mammatus – The Amazing Sky

A stunning storm cloud retreats across the prairies leaving clear skies in its wake.

The timing could not have been better. On Monday night, June 17, a thunderstorm retreated to the east at just the perfect time to catch the light of the setting Sun.

As these prairie storms often do, this one left behind clear skies, with a quarter Moon at right to the south and the Sun to the west, off frame but illuminating this amazingly sculpted cloud. Downdrafts in the thunderhead produced the mammatus clouds – the bulbous structures hanging from the thundercloud. The low Sun angle emphasizes their form.

We’ve had a lot of rain and storms lately, but when a storm puts on as fine a show as this one, I’ll take it!
