On WeatherCAN app (iOS) on the iPhone, here is an amusing situation in which the current temperature at 14:58 is +20 C, but the forecast for 15:00 is +29 C, a whopping increase of 9 C in 2 minutes! I suspect that the measurement/reporting interval is 1 hour.
Apple Weather app (iOS) on the iPhone also exhibits such a transient phenomenon, from the current temperature of +32 C at 21:19 to the forecast temperature of +23 C at 22:00, a whopping decrease of 9 C in 41 minutes.
Apple Weather app (iOS) on the iPhone also exhibits such a transient phenomenon, from the daily low temperature of -6 C at 18:00 to the daily high temperature of +2 C at 19:00, a whopping increase of 8 C in 1 hour, most probably due to simulation glitch.
Apple Weather app (iOS) on the iPhone also exhibits such a transient phenomenon, from the temperature of + 20 C at 20:00 to the temperature of +9 C at 21:00, a whopping increase of 11 C in 1 hour, most probably due to simulation glitch.
Here is naturally-extreme temperature change in Apple Weather app (iOS), from the daily high temperature of +22 C to the daily low temperature of +2 C, i.e., a whopping derease of 20 C in 14 hours!
