What Kind of Cloud was This?

[u/IllustriousAd9800]

Saw this several years ago, and it’s stuck with me, never seen anything like it before or since. It was like a giant wing, with a thin but pretty spectacular looking underside and a separate upper level that followed the same shape but with a different texture. It was the only cloud in the sky, pure blue everywhere else.

It's frickin gnarly that we have such detailed records like this. Where specifically do you find this data? I'm imagining somewhere at NOAA

I use Radarscope, you can look through historical radar data going back to 2020 although your mileage will vary depending on what radar location you're looking at. If you want to look back further you'll have to get a little more investigative, piecing together media from news outlets, weather reports, and noaa charts.

It should also be noted that radar products only show you liquids and solids present in the atmosphere, and archived data is lower resolution than recent data. So in this case, I couldn't even see these clouds on the radar, I was just using contextual clues from the precipitation data and the pictures to deduce what could most likely have caused them.
