Available in the Nokia Store for £1, we took the hit for you and installed qooWeather:
From left to right: the city setup screen (there's no geolocation via Positioning/GPS, as far as I can tell) - many countries only have one city listed in the suggestions pick list, which is very disappointing - apparently you can tap in the text field and type in a city of your own, at least; qooWeather's main page, showing the main downloaded forecast and the choice of refresh frequency; finally, the qooWeather widget in place above the standard Nokia Maps Suite one
I have to say that I still prefer Nokia Weather - it's prettier and friendlier, plus it's also free, making it easy to recommend to all.
