I trust their ability to diagnose daily departures...I don't blame them for not forecasting 30 degree departures at 6 days lead time...same reason you don't forecast 30" of snow 6 days out. Actual likely closer to climo.

lol … the Rev scratches his head at this statement

This mid and extended range doesn't scream historic warmth to me for anyone living N of roughly the Del Marva latitudes... not that anyone asked - 

There's too much confluence modeled to swing through southern Canada and the correction vector should be toward increasing sfc PP along the 50th parallel up there underneath...which means the obvious down to 40 N.

If for some reason we can tip toe through the next 4 to 10 days without getting a +PP in southern Ontario... we'd still need a well-mixed dry adiabatic atmosphere on long fetched continental flow, and so far, the warm sectors that - I feel - are over done because of the first point, are dirty anyway.

According to BOX climate page

BOS 39.3 (1913)

ORH 34.6 (1913)

PVD 38.6 (1932)

BDL 37.7 (1932)

If we're converting those into departures for 1981-2010, we'd need something like a +10 to +11 for the month.

Def doable...

BOS +13.4

ORH +11.0

BDL +12.1

...so far

Not with the huge flip to cold after the 20-22 period . AN sure and probably WAN, but nothing near records

Sure, double digit deperatures aren't exactly easy, but it's possible

I’ve heard this January 20th mentioned a lot.  What happens on the 20th?

Expand  

On or about that date is when the changes happening globally now over the Far East and Scandinavia translates to global atmospheric shuffle and we lose the PAC flow. 
Ask Scooter what he thinks about the last 10 days or so of Jan . See what he says

That was a surprisingly well articulated description, thanks.  Put me in the camp that these pattern changes take a bit longer than advertised, but eventually it’ll change.  The ebbs and flows of NE Winter.

Next weekends cutter on the 0z GFS would be a snow and ice storm for CNE/NNE, Just like all these other ones that look to shift east over time.

Expand  

Oof....for those 60F to powderfreak calls. GGEM was even starting to look precarious for SNE too but both medium range models first out of the gate tonight trended that way

Seems like most of these lakes cutters dampen out and end up further east as we get into the mid range, Yeah those 60F calls up in NNE are tough to achieve this time of year with clouds and low sun angle.
