That is slightly better than 10-1 here considering that there was rain at the beginning. Not surprised with the colder look aloft, as well as at the surface.
FWIW, which is probably not much, the mesos ARW, NSSL, and FV3 each respectively bring the low over the BM, just off the coast of NJ, and into NYC/CT, although if anyone can figure out where the nipple low is on the FV3, good luck.
UK was 5°F colder at the surface here at 18z Tuesday than its previous run, yet the Euro was 6°F warmer than 0z run. It was all about that nipple. The Euro had it and UK didn't. Same with the 925 thermals at 18z.
UK is 5 degrees colder here at 18z Tuesday vs the 0z run and the 925 temps are also colder. But then the low at 0z is west of last night's run, so the thermals then go higher. It will all come down to the position of that low between 18z and 0z. The UK and Canadian are the furthest west, pending the Euro.
