Hello

As usual, I'm turning to the font of weather knowledge that is
uk.sci.weather.

Where would I go to find out historic weather data for a specific date
and place, going back about 30 years?

I've been tasked with compiling a weather data chart showing how the
weather has changed on the day of the Great North Run since its
beginning.

By the way, this is for a projec.

Many thanks in advance

Paul
