My back garden had 9mm.

One of us has to be wrong.

Impressive if they can measure it to the nearest 100th of a millimetre.
It equates to almost double the UK record for a day's rainfall, so it
seems unlikely to be right. Maybe one of the pupils got creative with a
watering cam.

Thunderstorms can give very localised heavy rain, so I wouldn't rule it
out on those grounds, but just on the sheer size of the Pitsford School
total.

I suspect that it's an Instromet station currently, which uses a drop
counter to a resolution of 0.01mm. But there's clearly an issue with the
apparent total.

Emailed them asking if it was true, and got this reply.

"Yes, this is an occasional software problem. I'm afraid I will not be
able to correct it until Friday morning as I am away. However, the
station has plenty if other rainfall recording devices to obtain an
accurate record."

School's on holiday now, so they are relying on the automated recording
of all the data. It's not the first time something like this has
happened. Once a return of 0mm was posted when we had the mother and
father of a thunder storm. Apparently the local pigeons had left their
own message inside the equipment!
