Do weather changes affect the ionosphere in the lower layers that are

I rather doubt it as the D layer (lowest of the ionosphere) begins about 30

But there's been some recent discoveries that strong lighting strikes
have an upwards effect that goes about that high. (Buzzword: Sprites.)
And, I gather, there was a whole lot of lightning in that storm.
