cloudy weather, cloud up
曇 centers on the sky becoming overcast: cloudy weather or the action of clouding up. The idea is of the sun being obscured by clouds.
曇 combines 日 (sun) with 雲 (cloud), depicting the sun being covered by clouds. This is a straightforward semantic compound for cloudy conditions.
The sun 日 sits above a cloud 雲, but the cloud is so thick it covers the sun. That's why 曇 means cloudy weather or clouding up.
For ドン, imagine a dull, overcast day where the sun is gone: don -> ドン, and the sky is completely clouded over.
