How to Determine Which NFL Games Will be Televised in Local Markets?

I travel a lot for work and would like to know in advance which NFL Games will be televised in the local market that I'll be traveling to. Is there any where on the web that has that information? For Example, if I know 1 weekend i'll be in Colorado and next weekend I'll be in Texas. How can I know which games will be on TV locally? It seems the only games I can find for sure are the nationally televised games like MNF. Thanks
