AFWA T2 Method
Compared to the T1 Method, the T2 method more completely accounts for the effects of the convective downdraft temperature. The T2 Method for determining the speed of the maximum convective wind gust is as follows:
As in the T1 method, estimate the direction of the mean wind in the layer between 10,000 and 14,000 feet AGL. This will be the forecast wind direction of the computed gust.
