Full Screen Weather combines Weather Underground with Google Maps
In a nutshell, the web site does away with all those charts, photos, banner ads and other things you find on the Weather Underground web site. Instead you're presented with a map that takes up the whole browser window, courtesy of Google Maps. Just enter a location and Full Screen Weather will give you the current conditions and a brief forecast for your region.
But here's the cool part. You can also see the temperature in a number of nearby locations. Zoom in and out of the map to see more details, or click on any temperature to see the conditions for that area.
If you happen to have a 60 inch LCD display, you can also stand in front of it and point at different areas of the screen while telling your dog what the chance of precipitation is in each of the surrounding counties.
