its really not that deep, the MJO is going to return to unfavorable phases(4/5/6) and therefore it retracts the jet
thus, we see the western trough/slight eastern ridge pattern setting up along with an -NAO(will prevent us from being super warm)
and as for concerns about slowed IO forcing, thats just going to be a byproduct of a weakening +IOD increasing convection in that area, we will eventually make it to 8/1/2, 30C+ ssts remain in both MC/IO and dateline
