No it isn't. It's worked fine for me since day one.
I wonder though...has anyone actually checked the weather in their area on accuweather.com to see if they match or not? That is where the widget get it's info from.
I dont know how often you look at the weather app, but so many people having issues clearly shows that the app is broken in sense 4. it hasnt rained here in the last 7 days but every morning I get up and its showing sunny with thunderstorm, and its doing it for more than one city. It cant be a coincident that 2 cities I have is showing the same forecast. And I've checked acuweather online and it shows the right weather.
Its not like this all the time, but its frustrating to now that the weather app may not be accurate when you are somewhere where you cant really tell what the weather is like
Edit:
Just took 2 more screen shots. Both cities Charlotte. One I added manually and one thats geting info based on location. As you can see the one that I added manually is showing forecasts for may around the same time the evo was released and the other one is showing the forcast for june
