Spots of rain

When leaving the house for a bike ride, or even to pop to Sainsbury's, it can be useful to know the location of the nearest rainclouds – not a weather forecast but information of where it's raining at that particular moment.

At work, I have unofficial access to decent-resolution research radar data unavailable to the public (sorry) but I've discovered that the Met Office offers a low-res (5 km) version for the entire UK, updated half-hourly, I think. One can zoom into regions, though the resolution doesn't improve.
