Been ages since I've posted a detailed thought on the model process. Based on the 06z ensemble, I wouldn't trust anything past the 3rd-5th of Dec. It's all over the place, so looking past the 5th is pointless.
The key timeframe is 120hrs onwards, to see how much warmth from the Gulf gets pushed up over Greenland. Once we have that in place, potential Wed-Thursday next week onwards for some low lying levels. IMHO, the zonal default as per usual post that Greenland High forming is no mans land. Let's wait and see. ^ It's volatile.
