Dark Sky for MacOS via Alfred
Dark Sky is a hyperlocal weather platform with down-to-the-minute forecasts for your exact location. Originally created for the iOS platform, Dark Sky also has a web interface to bring you hyperlocal weather on you Mac.
This Alfred script allows the user to either provide a ZIP code or use their Mac's GPS chip to get the current weather for their location. This script launches the the Dark Sky web app for the coordinates of their current location or the provided ZIP code.
This only supports US ZIP codes and future integration with the Google Maps API would be useful for expanding support to other countries.
