Displays historical weather data on segment efforts and activities
First you need your own Wunderground API (http://www.wunderground.com/weather/api) and Strava API (https://www.strava.com/settings/api) keys. Once these are set up, write them to your local storage by visiting Strava's website and running this in the console
localStorage.setItem('strava-weather-wunderground-key','<your wunderground api key>'); localStorage.setItem('strava-weather-strava-key','<your strava api key>');
Once this is done, you should have the API data necessary to make calls.
Clone this repo down. Open up Chrome, and go to your Extensions. Check the box "Developer Mode" and click the button "Load unpacked extension...". Navigate to this directory, and enjoy!

This might be true, which is why I also include a link to Wunderground's historical weather page on the mph/arrow.
