Four plain lines on a cold north wind and snow-covered hills. A good one to reach for on an actual frosty morning.
From Mother Goose / Nursery Rhymes (traditional). See the whole collection.
Cold and raw the north wind doth blow,
Bleak in the morning early;
All the hills are covered with snow,
And winter's now come fairly.
