Tempature Variance – Yahoo Weather Review

The thing is I prefer the yahoo weather app layout over every other weather app. But the temp always varies by up to 5-6 degrees than what is is being posted locally (NWS,Airport,etc). The app does not indicate where they get their data from. Is it guesstimated? I’ll stop using the app if data not reliable.
