Wrong temp in Phoenix
As a native Phoenician I can tell you with complete accuracy that it has NEVER been 35 degrees in July EVER! WTF? I was excited to install your app, but now not so much.
It is about 35°C (Celsius) in Phoenix now, shown by weather model (picker) and by all weather stations in the neighbourhood.
You were probably expecting temperature expressed in °F (Fahrenheit)?
You just need to select it in Settings.
