#2276 "Singleton Sunset Anvil"

I had been anticipating this thunderstorm all day. The flanking line of cumulus feeding into this thunderstorm cell was short but becoming increasingly more shallow and subdued. This thunderstorm was weakening with the sunset. There were striations in the southern flank of the updraft. The cloud at the tips of these tendrils was thinner and lacked the cumulus knuckles of a strong updraft. Fragments of the weakening updraft drifted along in the wake of the thunderstorm.

This cell moved well to the north of Singleton Lake but it looked much closer. It actually even passed to the north of Elgin. It died with the setting sun and we never got a drop from this line of convection.

The sunset colours were restricted to the lowest levels of the atmosphere. The pink band of cirrostratus on the western horizon looked like a typical deformation zone and foretold of more weather to come. The darker blues of altostratus hugged the horizon. The remaining bright oranges of the setting sun lasted only a few minutes. A couple of more thunderstorms actually did cross Singleton overnight and brought 10 millimetres of much needed precipitation in short and heavy downpours.

A light seems to be on all night. I included the unnecessary stab of Titanium white on the dark western shore of Singleton. It was already on before the thunderstorm passed by well to the north. Human pollution comes in all forms including light.
