Howells on "in like a lion, out like a lamb"
Rhinelander Daily News:
Through the years, March’s trademark blustery winds and changeable weather have earned it several terms and expressions. There is an old saying we still hear that March “comes in like a lion and goes out like a lamb.”
The expression may have been inspired by poet William Dean Howells who wrote: “Tossing his mane of snows in wildest eddies ... Lion-like March cometh in hoarse.”
