These runs are choking off (occluding) the developing mid level low approaching CT pretty quickly so the best dynamics shift to the triple point well east.
Nammy keeps the conveyors going
Accums can be variable this time of year too. Where the sun is hitting this time of year there’s a little bit of “stored” heat in the ground versus the shade. So even if you’re pounding at 32-33° there can be a little melt compaction at the bottom. Then you have the varying surface albedos which can come into effect early on if the sun can “see through” light accums to the sfc or if the rates lessen or clouds thin.
Relatively meh dynamically out east after the Ronnie Coleman IVT for the Catskills and WNE. I had more hope for up here given the track just north of PVC, but no dice.
But that first low at 12z helped back the flow a bit and keep 925 from torching too much. It doesn’t matter with a track like this…there’s enough forcing and dynamics to overcome it. Just don’t let it get too far east.
