The aviation weather people typically don't provide info for clouds above
12,000'. Basically what they're saying is that they aren't forecasting for
clouds to occur, but maybe there will be some above 12,000'.

That's not what they are saying. If they forecast no clouds, then they are
forecasting no clouds. There's no "maybe there will be some", except
inasmuch as the forecast itself is subject to being inaccurate.
