This is one hell of a +ve AAM surge.
Note the renewed pool of negative anomalies now working poleward, this could be heatwave number 4, add in the usual lag and you’re looking at around the 21st-25th July.
As these anomalies propgate poleward they work to amplify subtropical ridges i.e Azores high.
This summer is running a real risk of being an absolute classic, the reload of settled / hot weather is already in sight, any relaxation (if any) in this pattern is looking increasingly short lived.
