Now see here you American chaps! I live in Yorkshire, England, and I keep clicking the Nexrad weather display button on my PiAware only to find we don’t have the right kind of weather here. Apparently it’s only for US users!
Can we (you) add a regional weather feature for places other than America? Believe me, here in Yorkshire we have plenty of weather and it would be great to see it overlaid on my display.
Do you have a freely available source of weather tiles that are suitable for an overlay? That is the usual stumbling block. If you do have a source of tiles, then adding another layer to the map is relatively easy.
