    This reminds me of a similar storm one April in Bracknell, UK, nearly thirty years ago. This came in from the east along the Thames Valley from London with cooler air from the NE undercutting it. I was just leaving work when one flash and bang occurred and another followed when I’d walked about a quarter-mile home. I dashed for the nearest pub for cover. Nothing unusual about that, I suppose.

    A week or so later, someone was telling me he was working at Farnborough at the time. It was a sunny day but suddenly he glimpsed a flash out of the corner of his eye. He counted and got to 45 when he heard the thunder and the windows of the office rattled. A little while later he heard the second one and got to 44 as the thunder and window-rattling occurred. From these timings, he realised the flashes were about 11 miles away and probably near Bracknell. As it was during the time of the IRA bombing campaign, his first guess as to the cause was incorrect.

    Normally, you wouldn’t hear thunder from that distance – I’ve been under a few high-level storms where any thunder from frequent overhead lightning was mostly inaudible – but the ducting in this case was sufficient for the shock-wave to even rattle windows. Quite remarkable.

    That was fascinating. And yes, I’ve always wondered why i can hear WFAN sometimes all the way down to Florida.
