Toposhperic what?
 

I get good reception on all my digital ota channels.
For some reason, lately (summer), channel 2 CBS does not come in during the morning hours, but does fine the rest of the day.
Even in the morning when I see a blank screen, the signal strength is nearly 100%.
I'm thinking this is the station more than anything else?

We have no clue what "channel 2 CBS" might be, you have to provide relevant details with your questions.

That is probably strong, local electrical interference.
