It's only 9-10 Days away, KFOR is already showing lows in the mid-20s in OKC around December 5th as well

Iceresistance seems like the GEFS is faster with the arctic air compared to the GFS

It's also very close to the Euro model as well!

Mean Euro Ensembles shows a trough with possibly cold air (Never shows the Temperatures) at +216 Hours, CMCE does not want to have much of it right now.
