Model: GFS

Parameter: Cumulus Cloud Depth

Looking at the Cumulus Cloud Depth parameter gives you an indication of just how deep clouds might develop for a given area. Where cloudbase is significantly lower than the absolute tops of the thermals, you might expect to see over-development of clouds in the area. Also note that this is simply the minimum cloud depth. Because the lapse rate changes once the air parcel is moist (dew point is reached) the actual cloud tops will likely be MUCH higher than is forecasted here.
