Here is the QBO forecast, which is in easterly mode at the moment. But this forecast hints at a slight weakening of the -QBO.
Other things of note, the SAO jet is strengthening in it's current positive mode. Same with the jetstream over the Northern Hemisphere. This seems to somewhat correspond with the current +AO (stronger polar vortex), that is set to continue for the next 10 days at least, with longer term charts (GFS) showing a potential move to neutral AO.
EPS Control also shows a weakening of the easterly QBO jet over the 10-15 day period. Interesting, will the QBO follow fthe forecast? Will the 'failed' easterly phase happen again?
