This little widget shows a handy current-conditions display for your city (or any other city), and, at your option, even offers a six-day forecast.

Before you get started, the most important step is to tap the button at the lower-right corner. The widget flips around.

On the back panel, shown below on the right, you can delete the sample city (Cupertino, California, which is Apple's headquarters) by tapping and then Delete. And you can add your own city, or cities of interest, by tapping . The Add Location screen and keyboard appear, so you can type your city and state or Zip code. You can rearrange the sequence of cities by dragging the grip strips up or down.

When you tap Search, you're shown a list of matching cities; tap the one whose weather you want to track.

When you return to the configuration screen, you can also specify whether you prefer degrees Celsius or degrees Fahrenheit. Tap Done.

Now the front of the widget (above, left) displays the name of your town, today's predicted high and low, the current temperature, a six-day forecast, and a graphic representation of the sky conditions (sunny, cloudy, rainy, and so on).

There's nothing to tap here except the icon at lower left. It fires up the Safari browser, which loads itself with Yahoo's information page about that city. Depending on the city, you might see a City Guide, city news, city photos, and more.

If you've added more than one city to the list, by the way, just flick your finger right or left to shuffle through the Weather screens for the different cities on your list. The tiny row of bullets beneath the display correspond to the number of Weather cities you've set up—and the white bold one indicates where you are in the sequence.
