Snow by Uri Shulevitz
"It's snowing," said boy with dog.
"It's only a snowflake," said grandfather with beard.
The boy and his dog are excited and go out to see the snow. Other voices - a man, a woman, the radio, the TV - say no snow. The boy with the dog knows it it snowing.
But snowflakes don't listen to radio, snowflakes don't watch television. All snowflakes know is snow, snow, snow.
People go inside as the snow falls. The boy and his dog play in the snow - joined by some storybook characters from a bookstore. The snow continues until the city (once gray) is covered in white.
Snow is a Caldecott Honor Book. This is a good picture book to share on a snowy day (or on a day you are hoping for snow).
