closing off the mid/lower levels prevent, for lack of a better term, upper level energy (?) flowing northward unencumbered with the shape of the jet? I'd guess that it's meaningful in terms of wind fields and how different levels of the column change temperature. Am I kind of understanding? I still don't get exactly what would cause closing off to happen.
GFS ticks east, GEFS tick west. Just isolating trends in the american models, we appear to be narrowing the goal posts between and outer-cape track and a coastal plain hugger.
Oh well. Pattern is long. I remember how painful the first storm of March 2018 was because I was delusionally hopeful for evaporative cooling. A few days later, we got a foot and a half, bookended by two half-footers.
I mean, I'd be lying to myself if the GEFS doesn't keep me interested in the threat, but as of now, it's a far eastern outlier. Plus, doesn't GFS/GEFS have a progressive bias?
Yeah, but even so hopefully we get the decaying band at some point. Apparently thats how these H7 goodies go, they can linger on for long past the system passes, or so I've heard
