There is no shortage of weather apps for iOS. On the Mac side, things are a bit more sparse, so I welcomed the arrival of Weather Tab Pro, a US$2.99 app for OS X.
The app lets you create a list of cities, and then you can scroll an animated graphic between them. You'll get local time for each city, temperature, humidity, winds and an extended forecast. Weather Tab Pro also lets you choose from among nine skins for the weather display. It sources weather information from World Weather Online, and the developer told me he hopes to add at least one additional provider.
There are a few rough edges to this app. Initially I could not find it in my application folder. Turns out it has a different name. It's called SuperWeather. That's going to confuse some people. The developer says the error was caused by a last-minute name change, and will be fixed in the next version. You also have to set it to run at startup on your own. There is no option in the app preferences to handle this.
