GFS stands for Global Forecast System and is a US-developed weather modelling system said to be better than the forecasts used by the Met Office.
If you're a registered member of this site - and have included your postcode - you can get instant 48-hour and 7-day forecasts for your city.
Your postcode is stored in our database and means you're always just one click away from instant weather forecasts, an invaluable tool for both bike rides and likely till traffic.
The weather feed is supplied by Metcheck.com. It's UK only at the moment.
And, no, we will not be offering a pizza delivery service next...
