Cute, but inaccurate

I really love the original artwork in this app and Im obsessed with the color palette! Also the femininity of the aviator and clothing suggestions are really pleasing to the eye. However, the actual weather function is incredibly flawed. For instance, today the high in NYC is about 88 degrees Fahrenheit and the app has that correct. However, within the following 7 days, the apps weather is projected to be low 70-mid 60 degrees, while the actual weather will be in the mid-low 80s. Thats about 15 degrees off!! I dont get it.. Pls fix the accuracy of the weather so that this app is actually useable
