Without knowing what software and/or website you were using to get those forecasts, I can't really answer your question.
The Met Office (
http://www.metoffice.gov.uk/) does however provide forecasts not just for the UK but for locations all over the world, and offers RSS feeds.
You should be wary of forecasts offered by organisations such as AccuWeather and the Weather Channel - they're not very good. The Met Office site also provides links to other national forecasting organisations around the world.
