In like a lion, out like a lamb

Do you know the origin of the weather proverb about March, "in like a lion, out like a lamb"? For most locations, the average temperature at the end of the month is higher than at the beginning, so the proverb typically has some meteorological truth to it, but where did it come from?

The phrase apparently has its origins with the constellations Leo, the Lion, and Aries, the ram or lamb. It has to do with the relative positions of these constellations in the sky at the beginning and end of the month
