How to be weather-wise.
--Whether clear or cloudy, a rosy sky at sunset presages fine weather; a red sky in the morning bad weather, or much wind, (perhaps rain;) a grey sky in the morning, fine weather; a high dawn, wind; a low dawn, fair weather.
Soft looking or delicate clouds foretell fine weather, with moderate or light breezes; hard-edged, oily-looking clouds, wind.
A dark, gloomy, blue sky is windy; but a light, bright blue sky indicates fine weather.
Generally, the softer clouds look the less wind, but perhaps, more rain may be expected; and the harder, more greasy, rolled, tufted or ragged, the stronger the coming wind will prove.
Also, a bright yellow sky at sunset presages wind, a pale yellow, wet; and thus, by the prevalence of red, yellow or grey tints, the coming weather may be foretold very nearly; indeed, if aided by instruments, almost exactly.--Small, inky-looking clouds foretell rain; but if alone, may indicate wind only.--High upper clouds crossing the sun, moon, stars, in a direction different from that of the lower clouds, or the wind then below, foretell a change of wind.
When sea-birds fly out early, and far to seaward, moderate winds and fair weather may be expected; when they hang about the land, or over it, sometimes flying inland, expect a strong wind with stormy weather.
There are other signs of a coming change in the weather, known less generally than may be desirable, and therefore worth notice; such as when birds of long flight, rooks, swallows, and others, hang about home, and fly up and down, and low — rain or wind may be expected.
Also when animals seek shelter places, instead of spreading over their usual range; when pigs carry straw to their styes; when smoke from chimneys does not ascend readily (or straight upward during calm), an unfavorable change is probable.
Dew is an indication of fine weather; so is fog. Neither of these two formations occur under an overcast sky, or when there is much wind.
One sees fog occasionally rolled away, as it were, by the wind, but seldom or never formed while it is blowing.
