When looking for a weather app most of the people considering a beautiful weather widget with or without a clock. I am one of them, i am always like to have a weather widget in my SGS2 home screen.
If you search for a weather app or widget you will get many result. I recommend Go Weather EX. My personal experience with Go Weather EX is very good, i am from India and i am always getting the accurate weather update. They provide weather updates on thousands of cities.
According to Developer Go Launcher EX Features are:
-Weather detail today
-The weather condition in the next 24 hours

Before 7 / July / 2012 the weather widgets were available only for Go Launcher EX. Now they updated with system widgets that means we can use the Go Weather EX widget with any launcher.
