First cumulus today popped at around 1240 BST with base 6,400

bases of 8,000. One chap reported a climb from 2,000 to 7,000 feet in
a mere 5 minutes - better than a fully laden Jumbo.

Jack, do you ever use the LGC at Dunstable? It's at the foot of 'my' hill,
now that I've moved. When I'm fully appointed, recording-wise, up
here I'll try to interest them in a little AWS down below ... unless, of
course, they already have one. Should make for some interesting
contrasts.
