Dave, I'm a big fan of this page and have bookmarked, but I'd like to make a suggestion for improvement. The sferics data at the top of the page (ATD data via the Icelandic Met site, I believe)shows sferics daily for the last 5 days (today's in red circles). Did you know that the Icelandic Met also have the same data displayed on a different timeframe i.e. for the last 24 hours, colour-coded into 3-hour segments? See here:
I think that the 3-hourly data would make a useful addition to the page (possibly more helpful for live tracking of "in-progress" convective outbreaks). Perhaps you could chop both the 3-hourly and daily feeds in half vertically i.e. show only the UK and Europe coverage on the right half of each map (we could all probably live without the knowledge of sferics that occurred mid-Atlantic or over Greenland) and tile them vertically on the page? Probably need to include the key for each map as well somewhere (particularly the 3-hourly map).
Otherwise, great page [y]
