A ring around the moon is a prediction of rain or snow to come.
Last 7 Days
Cloudy mornings turn to clear evenings.
Expect rain if a mule rolls in the dirt at midday.
The calling of cicadas foretells dry weather and that frost will come in six weeks.
When the moon has a white look, or when her outline is not very clear, rain or snow is looked for. - Scottish saying
Place an egg laid on Good Friday under a bowl in your attic to ward off lightning strikes.
One fair day in winter makes not birds merry.
When snow falls in the mud, it remains all winter.
