Air Force Method of Forecasting Maximum Temperature (TMAX)
There are several ways to forecast maximum temperature from a single sounding. The Air Force developed a simple method to make such forecasts, depending on sky conditions. This method works for locations that are fairly near sea level away from water and not expecting an air mass change. We examine this technique below.
If no inversion is present between 4,000 and 6,000 feet above the surface:
