Forgot to mention, especially for the newer members: this phenomenon is not atypical when it's overdeveloped AND the vertical extent of the cumuli is substantial: there is NO minimum vertical velocity required to form a cloud; thermals feeding an overcast can be very weak, even unusable. But if you are persistent and can get to cloud base...you can't get down. Because of the release of latent heat by the condensation in the cloud, lift at cloud base can be gangbusters...if you can get there.
Bottom line: patience.
