1995> Atlantic , some interesting stuff, the SST of these July's wasn't even Atlantic-based
500mb going forward into August is time warp late July on models

Waves and stuff.. I once found with global currencies, when they move >1% in a day, the next down they were opposite 52% of the time, >10,000 examples.
+EPO's always overperform as temps.. that it's origins have been in spinning at 90N in arctic circle for 10 days is my only doubt though, It could be a stronger 90N vortex +timelag, vs the actual +EPO
15 day GFS ensemble mean hits it at like 85-90% for a stronger signal-pattern (>120dm in the mean). There are different intentions for different things.
