@Gabz Last week there was one day where some apps showed forecasts for considerable rain while others predicted a nice day with sunshine. The doom and bloomers lost - it turned out to be a nice day. Since I prefer to exercise outdoors, figuring out the temp and rain forecast a day in advance is a key use case.
@ronguest @Gabz I cross-check by using the National Weather Service's web page, but I use Dark Sky as my main weather source. It's a bit inclined to over-estimate the highs and lows for the out-days, and then pull them in as the day approaches, but I find that suits me—I'm mentally prepared for the hot and cold days when they are as bad as forecast, but still well-informed as to what to wear today.
