The outside air temperature affects your ride more than you might think. And, how that temperature relates to those above and below matters even more.
While stability and instability dont always cause weather, they leave a mark on even VFR forecasts in many subtle ways, and they influence everything from wind gusts to cloud layers. Even in forecast models, there are always complex equations that factor in stability. Stability is important enough that an entire chapter is dedicated to it in the FAAs Aviation Meteorology circular. For meteorologists, a chart known as the Skew-T diagram is used every day at forecast centers. Its literally a worksheet that helps forecasters visualize the days stability and make calculations on it.
