Openweather Intermittent Wrong Temperature Values Issue (search for "temp":7)
Raw
_Notes.md

Observations

The response data seems to originate from different source referred to by property "base" in the data record. What I noticed is that the bogus 7 degrees temperature values always originate from "base": "stations" while "base": "cmc stations" seem to provide correct values all times. It should also be noted that "base": "stations" sometimes provides correct values.
