Well, then let's jump right ahead to Dec 1st, which just happens to be the latest possible time in the GFS prior to truncation.  The gradient that we expect to start the month with is there, and it is definitely further south.  Quick peek at the post 192-hr output is too (erroneously) progressive to glean anything useful.

Can you define furnace in terms of what you expect for temps on those days please

 

 

I expect at least a couple days in the 50s after 12/2-12/3 or so. No cold air to speak of even for a few days past that...probably some days in the mid to upper 40s as well.

 

12/10 or so could finally reload.

Snowmaking Pony-Os aren't stoked on the long range. Looks pretty putrid on both GEFS and ECM ENS.

Just for giggles, the end of the GFS run looks pretty darn warm for December 10th. Total clown range but would be impressive (not in a good way) to have the entire US with above freezing 850s on 12/10.

Talk about a blowtorch. Honestly though I wouldn't be surprised given the state of the MJO at that time. You would think the pattern would change right after this period. No need for worry.

Weeklies begin to reload the Aleutian low and PNA out west during week 3 into week 4. The fact that the signal gets better week 4 is good considering week 4 sometimes seems like a muted version of week 3.

Seems in line with the MJO forecast.
