Data How to use sed to modify a line above or below matching pattern?

I couldn't figure out how to use sed or any other shell to do the following. Can anyone help? Thanks.

If seeing a string (e.g., TODAY) in the line,

replace a string in the line above (e.g, replace "Raining" with "Sunny")
and replace a string in the line below (e.g., replace "Reading" with "Hiking")
