Thanks Brian. Can I ask where the weather observations data on the radar page is sourced from? It doesn't seem to be the same locations as on the Obs map?

Also a small bug report – the pressure readings don't display properly in my browser (Chrome on Mac) - it seems to have "1005" overlaid twice, with one set of narrower numerals sitting on top of wider ones.

Eg near me in north Hampshire the Obs map has data for Odiham, but on the radar map there is no obs for Odiham, but there are two others, both apparently on the M3, one near Fleet services and one near Lightwater. There are no weather stations in those places that I know of. Is it possible the location data for the overlay is wrong on the radar map?

Edit: The graphics glitch should now be fixed.

Precipitation type is now available on the radar feature here.

The images are generated using an API which gives the % chance of rain, sleet or snow on a 0.1x0.1 grid. It's very customisable, so hopefully it will improve as I tune it through the coming months.
