Where I am, I'm all in on under amped. You guys can do better with amped systems.

Yes. If he’s already mentioning the possibility there is a side of legit with this.

We're walking such a fine line. We need a phase, so we need some dig here it looks like. The energy can't be left back for a good hit. So you hope for eventually amplification. But how much? Too much and RDU is out, but some 77 corridor may work. Too little 77 may be left out. Pins and needles.

A series of impulses will carve out and reinforce a broad mean trough over the central and eastern states during the extended period while the upper ridge amplifies offshore the West Coast. The leading shortwave will track over the Great Lakes region into the Northeast by Thursday with one behind it digging into the South Friday and then pulling offshore the Mid-Atlantic/Southeast region Saturday. This pattern will be conducive for precipitation to spread across the higher terrain of the Northern and Central Rockies through Friday and precipitation to span from Texas/western Gulf Coast, Deep South, Southeast to the Mid-Atlantic and push eastward beyond the weekend into next early next week.
Previously, it was noted that there is significant forecast spread and run to run uncertainty with this latter feature and associated mid-winter weather focus with frontal wave/coastal low genesis. The 06Z/12Z guidance continues to have notable spread on the placement/track of the secondary shortwave feature. In turn, the QPF placement varies significantly as well, especially across the Gulf states, Southeast and Southern Appalachia. To combat these differences, a general blend of the GFS/GEFS mean/CMC/ECWMF/EC ensemble means were used through all time periods. This provide a middle ground approach and helped maintain continuity from the previous forecast cycle.
...As the Arctic blast reaches the southern tier states a wavy cold front will encounter Gulf moisture to fuel an emerging area of precipitation up from the South/Southeast. This pattern will be favorable for an enhanced swath of overrunning snow/ice on the northern periphery of activity later in the week. This wave may develop into a robust coastal low/winter storm that tracks up the East Coast.

Yeah this pretty much sums it up. The intriguing aspect of this setup continues to be the sneaky arctic boundary draped off the coast and back SW into the Gulf with cold high pressure to the NW.

The CAE NWS says yes, and was saying yes yesterday as well even though the discussion IIRC was kinda more like "it's too early to tell"

Not IMBY but a pretty rare and gutsy call by NWS KGNV/KJAX in their afternoon update this far out ... regarding very late this week ...
Friday through the weekend, A strong center of high pressure will
build in behind the front from the midwest filtering in another
chilly airmass that will deliver well below normal temperatures
to end the week with a potential for light freezing rain and snow
flurries over inland SE GA areas as suggested by the ECMWF which
keep precipitation over the area as temperatures fall below
freezing north of I-10 late Friday evening into Saturday morning
while GFS pulls all the precip off the coast before temperatures
fall below freezing Friday night.

I’m flying out of CLT tomorrow (hopefully) so I expect you’ll have this thing heading toward 85 & 40 by the time I get home next weekend!
those temps look even colder then today’s event
