(please forgive me is this question is naive - I've gone from not knowing
anything about METARs to my current knowledge in about 40mins whilest doing
other things as well)

In a typical METAR reading there can be more than one entry for the cloud
conditions, ie: ... ... ... ... SCT025 BKN040 ... ... which would indicate
scattered cloud at 2500ft + broken cloud at 4000ft (I think). My question
is: is there a limit to how many cloud entries there can be?
