If March comes in like a lion, it will go out like a lamb.
Weather folklore sayings are as colorful as our imagination.
While many sayings are based on careful observations and turn out to be accurate, others are merely rhymes or beliefs of the people who came before us.
Those people often believed that bad spirits could affect the weather adversely, so they were cautious as to what they did or did not do in certain situations.
Those beliefs often included ideas that there should be a balance in weather and life. So, if a month came in bad (roaring like a lion), it should go out good and calm (docile, like a lamb).
With March being such a changeable month, in which we can see warm spring-like temperatures or late-season snowstorms, you can understand how this saying might hold true in some instances.
We can only hope that if March starts off stormy it will end on a calm note, but the key word is hope. However, this saying seems to be simply a rhyme rather than a true weather predictor.
