This is a demo project to check today's weather conditions at your location. Location is discovered through html5 geolocation falling back to geoip if the user does not want to disclose location. Weather is provided by weatherunderground API. If there's a chance of rain a Yes will be displayed on screen. If weather promises to be clear a No. The project is just a demo, but if anyone really cares about it it is easily exapnded into something robust.
