Given the EIR is rather weather sensitive, I did make the suggestion before the FCL.008 NPA was published that for the EIR and was more appropriate than or, but it was too far down the road to publication. It would be a very fitting topic for a comment.
While I understand why changing it to "And" would make it safer, it would make finding such weather conditions quite difficult! Tempo and Prob30's are so common even on pretty find days, that not being able to ignore them at one airport (which the "or" allows you to do) would make the EIR quite restrictive.
