Like most Dashboard widgets, these weather widgets show the value of acting like an explorer and clicking on the various parts of the widget to see what happens. Sometimes the effect is expected, like clicking on “Forecast” or “Radar” tabs, or the little 
button to display the settings page(s). But other times, it may not be obvious that clicking on part of a widget will do anything. Learn by exploring! Don’t worry, you won’t break anything.
It’s also sometimes unclear whether clicking on a word or button will change or open sections of the widgets, or open a web page in your default web browser. Again, you’ll never know until you try.
To help you choose the best weather widget(s) for you, here’s a summary of some of their features.
