Hi all,

I have a question that a friend of mine and I were wondering about
tonight. We live in Norman, Oklahoma (near Oklahoma City) and we live on the
top floor of a 12 story building. In the morning, we notice that my TV
antenna picks up signals from 200 or 300 miles away, but around 9 or 10,
those signals begin to fade and they don't come back until the next morning
around the same time. What causes this? We've noticed that we're able to
pick up stations in Dallas and sometimes as far away as Arkansas. This has
been puzzling us for quite some time. I don't know if there's a
meteorological reason for this, or if it's more on the physics side.

Thanks.
Dave
