This post finally (inadvertently) answered the question I searched far and wide for ... the yellow "drops" that accompany the blue drops are not yellow snow. On my desktop screen (3440x1480) those yellow things look drop-shaped ... from your enlarged screenshot it's apparent that they are lightning strikes ... which I definitely don't want to fly into (or eat for that matter). Both on the app and the website those things are so small I thought they were blue/white/yellow drops and really was confused.

FIrst, this is a beautiful website- idea, design, execution. I use it for aviation weather planning. You guys are talented. I'm a longtime web/mobile developer, but can't touch this.

Agree with your keeping the basic UI simple; there is a lot of stuff getting added, cool stuff (like comparing the models, this is just awesome), but please make sure it doesn't get bogged.

Regarding a 3d mode: would be best as option or even separate. Have you considered using cesiumjs for your globe? They have done a lot of the hard work already, and some of the capabilities might open up new opportunities (e.g. doarama).
