This is awesome, but what would be even better, and really, really valuable as a next feature would be hail and near-term hail forecasts and warnings. It seems like there may be some model development needed (especially going forward), but just integrating the already-existing lightning and radar data to display hail presence and near-term probability would be a huge win.

The right-hand menu is awkward - right now, it collapses, but leaves a tag hanging out over the map that takes considerably more space than just leaving the icon up (especially for things with longer names, like "Temperature". I'm not convinced that having it vanish automatically is good. After using it a bit, I think I preferred the old behavior, where the arrows slid it out of the way until you opened it up again. I love the performance improvements in the new version, but I think in general, the UI changes are a step backwards.

@ivo Depends on your browser - there's some slight benefit to putting this in the app...

Just started trying the Beta. I notice you're open to suggestions about color schemes for the various metrics. Here's some of what I've learned about that over the years: There is a real art to doing this well - I've built complex graphics for visual data analytics several times, using different methods. my favorite is a seven-color scale (where you can get away with that little resolution): Low Critical - Magenta, Low Warning - Blue, Nominal - Green, High Warning - Yellow, High Critical - Red, Old /Possibly unreliable data - Gray about 20% off BG color. You can get away with squeezing a few more colors in there, but not too many. One of the issues with this is that although it's relatively "stoplight intuitive", it's tough on colorblind users (nearly 10% of population), esp. since red-green is the most common type, so confusion there can be really dangerous. If you want a tool to help you play with and explore some more complicated schemes to convey different kinds of info and even check for colorblind-safeness, check out http://colorbrewer2.org. (Note that you may want the "diverging" option for many of your color schemes...) I wish there was a way to specify the baseline schemes to modify, but most of what's there is decent as a starting place, if not always the most attractive aesthetically. Hope this helps!
