Artist's high clouds (6)

I believe the answer is:

strati

'clouds' is the definition.
(stratus is a kind of cloud)

'artist's high' is the wordplay.
'high' is an anagram indicator (like drunk).
'artist' with letters rearranged gives 'STRATI'.

(Another definition for strati that I've seen is " Grey layer clouds".)

I've seen this clue in The Guardian.
