Venus and the brighter stars, like Arcturus, appeared shrouded in a veil this morning.
This was not mist close to the ground - horizontal visibility was excellent - but thin layers of high cirrus clouds. This effect has been used by navigators and travellers the world over as a sign that the a front may be approaching and a weather change is likely.
Cirrus on its own is not a guarantee of anything, but when followed, as it so often is, by cirrostratus and altostratus it is a strong indicator of an approaching warm front.
A weekend of sailing has just passed, one that was full of meteorological kindness.
Nature was generous in two ways over the weekend - perhaps as a reward for my having set up a page of weather lore?
Firstly, blue skies, fair winds and warm sun ruled over the Solent. Secondly, an approaching warm front signalled its intent, in line with meteorological science and common folklore, by sending a team of mares' tails ahead. These cirrus clouds would be followed by cirrostratus, altostratus and then the rain-bearing nimbostratus. A show was being promised, and then put…
Tonight's early evening sky is a feast of cloud types. Cumulus, passing low and darkened by the shade, perhaps the last of the fair-weather clouds for a bit. Higher there is cirrus, cirrostratus and altostratus all heralding the approaching warm front. Thrown in for a bonus there are some contrails from aircraft heading to and from the continent.
