The colour version of previous shot .. I really like the drama of these clouds. Only there for a brief moment before the disappeared.

We've probably all had one of those moments when just as you're ready to photograph a flower, pet or just about anything, a dark cloud suddenly appears, thereby obscuring the sun.

A big hail-producing storm battered north Texas yesterday with egg-size up to baseball-size hail, causing much damage to homes and cars. I don't know whether the egg comparison is that of a hen, duck or dinosaur egg \O/
All that remains of a cloud, arced over a setting sun on a spectacular winter afternoon.

Cumulus cloud
Small cumulus humilis clouds floating over cloud that can have noticeable vertical development and clearly defined edges.
Cumulo- means "heap" or "pile" in Latin. Cumulus clouds are often described as "puffy", "cotton-like" or "fluffy" in appearance, and have flat bases. Cumulus clouds, being low-level clouds, are generally less than 1,000 m (3,300 ft) in altitude unless they are the more vertical cumulus congestus form. Cumulus clouds may appear by themselves, in lines, or in clusters.
Cumulus clouds are often precursors of other types of cloud, such as cumulonimbus, when influenced by weather factors such as instability, moisture, and temperature gradient. Normally, cumulus clouds produce little or no precipitation, but they can grow into the precipitation-bearing congestus or cumulonimbus clouds. Cumulus clouds can be formed from water vapor, supercooled water droplets, or ice crystals, depending upon the ambient temperature. They come in many distinct subforms, and generally cool the earth by reflecting the incoming solar radiation. Cumulus clouds are part of the larger category of free-convective cumuliform clouds, which include cumulonimbus clouds. The latter genus-type is sometimes categorized separately as cumulonimbiform due to its more complex structure that often includes a cirriform or anvil top. There are also cumuliform clouds of limited convection that comprise stratocumulus (low-étage), altocumulus (middle-étage) and cirrocumulus. (high-étage). These last three genus-types are sometimes classified separately as stratocumuliform.
Formation
Cumulus clouds form via atmospheric convection as air warmed by the surface begins to rise. As the air rises, the temperature drops (following the lapse rate), causing the relative humidity (RH) to rise. If convection reaches a certain level the RH reaches one hundred percent, and the "wet-adiabatic" phase begins. At this point a positive feedback ensues: since the RH is above 100%, water vapour condenses, releasing latent heat, warming the air and spurring further convection.
In this phase, water vapor condenses on various nuclei present in the air, forming the cumulus cloud. This creates the characteristic flat-bottomed puffy shape associated with cumulus clouds. The size of the cloud depends on the temperature profile of the atmosphere and the presence of any inversions. During the convection, surrounding air is entrained (mixed) with the thermal and the total mass of the ascending air increases. Rain forms in a cumulus cloud via a process involving two non-discrete stages. The first stage occurs after the droplets coalesce onto the various nuclei. Langmuir writes that surface tension in the water droplets provides a slightly higher pressure on the droplet, raising the vapor pressure by a small amount. The increased pressure results in those droplets evaporating and the resulting water vapor condensing on the larger droplets. Due to the extremely small size of the evaporating water droplets, this process becomes largely meaningless after the larger droplets have grown to around 20 to 30 micrometres, and the second stage takes over. In the accretion phase, the raindrop begins to fall, and other droplets collide and combine with it to increase the size of the raindrop. Langmuir was able to develop a formula which predicted that the droplet radius would grow unboundedly within a discrete time period.

THIS IS A FIRE RAINBOW - THE RAREST OF ALL NATURALLY OCCURRING ATMOSPHERIC PHENOMENA.
CLOUDS HAVE TO BE CIRRUS, AT LEAST 20K FEET IN THE AIR, WITH JUST THE RIGHT AMOUNT OF ICE CRYSTALS AND THE SUN HAS TO HIT THE CLOUDS AT PRECISELY 58 DEGREES.
Thanks to mariamiller18 for finding this cool tidbit above.
I've seen this phenomena maybe 4x since I've taken up photography but this is my best capture. It must be from a rainbow but it looks more like its shaped with the cloud. I just think its mesmerizing. Used a circular polarizer to bring out the details.
I walked outside after hearing the thunder. Clouds rose from the distance seeming full of water waiting to release.
Just then I looked straight above and saw a huge cloud heading towards a collision course with another.
If only for a moment I was a kid again, smelling the new rain and feeling so small in the world. Dang, it was only a moment!
