So far the snow will blow in before the first of May.
Cloudy Sunset.

Witnessing storms to come woe and unrest.

Color.
Since the colors and duration of twilight, especially at evening, depend upon the amount of condensed vapor which the atmosphere contains, these appearances should afford some indications of the weather which may be expected to succeed. The following are some of the rules which are relied upon by seamen: When after sunset the western sky is of a whitish-yellow, and this tint extends a great height, it is probable that it will rain during the night or next day. Gaudy or unusual hues with hard, definitely outlined clouds, foretell rain and probably wind. If the sun before setting appears diffuse and of a brilliant white, it foretells storm. If it sets in a sky slightly purple, the atmosphere near the zenith being of a bright blue, we may rely upon fine weather.
