I’m still amazed with the wide discrepancies in weather forecasts based on the source of information use by weather apps.
I’m a recent “convert” to Carrot weather–mainly for its customization and the additional data that can be added.
But, if one’s objective is the most accurate forecast, it can be difficult to settle on a weather app, at least for me. Here are examples from my location:
Carrot Weather-source: Dark Sky
What is odd about this screenshot is that Dark Sky predicts heavy rain (consistent with the other forecasts) but does not show it on the rain “graph.” That said, I may well be misunderstand that graph but my assumption is that it would show the probably of rain. It seems to but at a much lower level than the statement “Heavy rain tonight” implies.
Carrot Weather-source: AccuWeather
Carrot Weather-source: Foreca
Apple Weather-source: The Weather Channel
Notice also the wide variation in reported humidity: from 52% to 76%. (Apple Weather reports it at 57%). I’m sitting outside while I write this post. It is very comfortable, which “tells” me the humidity is 60% or less.
Examining these examples carefully, it seems to me that Carrot Weather with AccuWeather as the source is the closest match to Apple Weather with The Weather Channel as the source. They are relatively close in the high, the humidity, and the probably of rain.
Which leads me to conclude that Carrot Weather + AccuWeather is likely the most accurate while also providing the most customization.
Huh, this was a helpful post to write–I think it helped me come to a conclusion. Writing does indeed help one’s thinking!
I think I’ll post this anyway–maybe it will be helpful to someone else, or merely amusing at my expense!
