The lowest level of the high density cloud winds may have two potential uses, 1.) assessing low-level shear trends, and 2.) determining low-level wind shear potential. You can see in the image below the green barbs are the high density cloud winds and the light blue obs are the actual 10m observed winds from ASOS and AWOS sites. There is a difference. Winds are more southeasterly in the actual obs and veer with height in the cloud density wind plots. The ceilometers at the ASOS/AWOS sites show bases around 3.5-4 KFT, and it can be inferred that this is approximately the level of the high density cloud winds. Although too deep to assess LLWS for aviation interests in this particular case, 0-1km shear trends can be inferred. This has potential application in severe weather forecasting by providing 0 AGL to cloud base shear values.
