&gt;Using crowdsourced reporting, readings from the barometric pressure sensor in the iPhone 6 and latest iDevices, and predictive algorithms that overlay all that information on a map to deliver 18-hour forecasts, Sunshine generates what Stroponiati calls &quot;weather forecasting at the street level.&quot;<p>So no.  This was one of the really cool things predicted, if not explicitly mentioned, when Apple announced new iPhones would have a barometer; hyper-local readings can only improve weather information, which is sorely needed.
