Welcome to the Arome high resolution numerical model. This model has a resolution of around 1.3km which is one of the highest resolution data sets in Europe and runs hourly out to 42 hours. We create the graphics in house here at GB Weather and this data is superb for smaller scale forecasting such as showers or thunderstorms and localised snowfall. This data also picks up on urban heat very well to give true reflection on the expected temperatures.
