The randomness of temperature measurements.
At this minute, the weather source provided via Microsoft says it is 105 degrees F here.
At this same minute (from the time stamp) the NWS says the temperature is 108 degrees F.
Accuweather reports it is 106 degrees and the Weather Channel 105 degrees and WeatherBug reports it as 104 degrees.
Seems like such a simple thing to have standards so that regardless of who is asked for a city’s temperature, some consistency is provided. Just seems really weird.
