Those models deserve a good flogging!!
"GFS, I don't want to hear your lame excuses about fast flow, destructive wave interference or Hadley Cells. Go sit in the corner! We're replacing you this cycle with the JMA."
On the GGEM, the PV shifted well north. But the system then went from closed to a flatter, open wave. Can't figure out why -- it almost looks like the PV diving further south spiked the eastern edge of the ridge, which amplified the storm.
Seems like it hung back a little the last day or so, and was more robust and north. But then another vortex dropped in from Maine to squash and starve it.
Can't recall such a long stretch of winter when there's no strong systems really anywhere outside the northwest. Even the long-range globals have given up inventing bombs. It's like the atmosphere is starved or something.
Western Mass is a solid upslope location following departing lows or from upper-air impulses. With the weekend system long gone, are this week's very persistent snows because of the juicier Pac air carried on west winds?
