A fine afternoon and evening on Wednesday with small amounts of cumulus and cirrus, followed by a mainly clear night. Visibility reduced at times in the northern quadrant owing to ongoing heath fires above Maerdy and Aberdare. Currently there is a small amount of cirrus, dense in places, excellent visibility and no wind at all. Minimum temperature overnight was 10.2 (0452z).

Lumpy altocumulus persists, although there must be a lid not very high above the layer as I can see some lenticular altocumulus too. Very warm and becoming increasingly humid. Excellent visibility, and a light ESE'ly breeze.
