Mammatus Clouds over Nebraska Astronomy Picture of the Day 2023 February 12

[Ptah]

Explanation: When do cloud bottoms appear like bubbles? Normally, cloud bottoms are flat. This is because moist warm air that rises and cools will condense into water droplets at a specific temperature, which usually corresponds to a very specific height. As water droplets grow, an opaque cloud forms. Under some conditions, however, cloud pockets can develop that contain large droplets of water or ice that fall into clear air as they evaporate. Such pockets may occur in turbulent air near a thunderstorm.

1. Beautiful, but, I'm in Nebraska and it's a bit past midnight

This is a day light picture? Today just became February 12, 2023. It's still dark?.... Oh, I understand now. The picture of the day doesn't mean it happened today. Ok, time to go to bed. Goodnight then.

2. The mammatus clouds pictured here were photographed over Hastings, Nebraska during 2004 June.

Thanks for reminding me. I used to check in on APOD every day for a little bit of science, but lost the habit. Always interesting.
