Re: Tornado Alley--To Paul
- as always you host the most fascinating discussions. i have been
sharing your commentary with a number of local friend's and indeed it
has inspired some spirited debate which as you know weather people do
best! thanks again and do suppose we shall get to see how it goes as
the months wear on! just hope NO ONE gets anything close to the
tornado of May 3rd 1999 in Moore OK as seen on TWC"s "Stormweek"
tonight... be well!
