They must be freezing in the Chicago area right now. With current temperatures below -20º F – and even lower in the next few days - I wouldn't dare set a foot outside home!
So, where do I get all this information from? Easy: download Weather Spy and you'll have your own personal weather forecast right on the Windows desktop. You'll be able to check weather conditions in thousands of locations worldwide, including temperature, rain probability and wind speed. The program also features satellite imagery with which you can see clouds over the US or Europe, as well as check temperatures and precipitation probabilities. Only one location can be checked at a time, though.
Weather Spy includes a fairly complete configuration menu where you can choose measurement units, apply a transparency effect to the program's window and tweak other settings. It would have been great to have some interface skins too, as the wooden appearance doesn't really fit the program.
If you need to check weather conditions in a certain location anywhere in the world, Weather Spy is the tool you're looking for.
