Sadly that falls in a gap in my record keeping, but it was certainly in the opening weeks of the school summer holiday, so I should imagine it would be at some point in the first week of August.
This satellite image courtesy of Dundee University may provide a clue as it does show what appears to be MCS developments over the UK on the 6th . . .

Those small bright spots over east Kent looks the type that would have produced a hailstorm, which would just get bigger and bigger as it moves, I think, northwards, due to spreading Cb tops.
But certainly 5/6 August 1981 was the time of severe thunderstorms over central/southern UK, and it was caused by rapid reactivation of the weak cold front, moving erratically SEwards across the weak high pressure into a developing shallow low over northern France, that moved into southern UK. One MCS over central UK produced torrential downpours; 113 mm of rain fell in 24 hours from evening of 5th at Ringway and 132 mm near Tarporley (Cheshire). An another MCS produced severe lightning storms over London area; I think there were flood problems in the underground, and the morning was as dark as very dull rainy day in December and street lights had to be put on.
Yet the rest of August 1981 was generally dry with good deal of warm, sunny weather in the S and E of UK, although rather dull and wet in the far NW (but no thunder). It was very dry in the SW, with only 4.4 mm of rain in Camborne. There was some minor thunder activity in the far south on 1st, and over Wales on 29/30 August.
June and July, however, were quite rubbish summer months; it was largely cool and dull, with July being quite disturbed and thundery in the east, but June was mostly dry.
Going back on topic, I remember late April 1981 being very cold and wet when I was near Lincoln (and it was my 10th birthday), but it was much more of sleet rather than proper snow. It came after a spell of fine weather that dominated early April.
