This sums up the runs last night.

RC wanted to wake up to 5 pages!? He’s lucky there is 5 posts! :(
 
Since we don't actually have any legitimate threats to look at for the moment, let's reminisce in a big storm that happened OTD in 1955 that actually did not screw over the Triangle and was followed up by a couple more storms which also surprisingly weren't total screw jobs in RDU!

Sadly, this ended up being one of the few legitimately snowy winters of the 1950s, most of the rest of the decade sucked much like the 1990s!

Back to the Future! MCFLY!!!!
 

Look at where the SE Canada vortex is in later runs w/o a -NAO, it's all connected. In order to get a -NAO out of this pattern, you need the vortex in SE Canada to dig and push the corresponding storm track further south like it did in prior runs. Sustainable and strong negative NAOs occur often in conjunction with Atlantic-based SSWEs (here ours was in the Pacific which argues for transient, weaker -NAO) and particularly when a series of cyclonic wave breaking in the North Atlantic pushes the eddy momentum fluxes and waveguide to the south
