#MEwx Today's Weather Proverb

“The moon, her face be red, of water she speaks.”

The color of the moon — particularly when it’s full and rising — can be an indicator of incoming weather systems. In a dry atmosphere (indicating good weather), the moon is seen as white. When the atmosphere begins to collect moisture, molecules in the air scatter light differently than in a dry atmosphere, and the moon appears redder.

This moisture that is making the moon look red can be a sign of rising humidity, meaning coming rain showers.
