I remember -4 when the Ice Winter of 1994 swung into gear. There were rolling brownouts.

Yes, woke up to -13F and no power.  They said the power demand peaked over 6.5GW for the BGE area and mandatory rolling blackouts were needed to shed the excessive load.  All those chilly folks cranking up those 1500W heaters!  I still have the Pelonis disc furnace that I bought back in 1985 due to the big chill we had then.  I keep it in the shop, it makes a great load bank to test generators because it pulls 25+ amps for a few sec before the ceramic elements warm up.

Only thing worse back in the day when builders put in heat pumps everywhere and no TDRs (time delay relays) were used!  A quick interruption in power caused the compressors to stall when restarting against high head pressure.  Locked rotor amps on a four ton unit ran around 100A at 240V!  Multiply that by a few dozen houses fed off a single 7.2k overhead and a fuse pops and the whole neighborhood is out until a truck rolls to replace it.  Thank goodness for TDRs on modern systems and reclosers.  In today's electronic age folks would go nuts losing power for a few hours every time there was a little lightning.

Interested to see what this produces across our region, and the South as well. 

Baroclinic zone should hopefully spawn some interesting disturbances at lower latitudes. 

Also, liking the idea as well for squalls as mentioned by @MillvilleWx as the pattern progresses and during transition phases.

GFS, what are you smoking ?

GEFS is in that camp it seems. For the past 2-3 runs it's wanted to hold onto the PV being a fair bit west and pumping up the ridge to the east. Even then it's not as extreme as the op, and quite frankly a blend between the GEFS and the EPS would look pretty sweet wrt the overrunning event. GEFS is on the wet/warmer end (still some nice hits in there), EPS is on the colder and drier side.

ENDLESS Opportunities with the target zone being the Mid Atlantic IMO , don't focus on the exact placements, or that this is the GFS,  simply look at the feed of cold and disturbances. 

Impossible to say which ones might blossom into a bigger event at this time, but there will be opportunities,  and some of those may be cold powder as well, with snow on snow.

True,  lets see how things evolve in the coming days.

The Vincent van Gogh model view is a dandy!  Fun times ahead for sure!
