Felly sgrifennodd Joe Egginton :
I think it was in January 2004, like you it's the first time I saw a
thunderstorm with heavy snow. It's quite unusual in this country,
because you need very cold air undercutting mild air.

Wow! I didn't realise I'd witnessed something so unusual last month, when
on 4th March I posted to here about thunder and snow. I feel privileged
now
