Southern lead s/w doing the dirty work, Allowing the trailer to drop in behind. Let's get this baby to close off and bowling ball S of us. Would make us all happy.
My hope is there isn't one, but my gut says there will based upon what I see in the upper/mid-levels. There looks to be a pretty solid front band that pushes inland from the initial storm intensifying S of us. That band will rot inland and another will develop along the southern areas as the low starts pushing eastward. This would be over Eastern areas.
My eyes will be looking at the 700mb heights. Need to watch where that subsidence zone is. You can see the differences in the models in where they place the snow bands. NAM I fell is too far N. The GFS is still too far S. The Ukie/RGEM/GGEM/Euro(lesser extent) are sort of in the middle. They bring that subsidence zone over the 495 belt W and N of BOS. Hopefully they are wrong and we see a more widespread precip shield with minimal breaks.
Time to start focusing on the smaller details as the large synoptic features are there. Where is there subsidence/dryslot issues. Where will there be enhanced snow areas, fronto and mid-level banding. Also, time to hand the baton off to the OP runs.
