Today might well be the last day of summer.
I base this feeling on the SST anomalies in the the N. Atlantic
and the planetary scale waves which have locked into a 5-wave hemispheric flow pattern,
chart for 21st July given below as an example.
The 5-wave pattern is a mobile pattern and not conducive to blocking.
It is not surprising that the NWP models are not in agreement at 10 days out.
I hope I am wrong about the end of summer. 😕
