Low Level WInd Shear Probabilities

We are evaluating two ensemble forecasts of low level wind shear (LLWS). LLWS is one of the hazards that are forecast as part of our turbulence package.  Both the AFWA and SREF have been post-processed to produce a probabilistic forecast of low level (0-2000 feet AGL) greater than 30kts.

09Z SREF run on 19 Feb, LLWS probabilities between 21Z Feb 19 - 09Z Feb 21.
12Z AFWA run on 19 Feb, LLWS probabilities between 21Z Feb 19 - 09Z Feb 21.
