Son of Weather Grok is an application that displays weather conditions and forecasts for cities from around the world. It taps into NOAA's (National Oceanic and Atmospheric Administration) data center using 4 letter ICAO codes for Airports. A web page to help you locate these ICAO codes can be found at: http://www.nws.noaa.gov/oso/siteloc.shtml
The ICAO is the code with the 4 letters. The codes that use numbers will NOT work. Keep in mind that some remote stations, like most in Afghanistan, do not work. Give it a try, but some of these stations never seem to report any data.
Son of Grok will show the temperature, sky conditions, humidity, wind speed, pressure, ceiling, visibility, and much more. Weather data is usually updated hourly from NOAA, and you can set Son of Grok to get this data at specified time intervals. The data is then displayed in an easy to read format using fancy-schmancy sky condition illustrations like you see on the news, along with the details in a small scrolling ticker and drop down list.
