nice 1038 CAD, 39/40 degrees at peak "heating" during the day with a storm approaching, its looking like its gonna be at night on this run which would only help, especially CAD areas
 
The pac goes to hell on the Euro and cold air supply shuts off. Still a 1040HP in that spot you would think it would be a major ice storm but it's confined on the Euro to 85 west in NC. You had the pac on the GEFS with the Euro southern low track you would have something special.

So many things that are allllllllmost right for this. At least we've got somewhat more of a signal for something now

Still if you take a blend of both models.. CAD areas should actually start to pay more attention.

Personally I think the Op Euro is wrong for eroding the pac ridge as we've seen that before. But the GEFS is unbelievably cold...which we've all seen many many times.

The second system may end up really nice as we get closer.

The Euro will be shot after shot with systems sliding down that massive western ridge. That 588+dm ridge likely will not be going anywhere quickly.
 
What the heck...both valid next Saturday. I know...op v/s ens, but still.

The Euro ensemble is trending heavily in our favor for a winter storm next week w/ increasing stream separation over the western US around day 4.

That looks great! Is there any way to keep our high pressure from escaping so quickly? Looks like the NAO will not be any help. No 50/50 either. I guess all comes down to perfect timing? That is so often the case.
