Stolen from the mid-atlantic thread. Pole-reaching PNA ridge developing concurrently with TPV lobe centered east of Hudson Bay screams Manitoba mauler potential. Not sure why folks in the mid-atl thread are happy with this look. Polar jet is too fast to allow shortwaves to dig and subsequently tilt negatively south of new england
December 14-16 has looked nice on ensembles for several runs, as PNA ridge acts in conjunction with polar shortwaves diving south to create a miller b threat.
If not primary, secondary. Should erase possible subsidence from ORH band. Or, maybe when Worcester band begins to move away, the bands merge and we sit under 3" per hour snows all afternoon. Gonna be a fun one.
