I just had a thunderstorms with strong winds and rain, after that the sun came out and the winds were dead?

Question

calm, why would the winds be calm, there are no updrafts in the area? prior to the storms the gradient winds at the surface were strong , nnot related to thunderstorms

Answer 1

good for you. you survived another supercell

Answer 2

Actually, you either had a frontal passage... and behind the front you have a very weak gradient possibly for a moment..

Or maybe you didn't think about the gust front that preceeds a major thunderstorm which can increase winds sometimes well ahead of a storm.  This is part of the downdraft of a storm...  updrafts would have no effect on you with respect to surface winds.
