A potentially record breaking heatwave from North Carolina thru PA next week, temps in the DC area could hit the upper 90's. This is all part of the overall pattern, where troughing in the west leads to ridging in the Central and Eastern US.
A Positive AO will get cranking in 15-20 days, NAO will flip flop for the near future, predominately negative. QBO about neutral right now, and is spiking very fast. QBO will be Positive by October 15th.
La Nina is really cranking, solid moderate right now, heading strong. A Kelvin wave may stall the cooling before it resumes when it passes. This thing is liable to be one of the strongest ever recorded. Becoming very west based, this thing is CRANKING!!!!!
