Daisy's Aunt by E.F. Benson

It was about half-past three in the afternoon of the next day, and house and garden alike wore a rather uncomfortable air of heat fatigue and somnolence. The blinds were down in all the windows that faced south and west, with the object, no doubt, of keeping them cool -- a most desirable condition of things, but one, on the present occasion, but imperfectly realized. Nor were things much better to the east of the house, where ran the deep verandah in which they had sat and from which Daisy had strayed the evening before; for the heat came no longer from the honest and scorching rays of the sun, but through a thick blanket of grey cloud, which all morning had been gradually forming over and obscuring the sky. Southwards there was rather an ugly glare in the day, a tawny, coppery-coloured light that spread from low on the horizon, where clouds of thicker and more palpable texture were piled together -- clouds with hard edges and angry lights in them.

It was certain there was going to be a storm somewhere, and that would be no bad thing, for the air was horribly sultry, and quite distinctly needed clearing.
