With a heavy thunderstorm over head, wind reports become unreliable as speed and direction can shift markedly within a few seconds. Use the reported wind as a guide to the intensity of the storm rather than a means of determining if it falls within limits as a 10kt headwind can soon become a 20kt tailwind. A rapid succession of differing wind reports from the tower should be ringing alarm bells on the flightdeck.
Aquaplaning may well have been a factor with such a high touch down speed.
I remember being told on my CPL ground school 30 years ago that if there was a thunderstorm overhead, "wait for half an hour", if you haven't got the fuel to do that then divert.
