That's the problem (thank you for posting the link): but it
gives a
reading for Oklahoma City but not for Guthrie.

The zip is 73044; is there someplace I can plug in the zip?

Sorry if I'm not seeing it..

Is this better?

If all else fails I would go conservative and say zone 6. Better

Remember this is a minimum temperature rating so if you are
talking about summer annuals it don't really matter.
