Question
Where do the winds come from in an elevated thunderstorm?  Is it from the strength of the winds aloft breaking through the stable layer near the surface?

Answer
Hi Mark

Since all thunderstorms require an updraft(s), the flow into regular and elevated thunderstorms mostly occur from below. A difference between a regular thunderstorm and an elevated one is that the inflow of air starts from a few thousand feet above ground for the elevated type. The reason the inflow starts from there and not from the ground level is that an inversion or a frontal boundary is blocking the lower level winds from being involved.
