Hi guys,
Yahoo Weather is best.it is free.Its one of the prettiest weather apps ever created and it very clearly inspired Apples own default app for iOS 7. Where the built-in app will tell you the current temperature and a basic short term forecast, Yahoo Weather includes advanced data such as wind speed, barometric pressure, and sunrise and sunset times. And it does it all in an attractive, easy to read manner that doesnt bombard you with confusing numbers and metrics.
Yahoo Weather presents the current weather conditions with images pulled from Flickr, and gives you everything you need in one, vertical scrolling column. It has hourly forecasts, five or ten-day forecasts, and detailed meteorological information for the current conditions. The iPhone version even has animated weather apps, but it lacks alerts for severe weather conditions. Its not nearly as powerful as Dark Sky, but its a great way to quickly find the basic information youll need for the day.
