I buy the two part jack area. First may be W- NW CT into nrn MA and SNH..somewhere there. Another may be near stronger low level forcing in ern MA, interior SE MA. Just a guess...can detail it later.
That’s a crusher from PHilly to NYC verbatim. It did make steps to improve I thought, but yeah...s/w shredder as it moves overhead on the gfs. Hopefully it’s wrong.
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.
