Glorious weather!

The day dawns well! Sun, blue sky and even a few wispy cumulus clouds.
These clouds are caused by the sun warming the ground and setting off thermals that rise upwards and, depending on humidity and temperature, form into those fluffy summery clouds. In the winter the sun has no heat in it so these clouds cannot form. As winter wanes, one day these clouds appear, marking another phase of the seasons rolling forward.
