I saw that too. One nice thing we have, are cold temps in the conveyor belt. It may not pound after the heavy heavies leave, but decent temps still for snow flake production despite losing deep lift in the DGZ.
NAM also has what look to be weird G-wave features too? Check out the MSLP and then the 850 temps near the big lift at 700 mb. A warm pocket near the 700 lift.
But to what Will was saying, look at the curl on the 18z run vs flatter 12z. This is why at first I thought it might be better. Then I saw qpf and mslp and figured the difference was the convection.
Yeah I see that too, But I do think that is something to think about as this occludes and drives some convection at least to the east. It's not going to change what I have out, but I'm watching it.
I guess that's what bothers me. Is that real? If it is, that will leave it as a banded mess. If not, it will be a much stronger conveyor belt of moisture.
So in my mind something like a Reggie track is sort of what I envisioned when I look at the H5 stuff. A lot of the guidance shunted it east. I know why it did....but that was always sort of what I envisioned. Reggie caveats apply naturally this far out. That’s sort of a balance between lows feeding off of PVA and baroclinic processes in my mind, but I’m also not running complex atmospheric dynamics equations in my mind.
