In a tropical cyclone, strong uplift of air pushes the tops of thunderstorms high into the troposphere. When that strength wanes, the cloud tops drop and become less cold. That's because the higher you go in the troposphere, the colder it gets. NASA satellite infrared data has revealed that Tropical Storm Tony's cloud top temperatures are warming and the storm is weakening.
