f2002- down here in London? Isn't London kinda in northern territory? btw, ironically, the exact same thing happened here in southern California... very hot weather on Thursday ("shorts" weather), but on Friday the temps plumeted.
Ouch... we don't have any drastic temp conditions, just the occasional e-quake, and where I live, numerous brush fires in the summer (in 1996, there was a 22,000 acre fire that nearly ate up our house... we had to evacuate 3 days in a row).
