The NWS- Quad Cities has released new storm damage data for the derecho on 8/10/20. The new data suggests winds may have reached 140 mph based on damage to an apartment building near Cedar Rapids, IA. New storm reports have been added to the SPC storm reports for a recorded wind gust of 126 mph in Atkins, IA. A 340 foot tall antenna which was rated to withstand winds of 125 mph was also toppled near Van Horne, IA.

I don't think any of us can picture a squall line producing winds of 140 mph. I've never heard of one coming anywhere close to that strength. To me this begs this question, was this the most powerful MCS/derecho on record?
