The weather business is garbage. Whilst ATC have an 'appreciation' of the weather' in their airspace, they aren't actually up there..If an ATC vectors an aircraft towards weather the expectation is for the PIC to pipe up and say so. Not one rated controller in this country would, on receipt of that advice, continue that vector. If ATC descend aircraft into cloud that they are told about, its because any other option would cost you time and there is no other vertical choice separation wise. Any suggestion otherwise is pure slander.
