Outside Temperature From an API in a Shell Script

I’m interested in collecting some internal temperature data from my servers to look at the effect of adding an NMVe drive. Last week we had a couple of warm days immediately followed by a couple of cool ones. I imagine a 20° ambient temperature change could effect the server temperatures, so I thought it would be good to add that to my temperature logs.

I don’t have a weather station or other automated system for collecting the temperature, but there are several commercial sources for this data which, while probably not as good as a sensor in the server room, will be fine for our purposes.
