Great Job!!!  You selected the sounding that is conducive to cloud development.  An expert would say that the balloon sounding corresponds to an atmosphere that is unstable.  Thunderstorms are very likely in this situation.  An unstable atmosphere is present when the temperature of a lifted parcel (bubble of air) is warmer than the surrounding air temperature. This can be seen by comparing the actual temperature profile (white line) with the path of the bubble or parcel (yellow line).  For this sounding the parcel temperature is warmer than the actual air temperature at any level, therefore its density is less than the surrounding air.  These conditions will result in bubbles of air rising in the atmosphere. Upward motions are responsible for cloud formation.
